android使用inject需要注意的地方

1.viewmodel里面添加注解

@Inject

FavoritesDBManager mFavoritesDBManager;

2.Component里面添加dependencies = AppComponent.class

@Component(modules = CoinSearchModule.class,dependencies = AppComponent.class)

3.activity里面添加.appComponent(ComponentHolder.getComponent())

@Override

protected void inject() {

ARouter.getInstance().inject(this);

CoinDetailComponent component = DaggerCoinDetailComponent.builder()

.coinDetailModule(new CoinDetailModule(this))

.appComponent(ComponentHolder.getComponent())

.build();

component.injectActivity(this);

component.injectViewModel(mViewModel);

mBinding.setActivity(this);

mBinding.setViewmodel(mViewModel);
