How to place a screen control in the home screen that will be always visible

I need a screen control (possibly but not mandatory an app widget) that will seat on Android's homescreen and will always be visi开发者_C百科ble to the user - even when he scrolls the homescreen to the next page.

Please help me if any body have done this before.

I think the only way you will be able to do this is if you implement your own Launcher.

The functionality that you're looking for, being able to place a static widget on every screen of the launcher regardless of how many screens they have, isn't currently available in Android, nor any of the launcher apps out there (Go launcher, ADW, Launcher pro etc) nor any of the versions of Android which have been rewritten by the phone manufacturers (HTC's Sense, Samsungs Touch Wiz etc)

It's a big job to write a Launcher yourself, but the stock Android Launcher code is available to play about with from https://android.googlesource.com.
