我有一个简单的警报对话框与单一的选择项目

val alertDialog = AlertDialog.Builder(this)
alertDialog.setTitle("My Title")
val array = arrayOf("aa", "bb", "cc")
alertDialog.setSingleChoiceItems(array, 0) { _, selectedItem ->
}
alertDialog.setNegativeButton("Cancel") { _, _ ->
}
alertDialog.create()
alertDialog.show()

我已经添加到我的主题自定义样式的警报对话框

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

     .........
     <item name="android:timePickerDialogTheme">@style/DefaultAlertDialogTheme</item>
     <item name="android:datePickerDialogTheme">@style/DefaultAlertDialogTheme</item>
     <item name="android:alertDialogTheme">@style/DefaultAlertDialogTheme</item>
</style>

这是我的风格

<style name="DefaultAlertDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:colorAccent">@color/greenButtonBackgroundColor</item>
    <item name="android:textColorSecondary">@color/greenButtonBackgroundColor</item>
    <!--title-->
    <item name="android:textColor">@color/toolbarTitleTextColor</item>
</style>

当我运行应用程序时，我看到此警报

有没有办法在不创建自定义布局的情况下更改单选按钮附近文本的颜色？

为单选按钮项着色的样式

<style name="DefaultAlertDialogTheme" parent="Theme.MaterialComponents.Light.Dialog.Alert">
    <!--        Title Color-->
    <item name="android:textColorPrimary">@color/black</item>
    <!--        Radio button unchecked-->
    <item name="android:colorControlNormal">@color/medium_gray</item>
    <!--        Radio button checked-->
    <item name="android:colorControlActivated">@color/warmPink</item>
    <!--        List item on click highlight color-->
    <item name="android:colorControlHighlight">@color/transparent</item>
</style>

你可以做得很有格调

<style name="MyDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">                      
    <item name="android:textColor">@color/your_text_color_here</item>       
</style>

然后在代码中这样做

val alertDialog = AlertDialog.Builder(this, R.style.MyDialogTheme)

试试这个

val array = arrayOf(Html.fromHtml("<font color='#00FF00'>aa</font>"),
                Html.fromHtml("<font color='#00FF00'>bb</font>"),
                Html.fromHtml("<font color='#00FF00'>cc</font>"))

Add into Style to change the color of radio button items

<style name="DefaultAlertDialogTheme" parent="Theme.MaterialComponents.Light.Dialog.Alert">
    <item name="android:textColorPrimary">@color/white</item>
    <item name="android:colorControlNormal">@color/gray</item
    <item name="android:colorControlActivated">@color/blue</item>
    <item name="android:colorControlHighlight">@color/light_gray</item>
</style>

If you need to change radiobutton text color add this in your styles" 

    <item name="textColorAlertDialogListItem">@color/color_white</item>"
