实例

1.LoginContractor 将三个接口合并为一个

public interface LoginContract {
    interface Model {
        void login(String name, String psw, LoginPresenter loginPresenter);
    }

    interface View {
        void shouToast(String msg);

        void onSuccess();

        String getName();

        String getPassword();

    }

    interface Presenter {
        void onSuccess();//登陆成功

        void onFailure(String msg);//登陆失败

    }
}

2.LoginModel 对数据进行校验 进行业务逻辑判断

public class LoginModel implements LoginContract.Model {
    @Override
    public void login(String name, String psw, LoginPresenter loginPresenter) {
        if (name.equals("123") && psw.equals("123")) {
            loginPresenter.onSuccess();
        } else {
            loginPresenter.onFailure("用户名或密码错误");
        }
    }
}

3.View 实现数据的获取

public class MainActivity extends AppCompatActivity implements LoginContract.View{

    EditText name;
    EditText password;
    Button login;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
    }

    private void initView() {
        name = findViewById(R.id.name);
        password=findViewById(R.id.password);
        login=findViewById(R.id.login);
        login.setOnClickListener(v -> {
            LoginPresenter presenter = new LoginPresenter();
            presenter.setView(this);
            LoginContract.Model model = new LoginModel();
            model.login(getName(), getPassword(), presenter);
        });
    }

    @Override
    public void shouToast(String msg) {
        Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onSuccess() {
        Toast.makeText(this, "登录成功", Toast.LENGTH_SHORT).show();
    }

    @Override
    public String getName() {
        return name.getText().toString();
    }

    @Override
    public String getPassword() {
        return password.getText().toString();
    }
}

4 LoginPresenter 持有view

public class LoginPresenter implements LoginContract.Presenter {
    LoginModel model;
    LoginContract.View view;

    public void setView(LoginContract.View view) {
        this.view = view;
    }

    @Override
    public void onSuccess() {
        view.onSuccess();
    }

    @Override
    public void onFailure(String msg) {
        view.shouToast(msg);
    }
}
