推荐答案

您需要引用COMPAT支持库。请看一看到 Android开发者中心。

You need reference a Compat Support Library. Please take a look to Android Developer Center.

如果您使用的是Eclipse：

If you are using Eclipse:

确保您已使用SDK管理器下载Android的支持库。在您的应用程序项目的根目录下创建一个库/目录。的JAR文件从你的Andr​​oid SDK安装目录（例如，/extras/android/support/v4/android-support-v4.jar）到应用程序的项目库/目录拷贝。 右键单击该JAR文件，并选择构建路径>添加到构建路径。

否则，如果您使用Android工作室：

Otherwise if you use Android Studio:

添加相关性：编译com.android.support:appcompat-v7:19.+来的build.gradle在你的模块文件夹文件。确保应用程序兼容性罐子是外部库文件夹。

和您style.xml文件集：机器人：主题=@风格/ Theme.AppCompat

And on your style.xml file set: android:theme="@style/Theme.AppCompat".
