SwipeRefreshLayout blocking horizontally scrolled RecyclerView

Question

My setup is simple enough:

Answer 1

As per this discussion about SRL and HorizontalScrollView, I created the counterpart for the SwipeRefreshLayout:

public class OnlyVerticalSwipeRefreshLayout extends SwipeRefreshLayout {

  private int touchSlop;
  private float prevX;
  private boolean declined;

  public OnlyVerticalSwipeRefreshLayout( Context context, AttributeSet attrs ) {
    super( context, attrs );
    touchSlop = ViewConfiguration.get( context ).getScaledTouchSlop();
  }

  @Override
  public boolean onInterceptTouchEvent( MotionEvent event ) {
    switch( event.getAction() ){
      case MotionEvent.ACTION_DOWN:
        prevX = MotionEvent.obtain( event ).getX();
        declined = false; // New action
        break;

      case MotionEvent.ACTION_MOVE:
        final float eventX = event.getX();
        float xDiff = Math.abs( eventX - prevX );
        if( declined || xDiff > touchSlop ){
          declined = true; // Memorize
          return false;
        }
        break;
    }
    return super.onInterceptTouchEvent( event );
  }
}
