android:theme="@android:style/Theme.Black.NoTitleBar"使用出错

Question

为什么我写上android:theme="@android:style/Theme.Black.NoTitleBar"后就无法运行模拟器了报出java.lang.RuntimeException: Unable to start activity ComponentInfo{com.imooc.jisuanqi/com.imooc.jisuanqi.MainActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2148)等问题
