SwitchView(滑动按钮)

最近写了个滑动按钮，分享给大家，写的不太好，多多包涵。有问题联系我 QQ157688302

最底下提供下载

废话不多说，先上效果图：

先介绍几个特性：

1. 显示的文字可以自己配置

2. 点击控件会自动更改状态（可以通过closeclickevent 函数关闭此功能）。

3. 拖动开关可以更改状态

4. 可通过OnSwitchListener获取事件更改.

5. 拖动开关至边界处,会产生抖动效果.

缺点:

1. 开关的背景图可以自己更换,本人美工不好,图片不是很好看.

2. 代码编写并不是很规范,不好之处还请多多体谅.

3. 没有禁止选择的函数(以后考虑添加)

使用方法:

1. 可以在布局中使用，如果在布局中使用，请务必不要写成wrap_content. 可以自己指定大小或者fill_parent( or match).

xml 实例:

[html] <com.xxx.SwitchView
       android:id="@+id/switch_view"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:layout_alignParentLeft="true"
       android:layout_alignParentBottom="true"
       android:layout_margin="10dp"
       />

<com.xxx.SwitchView
        android:id="@+id/switch_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="10dp"
        />

好了,其他废话不多说,上代码:
