*我的应用程序中有一个导航抽屉。我按照以下脚本以编程方式添加了菜单项。我想将某些项目组合为可扩展列表视图，但我不确定如何去做。
$("#logOut").click(function(){
$.ajax({
url: '/logOut',
method: "POST"
});
});
我从string.xml private String[] mNavigationDrawerItemTitles;
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
Toolbar toolbar;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
ActionBarDrawerToggle mDrawerToggle;
SharedPreferences.Editor editor;
SharedPreferences pref;
ProgressDialog pd;
Token token = new Token();

答案 0 :(得分：0)
我会将DataModel[] drawerItem = new DataModel[7];列为清单。然后就像使用任何其他列表视图一样使用drawerItem.add("your new drawer item")和adapter.notifyDataSetChanged()。或者，您可以保持原样并向适配器添加方法以传入新数组并以此方式更新。
