RecyclerView 实现 OnItemClickListener

新的 widget RecyclerView 不知出于什么样的考虑并没有像 ListView 那样提供 OnItemClickListener 需要自己来实现。 我想到了这个方法来实现。

//XxxRecyclerViewAdapter.java
...
private OnItemClickListener onItemClickListener = null;

public interface OnItemClickListener {
    onItemClick(View v, int p);
}




//ViewHolder实现中
public final class ListHolder
        extends RecyclerView.ViewHolder {

    public ListHolder(View itemView) {
        super(itemView);

        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (onItemClickListener != null) {
                    onItemClickListener.onItemClick(v, getPosition());
                }
            }
        });
    }

}

public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
    this.onItemClickListener = onItemClickListener;
}
...



使用时只要为 adapter 设置 OnItemClickListener 就好了

//实现文件
private XxxRecyclerViewAdapter adaoter;

void init() {
...
    view.setAdapter(adapter);
    this.adapter.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(View view, int position) {
            //do something...
        }
    });

...
}

总算是实现了功能 ^_^
