如何在选择器中设置按钮的文本样式? [英] How to set the text style of a button in selectors?

问题描述

按钮选择器允许为按钮的每个状态定义背景，但是如何为每个状态定义按钮的文本样式?我的目标是在禁用时使按钮变灰.因此，我将灰色背景设置为按钮的禁用状态，但我发现使文本变灰的唯一方法是在禁用按钮时动态更改其颜色...

Button selectors allows to define a background for each state of the button, but how can the button's text style be defined for each state? My objective is to grey out a button when disabled. So I set a greyed out background to the disable state of the button, but the only way I found to also grey out the text is to change it's color dynamically when I disable the button...

有人可以帮忙吗?

谢谢

<style name="srp_button" parent="@android:style/Widget.Button">
    <item name="android:background">@drawable/btn_default</item>
    <item name="android:textColor">#ffffff</item> <!-- How to specify different color for different state? -->
    <!-- more stuff -->
</style>

drawable/btn_default.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_enabled="true"><shape>
            <solid android:color="@color/pink" />
            <corners android:radius="6dp" />
        </shape></item>
    <item><shape>
            <solid android:color="#000000" />
            <corners android:radius="6dp" />
        </shape></item>

</selector>

推荐答案

好吧！

您可以为所有 4 个状态定义文本颜色，类似于为 Button 定义背景.例如:

You can define the Text color for all 4 state, similarly as you defined background for the Button. For example:

文件名:/res/color/text_color.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="false" android:color="#440000"/>
    <item android:state_focused="true" android:color="#004400"/>
    <item android:state_pressed="true" android:color="#000044"/>
    <item android:color="#444"/> 
</selector>

将此文件放入您的 Button 样式中，如下所示:

Take this file into your Button Style like this:

<style name="srp_button" parent="@android:style/Widget.Button">
    <item name="android:background">@drawable/btn_default</item>
    <item name="android:textColor">@color/text_color</item> <!-- Here is specified text color -->
</style>
