Question

I want to know that if I have two activities in a program then how can I switch between two activities using ontouchlistener, just only touching anywhere on the screen?

public class V19 extends Activity implements OnTouchListener{

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.lay19);
    }

    @Override
    public boolean onTouch(View to_main, MotionEvent event) {
        return false;
    }
}

Answer 1

You can use layout inflater and method setContentView(View v)

public class V19 extends Activity implements OnTouchListener{

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    View view = getLayoutInflater().inflate(R.layout.lay19, null);
    setContentView(view);
    view.setOnTouchListener(this);
}

@Override
public boolean onTouch(View to_main, MotionEvent event) {
    Intent i = new Intent(this, Activity2.class);
    startActivity(i);
    return false;
}
}    

And than you can catch all touch events.

Other way is to override public boolean dispatchTouchEvent (MotionEvent ev) method. Reference says:

public boolean dispatchTouchEvent (MotionEvent ev)

Since: API Level 1
Called to process touch screen events. You can override this to intercept all touch screen events before they are dispatched to the window. Be sure to call this implementation for touch screen events that should be handled normally.
Parameters

ev The touch screen event.

Return true if this event was consumed.
