MVP的实现，后续更新mvp和databinding结合

上图是界面和运行效果，mvp的结构图如下：

presenter类主要处理业务逻辑，view通过接口来和presenter交互减少耦合度，mode主要是存储数据和提供数据。

—–presenter—–
presenter代码

/** * 业务逻辑顶层父类 * Created by Administrator on 2017/9/2. */ public class BasePresenter {     Context mContext;   public void onAttached(Context mContext) {        this.mContext = mContext;    }    public void onCreat() {    }    public void onPause() {    }    public void onResume() {    }    public void onDestory() {        System.out.println("=test=BasePresenter=onDestory");        if (mContext != null) {            mContext = null;        }    }}** * mainActivity的逻辑处理类 * Created by Administrator on 2017/9/2. */ public class MainViewPresenter extends BasePresenter implements HttpUtil.HttpResponse {    //创建构造函数，要求是实现了mainViewInterface的子类    //view和presenter的对接扣    String netUrl = "http://tcc.taobao.com/cc/json/mobile_tel_segment.htm";    public MainView mainView;    public PhoneInfo phoneInfo;     public MainViewPresenter(MainView mainView) {        this.mainView = mainView;    }    //逻辑处理，获取数据，点击就事件等    //获取网络数据，传入参数    public void fetchDataFromNet(String phoneNumber) {        //校验或者包装参数        if (phoneNumber.length() != 11) {            mainView.showToast("请输入正确手机号");            return;        }        mainView.showLoading();        //下面是okhhtp开始请求数据        HttpUtil httpUtil = new HttpUtil();        HashMap<String, String> map = new HashMap<>();        map.put("tel", phoneNumber);        httpUtil.sendHttpGet(map, netUrl);        httpUtil.setHttpResponse(this);    }    @Override    public void onFailed(String failure) {        mainView.showToast(failure);        mainView.hidenLoading();    }    @Override    public void onSuccess(String result) {        mainView.hidenLoading();        //数据解析也在presenter        try {            result=result.substring(result.indexOf("{"),result.length());            phoneInfo=new Gson().fromJson(result,PhoneInfo.class);        } catch (JsonSyntaxException e) {            e.printStackTrace();            mainView.showToast("返回结果解析异常");        }        //刷新UI        mainView.updataCurrentView();    }    public PhoneInfo getPhoneInfo(){        return phoneInfo;    }}

—–view—–
view层

/** * view的顶级父类，给p提供交互 * Created by Administrator on 2017/9/2. */public interface BaseView {    void showLoading();    void hidenLoading();}/** * mainView的接口，v和p都是通过infterface来交互解耦 * Created by Administrator on 2017/9/2. */public interface MainView  extends BaseView {    //view的方法太多，抽取父类，都是给pren层的    void showToast(String msg);    void updataCurrentView();//可以传入参数的}-----activity的代码-----public class MainActivity extends AppCompatActivity implements View.OnClickListener,MainView {    private MainViewPresenter mainViewPresenter;    private ActivityMainBinding mainBinding;    private ProgressDialog dialog;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        mainBinding = DataBindingUtil.setContentView(this, R.layout.activity_main);        //将整个view层都传出去        mainBinding.btnQuery.setOnClickListener(this);        mainViewPresenter = new MainViewPresenter(this);        mainViewPresenter.onAttached(this);    }    @Override    protected void onDestroy() {        super.onDestroy();        mainViewPresenter.onDestory();    }    @Override    public void onClick(View v) {        switch (v.getId()) {            case R.id.btn_query:                String phone=mainBinding.editPhone.getText().toString().trim();                mainViewPresenter.fetchDataFromNet(phone);                break;        }    }    @Override    public void showLoading() {        dialog = new ProgressDialog(this);        dialog.show();    }    @Override    public void hidenLoading() {        if (dialog!=null&&dialog.isShowing()) {            dialog.dismiss();        }    }    @Override    public void showToast(String msg) {        Toast.makeText(this,msg,Toast.LENGTH_SHORT).show();    }    @Override    public void updataCurrentView() {        PhoneInfo phoneInfo = mainViewPresenter.getPhoneInfo();        mainBinding.tvPhone.setText("手机号："+phoneInfo.getTelString());        mainBinding.tvProvince.setText("省份："+phoneInfo.getProvince());        mainBinding.tvSeller.setText("运营商："+phoneInfo.getCatName());        mainBinding.tvSeller2.setText("归属运营商:"+phoneInfo.getCarrier());    }}

最后是通用的http请求类

/** * 定义通用http请求网络类 * Created by Administrator on 2017/9/2. */public class HttpUtil {    private final OkHttpClient client = new OkHttpClient();    private String url;    private Map<String, String> params;    private Handler handler = new Handler(Looper.getMainLooper());    public void setHttpResponse(HttpResponse httpResponse) {        this.httpResponse = httpResponse;    }    //设置接口将结果传送回去    private HttpResponse httpResponse;    public interface HttpResponse {        //失败请求回调        void onFailed(String failure);        //成功请求回调        void onSuccess(String result);    }    /**     * Post请求     */    public void sendHttpPost(Map<String, String> param, String netUrl) {        doHttpNet(param, netUrl, true);    }    /**     * Get请求     */    public void sendHttpGet(Map<String, String> param, String netUrl) {        doHttpNet(param, netUrl, false);    }    private void doHttpNet(Map<String, String> param, String netUrl, boolean isPost) {        url = netUrl;        params = param;        runHttp(isPost);    }    private void runHttp(boolean isPost) {        Request request = creatRequest(isPost);        //请求头弄完在 直接发送请求        client.newCall(request).enqueue(new Callback() {            @Override            public void onFailure(Call call, final IOException e) {                if (httpResponse != null) {                    //回调是在子线程，而UI是在主线程                    handler.post(new Runnable() {                        @Override                        public void run() {                            httpResponse.onFailed(e.toString());                        }                    });                }            }            @Override            public void onResponse(Call call, final Response response) throws IOException {                if (httpResponse != null) {                    final String result = response.body().string();                    handler.post(new Runnable() {                        @Override                        public void run() {                            if (response.isSuccessful()) {                                //请求成功                                httpResponse.onSuccess(result);                            }else{                                httpResponse.onFailed(result);                            }                        }                    });                }            }        });    }    /**     * 创建requst     */    private Request creatRequest(boolean isPost) {        Request request;        if (isPost) {            //Post请求            MultipartBody.Builder multipartBody = new MultipartBody.Builder();            multipartBody.setType(MultipartBody.FORM);//表单形式提交请求            //遍历map获取参数            Iterator<Map.Entry<String, String>> iterator = params.entrySet().iterator();            while (iterator.hasNext()) {                Map.Entry<String, String> next = iterator.next();                multipartBody.addFormDataPart(next.getKey(), next.getValue());            }            //创建请求            request = new Request.Builder().url(url).post(multipartBody.build()).build();        } else {            //Get请求,只是拼接参数和网址            Iterator<Map.Entry<String, String>> iterator = params.entrySet().iterator();            StringBuilder strBuilder = new StringBuilder(url + "?");//这里先加进去            while (iterator.hasNext()) {                Map.Entry<String, String> next = iterator.next();                strBuilder.append(next.getKey() + "=" + next.getValue() + "&");            }            //最后祛除对于的一个“&”符号            String str = strBuilder.toString().substring(0, strBuilder.length() - 1);            request = new Request.Builder().url(str).build();            System.out.println("==test==" + str);        }        return request;    }}
