BaseActivity抽取和点击条目展示电影的简介

题目要求

实现图1界面效果,用户下拉刷新,上拉加载,能够加载更多数据,图片处理框架进行缓存设置,向左侧拉,可以拉出侧拉菜单
点击图1影片的条目,可以跳转到图2的界面,这里图1要把条目对应的电影ID传到图2,图2拿到电影ID正常请求网络,会得到条目里电影的详细数据

提示:图1是一个Activity,图2也是一个Activity,要进行BaseActivity的抽取

效果图

界面1

BaseActivity抽取和点击条目展示电影的简介

界面2 BaseActivity抽取和点击条目展示电影的简介

技术选型

Imageloader
Pulltorefresh
HttpURLConnection
AsyncTask或者handler
drawlayout/slidingmenu
基类的抽取

接口(请求方式都是GET)

查询正在上映电影列表:

http://172.17.8.100/movieApi/movie/v1/findReleaseMovieList

BaseActivity抽取和点击条目展示电影的简介

根据电影ID查询电影信息:

baseActivity基类

public abstract class BaseActivity extends AppCompatActivity {
    @Override

        super.onCreate(savedInstanceState);
        //初始化布局
        setContentView(initContentView());
        //控件
        initView();
        //数据
        initData();
