安卓:显示在TabHost活动不确定的进度栏 [英] Android: Showing indeterminate progress bar in TabHost activity
问题描述
我知道下面的code应该显示和隐藏在Android的下code一个很小的圆形进度条:
I know that the following code should show and hide a tiny circular progress bar with the following code in Android:
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setProgressBarIndeterminateVisibility(true);
setProgressBarIndeterminateVisibility(false);
问题是,我使用的是TabHost和我需要能够从儿童的活动之一做到这一点。有没有什么方法可以让我去这样做?
The problem is that I am using a TabHost and I need to be able to do this from one of the "child" activities. Is there any way I can go about doing this?
我发现这个问题在intarwebs但正如你所看到的,它无人接听。
I found this question on the intarwebs but as you can see, it went unanswered.
推荐答案
和我找到了答案。在你父母的活动,你做的什么之前,你需要做的requestWindowFeature通话,然后在你的孩子的活动,你叫的getParent()setProgressBarIndeterminateVisibility(真/假)。
And I found the answer. In your parent activity, before you do anything, you need to do the requestWindowFeature call, and then in your child activity you call getParent().setProgressBarIndeterminateVisibility(true/false);
