我怎麼設置廣播reciever

Question

我想成立一​​個廣播reciever運行某些功能時，它得到的廣播消息，在這個例子中，我要趕在下載的管理意圖：

DownloadManager.ACTION_DOWNLOAD_COMPLETE 

我看着在Android的API例子，還沒有找到一個辦法做到這一點

Answer 1

你應該閱讀這首：

http://developer.android.com/reference/android/content/BroadcastReceiver.html

然後看看在這裏˚F或例子。

Android的樣品：http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/appwidget/ExampleBroadcastReceiver.html

Answer 2

試試這個：

BroadcastReceiver receiver = new BroadcastReceiver() { 

    @Override 
    public void onReceive(Context context, Intent intent) { 
    String action = intent.getAction(); 
    if (action.equals(DownloadManager.ACTION_DOWNLOAD_COMPLETE)){ 
     // do something 
    } 
    } 

registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE)); 

Answer 3

您可以創建一個類，從BroadcastReceiver繼承：

public class MyDownloadCompleteReceiver extends BroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 
    } 
} 

然後在您的應用程序清單中註冊此類，如下所示：

<receiver android:enabled="true" 
       android:name="MyDownloadCompleteReceiver" 
       android:label="downloadCompleteReceiver"> 
     <intent-filter> 
      <action android:name="android.intent.action.DOWNLOAD_COMPLETE" /> 
     </intent-filter> 
    </receiver>
