我在我的应用程序中使用android动作栏我已经成功实现了动作栏，但它仅适用于3.0或更高版本
文档说动作栏是在android蜂窝中引入的，它有api版本11，我的代码工作时我有android：minSdkVersion 11，我想让它在Android 2.2或更高版本上工作 即android：minSdkVersion =＆＃34; 8＆＃34;
我已经包含了 import android.support.v7.app.ActionBar ;然而，即使这样它也无法正常工作
我不想使用actionbarsherlock
我想使用getActionBar（）。setDisplayHomeAsUpEnabled（true），
我甚至尝试过使用getSupportActionBar（）。setDisplayHomeAsUpEnabled（true）;它也不起作用这是我的代码给我错误消息方法getSupportActionBar（）未定义类型活动
