Horizontalscrollview Within Scrollview Touch Handling

HorizontalScrollView within ScrollView Touch Handling

Update: I figured this out. On my ScrollView, I needed to override the onInterceptTouchEvent method to only intercept the touch event if the Y motion is > the X motion. It seems like the default behavior of a ScrollView is to intercept the touch event whenever there is ANY Y motion. So with the fix, the ScrollView will only intercept the event if the user is deliberately scrolling in the Y direction and in that case pass off the ACTION_CANCEL to the children.

Here is the code for my Scroll View class that contains the HorizontalScrollView:

public class CustomScrollView extends ScrollView {
    private GestureDetector mGestureDetector;

    public CustomScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
        mGestureDetector = new GestureDetector(context, new YScrollDetector());
        setFadingEdgeLength(0);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return super.onInterceptTouchEvent(ev) && mGestureDetector.onTouchEvent(ev);
    }

    // Return false if we're scrolling in the x direction  
    class YScrollDetector extends SimpleOnGestureListener {
        @Override
        public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {             
            return Math.abs(distanceY) > Math.abs(distanceX);
        }
    }
}

Android: HorizontalScrollView inside ScrollView

You can use Recycler view with Staggered layout manager

 StaggeredGridLayoutManager  staggeredGridLayoutManager = new StaggeredGridLayoutManager(4, StaggeredGridLayoutManager.HORIZONTAL);

 RecyclerViewAdapter recyclerViewAdapter = newRecyclerViewAdapter(this);

 recyclerView.setAdapter(recyclerViewAdapter); //Don't miss to initialize your adapter

Android HorizontalScrollView disable touch handling but allow child get events

i am not very clear regarding what you want to do but, this should work,

OnTouchListener skipTouchListener = new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            //do nothing
            return false;
        }
};
yourView.setOnTouchListener(skipTouchListener);

This way yourView will not process the touch events.

How to detect touch event at ScrollView?

As you've already mentioned in the question, onTouchEvent do have ACTION_UP that is meant to handle when touch up.
