android - SwipeRefreshLayout 阻止水平滚动的 RecyclerView

Question

我的设置很简单:

<android.support.v4.widget.SwipeRefreshLayout
     android:id="@+id/swiperefresh"
     android:layout_width="match_parent"
     android:layout_height="match_parent" >

     <android.support.v7.widget.RecyclerView
         android:id="@+id/recyclerView"
         android:layout_width="match_parent"
         android:layout_height="220dp"/>

</android.support.v4.widget.SwipeRefreshLayout>

onCreate()的内容:

layoutManager = new LinearLayoutManager( this );
layoutManager.setOrientation( LinearLayoutManager.HORIZONTAL );
topTopicRecyclerView.setLayoutManager( layoutManager );

现在，当我向左或向右滑动 recyclerView 并且滑动角度不是完全水平时，SwipeRefreshLayout 会跳入并接管滚动控件。这会导致 recyclerView 内部出现恼人的视觉“打嗝”。

如果 SwipeRefreshLayout 被禁用，一切都很好。

那么，如何才能停用 SwipeRefreshLayout 对 RecyclerView 区域的滚动控制？

Answer 1

根据 this discussion about SRL and HorizontalScrollView ，我为 SwipeRefreshLayout 创建了副本:

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 );
  }
}

以及在 XML 中的用法:

<com.commons.android.OnlyVerticalSwipeRefreshLayout
     android:id="@+id/swiperefresh"
     android:layout_width="match_parent"
     android:layout_height="match_parent" >
