白色上下文菜单 (copy/paste)

Question

我希望能够从 EditText 框中复制文本。这就是现在的样子，我没有（在顶部栏中）复制突出显示的文本的选项。如何以最简单的方式启用它？

Answer 1

我从主题中更改了图标：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.ituTheme" parent="Theme.AppCompat.Light.NoActionBar">
        ....
       
        <item name="android:actionModeCutDrawable">@drawable/cut</item>
        <item name="actionModeCutDrawable">@drawable/cut</item>
        <item name="android:actionModeCopyDrawable">@drawable/copy</item>
        <item name="actionModeCopyDrawable">@drawable/copy</item>
        <item name="android:actionModePasteDrawable">@drawable/paste</item>
        <item name="actionModePasteDrawable">@drawable/paste</item>
        <item name="android:actionModeSelectAllDrawable">@drawable/select_all</item>
        <item name="actionModeSelectAllDrawable">@drawable/select_all</item>
         ...
    </style>
</resources>

复制、剪切、粘贴，select_all
