抽取基类

Presenter基类

public class BasePresenter<V> {

    // V 相当于V的接口
    public V view;


    /**
     *  Presenter 持有View 的接口
     * @param v
     */
    public void attach(V v){
        this.view = v ;
    }

    /**
     * Presenter 释放持有View的接口， 防止内存泄漏
     */
    public void detach(){
        this.view = null;
    }

Activity基类

public abstract class BaseMvpActivity<V,T extends BasePresenter<V>> extends Activity {
//              class BaseMvpActivity<LoginView,LoginPresenter extends BasePresneter<LoginView>> extends Activity {


    public T t;


    public abstract T initPresenter();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        t = initPresenter();

    }




    @Override
    protected void onResume() {
        super.onResume();
        t.attach((V) this);
    }


    @Override
    protected void onDestroy() {
        super.onDestroy();
        t.detach();
    }
}

主Activity

public class LoginActivity extends BaseMvpActivity<LoginView,LoginPresenter> implements LoginView {


    @Override
    public LoginPresenter initPresenter() {
        return new LoginPresenter();
    }


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login2);






        findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                t.login("muhanxi","password");


            }
        });

    }


    @Override
    public void success(Bean bean) {


        System.out.println("ok" + bean.toString());
    }


    @Override
    public void failure() {

    }
}
