android MVP设计模式的Demo（MV无P）

// 接口的定义 


public interface IView {

// 获取到输入的Spring
    String getInPutString();

// 将文字set进去
    void setResultString(String string);

}

public interface IPresenter {
    void search();
}


public interface IUserService {
    String search(int hashCode);
}

// 接口的动作实现类
public class Presenter implements IPresenter{

    private IView mView;

    public Presenter(IView view){
        mView = view;
    }

    @Override
    public void search() {
        // 开启界面loding
        String inputString = mView.getInPutString();
        if (TextUtils.isEmpty(inputString)){
            // 为空直接返回
            return;
        }

        int hashCode = inputString.hashCode();

        IUserService service = new UserService();

        String serviceResult = service.search(hashCode);

        String result = "Result:"+inputString+"---"+ serviceResult;
        // 关闭界面loding
        mView.setResultString(result);
    }

}



public class UserService implements IUserService{

    @Override
    public String search(int hashCode){
        return "User"+hashCode;
    }
}

// View层 实现View
public class MainActivity extends Activity implements IView {


    @BindView(R.id.text_result)
    TextView mResultText;

    @BindView(R.id.edit_query)
    EditText mInputText;

    private IPresenter mpresenter;

    @Override
    protected int getContentLayoutId() {
        return R.layout.activity_main;
    }

    @Override
    protected void initData() {
        super.initData();
        mpresenter = new Presenter(this);
    }

    @OnClick(R.id.btn_submit)
    void onSubmit() {
        mpresenter.search();
    }


    @Override
    public String getInPutString() {
        return mInputText.getText().toString();
    }

    @Override
    public void setResultString(String string) {
        mResultText.setText(string);
    }
}
