OnTouchListener doesn't work with relative layout

In myRelativeLayout.xml add:

android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"

This worked for me:

yourRelativeLayout.setOnTouchListener(new View.OnTouchListener() {  
    @Override
    public boolean onTouch(View arg0, MotionEvent arg1) {
        //gesture detector to detect swipe.
        gestureDetector.onTouchEvent(arg1);
        return true;//always return true to consume event
    }
});

tv.setClickable(true);

is causing your layout, not to fire touch event. Try removing this.
