什么是TitleBar的默认高度和Android中Titlebar中的默认TextSize？

您可以在此处找到默认高度

http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.3_r1/frameworks/base/core/res/res/values/dimens.xml

以下是4.0.3

<dimen name="action_bar_default_height">48dip</dimen>
<dimen name="action_bar_title_text_size">18dp</dimen>

检查各个res / values文件夹下的dimens.xml
