一、java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

Activity继承了兼容包中的类，查看主题是否来自 Theme.AppCompat

<style name="BaseTheme.Light" parent="Theme.AppCompat"

二、  Caused by: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
  

使用Toolbar 但是主题并未指定正确

<style name="BaseTheme.Light" parent="Theme.AppCompat.Light.NoActionBar">
