So I have created a spinner, placed it in my application, populated it and it works. I then went on to create a new class called MyOnItemSelectedListener. Here is that code:
Code:
import android.view.View;
import android.widget.AdapterView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemSelectedListener;
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public int i;
@Override
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
Toast.makeText(parent.getContext(), "You selected " +
parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();
i = (int)parent.getItemIdAtPosition(pos);
System.out.println(i);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
and here is my main class's code:
Code:
package de.vogella.android.temperature;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.Spinner;
import android.widget.Toast;
public class Convert extends Activity {
private EditText text;
private EditText answer;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
text = (EditText) findViewById(R.id.EditText01);
answer =(EditText) findViewById(R.id.EditText02);
//RadioButton celsiusButton = (RadioButton) findViewById(R.id.RadioButton01);
//RadioButton fahrenheitButton = (RadioButton) findViewById(R.id.RadioButton02);
/* if (fahrenheitButton.isChecked()) {
celsiusButton.setChecked(false);
} else if(celsiusButton.isChecked()){
fahrenheitButton.setChecked(false);
}
*/
Spinner s = (Spinner) findViewById(R.id.spinner);
ArrayAdapter adapter = ArrayAdapter.createFromResource(
this, R.array.type, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s.setAdapter(adapter);
}
// This method is called at button click because we assigned the name to the
// "On Click property" of the button
public void myClickHandler(View view) {
switch (view.getId()) {
case R.id.Button01:
//RadioButton celsiusButton = (RadioButton) findViewById(R.id.RadioButton01);
//RadioButton fahrenheitButton = (RadioButton) findViewById(R.id.RadioButton02);
if (text.getText().length() == 0) {
Toast.makeText(
this,
"Please enter a valid number", Toast.LENGTH_LONG).show();
return;
}
float inputValue = Float.parseFloat(text.getText().toString());
MyOnItemSelectedListener listener = new MyOnItemSelectedListener();
switch(listener.i){
case 0:answer.setText(String.valueOf(convertCelciusToFahrenheit(inputValue))+" Fahrenheit");
break;
case 1:answer.setText(String.valueOf(convertFahrenheitToCelcius(inputValue))+" Celcius");
break;
case 2:answer.setText(String.valueOf(centimetersToFeet(inputValue))+" Feet");
break;
case 3:answer.setText(String.valueOf(centimetersToInches(inputValue))+" Inches ");
break;
case 4:answer.setText(String.valueOf(centimetersToMiles(inputValue))+" Miles");
break;
case 5:answer.setText(String.valueOf(cmToDecimeter(inputValue))+" Decimeters");
break;
case 6:answer.setText(String.valueOf(cmToMm(inputValue))+" Milimeters");
break;
case 7:answer.setText(String.valueOf(cToK(inputValue))+" Kelvin");
break;
case 8:answer.setText(String.valueOf(DecimetertoCm(inputValue))+" Centimeters");
break;
case 9:answer.setText(String.valueOf(decimeterToMeters(inputValue))+" Meters");
break;
case 10:answer.setText(String.valueOf(dekametersToHectometers(inputValue))+" Hectometers");
break;
case 11:answer.setText(String.valueOf(dekametersToMeters(inputValue))+" Meters");
break;
case 12:answer.setText(String.valueOf(FeetToCentimeters(inputValue))+" Centimeters");
break;
}
break;
}
}
//MORE METHODS DOWN HERE JUST DIDNT COPY AND PASTE THEM FOR SIZE SAKE.
Now at the logic part (Case 1:, Case 2: etc. etc.) something is wrong. It always does case 0 and I cant figure out why. Im sure its something stupid on my part but I cant seem to find it. Is there a different way of determining what to do based on what is selected in the spinner?
Hi all!
I've been developing an app that uses various things from my college and centralizes them in one app. I've made the app with two tabs - one for current students and one for prospective students. I would like to add the functionality of swiping between the two activities, and I saw that to do that, I want to convert my currentStudents and prospectiveStudents activities into fragments.
I have a couple of questions.
First, I don't quite understand how to accomplish converting the activities into fragments.
Second, I don't quite understand how to implement the viewPager effect.
If anyone can assist me in doing this, that'd be great. I've read through a lot of guides, but those guides are written to reflect other apps and it's pretty confusing.
Here is my MainActivity:
Code:
package com.andrew.obu;
import android.app.TabActivity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.OnTabChangeListener;
import android.widget.TabHost.TabSpec;
public class MainActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabHost tabHost = getTabHost();
TabSpec cstudents = tabHost.newTabSpec("Current Students");
cstudents.setIndicator("Students");
Intent cstudentsIntent = new Intent(this, CurrentStudents.class);
cstudents.setContent(cstudentsIntent);
TabSpec prospects = tabHost.newTabSpec("Prospectives");
prospects.setIndicator("Prospectives");
Intent prospectsIntent = new Intent(this, ProspectiveStudents.class);
prospects.setContent(prospectsIntent);
tabHost.addTab(cstudents);
tabHost.addTab(prospects);
tabHost.getTabWidget().getChildAt(0).setBackgroundColor(Color.BLACK);
tabHost.getTabWidget().getChildAt(1).setBackgroundColor(Color.BLACK);
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
@Override
public void onTabChanged(String arg0) {
TabHost tabHost = getTabHost();
setTabColor(tabHost);
}
});
setTabColor(tabHost);
}
public void setTabColor(TabHost tabhost) {
for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.BLACK); //unselected
if(tabhost.getCurrentTab()==0)
tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.rgb(34, 34, 34)); //1st tab selected
else
tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.rgb(34, 34, 34)); //2nd tab selected
}
}

