My TabActivity contains two tabs which calls two two different activities . I want to setResult() for the TabActivity when either one of the child finishes.
Is there any method to find out when my activity inside tab finishes?

I have an Tab Activity with 4 tabs. Each of tab is showing me the list view. Suppose i m on 4th tab and dragged the list view to the last position and after that i click on 3rd tab and again when i go to 4th tab it is not refreshing and showing me the last visible screen. Actually i want to show the list view again from 1st element. is tabs refresh automatically or we need to do it programmatic?

I am trying to figure out the best practice of communication between a TabActivity and the child activity embedded in this TabActivity.
In my TabActivity, there is a button. When the button is clicked, I want the child activity embedded in this TabActivity to be updated. I wrote the code like below, and just wonder whether it is a good practice.

I have a TabActivity. Each tab points to a sub activity. Works great.
Is there any clever way to refresh one of the activity tabs? I just want to 'restart' the activity in tab #3 for example. Not sure of a good way to do this other than building in refresh support to the activity itself, or clearing ALL the tabs and recreating all of them.
I want to add tabs to the layout of my activity, but I don't want the activity to extend TabActivity. The example in http://developer.android.com/resources/tutorials/views/hello-tabwidget.html only gave example of subclass of TabActivity.
Is there any way I can make it without extending TabActivity?

I did try this:((TeamHuddleScreenMsgsView)getTabHost().getCurrentTabView().getContext()).refreshModel(); but I'm encountering a ClassCastException. It seems that the getContext() still gives the TabActivity. Any help on how to get the child Activity?
I have attached a menu to my TabActivity, and when a menu item is selected, I would like to do something different based on which view is being currently displayed in the TabHost.
int getCurrentTab() returns me the id of the current tab... but from that int how can I get the instance of the activity running?
I also tried getCurrentView(), getCurrentTabView(), but these return things I can't seem to cast to the class of the current activity.

The Android Developers Hello Views Tab Layout example only details how to use separate Activities for each Tab.
I would like to use tabs to extend a screen of settings without scrolling, i.e. there are too many options for a single screen, so I'd like to split them over two tabs, but still handle them in the same Activity.
Each tab can refer to a separate layout file if that is how it needs to be done.
My first page contains 3 tabs. I want to retain all these 3 tabs through out my entire application. That means I want to see these 3 tabs in every view. For example : I have 3 views. First view is Main.class. It contains 3 tabs (Home tab, Favourite tab, settings tab). When I am clicking any one tab (Ex: Home Tab), it shows the contents of Home.class (a ListView) below these tabs. But when I am clicking the ListView view , it will go to another activity(SubListView.class), and I can't see the tabs in that activity. Only contents of that view will be displayed there. How can I show these header tabs in that view also?

View 2 Replies View RelatedCurrently I have a TabHost implemented with 3 tabs each containing a separate activity.

View 4 Replies View RelatedI have a TabActivity and am going to have 3 or 4 tabs.In TabA, I would like to have an ExpandableListView, which will list products. I would like TabC to act as a sort of "shopping cart", probably with a ListView of itself. So, my question is: is there a way to interact with the TabHost from the Activity? I would like to be able to click a button inside of TabA and have it update and switch to TabC. Is this possible? Can I get the Tab's activities call it's parents methods?

View 4 Replies View RelatedI have 4 Tabs in a TabHost...let them be A,B,C,D.... now each one is just an index page and clicking on any of them shows a different activity...
The problem is that i need to start another activity wen user selects something from the content displayed in the tab... The other activity should also be displayed in the parent tab itself... is it by any chance possible or i'll have to try some other way around?

I followed the tutorial for this on the dev guide and ran into a problem. The tutorial only used three tabs, but I have a need for more. As such, the tabs resize and bunch up. I was hoping someone could tell me how I can make them scroll, like in dolphin browser when using multiple tabs.

I have to keep android:anyDensity="true" otherwise I've got a problem with re-sizing of the menus described here
As a separate question, my users can change the Locale within my app itself, I then "redraw" the menus using onPrepareOptionsMenu (Menu menu) to refresh the strings within the menu with the new language choosen by the user. Is there an equivalent for TABS (I have local strings within the Title of the TABS) or do I have to delete all the tabs and re-create them from scratch ?
We're in the process of writing an app that has 4 tabs: Map, People, Places, Events. The People, Places, and Events in the App show up as Icons on the map. By default the People, Places, and Events tabs each show a listview, custom rendered, displaying all the People, Places, and Events respectively.
Now, right now each of the tabs has as its content an Intent set to launch the corresponding activity. For instance, there is a MapTabActivity that extends MapActivity, a ShowPeopleListActivity that shows the people, and so on and so forth.
I see a lot of StackOverflow questions/answers saying that due to various limitations in the way the TabHost is setup, it's best NOT to use activities as the content of tabs. For instance, it's impossible to launch a new activity and have it take the place of the existing activity within a tab, whereas it's possible to switch out a View with a different view.
Now, I'm at a crossroads. We've (for better or worse) devoted a fair amount of time trying to get this app to work the way it's currently structured, with the Activities as the content of the tabs. When an icon corresponding to a Person, Place, or Event is clicked, it fires off a VIEW Intent on a URI corresponding to that object; this is picked up by an Activity that then shows the object. The same mechanism is at work both in the Map and in the individual lists. We really like the loose coupling this provides us; we just give a VIEW command and the URI to the person/place/event and it automatically brings us to the right activity. Granted, the activity that's launched covers up the tab view rather than appearing inside of that, but we were willing to live with this.
Here's an issue though: from the Show activity, we want to be able to go back to the map, centered at that person, place, or event. We can launch a new activity to show the map again, but now we have the map activity as the content of the tab, plus the show activity, plus the new map activity in the activity stack; given how resource intensive the map activity is, I'm guessing this is not the ideal way to go.
I guess my question is, is there a GOOD tutorial somewhere showing exactly how to do complex tasks with a TabHost? I've seen HelloTabWidget; I'm looking for something much more sophisticated than this. I'm worried that if we switch to the View based way of doing things, we'll have to do a LOT of housekeeping to intercept all the back events, try to switch out the views, etc., etc., as well as strongly coupling our program in a way we don't want.
