您实际上可以通过一个非常简单的 hack 更改 AlertDialog 标题的颜色:

You can actually change color of AlertDialog title by a very simple hack:

public static void brandAlertDialog(AlertDialog dialog) {
    try {
        Resources resources = dialog.getContext().getResources();
        int color = resources.getColor(...); // your color here

        int alertTitleId = resources.getIdentifier("alertTitle", "id", "android");
        TextView alertTitle = (TextView) dialog.getWindow().getDecorView().findViewById(alertTitleId);
        alertTitle.setTextColor(color); // change title text color

        int titleDividerId = resources.getIdentifier("titleDivider", "id", "android");
        View titleDivider = dialog.getWindow().getDecorView().findViewById(titleDividerId);
        titleDivider.setBackgroundColor(color); // change divider color
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}
