推荐答案

您可以做两件事:

1. 在Manifest
中创建并定义BroadcastReceiver
2. 在代码中创建并注册BroadcastReceiver.

对于选项2(您要询问的内容):

For option 2 (which you are asking):

在代码(MyBroadcastReceiver)中创建一个BroadcastReceiver. 在您的Activity范围内声明MyBroadcastReceiver:

Create a BroadcastReceiver in code (MyBroadcastReceiver). Declare MyBroadcastReceiver in the scope of your Activity:

MyBroadcastReceiver mMyBroadcastReceiver;

通过以下方式在Activity中注册BroadcastReceiver:

Register the BroadcastReceiver in your Activity by:

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