Currently I have a TabHost implemented with 3 tabs each containing a separate activity. My question is how do I switch between tabs from within one of the activities that is located inside the tab host. I've looked everywhere and have been unsuccessful in finding a real answer to this problem.

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?

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?

I have Activity based tabs i.e i have used TabActivity,tabhost etc Now when we switch between the tabs, for the 1st time the oncreate is called and then after the onResume methode is called I want to know what event/function, of the activity, is called when i click on the the tab which is already selected.

View 2 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?

What should I use? BroadCastReciver or What? If anyone have any good idea please help on me.
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?
Is it necessary to use TabActivity for displaying Tabs. I want to display tabs from Activity.

I am creating an android application in which uses tabs. There are three tabs which runs different activities. Activity which runs tab 1, has a button. I want to change content of Tab 1 by clicking on that button. But If I call another activity it doesn't start in tab1 but replaces tab.

View 1 Replies View RelatedI'm currently working on my first android application. I am using a tabbed layout for my application. 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.
I'm currently working on an application, designed around a TabActivity.Tab1 has a button and I would like when the user click it, it switches to Tab2.

View 1 Replies View RelatedIt seems like every example I can find of switching between Activity's involves creating an Intent and passing in the context of a View via an OnClickListener associated with a button.But what if you just decide you need to switch Activity's? In my case, a Preference value is causing an Activity switch. How do you create an Intent that can cause an Activity switch without an associated OnClickListener?
View 4 Replies View RelatedThis post probably shows my ignorance of Android coding, but here goes. I have a sample app I am developing which starts by extending Activity. I have a main.XML layout which works great. On a button click from the main layout I'd like to load a ListView. I think I understand how to use ListView and seed data into it. I have created a new layout which contains this ListView. I am confused, however, how I switch from a regular Activity to a ListActivity so I get the convenience methods like setListAdapter()? Should I be starting with a ListView, and then drawing the other view on top once the app starts by inflating the layout and using it? If not, how do I create a ListActivity object inside my app, and where should I create that? If you have a sample application or tutorial that shows how to do this, I would appreciate it.

In the emulator, the program behaves like it should. However, when I put this application on my phone (Nexus one), it doesn't switch to the new Activity when I touch the screen after I take a picture. If I touch the screen without taking a picture, it switches to the new activity. I can't figure out why my phone won't switch to the new Activity after taking a picture.
does anybody knows how to launch a new activity with rotation animation.That I would like to know if there is a way to do the same but instead of image, i will be activity (whith new layout).

I have created a TabHost and in 1 of the tab, I have added the content using
mTabHost.addTab(mTabHost.newTabSpec("tab1")
.setIndicator(getString(R.string.dialerIconLabel),

.setContent(intent));
Is it possible for me to switch the content's activity programatically after I called 'addTab of TabHost'?
I have a basic calculator app I'm making. Two activities, the main one and ResultView.
I've made it where I click a button on activity A to go to activity B. The log says activity B is started and "displayed" successfully, the title for the new activity loads, but the body does NOT show. I added a simple Text view with static text.. see the result.xml at the bottom. I also tried inserting information programmatically, but that didn't do.
When I debug the program, I tried putting breakpoints as the activity is called with startActivity() as well as on the first line of the onCreate method within the ResultView class (my activity "B") but the program never hits the second breakpoint. In fact, it looks as if Looper.class is called in the end.
This bit of code is placed in the button handler on acitivity A:
CODE:........
The activity is in the manifest, within the "application" tag:
CODE:....................
If more info is needed, let me know...in short, "HELLO WORLD" does not display at all.
In my TabActivity the user may be asked to switch to browser activity for OAuth phase, and if the phase takes too much time, my activity will be killed. After the user switches back to my activity, its onCreate() method is invoked again and tabs are recreated.
So I would like to know if there is any simple way to switch back to previous tab, and keep the tab as what it was. For example, one of the tab views contains a ViewSwitcher child, and I want to switch back to the switched view after recreating the activity.
