Dagger2 - How to use @Named with @BindsInstance

由 六眼飞鱼酱① 提交于 2020-07-21 07:30:28
问题 How is @Named used with @BindsInstance? I have the this component interface AppComponent : AndroidInjector<MyApplication>{ @Component.Builder abstract class Builder : AndroidInjector.Builder<MyApplication>() { @BindsInstance abstract fun preferenceName( @Named("PreferenceName") name : String ) : Builder } } and trying to inject in MyApplication @Inject @Named("PreferenceName") lateinit var prefName : String But it fails with MissingBinding for String. I could resolve this with a module

问题 I am facing an issue while implementing MultiBinding using dagger 2.2. I am using dagger with MVVM architecture. I have injected the ViewModelProvideFactory constructor and binds the dependency from module. I have followed the tutorial of Mitch from youtube https://www.youtube.com/watch?v=DToD1W9WdsE&list=PLgCYzUzKIBE8AOAspC3DHoBNZIBHbIOsC&index=13 I have searched on these links for the solutions but still facing the same issue.

问题 I am new to dagger, I have defined my application component like this @Singleton @Component(modules = {ApplicationModule.class}) public interface ApplicationComponent { void inject(BaseActivity activity); Context context(); } This is my ApplicationModule @Module public class ApplicationModule { public TipoApplication application; public ApplicationModule(TipoApplication application) { this.application = application; } @Singleton @Provides public Context provideContext(){return application

问题 I have the presenter class PhonePresenter @Inject constructor( private val preference: DataPreference, private val ioScheduler: Scheduler = Schedulers.io()) ioScheduler is a default parameter. I want to inject only preference: DataPreference . Now I have the exception [dagger.android.AndroidInjector.inject(T)] io.reactivex.Scheduler cannot be provided without an @Provides-annotated method. Is there any way to define parameters which I want to inject in a constructor? 回答1: Make inject

问题 lets say I have: public interface Shape {} public class Rectangle implements Shape { } public class Circle implements Shape { } and I have a ApplicationModule which needs to provides instances for both Rec and Circle : @Module public class ApplicationModule { private Shape rec; private Shape circle; public ApplicationModule() { rec = new Rectangle(); circle= new Circle (); } @Provides public Shape provideRectangle() { return rec ; } @Provides public Shape provideCircle() { return circle; } }

2020年Android面试题含答案 Android 2020年经典面试题 链接到 1.跨进程通信的几种方式 Intent,比如拨打电话 ContentProvider数据库存储数据 Broadcast广播通信 AIDL通信，通过接口共享数据 2.wait和 sleep 的区别 wait是Object的方法，wait是对象锁，锁定方法不让继续执行，当执行notify方法后就会继续执行，sleep 是Thread的方法，sleep 是使线程睡眠，让出cpu，结束后自动继续执行 3.String,StringBuffer,StringBuilder的区别 String不可改变对象，一旦创建就不能修改 String str="aaa"; str="bbb"; 以上代码虽然改变了str，但是执行过程是回收str，把值赋给一个新的str StringBuffer创建之后，可以去修改 StringBuilder也可修改，执行效率高于StringBuffer，不安全 当字符赋值少使用String 字符赋值频繁使用StringBuilder 当多个线程同步操作数据，使用StringBuffer 4.View和SurfaceView的区别 View基于主线程刷新UI，SurfaceView子线程又可以刷新UI 5.View的绘制原理 View为所有图形控件的基类，View的绘制由3个函数完成
