千磨万击还坚劲，任尔东西南北风。这篇文章主要讲述Android MVP模式实现组件和业务逻辑分离相关的知识，希望能为你提供帮助。
【Android MVP模式实现组件和业务逻辑分离】1，Activity代码展示，只需要一下3行重要代码即可完成任何复杂的逻辑
/**
* 登录界面
*
* @author lipanquan
*/
public class LoginActivity extends MVPBaseActivity {
@Override
protected void setTitle() {
getAOP().setTitle();
}
@Override
protected ActivityPresenter initAOP() {
return new LoginActivityPresenter(this);
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
return getAOP().onKeyUp(keyCode, event);
}
}
2，登录界面的逻辑控制代码
