推荐答案

由于v22.2.0，Android的支持团队包括了一个 ItemTouchHelper 类，使刷卡到-dismiss并拖动和拖放pretty的简单。这可能不是作为全功能的，因为一些图书馆在那里，但它是直接从Android团队。

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.

+的RecyclerView库

• 更​​新您的build.gradle进口v22.2。

• Update your build.gradle to import v22.2.+ of the RecyclerView library

compile 'com.android.support:recyclerview-v7:22.2.+'

实例化一个合适的SimpleCallback的ItemTouchHelper

Instantiate an ItemTouchHelper with an appropriate SimpleCallback

ItemTouchHelper.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);

**注意SimpleCallback需要在要启用拖和下降的方向，并且要启用刷卡方向。

** Note that the SimpleCallback takes in the directions that you want to enable drag-and-drop and the directions that you want to enable swiping.

附加到您的RecyclerView

Attach to your RecyclerView

itemTouchHelper.attachToRecyclerView(recyclerView);
