四：案例

• present 控制类

public class TestDemoContract {

    interface TestDemoView extends IView {

        void addSuccess();
    }


    interface TestDemoPresenter extends IPresenter<TestDemoView> {

        void getInfo(String aaa, String bbb, String ccc);

    }
}

*present类

public class TestDemoPresenter extends AbstractPresenter<TestDemoContract.TestDemoView> implements TestDemoContract.TestDemoPresenter {

 //private TestDemoContract.TestDemoView mView;

    public TestDemoPresenter(Context context) {
       super(context);
    }

     @Override
    public void getInfo(String aaa, String bbb, String ccc) {
       
           if (TextUtils.isEmpty(aaa)) {
                getView().showError("aaa不能为空"));
                return;
            mView.showLoading();
              getCompositeDisposable().add(NetworkManager.getInstance()
                .create(MoneyApi.class)
                .getInfo(aaa, bbb, ccc)
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Consumer<Response>() {
                    @Override
                    public void accept(Response response) throws Exception {
                         getView().hideLoading();
                        if (response.isSuccess()) {
                             getView().addSuccess();
                        } else {
                            ToastUtil.showToast(response.getMsg());
                        }
                    }
                }, new ResponseException() {
                    @Override
                    public void onError(ApiException e) {
                         getView().hideLoading();
                        ToastUtil.showToast(e.getShowMessage());
                    }
                }));
        }
    }
     @Override
    public void attach(TestDemoContract.TestDemoView view) {
        //this.mView = view;
        bindView(view);
    }

    @Override
    public void dettach() {
        //this.mView = null;
        destory();
    }
}

*Activity

public class TestDemoActivity extends BaseMvpActivity<TestDemoContract.TestDemoPresenter,
        TestDemoContract.TestDemoView>
        implements View.OnClickListener, TestDemoContract.TestDemoView {

 @Override
    protected int getLayout() {
        return R.layout.activity_test_demo;
    }

     @Override
    protected TestDemoContract.TestDemoPresenter initPreseter() {
        if (mPresenter == null) {
            mPresenter = new TestDemoPresenter(this);
        }
        return mPresenter;
    }

     @Override
    protected void initView() {
   
    }

      @Override
    protected void initListener() {
       
    }

     @Override
    protected void initData() {
       
    }

      @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.backImg:
                  finish();
                break;
            case R.id.btn_next_step:
                mPresenter.getInfo(aaa,bbb,ccc);
                break;
        }
    }

     @Override
    public void addSuccess() {
        //接口回调  做需要做的事情，需要参数的话 就在里面传递
    }

     @Override
    public void showLoading() {
        mLoading.setVisibility(View.VISIBLE);
    }

    @Override
    public void hideLoading() {
        mLoading.setVisibility(View.GONE);
    }

    @Override
    public void showError(String message) {
        ToastUtil.showToast(message);
    }
}
