More info on this link: http://www.mokasocial.com/2011/07/sexily-styled-toggle-buttons-for-android/

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

and the drawable will be something like:

<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>

If you want to do with shapes (without using images) try this. Currently im using it in a custom checkbox

<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

    <item android:state_checked="true"
        android:drawable="@drawable/toggle_button_on" /> <!-- focused -->

Use of below code from Android-Switch-Demo example. I can get desired output.

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);
}

take all the images of off and on button and make a layout in relative layout like this

            <RelativeLayout
                android:id="@+id/setting1"
                android:layout_width="90dp"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:layout_alignParentTop="true"
                android:background="@drawable/switchon"
                android:clickable="true"
                android:onClick="setting1Click" >

                <ImageView
                    android:id="@+id/settingicon"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_alignParentRight="true"
                    android:src="@drawable/switchball" />

                <TextView
                    android:id="@+id/calsettingtxt"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerVertical="true"
                    android:layout_marginRight="10dp"
                    android:layout_toLeftOf="@+id/settingicon"
                    android:text="@string/settingon"
                    android:textColor="@color/black"
                    android:textSize="18sp"
                    android:textStyle="bold" />
            </RelativeLayout>

then in code when on is pressed make the background resource as off
