Rxandroid与MVP的结合(demo)

这是一个简单的demo(登陆返回)，保存下来,以后时不时的看看而已
MVP分为M层 V层 P层
M->biz,登陆逻辑，登陆返回
V->一个接口,反馈给MainActivity
P->连接biz与View的纽带，请求biz获取数据,使用V更改界面

先写实体User
User.class

public class User {    public String name;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}

登陆成功失败的接口
OnGetDataListener

/** * 登陆成功失败的回调 */public interface OnGetDataListener<T> {    void success(T response); // 网络操作成功    void fail(T response, String msg); // 网络操作失败}

登陆逻辑
LoginBiz

public class LoginBiz {    public void doLogin(final OnGetDataListener<User> listener,final User user ){        Observable.create(new Observable.OnSubscribe<User>() {            @Override            public void call(Subscriber<? super User> subscriber) {                try {                    Thread.sleep(3000);                } catch (InterruptedException e) {                    e.printStackTrace();                }                subscriber.onNext(user);            }        }).subscribeOn(Schedulers.newThread())                .observeOn(AndroidSchedulers.mainThread())                .subscribe(new Subscriber<User>() {                    @Override                    public void onCompleted() {                    }                    @Override                    public void onError(Throwable e) {                    }                    @Override                    public void onNext(User user) {                        if (user!=null)                            listener.success(user);                        else                            listener.fail(user,"error");                    }                });    }}

View层
ILoginView

/** * 登录界面，是一个接口，如：展示进度条、隐藏进度条、展示数据等 */public interface ILoginView {    void showView(String userName);    void showLoadding();    void hideLoadding();}

P层
LoginPresenter

/** * Created by pailiao on 2016/7/27. * 连接view与biz的纽带 * 请求logbiz获取数据,使用ILoginView层更新数据 */public class LoginPresenter {    private ILoginView loginView;    private LoginBiz loginBiz;    public LoginPresenter(ILoginView loginView) {        this.loginView = loginView;        this.loginBiz = new LoginBiz();    }    public void doLogin(String userName){        loginView.showLoadding(); // 展示加载条        User user = new User();        user.name = userName;        loginBiz.doLogin(new OnGetDataListener<User>() {            @Override            public void success(User response) {                loginView.hideLoadding(); // 隐藏加载条                loginView.showView(response.name); // 展示数据            }            @Override            public void fail(User response, String msg) {                loginView.hideLoadding();                loginView.showView(msg);            }        },user);    }}

MainActivity的xml文件

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin">    <TextView        android:id="@+id/textView"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="用户名" />    <EditText        android:id="@+id/editText"        android:layout_width="match_parent"        android:layout_height="wrap_content" />    <Button        android:id="@+id/button"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="DO" />    <ProgressBar        android:id="@+id/progressBar"        style="?android:attr/progressBarStyleLarge"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_horizontal"        android:visibility="gone" /></LinearLayout>

MainActivity.class

public class MainActivity extends Activity implements ILoginView {    private String TAG = MainActivity.class.getSimpleName();    private EditText editText;    private TextView textView;    private Button button;    private ProgressBar progressBar;    private LoginPresenter loginPresenter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initUI();        loginPresenter=new LoginPresenter(this);        button=(Button) findViewById(R.id.button);        button.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                String userName = editText.getText().toString();                loginPresenter.doLogin(userName);            }        });    }    private void initUI() {        editText = (EditText) findViewById(R.id.editText);        textView = (TextView) findViewById(R.id.textView);        progressBar = (ProgressBar) findViewById(R.id.progressBar);    }    @Override    public void showView(String userName) {        textView.setText(userName);    }    @Override    public void showLoadding() {        progressBar.setVisibility(View.VISIBLE);    }    @Override    public void hideLoadding() {        progressBar.setVisibility(View.GONE);    }}

记性不好,特此记录
