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