- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我正在尝试开始一个小项目,遵循干净的架构、MVVM 并使用 Retrofit、协程等。我正在使用 Hilt 进行 DI,并且几乎遵循了我在文档和其他项目中看到的内容。
如果我用@AndroidEntryPoint 注释我的Activity 或我的Fragment 或用@HiltAndroidApp 注释应用程序,应用程序甚至无法启动。堆栈跟踪对我来说并没有说太多,但也许我正在跳过一些东西。如果我不注释类,应用程序会尝试启动,但由于它无法从任何地方注入(inject) ViewModel,它显然会崩溃。

我将在这里留下我的部分代码,如果我还需要提供任何其他内容,请告诉我,到目前为止它还很基本。
应用程序
@HiltAndroidApp
class SearchSpotifyApp: Application(){
}
Activity
@AndroidEntryPoint
class MainActivity: AppCompatActivity(){
private var binding: ActivityMainBinding? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = DataBindingUtil.setContentView(
this,
R.layout.activity_main
)
}
override fun onDestroy() {
binding = null
super.onDestroy()
}
}
fragment
@AndroidEntryPoint
class SearchFragment : Fragment() {
private lateinit var binding: FragmentSearchBinding
private val searchViewModel: SearchViewModel by viewModels()
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
binding = FragmentSearchBinding.inflate(inflater)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
initViews()
}
private fun initViews() {
searchViewModel.getSongs().observe(viewLifecycleOwner, {
binding.text.text = it.first().title
})
}
}
模块
private const val BASE_URL = "http://google.es"
@Module
@InstallIn(ApplicationComponent::class)
object AppModule {
@Singleton
@Provides
fun provideRetrofit(gson: Gson): Retrofit = Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.build()
@Provides
fun provideGson(): Gson = GsonBuilder().create()
@Provides
fun provideSearchDataSource(retrofit: Retrofit): SearchDataSource =
retrofit.create(SearchDataSource::class.java)
@Singleton
@Provides
fun provideSearchRepository(searchDataSource: SearchDataSource) =
SearchRepositoryImpl(searchDataSource)
@Provides
fun provideSearchViewModel(repository: SearchRepository) =
SearchViewModel(repository)
}
我很确定我错过了一些我没有看到的非常基本的东西,因为我不熟悉设置 DI 框架。提前非常感谢。
