RecyclerView onClick [英] RecyclerView onClick

问题描述

有没有人使用 RecyclerView 找到一种方法来设置 onClickListener 到 RecyclerView 中的项目?我想为每个项目的每个布局设置一个侦听器，但这似乎有点麻烦我确定 RecyclerView 有一种方法可以监听 onClick 事件，但我不太明白.

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

由于 API 发生了根本性的变化，如果您为每个项目创建一个 OnClickListener，我不会感到惊讶.不过也没有那么麻烦.在您的 RecyclerView.Adapter 实现中，您应该:

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 viewType) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.myview, parent, false);
    view.setOnClickListener(mOnClickListener);
    return new MyViewHolder(view);
}

onClick 方法:

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