自定义广播

1、发送一条标准广播：

Intent intent = new Intent("com.example.broadcasttest.MY_BROADCAST");
sendBroadcast(intent);

2、发送一条有序广播：

Intent intent = new Intent("com.example.broadcasttest.MY_BROADCAST");
sendOrderedBroadcast(intent, null);

3、可在接收器注册的时候设置优先级：

<receiver android:name="com.example.zds.broadcast_test.MyReceiver">
    <intent-filter android:priority="100">
        <action android:name="com.example.zds.broadcast_test.MYBROADCAST"/>
    </intent-filter>
</receiver>

4、在接收器中截断广播，只需要调用abortBroadcast()方法。

public void onReceive(Context context, Intent intent) {
    Toast.makeText(context,"自定义接收器接收到",Toast.LENGTH_LONG).show();
    abortBroadcast();
}
