RecyclerView的onClick [英] RecyclerView onClick

问题描述

具有使用 RecyclerView 找到了一种方法来设置 onClickListener 来的物品任何人 RecyclerView ？ 我想到了一个监听器设置每个布局的每个项目，但似乎有点太麻烦 我敢肯定有一种方法为 RecyclerView 来侦听的onClick 事件，但我不能完全数字出来。

Has anyone using RecyclerView found a way to set an onClickListener to items in the RecyclerView? I thought of setting a listener to each of the layouts for each item but that seems a little too much hassle I'm sure there is a way for the RecyclerView to listen for the onClick event but I can't quite figure it out.

推荐答案

请参阅雅各回答了更多的去耦解决方案，使用<一个href="https://developer.android.com/reference/android/support/v7/widget/RecyclerView.OnItemTouchListener.html">RecyclerView#OnItemTouchListener.

Please see Jacob's answer for a more decoupled solution, using RecyclerView#OnItemTouchListener.

随着API的从根本上改变，它不会让我感到吃惊，如果你要创建一个 OnClickListener 为每个项目。这是不是太大的麻烦，虽然。在你实施 RecyclerView.Adapter＆LT; MyViewHolder＆GT; ，你应该有：

As the API's have radically changed, It wouldn't surprise me if you were to create an OnClickListener for each item. It isn't that much of a hassle though. In your implementation of RecyclerView.Adapter<MyViewHolder>, you should have:

private final OnClickListener mOnClickListener = new MyOnClickListener();

@Override
public MyViewHolder onCreateViewHolder(final ViewGroup parent, final int position) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.myview, parent, false);
    view.setOnClickListener(mOnClickListener);
    return new MyViewHolder(view);
}

在的onClick 方法：

@Override
public void onClick(final View view) {
    int itemPosition = mRecyclerView.getChildPosition(view);
    String item = mList.get(itemPosition);
    Toast.makeText(mContext, item, Toast.LENGTH_LONG).show();
}

请注意，这仍然是在preVIEW，这样的API的可以的变化。

Note that this is still in preview, so API's may change.
