我已经尝试了所有可能的解决办法。仍无法运行应用程序。请帮助。尝试删除true
中的android前缀，即将其替换为true
另外，将
替换为
，不需要Light.darkaActionBar部分，因为您将windowActionbar
指定为false，将windowNoTitle
指定为true，并在活动中设置操作栏
还有一件事，ActionBarActivity在支持库的修订版22.1.0中被弃用，因此应使用AppCompatActivity代替ActionBarActivity。这和问题无关，只是一个建议
希望这将帮助您解决问题，因为代码的所有其他部分看起来都正常。
尝试从以下位置更改app/src/main/res/values/style.xml：
致：
我已尝试根据现有答案在styles.xml中进行更改，但到目前为止运气不佳。@RishikaKapur尝试实施我在下面建议的更改。非常感谢@AlokNair。应用程序现在运行良好。但是有一个小问题，activity_main.xml
-呈现问题java.lang.NullPointerException位于com.android.layoutlib.bridge.impl.RenderSessionImpl.isThemeAppCompat（RenderSessionImpl.java:1203）位于com.android.layoutlib.bridge.impl.RenderSessionImpl.findStatusBar（RenderSessionImpl.java:1066）
