Question

我在启动服务的活动中有一个alarmManager。我想获得我的演示者的一个实例我的服务。我在我的项目中使用了Dagger 2来处理依赖注入。这是我的代码：

我每小时开始/停止服务的活动：

public class ActionsActivity extends ActivityBase {

    @Inject
    ActionsActivityPresenter mPresenter;

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

    ((App)getApplication()).getMyComponent()
    .plus(new ActionsActivityModule()).inject(this);
    ..........
    Intent intent = new Intent(this, EventsService.class);
    PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, 0);
    AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarm.cancel(pendingIntent);
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),minuteInMillies * 60, pendingIntent);
    ........
}

这是我的模块：

@Module(includes = {ContextModule.class, ScannerActivityModule.class})
public class ActionsActivityModule {

.........

@AppScope
@Provides
public RemoveShiftEvent removeShiftEvent(ShiftEventDatabase shiftEventDatabase) {
    return new RemoveShiftEventImpla(shiftEventDatabase);
}

@AppScope
@Provides
public ActionsActivityPresenter actionsActivityPresenter(InsertShiftEvent insertShiftEvent, SendShiftEvent sendShiftEvent, RemoveShiftEvent removeShiftEvent, NameEncryptor nameEncryptor) {
    return new ActionsActivityPresenter(insertShiftEvent, sendShiftEvent, removeShiftEvent, nameEncryptor);
}
......

}

最后我的服务暂时没有发生任何事情

public class EventsService extends Service {

public EventsService() {
}

private ActionsActivityPresenter actionsActivityPresenter;

@Override
public IBinder onBind(Intent intent) {
    // TODO: Return the communication channel to the service.
    return null;
}


@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Timber.d( "onStartCommand Service has started");
    return super.onStartCommand(intent, flags, startId);
}

@Override
public void onCreate() {
    super.onCreate();
}


@Override
public void onDestroy() {
    super.onDestroy();

}

我的问题是，有没有办法使用dagger框架在我的服务中注入我的ActionsActivityPresenter？提前谢谢。

您可以在服务中使用注射器，如活动/片段注射器

@Module(includes = [AndroidSupportInjectionModule::class, ActivityBuilderModule::class, ServiceBuilderModule::classs])
abstract class ApplicationModule
{
    @Binds
    @Singleton
    abstract fun bindApplication(application: BeaverApplication): Application

    @Module
    companion object
    {
        @Provides
        @Singleton
        @ApplicationContext
        @JvmStatic
        fun provideApplicationContext(application: BeaverApplication): Context = application
    }
}

喜欢你＆＃34;贡献注射器＆＃34;对于活动/片段，对服务也这样做：

@Module
abstract class ServiceBuilderModule
{
    @ContributesAndroidInjector
    abstract fun contributeAuthenticatorService(): AuthenticatorService
}

您从我的projet模板here获得了一个具有AuthenticatorService类
