Logo SwitchButton

SwitchButton是用在Android上的开关按钮，最低兼容Android2.2

sample

##Features

  • 支持滑动切换
  • 支持标题
  • 支持Left、Top、Right、Bottom Drawable
  • 支持使用遮罩实现圆角按钮

##Usage ####1.图片准备

switch_frame.png switch_frame.png

switch_state_normal.png switch_state_normal.png

switch_state_disable.png switch_state_disable.png

switch_state_mask.png switch_state_mask.png

switch_slider_normal.png switch_slider_normal.png

switch_slider_disable.png switch_slider_disable.png

selector_switch_state.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_enabled="false" android:drawable="@drawable/switch_state_disable"/>
    <item android:drawable="@drawable/switch_state_normal"/>
</selector>

selector_switch_slider.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_enabled="false" android:drawable="@drawable/switch_slider_disable"/>
    <item android:drawable="@drawable/switch_slider_normal"/>
</selector>

####2.下载属性文件**attrs.xml**并放到values目录下。源码如下，也可复制粘贴到项目中

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="SwitchButton">
        <attr name="frameDrawable" format="reference|color"/>
        <attr name="stateDrawable" format="reference|color"/>
        <attr name="stateMaskDrawable" format="reference|color"/>
        <attr name="sliderDrawable" format="reference|color"/>
	    <attr name="withTextInterval" format="dimension"/>
    </declare-styleable>
</resources>

####3.下载**SwitchButton.java**并放到任意源码目录下，注意放到你项目中要修改R文件的引用才能编译通过

####4.在布局中添加自定义属性并引用SwitchButton

<?xml version="1.0" encoding="utf-8"?>
<me.xiaopan.android.switchbutton.SwitchButton
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res/me.xiaopan.android.switchbutton"
    android:id="@+id/switch"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="50dp"
    android:paddingLeft="30dp"
    android:paddingRight="30dp"
    android:text="接受推送"
    app:withTextInterval="16dp"
    app:frameDrawable="@drawable/switch_frame"
    app:stateDrawable="@drawable/selector_switch_state"
    app:stateMaskDrawable="@drawable/switch_state_mask"
    app:sliderDrawable="@drawable/selector_switch_slider"/>

####5.属性解释

  • withTextInterval：标题文字和按钮之间的距离
  • frameDrawable：框架图片，定义按钮的大小以及显示区域
  • stateDrawable：状态图片，显示开启或关闭
  • stateMaskDrawable：状态图片遮罩层
  • sliderDrawable：滑块图片

####6.其它方法：

  • setDrawables(Drawable frameBitmap, Drawable stateDrawable, Drawable stateMaskDrawable, Drawable sliderDrawable)：设置图片
  • setDrawableResIds(int frameDrawableResId, int stateDrawableResId, int stateMaskDrawableResId, int sliderDrawableResId)：设置图片ID
  • setWithTextInterval(int withTextInterval)：设置标题和按钮的间距，默认为16
  • setDuration(int duration)：设置动画持续时间，单位毫秒，默认为200
  • setMinChangeDistanceScale(float minChangeDistanceScale)：设置滑动有效距离比例，默认为0.2。例如按钮宽度为100，比例为0.2，那么只有当滑动距离大于等于(100*0.2)才会切换状态，否则就回滚
