PresenterFactory

使用说明

   

该框架相对来说有一定局限性，但是胜在使用方便快捷，能再简洁程度上比dagger2上有较大的优势

   

首先定义一个BaseActivity，自定义泛型P

public abstract class BaseActivity<P extends BasePresenter> extends AppCompatActivity {

   protected P mPresenter;

   @Override
   public void onCreate(@Nullable Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(getLayoutId());
       _injectPresenter();
       initView();
   }

   protected abstract void initView() ;

   private void _injectPresenter() {
       //此处获取到PresenterFactiry生成的对象
       if (this.getClass().getGenericSuperclass() instanceof ParameterizedType
               &&((ParameterizedType) (this.getClass().getGenericSuperclass())).getActualTypeArguments().length>0){
           Class mPresenterClass = (Class) ((ParameterizedType) (this.getClass().getGenericSuperclass())).getActualTypeArguments()[0];
           mPresenter = CreatePresenterUtil.getInstance(mPresenterClass);
           mPresenter.setView(this);
       }
   }

   protected abstract int getLayoutId();
}

在Presenter中定义注解

@InstanceFactory
public class TextPresenter extends BasePresenter {
    public TextPresenter(){}
    public void text(String name){
        Log.d(TextPresenter.class.getName(),name);
    }
    @Override
    public void setView(BaseActivity view) {
    }
}

最后找到InstanceProcess JavaFile javaFile = JavaFile.builder("填入你自己需要在哪里生成代码的包名",tb.build()).build();

以后就不需要像dagger2一样每次都需要写那些烦人的配置了~_~
