BroadcastReceiver之發送自定義無序廣播 - Coderwei2016－IT工程師數位筆記本

首先，發送一個自定義廣播：（用sendBroadcast(intent)發送一條無序廣播）

1 public void  click(View v){
2         Intent intent = new Intent();
3         intent.putExtra("msg","我是一條無序廣播");
4         intent.setAction("com.coderwei.myBroadcast");
5         sendBroadcast(intent);
6     }

然后自定義一個類繼承BroadcastReceiver接收廣播，先配置Manifest.xml

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

接收這個廣播，輸出攜帶的數據

1 public class ReceiverBroadcast extends BroadcastReceiver {
2     @Override
3     public void onReceive(Context context, Intent intent) {
4         String str = intent.getStringExtra("msg");
5         System.out.println(str);
6     }
7 }
