Question

I currently have a TabActivity which has 4 tabs, within one of the tab’s I want to be able to move forward and back between 4 different Activities.

However if I try to start a new Activity now it removes the TabActivty and starts a whole new Activity with no tab bars.

I have read about using view groups but that this is not best practice and also about using a view flipper but this doesn’t seem to let me switch between different Activities only change the views within the Activity. I can’t implement back functionality for exa,ple.

Can anyone point me in the right direction as to what I should be looking for as a solution to this?

EDIT:

Some more information:

Within the TabActivity my first screen will be a ListView that contains 4 rows, then selecting one of these will in turn load another ListView with 2 rows again within the TabActivity and then the 3rd screen will just contain some text depending on which option the user chose again within the Tab Activity.

Is a ViewFlipper the best solution here? It seems to me that it will require a lot of coding within one Activity if I use the ViewFlipper?

Answer 1

I have done something similar. I used the ViewFlipper to achieve this. You can override onBackPressed in your Activity so you can deal with moving back through your views.

There’s a couple of ways of doing this but a simple way would be to just increment a counter in your Activity as you move to the next views, then in your onBackPressed method if counter != 0 just show the previous view, if counter == 0 call super.onBackPressed.

You can see in my video showing what the result could look like (ignore the bug being shown in the video).
