这是我启动活动的代码：

startactivity(new Intent(chck.this,MainActivity.class));

这是我的日志

这是解决方案，希望对您有用。 ***.com/questions/26515058/…

添加一些最简洁的活动代码

【参考方案1】：

在@style/AppTheme.NOactionBar 中添加这两行

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
   </style>

否则删除 android:theme="@style/AppTheme.NoActionBar"

【讨论】：

它仍然无法正常工作。 .当我删除工具栏=（工具栏）findViewById（R.id.toolbar）; setSupportActionBar(工具栏);从 mainactivity 它的作品，但它没有显示我的导航抽屉图标
