TextView Into and Integer

I am trying to pass information from a text view into an ImageView to move the ImageView. The problem is I can't use the TextView information because it is defined as a TextView. So is there a way I can get it to use the TextView as an integer?

Do you mean you want to convert the text string in the textview to an integer? There's the java.lang.Integer class which has a static member parseInt() which might do what you need:
http://developer.android.com/reference/java/lang/Integer.html#parseInt(java.lang.String)

Not completely sure what your looking for but if I read it right,
imageView.setMethod(parseInt(textView.getText()))
setMethod being which ever method your trying to set the int into.

I need the data from my accelerometer code which looks like so:
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();
}
}

I need to put that into my imageview and use scrollby to move the imageview around the screen.

I'm not too familiar with imageviews, are you using XMLs for the layout or creating the imageViews programmaticly? I'm assuming the textViews and imageViews are in seperate classes. Thus the easiest way to get the text from the textViews would be to first give them the "protected" token rather than "private" and reference them directly.
Code:
imageView.scrollBy(parseInt(TestActivity.accelXValue.getText()));

I have tried that before but no matter what I try I get an error. Here is the error:
Cannot make a static reference to the non-static field TestActivity.accelXValue

So then I change it to static and get the following error:
The method parseInt(CharSequence) is undefined for the type TestActivity

I can't seem to get something that seems so simple to work.

last tempt at asking for help

Ok all i have tried for weeks now to get a simple webview app sorted. i have managed to get this up on the market but it needs a few more features like menu for refresh back forward etc.
It seems nobody really wants to helps so how much will it cost me for you to help with it?

explain a little more, you after someone to code it for you or design the ui ?

Well basically I got a basic webview made from tutorials, but that is about as far as my skills go. I need a few more features like options menu, stop the back button exiting app and go back a page instead and also if possible but not essential change loading bar for loading circle which spins in middle if screen while loading. I have tried to ask for help with what code I need and where to put it but no luck. I pretty much need it coded or at least to be told what code and exactly where in my code I need to fit it in.

Where have you tried asking? Tackle one issue at a time, and post some example code.
StackOverflow is a great site for programming questions and you should get some good answers there.
But before posting make sure you search first.
The back button shouldnt exit the app if there is a activity that was displayed before it.

I found this tutorial after a quick google search - http://kahdev.wordpress.com/2008/11/25/building-a-menu-for-your-android-v10-r1-app/
It seems quite simple to follow. Let me know if you have any issues and I try give you an example for your code tonight.

Ok I have edited your code to add a menu, and also to set the back button of the phone to go back to the previous page in the webview, instead of previous activity.
I found the code for this here
I have commented bits of the code so hopefully its understandable.
If you have any questions or it doesn't work let me know.
Don't just take what I have done and use it (although you can). Go through it and make sure you understand what I have done. That's the only way you will learn app development.
Code:
package com.windowcleaningforums;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class windowcleaningforums extends Activity {
final Activity activity = this;
//DECLARE webview variable outside of onCreate function so we can access it in other functions (menu)
public WebView webView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
webView = (WebView) findViewById(R.id.WebView);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
activity.setTitle(" Loading...");
activity.setProgress(progress * 100);
if (progress == 100)
activity.setTitle(R.string.app_name);
}
});
webView.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
// Handle the error
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webView.loadUrl("http://www.windowcleaningforums.co.uk");
}

super.onCreateOptionsMenu(menu);
//Add menu items, second value is the id, use this in the onOptionsItemSelected
menu.add(0,1, 0, "Back");
menu.add(0, 2, 0, "Forward");
return true;
}
@Override
public boolean onOptionsItemSelected (MenuItem item){
switch (item.getItemId()){
//If the ID equals 1 , go back
case 1:
webView.goBack();
return true;
//If the ID equals 2 , go forward
case 2 :
webView.goForward();
return true;
}
return false;
}

if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) {
webView.goBack();

}
return super.onKeyDown(keyCode, event);
}
}

I have seen these tutorials but my problem is I don't know how to fit it into my webview where should I add this in my code
Sent from my Desire HD using XDA App

Have a look at the code I posted.
What we are basically doing is adding new functions (or methods) inside our activity class. When I first started app development I also got confused as to where to add things.
These new methods override methods built into the activity, so we don't want to put them inside our onCreate method (where everything goes for setting up the activity, and where all your current code resides).
So we put them at any position after the closing brace of our onCreate. I've put them at the end.
I also moved the declaration of the webView variable to outside the onCreate method, so we can access it in the other functions we added.

