在第一个cell recyclerview中检测水平过度滚动并显示删除选项

Question

我想在第一个单元格中显示删除选项，在水平回收视图的滚动滚动上，如在垂直列表视图中，可以选择删除或向左或向右滑动项目上的其他选项。有什么例子我能实现吗？

检查此链接，您可能会得到解决方案， https://github.com/daimajia/AndroidSwipeLayout

As of v22.2.0, the Android support team has included an ItemTouchHelper class that makes swipe-to-dismiss and drag-and-drop pretty simple. This may not be as full-featured as some of the libraries out there, but it comes directly from the Android team.

1）更新build.gradle以导入RecyclerView库的v22.2。+

compile 'com.android.support:recyclerview-v7:22.2.+' 2）使用适当的

实例化ItemTouchHelper

SimpleCallbackItemTouchHelper.SimpleCallback simpleItemTouchCallback = new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) { 
    [...]
    @Override
    public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
        //Remove swiped item from list and notify the RecyclerView
    } 
}; 
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(simpleItemTouchCallback)

请注意，SimpleCallback会引导您要启用拖放的路线以及要启用滑动的路线。

3）附加到RecyclerViewitemTouchHelper.attachToRecyclerView（recyclerView）;
