這裏我爲創建對話框代碼,如何更改按鈕的顏色在警報對話框

   builder.setMessage(msg).setNeutralButton("Dismiss",dialogClickListener).setPositiveButton("Edit", dialogClickListener) 
        .setNegativeButton("Delete", dialogClickListener).show(); 

是否有可能顯示駁回藍色,而不是紅色的?

Sheikh給出的答案告訴我AlertDialog dialog = builder.create(); Brahmy adigopula在原始問題中的回答僅僅是指AlertDialog.show出於藍色 – alberto

首先,從生成器來創建AlertDialog:

AlertDialog dialog = builder.create(); 

然後你就可以找到您的按鈕和更改顏色:

dialog.show(); //Only after .show() was called 
dialog.getButton(dialog.BUTTON_NEGATIVE).setTextColor(your_color); 
dialog.getButton(dialog.BUTTON_POSITIVE).setTextColor(your_color); 
dialog.getButton(dialog.BUTTON_NEUTRAL).setTextColor(your_color); 

這裏您使用下一個method

void setTextColor (int color) 
    Sets the text color for all the states (normal, selected, focused) to be this color. 
Parameters 
    color int: A color value in the form 0xAARRGGBB. Do not pass a resource ID. To get a color value from a resource ID, call getColor.

謝謝你,一個有點神祕的答案,但它指出我正確的方向,現在它的作品。 – alberto

啊這是可能的,顏色從風格改變,你可以自定義樣式您的對話框如下圖所示:

<style name="AlertDialogCustom" parent="android:Theme.Material.Light.Dialog.Alert"> 
    <item name="android:colorPrimary">yourColorCode</item> 
    <item name="android:colorAccent">yourColorCode</item> 
</style>