I recommend you to use ActionBarSherlock library: http://actionbarsherlock.com
Take a look at the samples and it will be easy to do what you ask for. At first, it may take a while to learn how to use this library, but you will not regret it since you will use it several times in the future for sure.
The coolest thing about this library is that it is compatible with older Android versions. I.e. The swipe effect will be available for Ice Cream users while for Froyo users will see two clickable tabs :good:
First of all, you can't swipe between activities. You can only swipe between fragments. Think of the activity as a container which holds your two fragments.
This is an example of a ListFragment:
Code:
public static class TitlesFragment extends ListFragment {
boolean mDualPane;
int mCurCheckPosition = 0;
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Populate list with our static array of titles.
setListAdapter(new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_activated_1, Shakespeare.TITLES));
// Check to see if we have a frame in which to embed the details
// fragment directly in the containing UI.
View detailsFrame = getActivity().findViewById(R.id.details);
mDualPane = detailsFrame != null && detailsFrame.getVisibility() == View.VISIBLE;
if (savedInstanceState != null) {
// Restore last state for checked position.
mCurCheckPosition = savedInstanceState.getInt("curChoice", 0);
}
if (mDualPane) {
// In dual-pane mode, the list view highlights the selected item.
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
// Make sure our UI is in the correct state.
showDetails(mCurCheckPosition);
}
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("curChoice", mCurCheckPosition);
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
showDetails(position);
}
/**
* Helper function to show the details of a selected item, either by
* displaying a fragment in-place in the current UI, or starting a
* whole new activity in which it is displayed.
*/
void showDetails(int index) {
mCurCheckPosition = index;
if (mDualPane) {
// We can display everything in-place with fragments, so update
// the list to highlight the selected item and show the data.
getListView().setItemChecked(index, true);
// Check what fragment is currently shown, replace if needed.
DetailsFragment details = (DetailsFragment)
getFragmentManager().findFragmentById(R.id.details);
if (details == null || details.getShownIndex() != index) {
// Make new fragment to show this selection.
details = DetailsFragment.newInstance(index);
// Execute a transaction, replacing any existing fragment
// with this one inside the frame.
FragmentTransaction ft = getFragmentManager().beginTransaction();
if (index == 0) {
ft.replace(R.id.details, details);
} else {
ft.replace(R.id.a_item, details);
}
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();
}
} else {
// Otherwise we need to launch a new activity to display
// the dialog fragment with selected text.
Intent intent = new Intent();
intent.setClass(getActivity(), DetailsActivity.class);
intent.putExtra("index", index);
startActivity(intent);
}
}
}
I can't help you there because I've never worked with lists.
As for the swiping effect, build your project with a minimum SDK of 14 (ICS) and choose swipe-able tabs navigation. The ADT will do the job for you. Later, in order to maintain compatibility, use ABS library as patedit suggested.
Good luck
To implement a ViewPager, just add ViewPager to XML layout, and set a FragmentPageAdapter to it.
You must use support package from Android SDK and FragmentActivity instead of Activitiy.
You can examine source code of API Demos package to know more.
I am making an android app which requires to capture image using front camera using android service. Also we need to detect face in the image so obtained.

