android – java.lang.IllegalArgumentException: pointerIndex out of range Exception – dispatchTouchEvent

Questions:

I have this method in my custom view which extends FrameLayout:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    int currentItem = vp.getCurrentItem();
    if (inDragPanelZone(currentItem, ev.getX(), ev.getY()) && ev.getAction() == MotionEvent.ACTION_DOWN) {      
        if (!shouldAllowPaging()) { 
            return true; 
        }
        vp.setPagingEnabled(true);
    }
    return super.dispatchTouchEvent(ev);
}

Once in a while – I’m getting the following Exception:

I also tried using onInterceptTouchEvent() and got the same exception.

Here is an additional stacktrace:

How to&Answers:

There is a bug in 2.1 (Eclair) where the pointer index isn’t checked and is sometimes -1. You can create a custom view that extends ViewPager, override onTouchEvent and wrap the call to super.onTouchEvent in a try/catch. Whilst not a very pretty fix, I remember that it has no side effects (like missed touch events).

Answer:

Adding to the above answer Also you can try Overriding onInterceptTouchEvent method and surround super.onInterceptTouchEvent(ev) with try and catch worked for me in a ViewPager

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    try {
        return super.onInterceptTouchEvent(ev);
    } catch (IllegalArgumentException ex) {
        ex.printStackTrace();
    }
    return false;
}

Answer:

I had the same problem and I created a custom ViewPager to catch the exception. Here is the solution in kotlin:

class CustomViewPager : ViewPager {

    constructor(context: Context) : super(context)

    constructor(context: Context, attrs: AttributeSet?) : super(context, attrs)

    override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean =
        try {
            super.onInterceptTouchEvent(ev)
        } catch (e: IllegalArgumentException) {
            //uncomment if you really want to see these errors
            //e.printStackTrace();
            false
        }
}
