I have decided to recreate a game I was making on the PC for Google Android but I have run into some snags. Currently I have the menu partially created but am not exactly sure how the views and such work. So I have uploaded my source and was hoping someone could look at my source and help me. I have menu created through xml and have ninepatchdrawable button with a background set for the menu. What I am trying to figure out is clicking start and going to another view.

Thanks! I hope I can get some assistance
I am also having some trouble installing it to my att Samsung Captivate. I tried using a program I have been using to install from the pc but it says wrong SDk version even though it is the same one I have been using.
Please Help?
look at this: http://dl.dropbox.com/u/2817943/T Dodger.rar
i have added an additional layout and an acitivity-class to your project. and i called that activity by clicking you start button!
i hope that helps you
Thanks that helps a ton! That was the main issue I was having. Now I can start connecting parts of my game together. I appreciate it a ton.
Also just a tip, root your captivated and turn on USB debugging. That will allow you to run your program right to your phone, rather than the slow emulator.

Okay that sounds good. One thing though that voids your warrenty and I bought an extended warrenty from At&t. So would it void my warrenty?
Also I am making some progress. I have the code laid out for detecting the accelerometer! Next I just need to use that data and apply it to the image that I will be moving around the screen.
It will not void warrenty as it is software based. Sounds good. Hope to see a beta soon.
Okay sounds great then. I will start working on that then.
I have run into another little problem. Now I have rooted my phone which makes testing a LOT easier! (Thanks Metastable!)
The following code seems to cause it to crash:
package com.bobhoil.tdodger;
import android.app.Activity;
import android.os.Bundle;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.widget.TextView;
public class TestActivity extends Activity implements SensorEventListener {
private TextView accelXValue;
private TextView accelYValue;
private TextView accelZValue;
private SensorManager sensorManager = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
setContentView(R.layout.test);
accelXValue = (TextView) findViewById(R.id.accel_x_value);
accelYValue = (TextView) findViewById(R.id.accel_y_value);
accelZValue = (TextView) findViewById(R.id.accel_z_value);
accelXValue.setText("0.00");
accelYValue.setText("0.00");
accelZValue.setText("0.00");
}
public void onSensorChanged(SensorEvent sensorEvent) {
synchronized (this) {
if (sensorEvent.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
accelXValue.setText(Float.toString(sensorEvent.values[0]));
accelYValue.setText(Float.toString(sensorEvent.values[1]));
accelZValue.setText(Float.toString(sensorEvent.values[2])); }
}
}
public void onAccuracyChanged(Sensor arg0, int arg1) {
}
@Override
protected void onResume() {
super.onResume();
sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_GAME);
}
@Override
protected void onStop() {
sensorManager.unregisterListener(this);
super.onStop();
}
}

This is supposed to capture movement through the accelerometer.
please zip the eclipse project and tell us the link to it.
i'm too lazy to build my own xml with 3 EditText's
OKay here is the link: http://www.bobhoil.com/wp-content/uploads/2010/09/T-Dodger2.zip
I have been busy working and hadn't had a chance to upload it.
Don't mean to be persistent I am just trying to figure out why it is crashing. I changed the code in the above file to some ibm examples just to test if that worked and it too seems to crash. Am I starting the activity wrong?
there are some attributes missing in your test.xml (android:layout_width... and so on)
here is the correct test.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<ImageView

android:layout_height="wrap_content"
android:src="@drawable/mobil"/>
<TableRow android:layout_width="fill_parent" android:layout_height="wrap_content">

android:id="@+id/accelerometer_label"
android:layout_column="1"
android:text="Accelerometer"

