广播接收器未接收 android.Looking 中的意图数据，解决方案

Question

我正在尝试将意图数据发送到 MainActivity。我正在从 GCM Server 接收数据，我想将接收到的数据发送到我的 MainActivity。

在 GcmBroadcastReceiver Class

    ComponentName comp = new ComponentName(context.getPackageName(),
      GcmIntentService.class.getName());
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);

    Bundle extras = intent.getExtras();
    Intent i = new Intent("CHAT_MESSAGE_RECEIVED");
    i.putExtra("Message", extras.getString("Message"));
    i.putExtra("Sender",extras.getString("Sender"));
    i.putExtra("Receiver",extras.getString("Receiver"));
    i.putExtra("Calltype",extras.getString("calltype"));
    context.sendBroadcast(i);

我使用以上代码从 GCM Sever 接收数据，并使用 BroadcastReceiver 发送数据。

在MainActivity中Class

registerReceiver(broadcastReceiver,newIntentFilter("CHAT_MESSAGE_RECEIVED"));
BroadcastReceiver broadcastReceiver = new BroadcastReceiver() { 
    @Override
    public void onReceive(Context context, Intent intent) {           
        Bundle b = intent.getExtras();
        String message = b.getString("Message");
        String sender=b.getString("Sender");
        String receiver=b.getString("Receiver");
    }
};

在activity中我使用了广播接收器来接收带有数据的意图。

Answer 1

想知道您是否在 AndroidManifest.xml 中声明了 BroadcastReceiver。

<receiver android:name=".YourBroadCastReceiver" />

Answer 2

In your GcmListenerService # onMessageRecieved() function use this code
 Intent intent = new Intent(ANY_TAG);
        sendBroadcast(intent);

AND in your activity use following code

 private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            displayToast(" Data received");
        }
    };

 @Override
    public void onResume() {
        super.onResume();
        getContext().registerReceiver(mMessageReceiver, new IntentFilter(ANY_TAG));
    }

    @Override
    public void onPause() {
        super.onPause();
        getContext().unregisterReceiver(mMessageReceiver);
    }

// 使用可观察对象作为接口

public class ObservableObject extends Observable {
private static ObservableObject instance = new ObservableObject();

public static ObservableObject getInstance() {
    return instance;
}

private ObservableObject() {
}

public void updateValue(Object data) {
    synchronized (this) {
        setChanged();
        notifyObservers(data);
    }
}
}

// 主接收器

public class MainReceiver extends        BroadcastReceiver 
 {
public final static String MAINRECEIVERSETALARM="ir.shes.schedule.MainReceiver.setalarm";
public final static String MAINRECEIVERSNOOZE="ir.shes.schedule.MainReceiver.snooze";

@Override
public void onReceive(Context p1, Intent p2)
{

    ObservableObject.getInstance().updateValue(p2);

}


}

// 主活动

public class MainActivity extends Activity implements Observer 
{
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    ObservableObject.getInstance().addObserver(this);
}
@Override
public void update(Observable observable, Object data) {        

    String action=((Intent)data).getAction();
    if (action.equals(MainReceiver.MAINRECEIVERSETALARM))
        app.eventCache.setAlarm();
    if (action.equals(MainReceiver.MAINRECEIVERSNOOZE))
        Toast.makeText(this, "snooze", Toast.LENGTH_LONG).show();
}
}

// AndroidManifest.xml

中的静态寄存器接收器

<receiver android:name="ir.shes.schedule.MainReceiver">
        <intent-filter>     

            <action android:name="ir.shes.schedule.MainReceiver.setalarm" />
            <action android:name="ir.shes.schedule.MainReceiver.snooze" />

        </intent-filter>

    </receiver>
