如何在AlertDialog中更改按钮文本颜色

<style name="CustomAlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:buttonBarButtonStyle">@style/CustomButtonBarButton</item>
</style>

<style name="CustomButtonBarButton" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
    <item name="android:textColor">@color/custom_button_text_color</item>
</style>

<color name="custom_button_text_color">#FF0000</color>

AlertDialog.Builder builder = new AlertDialog.Builder(context, R.style.CustomAlertDialog);
builder.setTitle("Title")
       .setMessage("Message")
       .setPositiveButton("OK", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int which) {
               // 点击确定按钮的逻辑
           }
       })
       .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int which) {
               // 点击取消按钮的逻辑
           }
       })
       .show();
