我有一个Android应用程序,我正在尝试使用匕首.我决定使用全局图活动图.我有三个模块:
AndroidModule
@Module(library = true)
public class AndroidModule {
private final MApplication mApplication;
public AndroidModule(MyApplication application) {
mApplication = application;
}
@Provides @Singleton @ForApplication Context provideApplicationContext() {
return mApplication;
}
}
MyAppModules
@Module(
injects = {
MainActivity.class,AddFragment.class,AddMapFragment.class,MyActivity.class,ListFragment.class,MyMapFragment.class,RetainFragment.class,SingleActivity.class,UserActivity.class,UserLoginFragment.class,UserProfileActivity.class,UserProfileFragment.class,UserRegisterFragment.class,WelcomeFragment.class
},complete = false,library = true,includes = ActivityModule.class
)
public class MyAppModule {
private final Bus mBus = new Bus();
@Provides @Singleton Bus provideBus() {
return mBus;
}
@Provides @Singleton
RequestQueue provideRequestQueue(@ForApplication Context context) {
return Volley.newRequestQueue(context);
}
@Provides @Singleton Api provideApi(RequestQueue queue) {
return new AppApi(queue);
}
@Provides Logger provideLogger() {
return new MyLogger();
}
}
ActivityModule
@Module(
complete = false,library = true
)
public class ActivityModule {
private BaseActivity mActivity;
public ActivityModule() {}
public ActivityModule(BaseActivity activity) {
mActivity = activity;
}
@Provides @Singleton @ForActivity Context provideActivityContext() {
return mActivity;
}
@Provides @Singleton LocationClientFactory provideLocationClientFactory() {
return new LocationClientFactory(mActivity);
}
}
我不得不在MyAppModule上使用include作为ActivityModule,没有它,应用程序崩溃说它可以在Context上找到一个构造函数并且无法注入Activity的Context.
图表配置正确吗?我将模块添加到应用程序和BaseActivity中的图形中,我认为这已经足够了,我不需要包含,但我不确定我完全理解这个的配置过程.
编辑
像这样,dagger没有错误但是如果我尝试注入一个Activity Context,那么在运行时它就是null.
