问题描述

当我运行此代码时，会显示警报对话框，但对话框周围有一个白色边框，而且边框有点圆.我不想要这个白色边框，我想要真正的角为 90 度.我希望你明白我在做什么.

When I run this code the alert dialog is shown but there is one white border around the dialog and also the borders are little round. I do not want this white border and I want to have real corners with angle of 90. I hope you understand what I am trying to do.

        AlertDialog.Builder ad = new AlertDialog.Builder(this);
        Button bbb=new Button(MvcnContactList.this);
        ad.setView(bbb);
        alertDialog = ad.create();
        alertDialog.show();

有什么方法可以设置警报对话框的样式，但不能设置文本颜色或文本大小或类似的样式...我想设置警报对话框的边框样式，因此仅设置一个主题也许可以解决此问题.但我不知道要覆盖哪些属性.

Is there any way to style the alert dialog but not the text color or text size or something similar... I want to style the borders of the alert dialog, so setting just a theme maybe it is solution to this problem. But I do not know what properties to override.

谢谢，

例如，这种样式将 textColor 覆盖为 00FF00 ，这很酷，但是我应该覆盖哪个属性以使角不圆并移除那个白色的钻孔

For example this style override the textColor to 00FF00 , and that is cool, but which property should I override to make the corners not round and tho remove that white boreder

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AlertDialogCustom" parent="@android:style/AlertDialog">
        <item name="android:textColor">#00FF00</item>
        <item name="android:typeface">monospace</item>
        <item name="android:textSize">10sp</item>
    </style>
</resources>

推荐答案

我找到了使用包装器的解决方案，您可以在其中为当前上下文中的任何内容设置主题(样式).我将 R.style.MyTheme 设置为警报对话框的样式，并根据自己的喜好定制了该视图.

I found solution with the wrapper, where you can set a theme (style) to anything in the current context. I set R.style.MyTheme as style to my alert dialog and I customized that view to my own taste.

ContextThemeWrapper ctw = new ContextThemeWrapper( this, R.style.MyTheme );
        AlertDialog.Builder builder= new AlertDialog.Builder( ctw );
