如何在主要活动中注册接收者？

Question

我有一个SmsReceiver课程，我想在主要活动中注册，我应该怎么做？

我是安卓新手。

Answer 1

要么你可以做两件事：

1. 创建和定义BroadcastReceiver的Manifest
2. 创建并注册BroadcastReceiverin 代码。

对于选项 2（您要问的）：

创建一个BroadcastReceiverin 代码 (MyBroadcastReceiver)。在您的范围内声明 MyBroadcastReceiver Activity：

MyBroadcastReceiver mMyBroadcastReceiver;

注册BroadcastReceiver您的Activity是：

IntentFilter filter = new IntentFilter(android.provider.Telephony.SMS_RECEIVED);
this.registerReceiver(mMyBroadcastReceiver, filter);
