如何更改警报对话框中按钮的颜色

Question

这是我创建对话框的代码，

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解雇？

Answer 1

首先，从构建器创建 AlertDialog：

AlertDialog dialog = builder.create();

然后你可以找到你的按钮并改变颜色：

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);

这里你使用下一个方法：

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.
