Question

I have an activity in which I have an ImageView and a SeekBar. I registered a listener with imageview1.setOnTouchListener(mylistener) for the ImageView(mylistner is a class). I get the motion events in onTouch method in my listener. I want the program to hide the SeekBar when I touch the Image View. All the Tutorials I watched show how the listener gets the event from the source. But what I am looking for is sending the data back to the source, so that it can hide the SeekBar.

The main question is in touch event handling of an activity how we can get results back from the listener class to the calling class(source)? Is there a better way to do what I want?

should I make another event which will call for the SeekBar? if yes How?

public class A extends Activity {
//.....
final SeekBar sb=(SeekBar) findViewById(R.id.seekBar1);
Mylistener mylistener;
mylisetner=new MyListener(getApplicationContext());

ImageView.setOnTouchListener(mylistener);
//.....

}

public class MyListener implements View.OnTouchListener {
//.....

public boolean onTouch(View v, MotionEvent event) {
final int action = event.getAction() & MotionEvent.ACTION_MASK; 
switch (action) {
        case MotionEvent.ACTION_DOWN:          
       // here how can you get access to the seek bar? or how you inform it to hide?
}
//....

}

From what i understood from your question, you want to hide the seekbar when imageview is touched.. right?

try following code in your ontouchlistener….

public boolean onTouch(View v, MotionEvent event) {  
 if (event.getAction() == MotionEvent.ACTION_UP){
     seekbar.setVisibility(View.VISIBLE);
 } else if (event.getAction() == MotionEvent.ACTION_DOWN) {
     seekbar.setVisibility(View.GONE);
 }
}

where seekbar is your SEEKBAR :), hold its reference in oncreate…..
