解决方案

为了使进度条显示出来，您需要打开ActionBar.DISPLAY_SHOW_CUSTOM在ActionBar.displayOptions。

抓票据使用自定义动画的进度条。我觉得默认的Holo（正常大小）一个是一个合理的选择，但要达到这样的具体的一个，你要创建一个animationDrawable。

然后您可以通过动作条与getCustomView（）的自定义视图，找到你的ImageView，并启动动画。

It's not so much the action bar, as much as it is creating a custom progress bar that I need help with. I want to create one exactly like Catch Notes - https://ssl.gstatic.com/android/market/com.threebanana.notes/ss-480-0-9 https://market.android.com/details?id=com.threebanana.notes

I've tried multiple times in multiple different ways. I've looked at numerous tutorials including the Android Dev Guide. I'm pretty much angry at this point. Will someone offer me some help, please?

Right now, my Action Bar is calling a generic progress bar layout and that works fine.

switch (item.getItemId()) {
    case R.id.refresh:
        item.setActionView(R.layout.progress);
        return true;

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" android:weightSum="1">

<ProgressBar android:id="@+id/progress" 
style="?android:attr/progressBarStyleSmall"  
android:layout_width="wrap_content" 
android:layout_height="wrap_content">
</ProgressBar>

</LinearLayout>

解决方案

To make the progress bar show up, you need to turn on ActionBar.DISPLAY_SHOW_CUSTOM in ActionBar.displayOptions.

Catch notes is using a custom animation for their progress bar. I think that the default Holo (normal-sized) one is a reasonable alternative, but to get something like their specific one, you'll want to create an animationDrawable.

Then get the custom view from the ActionBar with getCustomView(), find your ImageView, and start it animating.
