【问题讨论】：
Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
我用那个主题作为基础主题
我是新手 .. 现在卡在这个问题上你能帮帮我吗
整个项目都在这里goo.gl/Ytmpw8
【参考方案1】：
你应该改变java使用的继承
ActionBarActivity
>到
活动
并保持清单中的对话框主题不变。我想你不会有问题的。
【讨论】：
if (toolbar != null) setSupportActionBar(toolbar);最终的 ActionBar actionBar = getSupportActionBar();这些代码无法正常工作以上是关于我的 android studio 项目在棒棒糖上运行良好，但在 kitkat 设备上测试时崩溃的主要内容，如果未能解决你的问题，请参考以下文章
