Dagger2片段注入

Question

尝试学习Dagger2并使用Dagger2 2.14.1。我无法过去：

no suitable method found for inject(SettingsFragment)

SettingsFragment是：

public class SettingsFragment extends PreferenceFragmentCompat implements SharedPreferences.OnSharedPreferenceChangeListener {
....
 @Override
public void onAttach(Context context){
    AndroidInjection.inject(this);     <<<< Error here
    super.onAttach(context);
}}

因为我无法从DaggerFragment扩展PreferenceFragmentCompat。

我的建筑商模块是

@Module(subcomponents = {SettingsFragmentSubComponent.class, StartupPhotoFragmentSubComponent.class })
public abstract class UIBuildersModule {

@Binds
@IntoMap
@FragmentKey(SettingsFragment.class)
abstract AndroidInjector.Factory<? extends Fragment> bindSettingsFragmentInjectorFactory(SettingsFragmentSubComponent.Builder builder);

//    @ContributesAndroidInjector    <<< tried also without luck.
//    abstract SettingsFragment bindSettingsFragment();

@ContributesAndroidInjector
abstract StartupPhotoFragment bindStartupPhotoFragment();

我确实为SettingsFragment创建了模块和子组件，但它们确实是空的，因为我想获取在应用程序级别创建的依赖项：

@Module
public class SettingsFragmentModule {
}

@Subcomponent(modules = {SettingsFragmentModule.class})
public interface SettingsFragmentSubComponent extends 
AndroidInjector<SettingsFragment> {

@Subcomponent.Builder
abstract class Builder extends AndroidInjector.Builder<SettingsFragment> {
}}

编辑：添加了包括UIBuildersModule和build.gradle中的代码段的ApplicationComponent

@Singleton
@Component(modules = {UIBuildersModule.class, 
AndroidSupportInjectionModule.class, ApplicationModule.class, })
public interface ApplicationComponent extends
    AndroidInjector<ActivityTrackerApplication> {

@Component.Builder
interface Builder {
    @BindsInstance
    Builder application(ActivityTrackerApplication application);
    ApplicationComponent build();
}
void inject(ActivityTrackerApplication activityTrackerApplication);
void inject(StartupPhotoFragment startupPhotoFragment);
void inject(SettingsFragment settingsFragment);

}

这也是build.gradle的片段

final DAGGER_VERSION="2.14.1"
 ....
// For Dagger2
compile "com.google.dagger:dagger:$DAGGER_VERSION"
compile "com.google.dagger:dagger-android:$DAGGER_VERSION"
compile "com.google.dagger:dagger-android-support:$DAGGER_VERSION"
annotationProcessor "com.google.dagger:dagger-android-processor:$DAGGER_VERSION"
annotationProcessor "com.google.dagger:dagger-compiler:$DAGGER_VERSION"

EDIT2：解决方案 Ahh-当然可以。

public class SettingsFragment extends PreferenceFragmentCompat implements SharedPreferences.OnSharedPreferenceChangeListener {
....
 @Override
public void onAttach(Context context){
    AndroidSupportInjection.inject(this); <<<<Needed AndroidSupportInjection
    super.onAttach(context);
}}