Thank you so much I will look at this properly when I next get chance on my pc. thanks again for the help and taking the time to explain.

Thank you have have looked over the code and even added another button!
I have also added icons for each menu item after looking over some other code but not sure if i have done it correctly. they dont show untill the menu item has been clicked once. how can i get them to show right away? i put the images in res/drawable and called then in the code below, is this the correct way to do it?

As SilentMobius' comments pointout, you need to set your icons in the onCreateOptionsMenu, not the onOptionsItemSelected.
That's why they are only showing when you select the button.

Ah great thanks i figured it, didn't want to be given correct code just you giving the correct info to sort my self is good i know these are most likely simple things but nobody learns unless they ask questions thanks again.
Check my apps out in the market Luvdroid and window cleaning forums

Would you mind sharing your back, forward and refresh icons with me? I'm looking for something very clean and standardized for use on 12 webview apps for the some of the local municipalities.

[Q] Drawing a circle custom view centered with pinch zoom gesture

I'm trying to make a custom view that draw a circle in the center os this view (position always fixed) and I want to implement the scale of this circule use pinch gesture (I've used ScaleGestureDetector).
I managed to draw the circle in the center of the custom layout but I can not implement the functionality of scaling correctly using pinch gesture.
Please, can you give a hint please how I could do it?

The Fragment that should contain a Navigation Drawer is Resturants , also drawer's mainactivity is implemented with Sherlock Library(SherlockFragmentActivity).
I'm puzzled how to call the SherlockFragmentActivity from the SherlockActivity
Thanks

The Fragment that should contain a Navigation Drawer is Resturants , also drawer's mainactivity is implemented with Sherlock Library(SherlockFragmentActivity).
I'm puzzled how to call the SherlockFragmentActivity from the SherlockActivity
Thanks

That last sentence does not make sense I assume you mean from the Fragment?! Well to access the holding activity you need to add an interface to the Fragment which the activity will implement.
Am I understanding you correctly that have a horizontal ViewPager and one of the Fragments should have a Navigation drawer? To accomplish that you would still need the whole activity to hold the drawer and figure out a way to disable it when the user is on some other Fragment. But my question is why you want to use a navigation drawer in that case, because the drawer is meant for navigating on the same hierarchical level, but the different items are more independent than with the ViewPager. It doesn't really make sense to have both a drawer and horizontal swiping, even the YouTube app really bothers me with its swiping between suggestions and feed. I think what you need to use here is a spinner in the ActionBar, replacing the title of the Fragment.

Yeah you're right , I just want to use the drawer in order to change contents.
So as you suggest , I just have to use a simple tricks to make the drawer enable in desire Fragment.
I don't want to , I am asked to make it possible....

How to make the buttons in a fragment manipulate integer variables in seperate activi

This is a rudimentary android application that serves as an umpires strike/ball/out counter. There is a settings icon in the action bar of the MainActivity. When this icon is 'clicked on', a new Activity is started consisting of a PreferenceFragment, which consists of a checkboxpreference, and a Fragment that consists of 3 buttons. These buttons reset the stike_count, ball_count and total_outs_count to zero. I have spent a day on this and am having trouble figuring out how to manipulate integer variables in my MainActivity from button clicks in a seperate Activity's Fragment. Please point me in the right direction.

To modify anything in your activity from one of its child Fragments you would typically create an interface in the Fragment and have the activity implement that. That interface would either contain one method setting all three vars or multiple ones, one for each variable. To call the methods in the interface call getActivity() and typecast it to the interface.
