android开关控件Switch和ToggleButton

序：今天项目中用到了开关按钮控件，查阅了一些资料特地写了这篇博客记录下。

1.Switch

        <Switch
            android:id="@+id/bt"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textOn="开启"
            android:layout_marginLeft="20dp"
            android:textOff="关闭"
            android:showText="true"
            android:thumb="@drawable/shape_thum"
            android:track="@drawable/select_bg_switch"
            />

 

 

 

这里layout_width:这能设置整个布局的宽度，不能设置具体的Switch的大小，需要使用switchMinWidth属性来设置。

    thumb：文字所携带的背景，设置为背景色进行隐藏。不设置会出现一个背景框。

    track：设置开关的背景图片，类似于button的background。

    textoff、texton：设置开关时的文字显示。

 

 

2.ToggleButton

 

<ToggleButton
            android:layout_width="80dp"
            android:layout_height="20dp"
            android:id="@+id/toggle"
            android:layout_centerHorizontal="true"
            android:background="@drawable/shape_track_on"
            android:textOff="off"
            android:textOn="on"
            android:layout_marginLeft="20dp"

            />

 

 

3.效果图

 

 

 1.布局

activity_main.xml
