檢測水平overscroll和顯示刪除選項在第一個單元recyclerview

Question

我想顯示刪除選項與水平recyclerview的過度滾動第一個單元格，就像在垂直listview有選項刪除或其他選項上滑動項目向左或向右。有什麼例子可以實現嗎？

檢查這個環節你可能會得到解決， 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）更新您的build.gradle導入v22.2 +的RecyclerView庫

compile 'com.android.support:recyclerview-v7:22.2.+' 2）實例化的ItemTouchHelper與適當的

SimpleCallbackItemTouchHelper.SimpleCallback simpleItemTouchCallback = new ItemTouchHelper.SimpleCallback（0，ItemTouchHelper.LEFT | ItemT ouchHelper.RIGHT）{[...] @Override public void onSwiped（RecyclerView.ViewHolder viewHolder，int swipeDir）{//從列表中刪除滑動的項目並通知RecyclerView}}; ItemTouchHelper itemTouchHelper = new ItemTouchHelper（simpleItemTouchCallback）; **請注意，SimpleCallback接受您希望啓用拖放操作的指示以及您希望啓用滑動的指示。

3）附加到您的RecyclerViewitemTouchHelper.attachToRecyclerView（recyclerView）;
