在给ExpandableListView添加ContextMenu时，有时需要区分是group触发的长按还是child出发的长按，通过onCreateContextMenu的ContextMenuInfo参数可以具体判断出，具体代码：

public void onCreateContextMenu(ContextMenu menu, View view, ContextMenuInfo menuInfo) {ExpandableListContextMenuInfo adapterContextMenuInfo = (ExpandableListContextMenuInfo) menuInfo;View targetView = adapterContextMenuInfo.targetView;Object obj = targetView.getTag();// group的长按事件时if (obj != null && Constants.GROUP_VIEW.equals(obj.toString())) {menu.add(0, 0, 0, "delete");}}
