从服务中将数据发送到片段

Question

我的服务中有一个字符串，我想将其发送到片段。但似乎我的BroadcastReceiver上的onReceive（）方法从未调用过，我只是无法弄清楚原因。谢谢你的回答。

我的服务类

public class Servis extends Service {
static final String MAP = "MyService";
static final String USERID = "";

public static final String FILEPATH = "filepath";

@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
    System.out.println("starting service");
    Toast.makeText(this, "service starting", Toast.LENGTH_SHORT).show();
    String id = intent.getStringExtra("UserID");
    System.out.println(id);

    Intent intent1 = new Intent(MAP);
    intent1.putExtra(USERID, id);
    sendBroadcast(intent1);

    return START_REDELIVER_INTENT;
}

@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public void onCreate() {
    Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
    Log.d(MAP, "onCreate");
}

@Override
public void onDestroy() {
    Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
    Log.d(MAP, "onDestroy");
}

@Override
public void onStart(Intent intent, int startid) {
    Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
    Log.d(MAP, "onStart");
}

}

我的片段类

package com.example.mobilproje;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapFragment extends FragmentActivity{

private GoogleMap googleHarita;

private BroadcastReceiver receiver = new BroadcastReceiver() {

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

        Bundle bundle = intent.getExtras();
        handleResult(bundle);
    }

};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.map_fragment);

    registerReceiver(receiver, new IntentFilter(
            Servis.MAP));

    if (googleHarita == null) {            
     googleHarita = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.haritafragment))  
                .getMap(); 
        if (googleHarita != null) 
            LatLng EvKoordinat = new LatLng(40.7994211,29.9517352);
            googleHarita.addMarker(new MarkerOptions().position(EvKoordinat).title("Ev"));
            googleHarita.moveCamera(CameraUpdateFactory.newLatLngZoom(EvKoordinat, 13));         
        }
    }

}

@Override
public void onResume() {        
    registerReceiver(receiver, new IntentFilter(
            Servis.MAP));
}

private void handleResult(Bundle bundle) {
    if (bundle != null) {
        String string = bundle.getString(Servis.USERID);
        System.out.println("string");
        }
    }
}