</TableRow>

android:text="Z:"
android:textSize="8pt"
android:padding="3dip" />
<TextView
android:id="@+id/accel_z_value"
android:gravity="right"
android:textSize="8pt"
android:padding="3dip" />
</TableRow>
<View
android:layout_height="2dip" android:layout_width="fill_parent"
android:background="#FF909090" />
</LinearLayout>
by replacing the test.xml with the correct one, the activity opens like it should (you can check that by adding a breakpoint in the onCreate method).
But there is another error too that will cause the activity to close immediately. At the moment i have no idea what's the problem, but i try to figure it out!
Okay thanks. I have been trying to solve the problem for about a week now. I am having a hard time figuring out the problem.
EDIT:
Okay after doing some research maybe it is getting information from the accelerometer to quickly?
no, the problem is the test.xml again... something is wrong with your table-rows.
while executing your application, logcat shows some exceptions like "null-child" in a table row...
Code:
09-05 07:45:40.114: ERROR/AndroidRuntime(223): java.lang.NullPointerException
09-05 07:45:40.114: ERROR/AndroidRuntime(223): at android.widget.TableRow.measureNullChild(TableRow.java:182)
I'm afraid I have too little experience with <TableRow> in Android. I suggest to use simple <TextView> elements to display the sensor data. You only need one TextView, and in your java class file you can put all the sensor values in this TextView.
for example:
accelValue.setText("Accel X: " + values[0]+"\n" + "Accel Y: " + values[] +.....)
The TestActivity is for testing purposes only... so don't care about the layout
Okay I will change over to using TextView and see then if I can get something up and running.
Thanks for the help! I have finally got it fully working!
OKay one last question. Is there any way to change android:layout_y outside of the xml? From the activity?
Have you set up your activities in manifest.xml file??

Hi,
i am new to developing apps on Android (Windows Phone 7 dev)...how ever i have created my first project (i am a Java developer for many years now, so i really have only problems with Android specific things).
And i already have my first problem and i have not enough knowledge to find the tutorials that i need for this or maybe i am just doing something wrong.
I have a main.xml file and a logon.xml file for the 2 different views (or how ever you call that) i need...i like to switch to logon.xml if i tap a button on main.xml. That works very well (i am using setContentView(R.layout.logon) so far but i am missing the animation between the two UIs...and so far none of the tutorials i have found are working with my scenario...can someone help me out?

I am a newbie in android dev.
I want to develop a very small and simple discount rate calculator.
in which there will be drop down menu with options like:
calculate 10%
calculate 20%
calculate 30%
Based on the selection of option from the drop down menu the discount rate should change.
After selection, there will be a textbox which should ask user to enter price.
and on the click even of "Calculate" button, the resultant amount (discounted rate) should be displayed.
I guess it is very simple for you guys. If anyone can help me with the code, i will deeply appreciate.
thank you
ok this is what I have done till now:
I created an Android Project names as :MyDC
MyDC.java
Code:
package com.super.mydc;
import android.app.Activity;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Button;
import android.view.View;
public class MyDC extends Activity {
private EditText amount1;
private double x=0;
private double y=2.0;
private double z=0;
private TextView tt;
private Button calculate;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
// We want to view some very simple text, so we need a TextView
TextView tv = new TextView(this);
// Put some text to the newly created TextVIew
tv.setText("Test");
// Tell our Application to display the textView
this.setContentView(tv);
super.onCreate(icicle);
setContentView(R.layout.main);
initControls();
}
private void initControls()
{
amount1=(EditText)findViewById(R.id.amount1);
tt=(TextView)findViewById(R.id.tt);
calculate=(Button)findViewById(R.id.calculate);
calculate.setOnClickListener(new Button.OnClickListener()
{public void onClick
(View v) { calculate();}});
}
private void calculate()
{
x=Double.parseDouble(amount1.getText().toString());
z=x-(x*y/100);
tt.setText(Double.toString(z));
}
}
This is main.xml

I am able to calculate discount on the button click, BUT i have hardcoded the discount rate.
I want to select discount rate based on the dropdown menu (I don't know how to set dropdown values with different discount rate in this problem)
In the dropdown menu I would like to have values like this:
Type 1 discount
Type 2 discount
Type 3 discount
Here is the respective discount rate for the above drop-down values:
Type 1 discount - 10%
Type 2 discount - 15%
Type 3 discount - 18%

