Apps To apply translucent themes in android activites

[kiiirtiii]

Hi,

I am really new to android and this forum. So I'm not sure how to phrase things here. Anyways, here goes.

I want all my activities to have a certain background image. But i also wish to make my window translucent. So:
1) a specific background image for my window.
2) the window must be translucent.
3) the widgets(again with a background) on my activity must also be translucent.

What do I do?

I tried to use the Theme.Translucent and making windowIsTranslucent attribute true. But it still doesn't work. I specify my background in LinearLayout definition and it appears as an opaque background. Also, my buttons also remain opaque!

Regards,
Kiii
