Scrollview doesn't swipe when it's too short to scroll

Question

I\'m pretty new to Android app development, and I\'ve been playing around with swipe gestures using Android\'s SimpleOnGestureListener and a ViewFlipper. There are 3 childr

Answer 1

Try setting android:fillViewport="true" in your layout xml for each of the ScrollViews. That tells the ScrollView to be as large as the view it's contained in.

Answer 2

Had the same issue. You need to intercept the touch event on the children of the ScrollView when it's too short to have a scrollbar.

Answer 3

I needed to create a new class that extended ScrollView, and used this:

@Override
public boolean onTouchEvent(MotionEvent event) {
    super.onTouchEvent(event);
    return gestureDetector.onTouchEvent(event);
}

@Override 
public boolean dispatchTouchEvent(MotionEvent ev){
    gestureDetector.onTouchEvent(ev);
    super.dispatchTouchEvent(ev); 
    return true;
} 

I have no idea why, but if I try to return anything but true in dispatchTouchEvent (the logical thing would have been to

return (gestureDetector.onTouchEvent(ev) || super.dispatchTouchEvent(ev)); 

if I understand properly), it doesn't work, and this does.