Anyone ? Please Help ?
Im sorry to not be of very much help I studied java as a highschool unfortunately it was senior year and I am good at slacking. I would like to add suggestions though. first off i would try to find someway of implementing a way to get closer increments such as 5 or 1 %. such as a text box. let me sift through your code and see what i can see. are you having specific errors or what. we need some info.
Ok i looked at your code and im having a hard time reading it just because it isnt the norm that I look at. first off ya need to name your variables more recognizable things then x and y. that will make coding immensely more easy. also I am not seeing where you gathered the information from the drop down or spinner. at some point in the code you have to collect the information from the drop down or spinner and use it for the percent. also i didn't see any point where you gave the drop down any values. if you have any questions or anything feel free to pm I have xda app on my phone so even if not im not online ill get a notification on my phone.

Hi,
Yes, I know I haven't defined values to drop down because that is the thing I need help with.
I also posted above this:
"Now the question is how to select discount rate based on selected value from spinner.

I need help - How to define discount rate based on selection of drop down values.
Please help me with the code....
I also tried doing this quite awhile with an app I was writing and then discovered I had not enough experience to with the android system to write the program I should look it up and fix both of our programs but I've had a migraine for days and I'm just getting close to sleeping but when I get a chance I will look up giving values to the drop down and collecting them unless you want to google it first.

I have tried to find the solution on google but didn't get anything but somehow from google I was able to do (whatever I did above)
thanks, I think that would be great, if you can test my program on your side by that we both will be on the same page.
That's fine, you can test it whenever you get some time.
I appreciate your help!
I would setup radio buttons for the discount percentages
0 10% 0 20% etc.
Name each radio button and use a case statement to set a float to it's value:
switch(radioGroupName) {
case 10Percent:
int discountValue = .10
break;
...
Then do something like:
int discountedAmount = usersAmount - (usersAmount * discountValue);
Try this code.

Re: Need Help
Hello nemoc 23 ,
Firstly thank you very much for replying back with a solution.
It did work and solved my problem upto some extend.
Now what I only want 2 things to be done:
1) Right now, if we enter price in decimal or anything, if the final result is in decimal, it is being displayed as EXACT something like 99.9999999
How to limit the RESULT upto 2 decimal points only ?
2) What I am trying to do is to have this calculator on 3 different pages (in each page I will just modify the discounted rate). So I want a homepage (which will work as MENU) with 3 or 4 buttons and each button should be connected with specific page that will have ITS OWN above discount calculator.
Could you please show me how to create a homepage screen (which will work as MENU) and 3 or 4 buttons on it which are linked with different pages (in each page you can copy the same above calculator and I will modify the rate by myself)
thank you
Why 3 pages? Just do this:
Enter discount amount: ___________
Enter discount rate:______
Discounted Amount: ___________
Easy peasy.

Hello nemoc 23 ,
Just giving you an update. I did try the tutorial you asked me to try. I am having some problem in it which you can see here: http://forum.xda-developers.com/showthread.php?p=15612542
Coming back my question (this calculator topic) - I created a screen layout to give you an idea what I want to do and need your help with.
This is what I want to do:
In this each button click will open separate page (or I guess it is called activity). I have mentioned on button what each button will open.
Please help me. thanks
Intent i = new Intent(this, calculator1.class);
startActivity(i);
You are still better off creating just ONE new Activity and passing to it which calculator you want to run. It is poor programming to code 3 activities when one will suffice. You'll need "extras" to do this.

