推荐答案
这似乎是ActionBarSherlock不提供动画刷新菜单项具体方法。
It seems like ActionBarSherlock doesn't provide specific method to animate a refresh MenuItem.
你可以(通过使用经典的Android API)什么是使用 setActionView(INT渣油)
方法,并给出了一个布局ID与进度在里面。
What you can do (by using classic android API) is to use the setActionView(int resId)
method and give the id of a layout with a ProgressBar in it.
在你的刷新操作的开始就叫:
At the beginning of your refresh action just call :
item.setActionView(R.layout.refresh_menuitem);
当你刷新动作完成的呼叫:
And when your refresh action is finished call :
item.setActionView(null);
下面是一个什么样的布局文件样本的 refresh_menuitem.xml 可以有:
Here is a sample of what your layout file refresh_menuitem.xml can have :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:addStatesFromChildren="true"
android:focusable="true"
android:paddingLeft="4dp"
android:paddingRight="4dp"
android:gravity="center"
style="?attr/actionButtonStyle">
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
style="@android:style/Widget.ProgressBar.Small"/>
</LinearLayout>
