当我收到广播时显示AlertDialog吗？在SDK >= 23中

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.support.v7.app.AlertDialog;

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 处理接收到的广播逻辑
        // ...

        // 创建AlertDialog.Builder对象
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setTitle("提示");
        builder.setMessage("您收到了一条广播消息！");
        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 用户点击确定按钮后的逻辑
                // ...
            }
        });

        // 显示AlertDialog
        AlertDialog alertDialog = builder.create();
        alertDialog.show();
    }
}
