Please help me how can i do this. Thanks for ur valuable time .

Answer 1

I would give a try to a ViewFlipper activity, with two screens. This, of course, if you can encapsulate your actions into one activity (which i'm sure is manageable with AsyncTasks / Threads , Services and Handlers ).

This way you can use gestures, (soft/hard)buttons, dropdowns, -whatever-, to navigate between your screens.

Answer 2

You can automatically go back to a previous activity on the Activity stack by calling the finish() method.

If you want to do this without any user interaction, use a Handler that automatically calls finish() on your activity after a predefined timeout (see this article for more information on Handlers).

Answer 3

尝试使用Thread.sleep（[ms]）然后调用完成或调用intent到第一个

Answer 4

The one solution is, when you press BACK button from second screen instead of call finish(); you should start first activity again, so the activity stack will be

FIRST
SECOND
FIRST

so after the delay of two second your activity will finish and eventually will come back to second screen, and state will be maintained also.
