java - 在 RecyclerView 中访问同一行中的所有元素

Question

我有一个回收 View ，如图所示，每行包含两个按钮

我已将 onClickListener 添加到 Button-A

如果用户单击按钮 A，是否可以访问同一行中的按钮 B在同一行？

class BooksHolder extends RecyclerView.ViewHolder{

    public BooksHolder(View itemView) {
        super(itemView);
        Download=(Button)itemView.findViewById(R.id.download);
        pb=(ProgressBar)itemView.findViewById(R.id.progressBar1) ;
        Download.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Download.setVisibility(Button.INVISIBLE);
                new DelayTask().execute();

            }
        });
    }
}

public class DelayTask extends AsyncTask<Void, Integer, String> {
    int count=0 ;
    @Override
    protected void onPreExecute() {
        pb.setVisibility(ProgressBar.VISIBLE);

    }

    @Override
    protected String doInBackground(Void... params) {
        while (count < 5) {
            SystemClock.sleep(1000);
            count++;
            publishProgress(count * 20);
        }
        return "Complete";
    }

    @Override
    protected void onProgressUpdate(Integer... values) {
        pb.setProgress(values[0]);

    }

    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        SystemClock.sleep(100);
        pb.setVisibility(ProgressBar.INVISIBLE);
        Download.setVisibility(Button.VISIBLE);
        Download.setEnabled(false);
    }
}

下载按钮已在适配器中声明pb是ProgressBar已经在Adapter中声明了

您可以在 viewHolder 中实现 onClickListener

示例

static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
Button button1;
Button button2;

public MyViewHolder(View itemView) {
    super(itemView);
    button1 = (Button) itemView.findViewById(R.id.button1);
    button2 = (Button) itemView.findViewById(R.id.button2);

    button1.setOnClickListener(this);
    button2.setOnClickListener(this);
}

@Override
public void onClick(View view) {
    if (view == button1) {
        // your action here
    } else if (view == button2) {
        // your action here
    }
}
}
