自定义(圆形)切换按钮

Question

我正在尝试在Android中构建自定义切换按钮,我希望它看起来像单选按钮但功能为切换按钮.有人可以帮我弄这个吗？任何线索提示接近答案表示赞赏.

Answer 1

您需要通过一些自定义xml覆盖切换按钮的外观

快速概述:

• 创建具有按钮外观的png文件,如果你喜欢单选按钮,请从...\eclipse_android-sdk-windows\platforms\android-8\data\res\drawable-hdpi抓取它们

• 在你的布局xml android:background ="@ drawable/round_toggle"/>

• 在round_toggle.xml中添加具有多个状态(最多6个默认值)的选择器

  <?xml version="1.0" encoding="UTF-8"?>
  <selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_checked="true" android:state_pressed="true" android:drawable="@drawable/roundtoggle_on_pressed" />
  <item android:state_checked="true" android:state_focused="true" 
       android:drawable="@drawable/roundtoggle_on_focused" />
  <item android:state_checked="true" android:state_focused="false"    
       android:drawable="@drawable/roundtoggle_on_normal" />       
  <item android:state_checked="false" android:state_pressed="true"
       android:drawable="@drawable/roundtoggle_off_pressed" />
  <item android:state_checked="false" android:state_focused="true"
       android:drawable="@drawable/roundtoggle_off_focused" />
  <item android:state_checked="false" android:state_focused="false"
       android:drawable="@drawable/roundtoggle_off_normal" />
  <item android:drawable="@drawable/roundtoggle_off_normal" />
  </selector>
