Android Showing two activity same time

I have an app which shows two activities at the same time;

Because my application using surfaceview but surfaceview never accept behind view.

• FrameLayout
  • ImageView
  • SufaceView at that time i never seen ImageView by every way.

But I solve that problem by Using Two Activities.

1. Execute Activity A (Activity A (Game Background and Character))
2. Activity A intent B (Activity B (Game UI & Game Enemy))

finally I can see that I want.

My Question:

Usual Activity B is faster than Activity A because A is not focused, just showing

1. Some devices 开发者_运维技巧(Galaxy S2 that I know) Activity B is slower than Activity A

Plz Give me a favor I'm falling in this problem for 1 month....... T.T

I'm not sure what you mean by this because Android only allows 1 activity to run a time. When you start Activity B from Activity A, A gets paused.

Again I'm not sure what this means, but as it looks like you're making a game I'd suggest you read this blogpost: http://www.rbgrn.net/content/54-getting-started-android-game-development

Maybe buy this book: http://www.amazon.com/Beginning-Android-Games-Mario-Zechner/dp/1430230428/ref=sr_1_1?ie=UTF8&qid=1304580271&sr=8-1
