如何在警报对话框中更改按钮的颜色 [英] How to change color of Button in Alert Dialog

问题描述

这是我用于创建对话框的代码，

Here my code for create Dialog,

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

是否可以用蓝色而不是红色显示关闭?

Is it possible to display dismiss in blue color rather than red?

推荐答案

首先，从构建器创建AlertDialog:

First, create AlertDialog from builder:

AlertDialog dialog = builder.create();

然后您可以找到按钮并更改颜色:

Then you can find your button and change color:

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);

在此使用下一个方法:

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.
