Question

您好我开发了一个小型Android应用程序，其中我使用一个活动一个意图服务和一个广播接收器。所以我的代码看起来像：

public class Main_Activity extends Activity {

    private ResultReceiver resultReciver;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_);
        Log.i("***************************88", "inside activity on create");

        IntentFilter filter = new IntentFilter("com.nilkash.broadcast.receiver");
        resultReciver = new ResultReceiver();
        registerReceiver(resultReciver, filter);
        //LocalBroadcastManager.getInstance(this).registerReceiver(resultReciver, filter);

        Intent intent = new Intent(this, ExampleService.class);
        startService(intent);

    }

    public class ResultReceiver extends BroadcastReceiver{

        public ResultReceiver()
        {

        }
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            // TODO Auto-generated method stub
            Log.i("**********************", "inside broadcast receiver: ");
        }

    }

}

意图服务

public class ExampleService extends IntentService{


    public ExampleService(String value)
    {
        super(value);
    }

    public ExampleService()
    {
        super("");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        // TODO Auto-generated method stub
        Log.i("********************************", "inside intetn reciver: ");
        Intent broadcastIntent = new Intent();
        broadcastIntent.setAction("com.nilkash.broadcast.receiver");
        //broadcastIntent.putExtra("value", "nilkash");
        sendBroadcast(intent);
        //LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
    }
}

在清单文件中我定义服务。所以我的问题是我从活动开始服务并且工作正常。从意向接收服务我发送了一个广播接收器，但它没有在我的广播接收器内收听。

我做错了吗？需要帮忙。谢谢。

出现错误：sendBroadcast(intent);。应该是另一个意图对象（broadcastIntent）。

Android广播接收器不使用意图接收器
