Very simple question today. When I attempt to retreive a reference to the button on the dialog I always receive a null value.
@Override
public void onRestart() {
super.onRestart();
//must prompt with modal dialog for pin
Dialog dialog = new Dialog(this);
dialog.setOwnerActivity(this);
dialog.setCancelable(false);
//check pin
dialog.setCanceledOnTouchOutside(false);
//set view to enterpin XML screen
dialog.setContentView(R.layout.enterpin);
//register button
//show dialog
dialog.show();
//listen for button being clicked
Button button = (Button) findViewById(R.id.pinlogin);
button.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v){
EditText editText = (EditText) findViewById(R.id.enterpin);
int enteredPin = Integer.parseInt(editText.getText().toString());
SharedPreferences sharedP = getPreferences(MODE_PRIVATE);
int temp = sharedP.getInt("pin", 0);
if(enteredPin==temp){
pinCheck = true;
}else{
pinCheck = false;
}
}
});
if(pinCheck){
dialog.dismiss();
}
}
Yes the button exists, no I did not mispell it's reference. Yes I've cleaned the project and restarted eclipse. How can the button not be associated with the view when i clearly called setContentView()? I'm sure it's simple, I've never used dialogs before, new to GUI in general. Especially Android
Button button = (Button)dialog.findViewById(R.id.pinlogin);
^^^^^^
When you show Dialog ,you have to give refrences of dialog
.because without it , Button refrences from main.xml
.i mean from main view setContentView(R.layout.main);
