本文介绍了如何在代码中进行Android SDK版本的判断，并详细列出了不同版本号的定义，帮助开发者理解并正确处理不同Android版本之间的差异。

<span style="background-color: rgb(255, 255, 255);">f</span>

这是sdk版本判断的代码:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">) </span>

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">{</span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"> </span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">ActionBar ab = getActivity().getActionBar();</span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"></span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">ab.setTitle("请选择");</span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"> </span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">} else {</span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"> </span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">getActivity().setTitle("请选择");</span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"></span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">}</span>

下面是各版本号的定义:
