Detect XY-coordinates when clicking or touching on screen

If you want to get the XY-coordinates when users click on screen, the implementation of OnClickListener won’t do it. However, you need to override the onTouchEvent(), this will do the trick.

package pete.android.study;

import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.Toast;

public class MainActivity extends Activity  {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

	@Override
	public boolean onTouchEvent(MotionEvent event) {
		// MotionEvent object holds X-Y values
		if(event.getAction() == MotionEvent.ACTION_DOWN) {
			String text = "You click at x = " + event.getX() + " and y = " + event.getY();
			Toast.makeText(this, text, Toast.LENGTH_LONG).show();
		}

		return super.onTouchEvent(event);
	}
}

Hope you enjoy it!

Cheers,
