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"

            />

1.布局

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:orientation="horizontal"
        android:layout_marginTop="30dp"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="开关"
            />
        <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"

        //状态改变监听
        aSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
