例如,这是我的一个应用程序中使用的类,它模仿了 ActionBar.Tabs 。

您可以使用真实 ActionBar.Tabs 的默认绘图和属性来给您充气。 您可以从 SDK 或网络上某个地方抓取它们。 要使用它, 请在 标上附加一个 ViewPager , 并在 StabView 中添加每个 fractionments , 在 FraggmentPagerAdapter 中键入样式。 < a href=" https://i. statistic. net/7GCFz.png" rel=" no folpol " 这就是它们看起来的样子, 如果您在添加默认绘图和属性 之后对样式表示好奇的话, 。
