我用

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setSupportProgressBarIndeterminateVisibility(true);
setSupportProgressBarIndeterminateVisibility(false);

启用/禁用不确定的进度条。随着ActionBarSherlock，它的所有设备的工作，但与ActionBarCompat使用时，它仅适用于Android的版本2.3以上。

to enable/disable indeterminate progress bar. With ActionBarSherlock, it worked with all devices but when using it with ActionBarCompat, it works only for Android versions above 2.3.

我想过使用，而不是窗口WindowCompat但WindowCompat没有FEATURE_INDETERMINATE_PROGRESS标志。

I thought about using WindowCompat instead of Window but WindowCompat doesn't have FEATURE_INDETERMINATE_PROGRESS flag.

推荐答案

ActionBarActivity 现在有 supportRequestWindowFeature ，你可能需要用它来获得完整的功能。

ActionBarActivity now has supportRequestWindowFeature, you probably need to use that to get the full functionality.
