API 11日之前MultiChoiceMode [英] MultiChoiceMode before API 11

问题描述

我实现ActionMode在我的Andr​​oid应用程序与ActionBarSherlock。 有了ABS就可以API 11，但最简单的方式与以往建立一个ActionMode： listView.setMultiChoiceModeListener（新MultiChoiceModeListener（）... 是不是应用程序的API 11日之前。 有没有人API 11日之前建立一个操作模式的上下文菜单的好办法？ 我想打一个长按一个列表项，并开始在其中我可以点击多个项目的ActionMode。在一个简单的点击我显示列表项的细节部位。 我用的是 registerForContext（）的方法，但这样做一个简单的和长期的点击。

i implement the ActionMode in my Android App with ActionBarSherlock. With ABS it is possible to build a ActionMode before API 11 but the easy way with: listView.setMultiChoiceModeListener( new MultiChoiceModeListener() ... is not for app before API 11. Has anybody a good way to build a Action Mode Context Menu before API 11? I want to make a long click on a List Item and start the ActionMode in which i can click multiple items. On a simple click i show a detail site of the list item. I use the registerForContext() method but this make a simple and long click.

有没有人一个很好的提示我。

Has anybody a good tip for me.

修改
我的问题的解决方案是以下几点：在长期的项目点击我主动的操作模式，并保存在一个变量。在项目上单击的方法我实现了if-else语句：

EDIT
The solution for my question was following: On a long item click i active the action mode and save this in a variable. In the on item click method i implement a if-else statement with:

if( actionMode == null )
{
   // open new activity or update second fragment
   showDetails( itemPosition );
}
else
{
   // update ui or close CAB if no item selected
   showCAB( itemPosition );
}

该方法showCAB（位置）更新则selectedItem计数，突出项目的背景等。

The method showCAB( position ) update the selectedItem count, highlight item background and so on.

推荐答案

好吧，我只是今天的表现，这要归功于该网站：<一href="http://www.miximum.fr/tutos/849-porting-the-contextual-anction-mode-for-$p$p-honeycomb-android-apps">http://www.miximum.fr/tutos/849-porting-the-contextual-anction-mode-for-$p$p-honeycomb-android-apps

Alright, I just did that today, thanks to that site : http://www.miximum.fr/tutos/849-porting-the-contextual-anction-mode-for-pre-honeycomb-android-apps

基本上，你只需要设置你的ListView ChoiceMode到 ListView.CHOICE_MODE_MULTIPLE ，设置 onItemClickListener 那会检查什么项目上的ListView检查，并创建一个私有类实现 ActionMode.Callback 将管理上下文动作条。

Basically, you just need to set your ListView ChoiceMode to ListView.CHOICE_MODE_MULTIPLE, to set a onItemClickListener that would check what items are checked on the ListView and to create a private class implementing ActionMode.Callback that will manage the contextual ActionBar.
