如何將數據傳遞給BroadcastReceiver？

Question

我想要做的是，我的應用程序發送消息到的數字，傳遞給BraodcastReceiver ...但到目前爲止，我得到空或BroadcastReceiver只是簡單地崩潰..

這是我的意圖從類的CreateMessage的BroadcastReceiver ...

 Intent intent = new Intent(); 
     Bundle bundle = new Bundle(); 
     bundle.putString("phN", phoneNo); 
     intent.putExtras(bundle); 
     startActivity(intent); 

而且在廣播接收器（SmsReceiver類），我試圖抓住意圖這樣的..

public void onReceive(Context context, Intent intent) { 
    //---get the SMS message passed in--- 
    Bundle bundle = intent.getExtras(); 
    try{ 
    //receiveNumbers = intent.getExtras().get("phN").toString(); 
     String receiveNumbers = intent.getStringExtra("phN"); 
     Toast.makeText(context, receiveNumbers, Toast.LENGTH_LONG).show(); 
    }catch(Exception e){ 
     e.printStackTrace(); 
    } 

我的清單文件：

      <action android:name="android.provider.Telephony.SMS_RECEIVED"/> 
      </intent-filter> 
      </receiver> 
    </application> 

</manifest> 

我已經嘗試給出了＃1所有的答案...但是沒有用......

請你們告訴我，我錯了...謝謝！

Answer 1

繼@Jason的榜樣......我這樣做...

在MainActivity或任何活動在那裏，你想從

Intent intent = new Intent("my.action.string"); 
intent.putExtra("extra", phoneNo); \\ phoneNo is the sent Number 
sendBroadcast(intent); 

然後發送意圖在我SmsReceiver類我這樣做

public void onReceive(Context context, Intent intent) { 
    String action = intent.getAction(); 

    Log.i("Receiver", "Broadcast received: " + action); 

    if(action.equals("my.action.string")){ 
    String state = intent.getExtras().getString("extra"); 

    } 
} 

而且在我manifest.xml中添加"my.action.string"雖然這是一個選項..

<receiver android:name=".SmsReceiver" android:enabled="true"> 
    <intent-filter> 
     <action android:name="android.provider.Telephony.SMS_RECEIVED" /> 
     <action android:name="my.action.string" /> 
     <!-- and some more actions if you want --> 
    </intent-filter> 
</receiver> 

工作般的魅力！

Answer 2

您在開始Activity，而不是廣播Intent。 嘗試改變

startActivity(intent); 

到

sendBroadcast(intent); 

UPDATE：

您可以設置任何動作，沒有組件名稱爲Intent。 嘗試創建意向如下：

Intent intent = new Intent(context, YourReceiver.class); 
intent.putExtra("phN", phoneNo); 
sendBroadcast(intent); 

Answer 3

你會發送一個廣播，像這樣：

Intent intent = new Intent(action); 
intent.putExtra("phN", phoneNo); 
sendBroadcast(intent); 

的action參數是String相關於您註冊的BroadcastReceiver的動作。所以，如果您註冊的接收器，像這樣：

MyBroadcastReceiver receiver = new MyBroadcastReceiver(); 
registerReceiver(receiver, new IntentFilter("com.myapp.myaction")); 

然後action將"com.myapp.myaction"

Answer 4

使用sendbroadcast而不是startactivity.it將工作.. !!

Answer 5

你的問題很簡單。只要改變onRecive（）代碼就足夠了：

public void onReceive(Context context, Intent intent) { 
    String action = intent.getAction(); 

    Log.i("Receiver", "Broadcast received: " + action); 

    if(action.equals("my.action.string")){ 
     String state = bundle.getString("phN"); 

    } 
}
