1.先在xml文件添加一个控件ToggleButton并设置相关属性：
android:textOn="开时显示的文字"
android:textOff="关时显示的文字"
android:checked="默认状态是开是关"
2.在MainActivity文件里定义一个ToggleButton控件并实例化，实现ToggleButton控件的监
if(arg1)
{
开时要实现的操作
}
else
{
关时要实现的操作
}
3.详见源代码

<ToggleButton
android:id="@+id/mytb"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textOn="开"
android:textOff="关"
android:checked="false"/>
<TextView
android:id="@+id/mytv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="开关关闭了"
/>
</LinearLayout>
