You can get the on touch event and see if Action down, Move or Action Up and other actions but for the moment let us stop here. I have a simple example that I think you or anyone else will find it usefull.
import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.Toast;
public class MainActivity extends Activity {
private boolean isTouch = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
int X = (int) event.getX();
int Y = (int) event.getY();
int eventaction = event.getAction();
switch (eventaction) {
case MotionEvent.ACTION_DOWN:
Toast.makeText(this, "ACTION_DOWN AT COORDS "+"X: "+X+" Y: "+Y, Toast.LENGTH_SHORT).show();
isTouch = true;
break;
case MotionEvent.ACTION_MOVE:
Toast.makeText(this, "MOVE "+"X: "+X+" Y: "+Y, Toast.LENGTH_SHORT).show();
break;
case MotionEvent.ACTION_UP:
Toast.makeText(this, "ACTION_UP "+"X: "+X+" Y: "+Y, Toast.LENGTH_SHORT).show();
break;
}
return true;
}
}