Hi all,
I had an app that was working about 3 years ago that I decided to update for the latest android sdk.I was using tabs but have decided to update to tab fragments with swipe.The problem I'm having is how to lay out the code.I have updated my app but have a few errors.Specifically the Book Now tab usually has a book now form so people can fill it out and upon clicking submit it sms's it to me.Below is the code for BookNowFragmnet.java.
I should mention that the tab and swipe part works flawlessly.I dont have a logcat because it wont build without removing the code

So you are asking for the method "getBaseContext" within an onClickListener... it does not have a method called that... like it's telling you it's undefined
It would probably be a better idea to use application context either by direct use of getApplicationContext or by a "final" reference maybe...

BookNowFragment is not extended from the base type of Context that is expected in the arguments.

Actually the last to are just repeats of the previous really... I'm guessing here but it seems you may have skipped ahead of where you should be in a learning sense.. cause it seems to be like your running without being knowing how to jog kinda thing. Not attempting to be condescending, just I'm a trainer and always attempt to point this stuff out when I see it
Maybe go back and do some of the basics again, and include fragments etc
thanks, Im well aware i'm running before im born but this is the only app I intend to write as it's specifically for my business.

hmmm, well if thats all thats wrong with it, all I could offer is for you to send me the packaged src+res and I will have a look... if it takes less than 20 min to fix and get running I have no problem fixing it for you. If it doesn't and maybe takes longer then I may have to leave it. Should be quick though, up to you
But with the info I gave you should be able to fix those 4 issues...if not hit me up on hangouts and will talk you though it
thanks m8.Ill play around today but if I cant figure it out I might get you to have a look if time permits.I develop in eclipse.Is it a matter of just zipping up the project folder?

Yeah, just zip the project.
But like I say just get a reference to the activity to use as the "context" part of the argument, either where you need it or as a final reference or member variable
so getActivity()
or memberVar
Context mContext = null;
(in onCreate) mContext = getActivity();
or as final
final Context c = getActivity();

I forgot the date and time picker arrrrrrrgh
I've added the following 2 classes which have no errors and seem to function fine.
DatePickerFragment.java
PHP:
package com.test.dfw;
import java.util.Calendar;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;

import android.widget.TextView;
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
TextView txtDate;
public DatePickerFragment(TextView txtDate) {
super();
this.txtDate = txtDate;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
txtDate.setText(new StringBuilder().append(month + 1)
.append("-").append(day).append("-").append(year)
.append(" "));
}
}
TimePickerFragment.java
PHP:
package com.test.dfw;
import java.util.Calendar;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.text.format.DateFormat;
import android.widget.TextView;
import android.widget.TimePicker;
public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener{
TextView txtTime;
public TimePickerFragment(TextView txtTime) {
super();
this.txtTime = txtTime;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current time as the default values for the picker
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(getActivity(), this, hour, minute,
DateFormat.is24HourFormat(getActivity()));

The problem areas are all under BookNowFragment.java;
1. Under "showCurrentDateOnView" the both findViewById says undefined for the type.I have tried adding rootView but didnt work.
2. Under "showCurrentTimeOnView" both findViewById says undefined for the type.I have tried adding rootView but didnt work.
3. under "showDatePickerDialog" and "showTimePickerDialog" both the getSupportFragmentManager methods show the error "The method getSupportFragmentManager() is undefined for the type BookNowFragment"
4. I also have errors with "onCreateOptionsMenu".I worked out some of them by adding getActivity (see new code below) but it still shows the error "The method onCreateOptionsMenu(Menu) of type BookNowFragment must override or implement a supertype method"
PHP:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getActivity().getMenuInflater().inflate(R.menu.main, menu);
return true;
}
Think there simple issues although I'm simple as well so I could be understating it.
