如何在android中接收短信？

Question

我是新來的android和我使用android 2.1的一些sms_receive事情：當一個短信收到，它不會工作......我有一個力量關閉，幫助！

public class SmsReceiverActivity extends Activity { 
    private static final String SHORTCODE = "55443"; 
    public void onReceive(Context context, Intent intent) { 
     Bundle bundle = intent.getExtras(); 
     Object[] messages = (Object[]) bundle.get("pdus"); 
     SmsMessage[] sms = new SmsMessage[messages.length]; 
     //Create messages for each incoming PDU 
     for (int n = 0; n < messages.length; n++) { 
      sms[n] = SmsMessage.createFromPdu((byte[]) messages[n]); 
     } 
     for (SmsMessage msg: sms) { 
      //Verify if the message came from our known sender 
      if (TextUtils.equals(msg.getOriginatingAddress(), "SHORTCODE")) { 
       Toast.makeText(context, "Received message from the mothership: " + msg.getMessageBody(),Toast.LENGTH_SHORT).show(); 
      } 
     } 
} 

Android清單：

<uses-sdk android:minSdkVersion="7" /> 
<uses-permission android:name="android.permission.RECEIVE_SMS"/> 
<application android:label="@string/app_name"> 
    <activity 
     android:name=".SmsReceiver" 
     android:label="@string/app_name"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    <receiver android:name=".SMSReceiver" android:enabled="true"> 
     <intent-filter android:priority="100"> 
      <action android:name="android.provider.Telephony.SMS_RECEIVED" /> 
     </intent-filter> 
    </receiver> 
</application> 

安裝程序，我想運行它的時候，我有密切的力量，這是我的logcat：

Answer 1

我認爲你需要Manifest.xml like：

<receiver android:name=".SmsReceiver"> 
    <intent-filter android:priority="100"> 
     <action android:name="android.intent.action.PHONE_STATE" /> 
     <action android:name="PACKAGE_NAME.android.action.broadcast"/> 
     <action android:name="android.provider.Telephony.SMS_RECEIVED"></action> 
    </intent-filter> 
</receiver> 

，改變你的類名SmsReceiverActivity到SmsReceiver，也是你的類需要擴展廣播接收器。

Answer 2

你需要一個BroadcastReceiver在應用程序中閱讀短信。您可以使用以下內容。

public class SmsReceiver extends BroadcastReceiver { 

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

     Object[] pdus = (Object[]) intent.getExtras().get("pdus"); 

     SmsMessage shortMessage = SmsMessage.createFromPdu((byte[]) pdus[0]); 

     Log.i("sms received", "sms received"); 
     Log.i("SMS: ", shortMessage.getDisplayMessageBody()); 
    } 
} 

此外，您還需要通過以下方式將其聲明到您的應用程序中。

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

不要忘記添加到SMS相關的權限，如以下

<uses-permission android:name="android.permission.READ_SMS"/> 
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
