Hello, and I hope you are having fun learning! :)
I took your code and quickly cleaned it up for you. I didn't test it so I
don't know if anything i've done helped. BUT you had a lot of stuff in there
that I would be surprised if it even compiled. I wrote comments explaining
my changes...
Hope it helps
private AudioManager mAudioManager;
private boolean mPhoneIsSilent;
// Use something else besides a reserved word for naming your fields,
methods, classes, etc...
// Also you don't need this boolean. You can simply use 'false' or
'true'
// private boolean False;
/** Called when the activity is first created. */
@Override
public void onCreate( Bundle savedInstanceState ) {
super.onCreate( savedInstanceState );
setContentView( R.layout.main );
mAudioManager = (AudioManager)getSystemService( AUDIO_SERVICE );
checkIfPhoneIsSilent();
// You can wrap your listener with a method however, I find it is
better to init my
// listeners in the onStart method. See the Activity lifecycle
// Example below in the onStart() method...
// setButtonClickListner();
Log.d( "SilentModeApp", "This is a test" );
}
@Override
public void onStart() {
Button toggleButton = (Button)findViewById( R.id.toggleButton );
toggleButton.setOnClickListener( new View.OnClickListener() {
public void onClick( View v ) {
// Do some click stuff here...
}
} );
}
// I have no idea why this is here??? You perform the check in your
checkIfPhoneIsSilent()
// {if (mPhoneIsSilent)
// {
// mAudioManager
// .setRingerMode(AudioManager.RINGER_MODE_NORMAL);
//
// mPhoneIsSilent = False;
// }
// else
// {
// mAudioManager
// .setRingerMode(AudioManager.RINGER_MODE_SILENT);
// boolean True = false;
