How to listen to doubletap on a view in android? [duplicate]
I want to detect a doubletap
on a view, like for example a button
, and then know which view it was. I have seen this similar question but the question they say it is a duplicate of it does not seem to answer my question.
All I can find is to add a GestureDetector
to the activity, and add a OnDoubleTapListener
to it. But that is only triggered if I tap on the background/layout of my screen. It is not triggered when I (double)tap a button
.
This is the code I have inside my onCreate
:
gd = new GestureDetector(this, this);
gd.setOnDoubleTapListener(new OnDoubleTapListener()
{
@Override
public boolean onDoubleTap(MotionEvent e)
{
Log.d("OnDoubleTapListener", "onDoubleTap");
return false;
}
@Override
public boolean onDoubleTapEvent(MotionEvent e)
{
Log.d("OnDoubleTapListener", "onDoubleTapEvent");
//if the second tap hadn't been released and it's being moved
if(e.getAction() == MotionEvent.ACTION_MOVE)
{
}
else if(e.getAction() == MotionEvent.ACTION_UP)//user released the screen
{
}
return false;
}
@Override
public boolean onSingleTapConfirmed(MotionEvent e)
{
Log.d("OnDoubleTapListener", "onSingleTapConfirmed");
return false;
}
});
Solution 1:
You can achieve this by just using these few lines of codes. It's that simple.
final GestureDetector gd = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener(){
//here is the method for double tap
@Override
public boolean onDoubleTap(MotionEvent e) {
//your action here for double tap e.g.
//Log.d("OnDoubleTapListener", "onDoubleTap");
return true;
}
@Override
public void onLongPress(MotionEvent e) {
super.onLongPress(e);
}
@Override
public boolean onDoubleTapEvent(MotionEvent e) {
return true;
}
@Override
public boolean onDown(MotionEvent e) {
return true;
}
});
//here yourView is the View on which you want to set the double tap action
yourView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
return gd.onTouchEvent(event);
}
});
Put this piece of code on the activity or adapter where you want to set the double tap action on your view.
