Caused by: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
提示这个错误的时候，只需要在配置文件中，找到对应的activity的设置其样式为：
android:theme="@style/AppTheme.NoActionBar">
如果没有成功的话可以在Android的styles.xml中配置如下的命令即可：
<style name="AppTheme.NoActionBar"> <item name="windowActionBar">false</item> <item name="windowNoTitle">true</item> </style>
