Android MVP架构简单封装

最近在研究MVP和MVVM架构模式，看了看觉得还是MVP好做点，特意查查资料，做了下简单的封装。先看一下自己封装项目的基本库结构。



来看看源码吧

BasePresenter.java

public abstract class BasePresenter<T> {

protected Reference<T> mViewRef;//View接口类型的弱引用

public void attachView(T view){

mViewRef=new WeakReference<T>(view);//建立关系

}

protected T getView(){

return mViewRef.get();
}

public boolean isViewAttached(){

return mViewRef!=null&&mViewRef.get()!=null;
}

public void detachView(){

if (mViewRef!=null){

mViewRef.clear();
mViewRef=null;
}

}

}

BaseActivity.java

public abstract class BaseActivity<V,T extends BasePresenter<V>> extends AppCompatActivity {

protected T mPresenter;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

mPresenter=createPresenter();//创建presenter
mPresenter.attachView((V)this);

initVariables();
initViews(savedInstanceState);
loadData();
}

@Override
protected void onDestroy() {
super.onDestroy();
mPresenter.detachView();
}

//初始化变量，接受其他页面传递的参数
protected abstract void initVariables();
//初始化布局文件、控件
protected abstract void initViews(Bundle savedInstanceState);
//加载数据
protected abstract void loadData();

protected abstract T createPresenter();
}

BaseFragment.java

public abstract class BaseFragment<V,T extends BasePresenter<V>> extends Fragment {

protected T mPresenter;

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mPresenter=createPresenter();//创建presenter
mPresenter.attachView((V) this);
initVariables();
}

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

return inflater.inflate(getContentId(),container,false);
}

@Override
public void onResume() {
super.onResume();
loadData();

}

@Override
public void onDestroy() {
super.onDestroy();
mPresenter.detachView();
}

protected abstract void initVariables();
protected abstract int getContentId();
protected abstract void loadData();
protected abstract T createPresenter();

}

数据监听接口

DataRequestListener.java

public interface DataRequestListener<T> {

void success(T data);
void fail();

}

特此记录特供大家参考，仅仅是简单的封装，可以根据自己的项目自己再次封装重构，自己也算做个笔记！~

如果觉得有用，打赏个呗！
