Question

我正在构建一个未读的短信中继应用程序。有电话A和B，当A收到短信而没有人看过它时，我的应用程序将其转发给B.但我发现当A收到短信时，会显示一个系统通知。我的ContentObserver onChange()方法仅在我取消通知后才会调用。收到短信后我该怎么做才能收到未读短信？

ContentObserver：

public NewIncomingContentObserver(Handler handler, Application 

application) {
    super(handler);
    this.mApplication = application;
  }

  @Override
  public void onChange(boolean selfChange) {
    System.out.println(selfChange);
    super.onChange(selfChange);
    Uri uri = Uri.parse(SMS_URI_INBOX);
    mMessageListener.OnReceived(this.getSmsInfo(uri, mApplication));
  }

  /**
   * get the newest SMS
   */
  private SmsInfo getSmsInfo(Uri uri, Application application) {
    ...
  }

  public interface MessageListener {
    public void OnReceived(SmsInfo smsInfo);
  }

  public void setOnReceivedMessageListener(
          MessageListener messageListener) {
    this.mMessageListener = messageListener;
  }
}

服务：

public class SmsListenerService extends Service {
  public static final String URI = "content://sms/inbox";

  public SmsListenerService() {
  }

  @Override
  public IBinder onBind(Intent intent) {
    throw new UnsupportedOperationException("Not yet implemented");
  }

  @Override
  public int onStartCommand(Intent intent, int flags, int startId) {
    //Register observer
    NewIncomingContentObserver smsContentObserver =
            new NewIncomingContentObserver(new Handler(), getApplication());

    this.getContentResolver().registerContentObserver
            (Uri.parse(URI), true, smsContentObserver);

    smsContentObserver.setOnReceivedMessageListener(new NewIncomingContentObserver.MessageListener() {
      @Override
      public void OnReceived(SmsInfo smsInfo) {
        System.out.println(smsInfo);
      }
    });
    return START_NOT_STICKY;
  }
}

借用（https://github.com/Pyo25/Phonegap-SMS-reception-plugin）的示例，示例是一个phonegap插件，但您仍然可以使用它：

public class SmsReceiver extends BroadcastReceiver {
    public static final String SMS_EXTRA_NAME = "pdus";

    // This broadcast boolean is used to continue or not the message broadcast
    // to the other BroadcastReceivers waiting for an incoming SMS (like the native SMS app)
    private boolean broadcast = false;

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

        // Get the SMS map from Intent
        Bundle extras = intent.getExtras();
        if (extras != null)
        {
           // Get received SMS Array
            Object[] smsExtra = (Object[]) extras.get(SMS_EXTRA_NAME);

            for (int i=0; i < smsExtra.length; i++)
            {
                SmsMessage sms = SmsMessage.createFromPdu((byte[]) smsExtra[i]);

                    String formattedMsg = sms.getOriginatingAddress() + ">" + sms.getMessageBody();

            }

            // If the plugin is active and we don't want to broadcast to other receivers
            if (!broadcast) {
                this.abortBroadcast();
            }
         }
    }
}

在我的AndroidManifest中：

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

SMS Inbox not refereshing

我认为短信收件箱是由特定的短信应用管理的。因此，通过content://sms/inbox收听新短信是我的应用程序中特定于SMS应用程序的解决方案。 @Niels的回答可能是更好的解决方案。
