Android：点击更改字体颜色 [英] Android: change font color on click

问题描述

我想改变按钮内的文字颜色。

例如，我有一个按钮，用白色填充，文本是蓝色。当我点击按钮我想要这两种颜色交换（按钮内的文字变成白色和按钮蓝色）。

我试过这样： p>

 < item style =@ style / ButtonText_Menue_Clickedandroid：drawable =@ drawable / button_menue_defaultandroid：state_focused =true >< / item> 
< item style =@ style / ButtonText_Menueandroid：drawable =@ drawable / button_menue_default>< / item> 
  

但实际上什么都不做。
有任何方法来做我想要的，或者我必须做一些东西在onclik事件（但是有问题如何设置颜色回来，当点击消失）

解决方案

在 res / color中创建选择器 / code>为 res / drawable 的文本颜色和按钮 selector / p>



text_color.xml

 < selector 
 xmlns： android =http://schemas.android.com/apk/res/android> 
< item 
 android：state_pressed =true
 android：color =＃800000/> 
< item 
 android：state_pressed =false
 android：color =＃4C5/> 
< / selector> 
  

button_color.xml

 <？xml version =1.0encoding =utf-8？> 
< selector 
 xmlns：android =http://schemas.android.com/apk/res/android> 
< item 
 android：state_pressed =true> 
< shape android：shape =rectangle> 
< solid android：color =＃4C5/> 
< / shape> 
< / item> 
< item 
 android：state_pressed =false> 
< shape android：shape =rectangle> 
< solid android：color =＃800000/> 
< / shape> 
< / item> 
< / selector> 
  

将按钮添加到布局

 < Button 
 android：id =@ + id / button1
 android：layout_width =wrap_content
 android：layout_height =wrap_content
 android：text =Button
 android：textColor =@ color / text_color
 android：background =@ drawable / button_color/> 
  




i am trying to change the color of text inside a button.

So for example i have a button which is filled with white and the text is blue. When i click on the button i want these two colors to swap (text inside the button becomes white and the button blue).

I have tried something like this:

 <item style="@style/ButtonText_Menue_Clicked" android:drawable="@drawable/button_menue_default" android:state_focused="true"></item>
 <item style="@style/ButtonText_Menue" android:drawable="@drawable/button_menue_default" ></item>

but it actually does nothing. Is there any way to do what i want, or do i have to do some stuff in the onclik event (but then there is the problem how to set the colors back when the "click is gone" )

解决方案

Create a selector resource in res/color for the text color and a button selector in res/drawable as below...

text_color.xml

<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_pressed="true"
        android:color="#800000" />
    <item
        android:state_pressed="false"
        android:color="#4C5" />
</selector>

button_color.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_pressed="true">
        <shape android:shape="rectangle">
            <solid android:color="#4C5"/>
        </shape>
    </item>
    <item
        android:state_pressed="false">
        <shape android:shape="rectangle"  >
            <solid android:color="#800000"/>
        </shape>
    </item>
</selector>

Add the button to the layout

 <Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button"
    android:textColor="@color/text_color"
    android:background="@drawable/button_color"/>
