使用Dagger2创建retrofit2时的动态设置

@Module
public class RetrofitModule {
    private String baseUrl;

    public RetrofitModule(String baseUrl) {
        this.baseUrl = baseUrl;
    }

    @Provides
    @Singleton
    Retrofit provideRetrofit() {
        return new Retrofit.Builder()
                .baseUrl(baseUrl)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
}

@Singleton
@Component(modules = RetrofitModule.class)
public interface RetrofitComponent {
    Retrofit getRetrofit();
}

public class MyActivity extends AppCompatActivity {
    @Inject
    Retrofit retrofit;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        DaggerRetrofitComponent.builder()
                .retrofitModule(new RetrofitModule("https://api.example.com"))
                .build()
                .inject(this);

        // 使用retrofit进行网络请求
        // ...
    }
}
