<ToggleButton 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/toggle_me"/>

而drawable将是这样的:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true"
        android:drawable="@drawable/toggle_me_on" /> <!-- checked -->
    <item android:drawable="@drawable/toggle_me_off" /> <!-- default/unchecked -->
</selector>

如果你想做形状(不使用图像)试试这个.目前我在自定义复选框中使用它

<com.myapp.views.MyCheckBox xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@android:id/checkbox"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="5dp"
        android:button="@null"
        android:checked="false"
        android:clickable="false"
        android:drawableRight="@drawable/checkbox_selector"
        android:focusable="false"
        android:textColor="@color/orange" />

checkbox_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >

    <item android:state_checked="false"
        android:drawable="@drawable/toggle_button_off" /> <!-- pressed -->
    <item android:state_checked="true"
        android:drawable="@drawable/toggle_button_on" /> <!-- focused -->
    <!-- default -->
    <item
        android:drawable="@drawable/toggle_button_off" />
</selector>

toggle_button_off.xml

    <item


        android:drawable="@drawable/white_toggle_icon"
        android:left="2dp"
        android:right="27.5dp"
        android:bottom="1.5dp"

使用Android-Switch-Demo示例中的以下代码.我可以获得所需的输出.

public MySwitch(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);

    mTextPaint = new TextPaint(Paint.ANTI_ALIAS_FLAG);
    Resources res = getResources();
    mTextPaint.density = res.getDisplayMetrics().density;
    mTextPaint.setShadowLayer(0.5f, 1.0f, 1.0f, Color.BLACK);

    TypedArray a = context.obtainStyledAttributes(attrs,
            R.styleable.MySwitch, defStyle, 0);

    mThumbDrawable = a.getDrawable(R.styleable.MySwitch_thumb);
    mTrackDrawable = a.getDrawable(R.styleable.MySwitch_track);
    mTextOn = a.getText(R.styleable.MySwitch_textOn);
    mTextOff = a.getText(R.styleable.MySwitch_textOff);
    mTextOutsideTrack = a.getBoolean(R.styleable.MySwitch_textOutsideTrack, false);
    mTextOnThumb = a.getBoolean(R.styleable.MySwitch_textOnThumb, false);
    mThumbTextPadding = a.getDimensionPixelSize( R.styleable.MySwitch_thumbTextPadding, 0);
    mTrackTextPadding = a.getDimensionPixelSize( R.styleable.MySwitch_trackTextPadding, 0);
    mSwitchMinWidth = a.getDimensionPixelSize( R.styleable.MySwitch_switchMinWidth, 0);
    mSwitchMinHeight = a.getDimensionPixelSize( R.styleable.MySwitch_switchMinHeight, 0);
    mSwitchPadding =  a.getDimensionPixelSize( R.styleable.MySwitch_switchPadding, 0);

    mTrackDrawable.getPadding(mTrackPaddingRect) ;
    //Log.d(TAG, "mTrackPaddingRect=" + mTrackPaddingRect);
    mThumbDrawable.getPadding(mThumbPaddingRect);
    //Log.d(TAG, "mThumbPaddingRect=" + mTrackPaddingRect);


    int appearance = a.getResourceId(R.styleable.MySwitch_switchTextAppearanceAttrib, 0);
    if (appearance != 0) {
        setSwitchTextAppearance(context, appearance);
    }
    a.recycle();

    ViewConfiguration config = ViewConfiguration.get(context);
    mTouchSlop = config.getScaledTouchSlop();
    mMinFlingVelocity = config.getScaledMinimumFlingVelocity();

    // Refresh display with current params
    refreshDrawableState();
    setChecked(isChecked());
    this.setClickable(true);
    //this.setOnClickListener(clickListener);
}

在此处输入图片说明

我使用SwitchCompat：

<!-- SwitchCompat -->
    <androidx.appcompat.widget.SwitchCompat
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:checked="true"
                android:thumb="@drawable/thumb_selector"
                app:track="@drawable/track_selector"/>


 <!-- thumb_selector.xml -->
      <?xml version="1.0" encoding="utf-8"?>
            <selector xmlns:android="http://schemas.android.com/apk/res/android">
                <item android:state_checked="false">
                    <shape android:shape="oval">
                        <solid android:color="@android:color/white" />
                        <size android:width="20dp" android:height="20dp" />
                        <stroke android:width="2dp" android:color="#0000ffff" />
                    </shape> <!-- shape circle -->
                </item>
            </selector>

 <!-- track_selector.x -->
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_checked="true">
        <shape android:shape="rectangle">

            <solid android:width="1dp" android:color="@android:color/holo_orange_dark"/>
            <corners android:radius="50dp"/>
        </shape>
    </item>

    <item android:state_checked="false">
        <shape android:shape="rectangle">
            <size android:width="36dp" android:height="20dp"/>
            <solid android:width="1dp" android:color="@android:color/darker_gray"/>
