更改AlertDialog的样式 [英] Change the style of AlertDialog

问题描述

当我运行此代码时，将显示警告对话框，但对话框周围有一个白色边框，边框也很圆。我不想要这个白色边框，我想要有角度为90°的真正的角落。我希望你明白我想做什么。

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();

是否有任何方式来设置警报对话框，而不是文本颜色或文字大小或类似的东西...我想风格的警报对话框的边框，所以设置只是一个主题也许是解决这个问题。但我不知道要覆盖的属性。

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.

感谢，

编辑：
例如这种风格覆盖textColor为00FF00，这是很酷，但哪个属性应该覆盖，使角不圆，并删除白色的钻石

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

我找到了包装器的解决方案，一个主题（风格）到当前上下文中的任何东西。我将R.style.MyTheme设置为我的警报对话框的样式，并根据自己的口味定制了该视图。

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 );
