Android 自定义的checkbox

1 定义显示效果，在res/drawable文件下新建xml文件 如mycheckbox.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_window_focused="false" android:state_enabled="true" android:state_checked="true" android:drawable="@drawable/check1" />
<item android:state_window_focused="false" android:state_enabled="true" android:state_checked="false" android:drawable="@drawable/check2" />
<item android:state_enabled="true" android:state_checked="true" android:state_pressed="true" android:drawable="@drawable/check1" />
<item android:state_enabled="true" android:state_checked="false" android:state_pressed="true" android:drawable="@drawable/check2" />
<item android:state_focused="true" android:state_enabled="true" android:state_checked="true" android:drawable="@drawable/check1" />
<item android:state_focused="true" android:state_enabled="true" android:state_checked="false" android:drawable="@drawable/check2" />
<item android:state_enabled="true" android:state_checked="false" android:drawable="@drawable/check2" />
<item android:state_enabled="true" android:state_checked="true" android:drawable="@drawable/check1" />
</selector>

2 定义checkbox并在其中引用上面定义好的drawable

<CheckBox 
   android:id="@+id/Checked"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:focusable="false"
   android:button="@drawable/mycheckbox"/>
