如何在 RecyclerView 上设置 onClickListener

Question

我有一个简单的问题，我不能在 recyclerview 上设置 onClickListener ，我不想在 recyclerview 的项目上设置 onClickListener ，只是 recyclerview 本身，我尝试了普通的方法，它没有工作

（我试图在父布局上设置一个 onClickListener，但奇怪的是它不起作用，因为我在 recyclerview 上设置了 LinearLayoutManager :|）

这是我的代码：

mRecyclerView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d("onClick","Clicked");
        }
    });

适配器：

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {
private List<Message> mMessage;

public static class ViewHolder extends RecyclerView.ViewHolder{
    private TextView txtSender;
    private TextView txtMessage;

    public ViewHolder(View v) {
        super(v);
        txtSender = (TextView) v.findViewById(R.id.txtSender);
        txtMessage = (TextView) v.findViewById(R.id.txtText);
    }

}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View inflatedView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.recyclerview_item_row, parent, false);
    return new ViewHolder(inflatedView);
}


public RecyclerAdapter(List<Message> messages) {
    mMessage = messages;
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    Message msg = mMessage.get(position);
    holder.txtSender.setText(msg.getSender());
    holder.txtMessage.setText(msg.getmessage());
}

@Override
public int getItemCount() {
    return mMessage.size();
}

根据您的需要，您需要修改R.layout.recyclerview_item_row。使用 android LinearLayout 将 TextView(R.id.txtSender 和 R.id.txtText) 都放在里面。

修改你的ViewHolder如下：

public static class ViewHolder extends RecyclerView.ViewHolder
{
private LinearLayout lvContainer;
private TextView txtSender;
private TextView txtMessage;

public ViewHolder(View v) {
    super(v);
    lvContainer = (LinearLayout) v.findViewById(R.id.lv_container); // R.id.lv_container this should be in your R.layout.recyclerview_item_row
    txtSender = (TextView) v.findViewById(R.id.txtSender);
    txtMessage = (TextView) v.findViewById(R.id.txtText);
}
}

如下修改你的onBindViewHolder

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
Message msg = mMessage.get(position);
holder.txtSender.setText(msg.getSender());
holder.txtMessage.setText(msg.getmessage());
holder.lvContainer.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //Handle your click here
    }
});
}
