Android(安卓)MVP设计模式登录具体实现Material Design风格

首先讲讲什么是MVP设计模式：

Model 依然是业务逻辑和实体模型
View 对应于Activity，负责View的绘制以及与用户交互
Presenter 负责完成View于Model间的交互

然后看看具体分包图

运行截图：

具体代码如下：

- M层

实体类UserBean.class

public class UserBean {    public String username;    public String password;}

登录回调接口

public interface OnLoginListener {    void getDataSuccess(UserBean userBean);    void getDataFail(String msg);}

IUserBiz.class

public interface IUserBiz {    void login(String username,String password,OnLoginListener onLoginListener);}

UserBiz.class

public class UserBiz implements IUserBiz {    @Override    public void login(final String username, final String password, final OnLoginListener onLoginListener) {        new Thread(){            @Override            public void run() {                try {                    Thread.sleep(2000);                } catch (InterruptedException e) {                    e.printStackTrace();                }                if("kxx".equals(username) && "123".equals(password)){                    UserBean userBean = new UserBean();                    userBean.username = username;                    userBean.password = password;                    onLoginListener.getDataSuccess(userBean);                }else {                    onLoginListener.getDataFail("用户名或密码错误");                }            }        }.start();    }}

- V层

ILoginView.class

public interface ILoginView {    String getUserName();    String getPassWord();    void showLoading();    void hideLoading();    void showSuccessData(UserBean userBean);    void showFailData(String msg);    void clearData();}

登录界面 LoginView.class

public class LoginView extends AppCompatActivity implements ILoginView,View.OnClickListener {    private TextInputLayout tl_name;    private TextInputEditText et_name;    private TextInputEditText et_pwd;    private Button bt_login;    private Button bt_clear;    private ProgressDialog dialog;    private UserPresenter userPresenter;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.login);        initView();    }    private void initView() {        tl_name = (TextInputLayout) findViewById(R.id.tl_name);        et_name = (TextInputEditText) findViewById(R.id.et_name);        et_pwd = (TextInputEditText) findViewById(R.id.et_pwd);        bt_clear = (Button) findViewById(R.id.bt_clear);        bt_login = (Button) findViewById(R.id.bt_login);        bt_login.setOnClickListener(this);        bt_clear.setOnClickListener(this);        userPresenter = new UserPresenter(this);    }    @Override    public void onClick(View v) {        switch (v.getId()){            case R.id.bt_login://                et_name.setError("格式不正确");//                tl_name.setError("格式不正确");                userPresenter.login();                break;            case R.id.bt_clear:                userPresenter.clear();                break;        }    }    @Override    public String getUserName() {        return et_name.getText().toString();    }    @Override    public String getPassWord() {        return et_pwd.getText().toString();    }    @Override    public void showLoading() {        dialog = new ProgressDialog(this);        dialog.setMessage("Loading...");        dialog.show();    }    @Override    public void hideLoading() {        if(dialog != null && dialog.isShowing()){            dialog.dismiss();        }    }    @Override    public void showSuccessData(UserBean userBean) {        Toast.makeText(this, "@@@"+userBean.username+"---"+userBean.password, Toast.LENGTH_SHORT).show();    }    @Override    public void showFailData(String msg) {        Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();    }    @Override    public void clearData() {        et_name.setText("");        et_pwd.setText("");    }

- P层

UserPresenter.class

public class UserPresenter {    private LoginView loginView;    private UserBiz userBiz;    Handler handler = new Handler();    public UserPresenter(LoginView loginView) {        this.loginView = loginView;        userBiz = new UserBiz();    }    public void login() {        loginView.showLoading();        userBiz.login(loginView.getUserName(), loginView.getPassWord(), new OnLoginListener() {            @Override            public void getDataSuccess(final UserBean userBean) {                handler.post(new Runnable() {                    @Override                    public void run() {                        loginView.showSuccessData(userBean);                        loginView.hideLoading();                    }                });            }            @Override            public void getDataFail(final String msg) {                handler.post(new Runnable() {                    @Override                    public void run() {                        loginView.showFailData(msg);                        loginView.hideLoading();                    }                });            }        });    }    public void clear() {        loginView.clearData();    }}
