要在title栏里设置一个button，新建了title.xml，也在OnCreate方法里调用了requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.activity_main);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
R.layout.title_btn);
但是出错，you cannot combine custom titles with other title features，按照网上的几种方法都试了，结果要不是you cannot combine custom titles with other title features就是03-26 01:54:02.073: E/AndroidRuntime(2790): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.camera/com.example.camera.MainActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
请问前辈这个问题怎么解决啊？
