Android 踩坑記錄

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

Activity繼承了兼容包中的類，查看主題是否來自 Theme.AppCompat

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

若是此處沒有問題或者修改後仍拋出次異常  請檢查引用的插件是否與咱們自定義的主題有衝突 

2、  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 可是主題並未指定正確

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