之前学习了Pulltorefresh，pinnedheaderexpanablelistview 但是结合起来还是有点麻烦的。尤其是像QQ这种。他不是单纯的第一个当做分组。他是分组上面还有几个按钮，还有搜索框，同时可以滑动，而且还可以悬停。想了试了好几种方法，都有BUG。最后用的一种方法。
1. pulltorefresh用的android.v4里面自带的，好像知乎也是
2. 悬停和分组用的网上的，然后我把第一个分组的样式改成了自定义的menu菜单，并且清空了child.这样看上去就像一个自定义layout和listview一起滑动。
3. 下面是样式图
整个部分是可以滑动的。
下拉刷新之后 最上面会有一个彩色带。有点细。这是系统弄的效果
这是悬停效果，之前的自定义菜单被滑动上去了。
下面是核心代码，非常简洁

});
}
/**

private void initData() {
for(int i=0;i<5;i++){
groupData[i] = " group "+i;
}
for(int i=1;i<5;i++){
for(int j=0;j<10;j++){
childrenData[i][j] = "qq "+j;
}
}
//设置悬浮头部VIEW
explistview.setHeaderView(View.inflate(MainActivity.this,R.layout.group,
null));
adapter = new MainAdapter(childrenData, groupData, getApplicationContext(),explistview);
explistview.setAdapter(adapter);
explistview.setOnChildClickListener(new OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
Toast.makeText(MainActivity.this, "分组:"+groupData[groupPosition]+",好友:"+childrenData[groupPosition][childPosition], Toast.LENGTH_SHORT).show();
return false;
}
});
}
}
你需要做的就是设置监听器和传数据，记住数据第一组不会显示的，而且child必须为0个。
菜单样式和分组样式在这里getview设置。

是不是很少，需要自己改的代码就这两个文件。
