导航抽屉中缺少操作栏
[英]Action Bar missing in Navigation Drawer
问题描述
I have been working on Navigation Drawer. 
我一直在研究导航抽屉。 But my getActionBar() is getting caught in NullPointerException. 但是我的getActionBar（）陷入了NullPointerException。 On surrounding it with try and catch, the ActionBar becomes invisible. 通过尝试和捕获将其包围时，ActionBar变为不可见。 Any suggestion how to fix it? 有什么建议如何解决吗？

Put getWindow().requestFeature(Window.FEATURE_ACTION_BAR); 放入getWindow().requestFeature(Window.FEATURE_ACTION_BAR); above your R.layout line. 在您的R.layout线上方。 Hope this helps. 希望这可以帮助。
