Java – Double-click textview android

I

want to double-click on the textview because I used the code below

But still not 🙁

TextView txtOne;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

txtOne = (TextView) findViewById(R.id.txtOne);
    txtOne.setOnTouchListener(new View.OnTouchListener() {

@Override
        public boolean onTouch(View v, MotionEvent event) {
            System.out.println("DRAG");
            return gestureDetector.onTouchEvent(event);

}
    });
}

final GestureDetector gestureDetector = new GestureDetector(
        new GestureDetector.SimpleOnGestureListener() {

@Override
            public boolean onDoubleTap(MotionEvent e) {
                System.out.println("Double Tap");
                return super.onDoubleTap(e);
            }

@Override
            public boolean onSingleTapUp(MotionEvent e) {
                System.out.println("One Click");
                return super.onSingleTapUp(e);
            }

});

Only drag invokes, but not double-click and click

Try the following steps.

Step 1

Write the following code in your activity.

// initialize the Gesture Detector
gd = new GestureDetector(this,new OnGestureListener() {
    @Override
    public boolean onSingleTapUp(MotionEvent e) {
         TODO Auto-generated method stub
        return false;
    }

@Override
    public void onShowPress(MotionEvent e) {
         TODO Auto-generated method stub

}

@Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
            float distanceY) {
         TODO Auto-generated method stub
        return false;
    }

@Override
    public void onLongPress(MotionEvent e) {
         TODO Auto-generated method stub

}

@Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {
         TODO Auto-generated method stub
        return false;
    }

@Override
    public boolean onDown(MotionEvent e) {
         TODO Auto-generated method stub
        return false;
    }
});

 set the on Double tap listener
gd.setOnDoubleTapListener(new OnDoubleTapListener() {
    @Override
    public boolean onDoubleTap(MotionEvent e) {
        Toast.makeText(SplashActivity.this,"Double Tap",Toast.LENGTH_LONG).show();
    return false;
    }

@Override
    public boolean onDoubleTapEvent(MotionEvent e) {
         if the second tap hadn't been released and it's being moved

return false;
    }

@Override
    public boolean onSingleTapConfirmed(MotionEvent e) {
         TODO Auto-generated method stub
        return false;
    }

});

Step two

Write the following code for the activity. Here gd will be the GestureDetector object.

txt.setOnTouchListener(new View.OnTouchListener() {

@Override
        public boolean onTouch(View v, MotionEvent event) {
             TODO Auto-generated method stub
            gd.onTouchEvent(event);
            return false;
        }
    });