**Please help me!!!**
You got a couple options. First instead of the startActivity() throw in a Toast so you can see if your onClick() is ok. You can also throw some inline clicklisteners (anonymous inner class) inside the setOnClickListener() instead of using 'this'. I find that way is a bit easier to organize.
Annd might I suggest you follow the Java guidelines for capitalisation of class names. Its confusing when reading your code and seeing testcalculator.class when usually instances of objects are lower case while the class name is capitalized. Like TestCalculator.class

Hello,
is there a possibility to show the tabs from a TabHost next to each other, when the phone is in landscape-orientation?

I don't think there is. I haven't seen anyone do this yet, and it would only be confusing... Three tabs, two displayed at the same time is weird and takes away half the displayed content of one tab.
Anyhow, why use a TabHost? That's been deprecated for a long while, with the introduction of the ActionBar.

You can do that.
Have a look at Fragments. They are exactly what you want.
Just use a different layout for landscape.
pfuuu...that's too hard for me.
can you create a sample application which uses ActionBar-tabs in portrait and shows the content of the tabs in landscape-mode?

AB tabs can't show the content of multiple tabs at once, I think... Unless you do some intricate custom layout work, as nikwen said.

to expand on nikwen's answer what you need to do is have a layout file for listview and a layout file for portrait and landscape. To do the portrait and landscape you put the portrait file in the layout folder and create a layout-land folder. In the portrait file you would put one fragment and in the landscape file you would 5 (according to your image) fragments and you could put a textview above each if you are going to remove the tabs.
Action bar tabs are programmatically inserted so you would have to listen for orientation change and remove them when in landscape.
here are some resources that will help you:
Fragments:

Action Bar Tabs:

I have no rewritten my app and now its using action bar tabs and its creating a fragment 5 times with different data. How should i make the layout for landscape and how should i insert the fragments into the layout?
Thank you.
make a layout-land folder and create a custom layout for landscape

I have this custom listView:
<?xml version="1.0" encoding="utf-8"?>
<TableRow
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/tableRow">
<ImageView
android:id="@+id/img"

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textSize="25sp"
android:autoText="false"
android:gravity="center_vertical|center|center_horizontal" />
</TableRow>
This adapter:
public class CustomList extends ArrayAdapter<String> {
private final Activity context;
private final String[] title;
private final int[] colors;
private final Integer[] imageId;
public CustomList(Activity context,String[] title,int[] colors, Integer[] imageId) {
super(context, R.layout.list_single, title);
this.context = context;
this.title = title;
this.imageId = imageId;
this.colors=colors;
}
@override
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View rowView= inflater.inflate(R.layout.list_single, null, true);
TextView txtTitle = (TextView) rowView.findViewById(R.id.titleList);
ImageView imageView = (ImageView) rowView.findViewById(R.id.img);
txtTitle.setText(title[position]);
txtTitle.setTextColor(Color.parseColor("#FFffffff"));
txtTitle.setBackgroundColor(colors[position]);
imageView.setImageResource(imageId[position]);
return rowView;
}
}
and this is how I bind them:
final CustomList adapter = new
CustomList(MainActivity.this, title, colors, imageId);
list = (ListView) findViewById(R.id.list);
list.setAdapter(adapter);
My list has 12 items. I need to resize the list when user click one item. If the user choses an Item for the first time, the list has to change its width to 1/3 of its original size and to double the height of the selected item. If an item is already selected in the list and the user selects another the old item has to go back to the original height and the new selected one has to double its height without any width changes.
I want to animate all the resizing for nice looking.
This is the animation for changing width:
public class ShrinkList extends Animation
{
int fromWidth;
View view;
int def;
public ShrinkList(View view) {
this.view = view;
this.fromWidth = view.getWidth();
def=fromWidth/3;
}
@override
public boolean willChangeBounds() {
return true;
}
@override
public void initialize(int width, int height, int parentWidth,
int parentHeight) {
super.initialize(width, height, parentWidth, parentHeight);
}
@override
protected void applyTransformation(float interpolatedTime, Transformation t) {
int newWidth;
newWidth = (int) ((def - fromWidth) * interpolatedTime + fromWidth);
if (newWidth > def/3) {
view.getLayoutParams().width = newWidth;
view.requestLayout();
}
else{
view.getLayoutParams().width = def/3;
view.requestLayout();
}
}
}
and this one is for changing height:
public class Grow extends Animation
{
int fromHeight;
View view;
int defaultHeight;
public Grow(View view,int height) {
this.view = view;
this.fromHeight = view.getHeight();
defaultHeight=height;
}
@override
public boolean willChangeBounds() {
return true;
}
@override
public void initialize(int width, int height, int parentWidth,
int parentHeight) {
super.initialize(width, height, parentWidth, parentHeight);
}
@override
protected void applyTransformation(float interpolatedTime, Transformation t) {
int newHeight;
newHeight = (int) (fromHeight / (1 - interpolatedTime));
if (newHeight < defaultHeight * 2) {
view.getLayoutParams().height = newHeight;
view.requestLayout();
}
else{
view.getLayoutParams().height = defaultHeight*2;
view.requestLayout();
}
}
}
and I play them like that:
if(h==0) { //first time the user selects an item =>change width and height
Animation a = new ShrinkList(list);
a.setInterpolator(new LinearInterpolator());
a.setDuration(1000);
list.setAnimation(a);
list.startAnimation(a);
}
Animation a1 = new Grow(view,height); //change only height
a1.setInterpolator(new LinearInterpolator());
a1.setDuration(300);
view.setAnimation(a1);
view.startAnimation(a1);
My problem is that when the list changes its width, the animation is not smooth at all and it only changes the width, not the height too.
How can I make the animation smoother and make the two animations play at once?
I have tried scaling the list, but that scales all the list. basically I need only to resize the textView within ListView nd changing layoutParams does that.
I have tried to insert the code from Grow.java into ShrinkList.Java in orefer to play both animations once and it only played the one from Grow.java.

