网上开源项目：https://github.com/beworker/pinned-section-listview，该项目用的是ArrayAdapter()..不太适合我，稍作修改，仿的微信界面
PinnedSectionListView修改了一行代码，不然会报错，代码如下
void createPinnedShadow(int position) {}》》
1. if (layoutParams == null) {
2. //layoutParams = (LayoutParams) generateDefaultLayoutParams();
3. new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
4. pinnedView.setLayoutParams(layoutParams);
5. }
效果图：
具体代码AdapterListView：
1. package pinneactivity.example.ui;

3. import java.util.ArrayList;

5. import pinneactivity.example.ui.PinnedSectionListView.PinnedSectionListAdapter;
