猿问

加了这句@android:style/Theme.Black.NoTitleBar程序不能运行

E/AndroidRuntime: FATAL EXCEPTION: main
                  Process: com.example.girdview, PID: 3368
                  java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.girdview/com.example.girdview.MainActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

版本不兼容这个吗,只能使用自定义样式,系统样式不行,怎么解决?
