給多個廣播接收者傳送廣播、有序廣播的使用在安卓開發中是經常使用的方式，下面我們來介紹一下它的使用方法。

整體思路：在xml檔案中放置兩個Button控制元件，給這兩個Button控制元件設定點選事件，在第一個點選事件中傳遞一個數據，設定一個動作併發送廣播，在第二個點選事件中傳遞一個數據，設定一個動作併發送有序廣播。新建三個繼承BroadcastReceiver的廣播接收類，用於接收傳遞的資料。在第二個BroadcastReceiver子類中停止廣播的接收，發現在傳送有序廣播的時候會影響後續廣播接收者進行接收廣播。在清單檔案註冊者三個廣播接收類，並設定它們的優先順序和行為。

activity_main.xml檔案：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="41dp"
        android:text="給多個廣播接收者傳送廣播" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/button1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="53dp"
        android:text="傳送有序廣播" />

</RelativeLayout>

		 System.out.println("Broadcast2-->"+intent.getStringExtra("name"));
		 abortBroadcast();//結束廣播，如果是有序廣播的話則不繼續傳送後面的廣播
		 }

				// TODO Auto-generated method stub
				Intent intent=new Intent();
				intent.putExtra("name", "rose");
				intent.setAction("com.mybroadcast.sender");//設定一個動作
//				傳送有序廣播
				sendOrderedBroadcast(intent, null);
			}
		});
		
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}

 <!-- 傳送廣播的順序會根據優先順序的大小  優先順序大的先發送-->
