问题描述
我使用的动作条。我想有一个刷新进度微调的标题栏，如果我将它设置为纺纱 - 否则隐藏它。这是可能的：
I'm using the ActionBar. I'd like to have a refresh progress spinner on the titlebar, if I set it to spinning - otherwise hide it. Is that possible?:
// My menu has a refresh item, but it shouldn't be visible on the
// actionbar unless it's spinning.
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/menu_refresh"
android:title="@string/refresh"
android:icon="@drawable/ic_action_refresh" />
</menu>
...
// When I need to show some work being done on my activity,
// can I somehow now make the spinner associated with the
// refresh item become visible on the action bar?
getActionBarHelper().setRefreshActionItemState(true);
我不希望它在动作条，除非它是进行中/旋转着。
I don't want it on the ActionBar unless it's "in progress" / spinning.
感谢

这是从ActionbarSherlock（谷歌，如果你还没有遇到过，可以让动作条在pre蜂窝载体）
This is from ActionbarSherlock (Google that if you've not come across it, allows actionbar support in pre honeycomb)
在主要活动的onCreate
In onCreate of main activity
// This has to be called before setContentView and you must use the
// class in android.support.v4.view and NOT android.view
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
要显示操作栏/隐藏进度。与actionbarsherlock请注意，你必须使用boolean.TRUE / FALSE，不只是真/假.........
To show/hide progress in action bar. Notice with actionbarsherlock you must use boolean.TRUE/FALSE, not just true/false.........
if (getSupportLoaderManager().hasRunningLoaders()) {
setProgressBarIndeterminateVisibility(Boolean.TRUE);
} else {
setProgressBarIndeterminateVisibility(Boolean.FALSE);
}
