Slide Toggle for Android

you can use the sliding drawer widget in android to have a sliding toggle switch. you just have to "slice" the ios toggle images into3 parts, one for the handle, one for the sliding drawer background and one for the content part. then put an image on top of it like a frame to give you the "round edges"

here's what i've come up with: XML Layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    <FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="100dp" >
        <SlidingDrawer
            android:id="@+id/slidingDrawer1"
            android:layout_width="154dp"
            android:layout_height="54dp"
            android:background="@drawable/ios_retina_toggle_on_full"
            android:content="@+id/content"
            android:handle="@+id/handle"
            android:orientation="horizontal" >
            <ImageButton
                android:id="@+id/handle"
                android:layout_width="54dp"
                android:layout_height="54dp"
                android:background="#00000000"
                android:src="@drawable/ios_retina_toggle_button" />
            <ImageView
                android:id="@+id/content"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/ios_retina_toggle_off" />
        </SlidingDrawer>
        <ImageView
            android:id="@+id/imageView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ios_retina_toggle_frame" />
    </FrameLayout>
</LinearLayout>

ios_retina_toggle_on_full

ios_retina_toggle_button

ios_retina_toggle_off

ios_retina_toggle_frame

and finally a screenshot of how it looked on the emulator on a 3.7 WVGA screen running gingerbread:

iOS does not seem to have a "slide toggle", at least under that name, based on a Google search. And, you did not provide an image (or a link to an image) of what you want.

Android 4.0 added a Switch that you might be able to backport to earlier versions. You will see samples of it in the API Demos app on your emulator:
