使用Dagger 2在activity和fragment中注入相同的类对象

implementation 'com.google.dagger:dagger:2.x'
annotationProcessor 'com.google.dagger:dagger-compiler:2.x'

public class MyClass {
    // 类的成员和方法
}

@Module
public class MyModule {
    @Provides
    public MyClass provideMyClass() {
        return new MyClass();
    }
}

@Component(modules = {MyModule.class})
public interface MyComponent {
    void inject(MyActivity activity);
    void inject(MyFragment fragment);
}

public class MyActivity extends AppCompatActivity {
    @Inject
    MyClass myClass;

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

        // 创建依赖注入组件
        MyComponent myComponent = DaggerMyComponent.builder()
                .myModule(new MyModule())
                .build();

        // 注入MyClass对象
        myComponent.inject(this);

        // 使用myClass对象
        // ...
    }
}
