Activity ActionBar无法显示启动器图标和抽屉布局图标

标签： android android-actionbar android-theme

我想要一个带有操作栏图标，抽屉布局图标和操作栏文本的灯光主题。我在Theme.AppCompat.Light文件中使用了style.xml，如下所示：

<style name="AppTheme" parent="Theme.AppCompat.Light"></style>

它在我的手机上显示了所需的结果，但它只显示了操作栏标题，并且没有显示操作栏图标和抽屉布局图标。

但是当我将主题更改为

时 
<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar"></style>

我收到以下错误。

从所有values文件夹中删除style.xml文件，并将ActionBarActivity重命名为Activity并解决您的错误。

答案 1 :(得分：0)

这是因为新的app-compat with Material。新指南阻止显示图标，您只能通过停用显示标题并使用setCustomView添加带有图标的TextView自定义布局并ActionBar

来将其恢复原状