Do it like this
Code:
<RelativeLayout
android:id="@+id/myRelativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
[B]android:animateLayoutChanges="true"[/B]
<ListView
android:id="@+id/myListView"
android:layout_width="match_parent"
android:layout_height="match_parent"
[B]android:animateLayoutChanges="true"[/B]/>
</RelativeLayout>
Then you only need to change the width and height. And you don't have to worry about the animation

android:id="@+id/myRelativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
[B]android:animateLayoutChanges="true"[/B]
<ListView
android:id="@+id/myListView"
android:layout_width="match_parent"
android:layout_height="match_parent"
[B]android:animateLayoutChanges="true"[/B]/>
</RelativeLayout>
Then you only need to change the width and height. And you don't have to worry about the animation

I have tried what you suggested and the relative layout works great, but the list doesn't animate when it changes its witdh

You should add the animate layout changes to the first parent with match_parent as width

I created a relative layout as in your example and added animate layout changes to both the listview and that layout and changed the witth of the layout and it doesn't animate the list getting smaller. Only the next relative layout getting bigger after the list is small

Okey. AnimateLayoutChanges applies to the chields. So if you want to animate the relative layout the listview is in. You need to add animateLayoutChanges to his parent

I added animate layout changes to all the listView ancestors and it still doesn't animate the listView.
This is the java code for changing width. Maybe I doing something wrong here:
RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) linLay.getLayoutParams();
if(sdkVersion>=Build.VERSION_CODES.HONEYCOMB) {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
lp.width =size.x/3;
}
else{
Display display = getWindowManager().getDefaultDisplay();
lp.width = display.getWidth()/3;
}
linLay.setLayoutParams(lp); //linLay is the listView parrent and is a relativeLayout

You have to set the animateLayoutChanges to the paretn of linLay

Yes, I have already done that.As I said, I added animate layout changes to all of the listview ancestosr meaning linLay, parent of linLay, parent of parent of linLay and so on until the root of layouts, but the listView still doesn't animate
