android的mvp与传统的mvc的比较

昨天晚上看了下我的偶像鸿神的博客，他博客中有一篇Android的mvp与传统的mvc的比较，我阅读了一遍之后，整个人神清气爽，太棒了，不愧是我的鸿神，然后自己吧思路整理了下，通过自己的理解吧他写在自己的博客上，以便不时之需。

mvc是业务逻辑层，视图层，控制层。由于Android的layout的布局的原因，导致视图层也被放到了activity中，又由于activity本身承担着控制层的任务，这样一看来，就会导致activity中代码很臃肿，不便于管理。下面是我用他的例子敲的

public interface RequestBiz {//定义一个接口,public void requestData(RequestListener listener);}

import java.util.List;/** * 回调函数 * */public interface RequestListener {public void onsucess(List<String> data);

           public void foresult();}

//实现它的方法

public class RequestBizImp implements RequestBiz {@Overridepublic void requestData(final RequestListener listener) {new Thread(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubList<String> list = new ArrayList<String>();for (int i = 0; i < 10; i++) {String name = "刘备" + i;list.add(name);}if (list != null) {// 获取到的数据添加到回调函数中listener.onsucess(list);}else{

<span style="white-space:pre"></span>listener.<span style="font-family: Arial, Helvetica, sans-serif;">foresult();</span>}}).start();}}

//在MainActivity中

public class MainActivity extends ActivityOnItemClickListener {private ListView listview;private Handler handler = new Handler();@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);listview = (ListView) findViewById(R.id.listview);// mvcģʽ mvc();}private void mvc() {RequestBiz biz = new RequestBizImp();biz.requestData(new RequestListener() {@Overridepublic void onsucess(final List<String> data) {// TODO Auto-generated method stubhandler.post(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(),android.R.layout.simple_list_item_1, data);listview.setAdapter(adapter);}});}

                           @Override<span style="white-space:pre"></span>public void foresult() {<span style="white-space:pre"></span>// TODO Auto-generated method stub<span style="white-space:pre"></span>System.out.println("数据为空");<span style="white-space:pre"></span>}});}

//mvp的模式

此图在鸿神博客中截取出来的。便于我以后参加的理解。

有图的话我就无需废话了，直接上代码

activity管理view

public interface Myview {// mvp是activity控制viewpublic void listData(List<String> list);}

public class Persten {private RequestBiz biz;private Myview myview;private Handler handler;public Persten(Myview myview) {// 初始化this.myview = myview;// 实现接口biz = new RequestBizImp();handler = new Handler(Looper.getMainLooper());}// 初始化数据public void onResume() {biz.requestData(new RequestListener() {@Overridepublic void onsucess(final List<String> data) {// TODO Auto-generated method stubhandler.post(new Runnable() {@Overridepublic void run() {myview.listData(data);}});}});}public void getPostion(int postion) {Toast.makeText(MyAppliction.getContext(), "第" + postion + "项", 0).show();}

public class MainActivity extends Activity implements Myview,OnItemClickListener {private ListView listview;...............private Persten persten;

persten = new Persten(this);<span style="white-space:pre"></span>listview.setOnItemClickListener(this);

@Override<span style="white-space:pre"></span>protected void onResume() {<span style="white-space:pre"></span>// TODO Auto-generated method stub<span style="white-space:pre"></span>super.onResume();<span style="white-space:pre"></span>// 初始化数据<span style="white-space:pre"></span>persten.onResume();<span style="white-space:pre"></span>}

@Override<span style="white-space:pre"></span>public void listData(List<String> list) {<span style="white-space:pre"></span>ArrayAdapter<String> adapter = new ArrayAdapter<String>(<span style="white-space:pre"></span>getApplicationContext(), android.R.layout.simple_list_item_1,<span style="white-space:pre"></span>list);<span style="white-space:pre"></span>listview.setAdapter(adapter);<span style="white-space:pre"></span>}<span style="white-space:pre"></span>@Override<span style="white-space:pre"></span>public void onItemClick(AdapterView<?> adapterView, View view, int postion,<span style="white-space:pre"></span>long l) {<span style="white-space:pre"></span>// TODO Auto-generated method stub<span style="white-space:pre"></span>persten.getPostion(postion);<span style="white-space:pre"></span>}
