BroadcastReceiver之发送自定义无序广播

首先，发送一个自定义广播：（用sendBroadcast(intent)发送一条无序广播）

public void  click(View v){
        Intent intent = new Intent();
        intent.putExtra("msg","我是一条无序广播");
        intent.setAction("com.coderwei.myBroadcast");
        sendBroadcast(intent);
    }

然后自定义一个类继承BroadcastReceiver接收广播，先配置Manifest.xml

<receiver android:name=".ReceiverBroadcast">
            <intent-filter>
                <action android:name="com.coderwei.myBroadcast"/>
            </intent-filter>
 </receiver>

接收这个广播，输出携带的数据

public class ReceiverBroadcast extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String str = intent.getStringExtra("msg");
        System.out.println(str);
    }
}

ps：上面的action需要自定义的
