android 粗鲁简单仿美团/大众点评搜索方式，详细标注

转载请注明出处王亟亟的大牛之路

美团和大众点评的搜索和筛选栏，不能说好看（审美flag），但是满足了我们的搜索还筛选的需求，所以今天就实现了下这样的一个小Demo

项目结构：运行效果就是下图了，就不再截图了

初始化的样子：

具体实现就是起初3个LinearLayout，点击之后出现一个ListView然后会根据对这个LisvView的点击可能会再出现下一级别的子菜单。

废话不多说，直接上代码
MainActivity

public class MainActivity extends Activity implements OnClickListener,OnDismissListener{    private ImageView icon1, icon2, icon3;    private TextView fenlei, diqu, paixu;    private LinearLayout ll_top;    private LinearLayout ll_fenlei, ll_diqu, ll_paixu;    private ListView lv1, lv2,lv3, lv4;    private LinearLayout ll2;    private PopupWindow popLeft,popMid,popRight;    private List<father> fatlist;

一些比较重要的内容就这些了，子层级的item啊，father son的对象声明啊，看源码吧，只是用于填充数据的容器而已
