问题描述
我有一个ListFragment活动。
I have a ListFragment Activity.
我想要创建onItemClickedLong preSS的方法,从而当用户执行此操作。菜单弹出。我熟悉创建菜单。
I want to create a method for onItemClickedLongPress, so that when the user does this. a menu pops up. I am familiar with creating the menu.
所以,如果有人会请给我如何设置覆盖长preSS在ListFragment活动进一步的说明?
So if some one would please, give me further instructions on how to set Override the longpress in a ListFragment activity?
推荐答案
编辑:此示例演示如何显示的东西以外的其他系统菜单FX。 QuickAction从 https://github.com/lorensiuswlt/NewQuickAction
edit: this sample shows how to show something other then system menu fx. QuickAction from https://github.com/lorensiuswlt/NewQuickAction
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//.......
registerForContextMenu(getListView());
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
AdapterView.AdapterContextMenuInfo amenuInfo = (AdapterView.AdapterContextMenuInfo) menuInfo;
Object item = getListAdapter().getItem(amenuInfo.position);
//item could be Cursor/String/YourObject it depends on Adapter
//show popup fx. QuickAction from https://github.com/lorensiuswlt/NewQuickAction
QuickAction qa = new QuickAction(getActivity());
qa.setAnimStyle(QuickAction.ANIM_AUTO);
qa.show(amenuInfo.targetView);
}
编辑:这ansewer不好 ...为什么我这样做这样奇怪的方法?因为Eclipse的智能感知不propmt好 setOnLongClickListener
为的ListView
(因为的ListView
至少2 setOnLongClickListener
方法......一个来自查看
和第二从适配器视图
班)......最简单的方法就是让你的 ListFragment
实施 AdapterView.OnItemLongClickListener
然后在 onViewCreated
添加code getListView()setOnLongClickListener(本);
This ansewer is not good ... why i did this such strange method? because eclipse intellisense did not propmt "good" setOnLongClickListener
for ListView
(since ListView
has at least 2 setOnLongClickListener
methods ... one from View
and second from AdapterView
class) ... the easiest way is let your ListFragment
implement AdapterView.OnItemLongClickListener
and then in onViewCreated
add code getListView().setOnLongClickListener(this);
