问题描述
如何在按下按钮时使用 xml 更改文本和背景颜色?
How can I change both text and background colors when my button is pressed, with xml ?
要更改文本颜色,我可以这样做:
To change text color I can do :
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="mycolor"/>
<item android:color="mycolor2"/>
</selector>
要更改我可以做的背景(在具有可绘制参考的选择器/项目中使用它):
To change the background I can do (using it in a selector/item with drawable reference) :
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FF0079FF" />
</shape>
但是我怎样才能做到这两点呢?假设我想要:
But how can I do both ? Let's say I want to have :
- 默认:黑色文本/白色背景
- 按下:白色文字/蓝色背景
我完全忘记了背景和文本颜色是分开管理的,所以我是这样做的:
I totaly forgot that the background and text color are managed separately, so this is how I did it :
<Button
android:textColor="@color/filtersbuttoncolors"
android:background="@drawable/mybackgroundcolors" />
在 mybackgroundcolors.xml 中我管理背景,在 filtersbuttoncolors.xml 中我管理文本颜色.在这两个 xml 文件中,我管理状态(按下、选择、默认)
In mybackgroundcolors.xml I manage the background and in filtersbuttoncolors.xml I manage the text color. In both xml files I manage the status (pressed, selected, default)
推荐答案
这是一个默认情况下为白色的 drawable 示例,按下时为黑色:
Here is an example of a drawable that will be white by default, black when pressed:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape>
<solid
android:color="#1E669B"/>
<stroke
android:width="2dp"
android:color="#1B5E91"/>
<corners
android:radius="6dp"/>
<padding
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp"/>
</shape>
</item>
<item>
<shape>
<gradient
android:angle="270"
android:endColor="#1E669B"
android:startColor="#1E669B"/>
<stroke
android:width="4dp"
android:color="#1B5E91"/>
<corners
android:radius="7dp"/>
<padding
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp"/>
</shape>
</item>
</selector>
