I have a problem with injection dagger into view model.The problem is that losing form inputs when rotating the screen.Is the problem in my injection or initialize my view model? Here is my viewmodel;
@HiltViewModel
class ProfilIslemViewModel @Inject constructor(application: Application,
private val kullaniciService: KullaniciService,
private val kullaniciDao:KullaniciDao
): AndroidViewModel(application), CoroutineScope {...}
And here is my fragment that use this view model;
@AndroidEntryPoint
class ProfilIslemFragment:Fragment(), ProfilIslemFragmentClickListener {
private val viewModel: ProfilIslemViewModel by viewModels();
...
}
Here is the module that injected class;
@Module
@InstallIn(SingletonComponent::class)
object KutuphanemAppModule {
@Singleton
@Provides
fun provideKutuphanemDatabase
(@ApplicationContext context:Context) = Room.databaseBuilder(
context,
KutuphanemDatabase::class.java,
KUTUPHANEM_DB_NAME
).build();
@Singleton
@Provides
fun provideRetrofit(client: OkHttpClient):Retrofit =
Retrofit.Builder()
.baseUrl(API_URL)
.addConverterFactory(ScalarsConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
@Singleton
@Provides
fun provideHttpClient(customSharedPreferences: CustomSharedPreferences):OkHttpClient{
return OkHttpClient.Builder().addInterceptor(object:Interceptor{
override fun intercept(chain: Interceptor.Chain): Response {
val request:Request = chain.request().newBuilder().addHeader("Authorization",
"Bearer "+customSharedPreferences.getStringFromSharedPreferences(APP_TOKEN_KEY).trim()).build();
return chain.proceed(request);
}
}).build();
}
@Singleton
@Provides
fun provideParametreDao(database: KutuphanemDatabase) = database.getParametreDao();
@Singleton
@Provides
fun provideParametreApi(retrofit: Retrofit):IParametreService = retrofit.create(IParametreService::class.java);
@Singleton
@Provides
fun provideKullaniciApi(retrofit: Retrofit):KullaniciService = retrofit.create(KullaniciService::class.java);
@Singleton
@Provides
fun provideKitapApi(retrofit: Retrofit):IKitapService = retrofit.create(IKitapService::class.java);
@Singleton
@Provides
fun provideKullaniciDao(database: KutuphanemDatabase) = database.getKullaniciDao();
}
When I rotate the screen the inputs are losing. How to solve this problem?
