在我的onCreate（）我设置一个进度条如下：

In my onCreate() I set a progress bar as follows:

getWindow().requestFeature(Window.FEATURE_PROGRESS);
getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);

现在，希望加强这种标题栏一点点，我想改变它的背景的颜色。第一步是检查 FEATURE_CUSTOM_TITLE 支持：

Now, wishing to enhance that title bar a little bit, I want to change its background color. First step is to check if FEATURE_CUSTOM_TITLE is supported:

final boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
if ( customTitleSupported ) {
    Log.i(TAG, "CUSTOM TITLE SUPPORTED!")
}

但只要我称之为 requestWindowFeature（Window.FEATURE_CUSTOM_TITLE）我得到一个：

AndroidRuntimeException: You cannot combine custom titles with other title features

（这并不重要，如果我设置之前调用此函数 FEATURE_PROGRESS 或之后）的

(It doesn't matter if I call this function before setting FEATURE_PROGRESS or after)

不知道如何解决呢？

或者，我会避免定制的标题栏，如果我能找到的非定制标题栏的资源 ID 。东西是不是危险的getParent（）更好。

Alternatively, I would avoid a custom title bar, if I could find the non-custom title bar's resource ID. Something that's better than the dangerous getParent().

这可能吗？

推荐答案

作为的文件说：

FEATURE_CUSTOM_TITLE

FEATURE_CUSTOM_TITLE

标记的自定义标题。不能将这个   功能与其他标题的功能。

Flag for custom title. You cannot combine this feature with other title features.

什么，你提到你可以做的是使用一个进度条的自定义标题栏，的下面是一个例子如何实现这一目标。

What you can do as you mentioned is to use a custom title bar with a ProgressBar, here is an example how to accomplish that.

在另一方面，你为什么不使用操作栏？

In the other hand, why aren't you using Action Bar?.
