I have issues with displaying a ListActivity in a TabActivity.
The super simple code below causes a crash.
CODE:.....................
I created a TabActivity with contains 3 tabs. Each tab's content sets different Intents.I would like to add a "footer" wich will appear on each tab. So I get TabActivity's FrameLayout and add it my footer view.Is it possbile to define where place the footer (with an attribute like AT_BOTTOM)? So contentTab dimensions are calculated according to this footer.

I would've tried to send a screenshot for this query if I could, but i'll try and explain.
I have 3 Tabs, each showing a separate Activity. Underneath those tabs (and above the activity display), I want to display a header. This header would probably be a Layout of some sort with a TextView inside it and a background 9patch.
Is this possible, if so how?
I create a TabActivity from Several ListActivities.
The lists are created from a cursor load in a AsyncQueryHandler. I have got no problem to load the content of the list.
After that I run an insert in the AsyncQueryHandler, and I meet the following error. The insert is done by the listActivity.
If I run my listActivity individually and that I do my insert, everything is find. Do know why ?

I'm having some difficulties getting the TabActivity to work.
Here's the implementation of the class:
CODE:..........
The problem is that I call this class from my main activity (which is a MapActivity if it matters) and when I do the TabActivity doesn't show. It registers the click on the option menu and it even starts the intent but the screen doesn't change..it just stays on the main activity and i see in the logs that the main activity gets resumed.
I call it like this:
CODE:...............
Like I said...there are no errors (the classes called from the tabs exist of course), just no actions. I put some log commands into the onCreate function in the tabactivity (as you see) and they all get written into the log...I have no idea what I'm doing wrong here.
I'm working on Android v1.5. I want to use a TabActivity with 6 or 7 or more tabs. However, I do not want to clutter my screen with so many tabs together. Hence, I'd like to be able to show, say, 3 tabs on the screen, and to be able to scroll to the other tabs. How may I achieve this? I could not find any example for this by Googling.

View 1 Replies View RelatedI have a TabActivity based class which has 3 tabs. All are ListActivities (but that's not important for this problem)
I'm updating the TabHost's TabSpec's to change the text on the tabs. This works fine and the ListActivities display correctly.
Iater on the execution flow I need to update the Text on the tabs from "Current Text" to "Current Text (3)", for example. I update the TabSpec.setIndicator() with the new text, and attempt to call invalidate() on the TabWidget (and all it's children). But the tab text refuses to update!
I have been trying to reuse the tutorial on the Android developer website about developing a TabActivity App but, unfortunately, it never worked, even when I constructed it the exact same way as it is described...
Using the debugger it seemed the problem came from the main layout.

Here is my main.xml:

I am trying to override the behavior of a TabActivity that has other Activities as children. I have made all of the children activities return false in onKeyDown so that the key will propagate through to the parent.However, this is not the case.The only key that is being recognized is the search key.Back, menu, and home are not being overridden.

I have a TabActivity, there are 4 tabs. In each tab I have put a single Activity. One of the activities contains a Custom List View which uses a CustomAdapter which extends the BaseAdapter.
I get this excpetion, when I try to open the tab containing this activity. It seems to be thrown at a point when probably the TabActivity is being re-drawn. Can anybody please suggest some alternatives, or solutions to avoid this problem.

I wanna put a "List" inside a TabActivity. by google and coder's guide, my work out "direction" is to create a "TabActivity" as MAIN and "ListActivity" then add it in the "TabHost" and turn out code something like (below) and fail:

I know i may need to spend more time on the BOOK and google for android development, but i also feel that the resource for android is quit scattered and not detail. (i'm a developer of C# for a few years, and it's more easilier to search for information)
I'd like to start a service from a tabactivity (I first tried in the activity launched for a tab but it seems taht there is a technical limitation).
So inside my TabActivity I defined a method named startService() which is quite simple:
> instanciate a new Intent > call the method startservice > Inside my "tabbed" activity (I mean inside a tab) I make a reference to the TabActivity and I call the method startService.
I have a TabActivity, each tab holds an activity. At some point I'd like to 'refresh' the tabs. I'd basically like to restart each activity in the tabs. I'm not sure how to do this. Calling:

I have got a TabActivity, which has 4 Tabs right now. The first Tab is a special Details-Tab, where the user could modify some data.
The problem is, that if I add a OptionsMenu for the Activity, that the OptionsMenu is appearing on every Tab.
I tried to check the current mTabHost.getCurrentTabTag() in the onCreateOptionsMenu but that changed nothing.
So, how to do that?

I'm trying to implement my own ActivityGroup to mimic TabActivity (without tabs) but I'm having trouble "closing" activities.My ActivityGroup has a ViewFlipper, each housing a separate activity's window.When I attempt to switch "activities" I call ViewFlipper.setDisplayedChild() on the view of choice.However, when I scroll up and down in the view of choice, the OTHER non-visible activities' views are responding to these actions, so it seems like I'm not successfully "switching" the activity fully.When I use a TabActivity to run this code, this doesn't happen; when I scroll up and down in one activity, I don't see any event firing from any of the other activities. I'm wondering what does TabActivity do to handle these activities as separate, individual entities?

View 2 Replies View RelatedThis question actually has two parts.
The first part:
I've been developing my first app for a couple of weeks now. I have 5 screens and everything seems well. However, I'm considering changing the app's navigation to a TabView.
I haven't delved much into it, but I'm hoping someone can save me a little bit of time. It seems that people don't generally place Activities inside each tab. They simply point the tab content to a View. This is where my major setbacks are. 1) I already have Activity classes full of code and 2) I can't quickly guess how the structure of an app using TabView looks. For example, where do I put the handler code for clicking a button on a View? Does it all just get dumped into the TabView Activity somehow?
What I would like is if you could please give me a quick synopsis of what I'm looking at doing, answers to any questions you think I may have, and point me toward some resources for creating TabView applications. A quick Google search really just shows me how to create a TabView Activity and add a couple tabs to it. The code doesn't go any deeper. For example, say I have a layout xml to show in one of my tab's content pane, where does the code go for clicking a button I have in that layout?
The second part:
I've added a TabActivity to wrap the Activities I currently have in. At the moment I have Activities populating the content of my tabs (though ultimately I'd like to do this in the most efficient fashion, which doesn't seem to be having Activities be tab content). I've noticed something rather annoying. My MAIN Activity is an Activity I wrote for my user to log in to their account. After logging in, they are taken to my Tab Activity. Here is what happens:
When I am on my Tab Activity and I "minimize" the app by clicking the Home button and then launch it again, I don't get taken back to the Tab Activity. I get taken to my log in Activity. Why? I don't have the launchMode of my Tab Activity set to singleInstance... or is it singleInstance by default? How can I make the app re-launch showing the Tab Activity (ideally by setting some parameter, assuming I'm doing something wrong, and not having to save this data off somewhere and reading it and programmatically telling it what to go to)?
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.
CODE:..................
I have an activity which extends TabActivity and implements TabContentFactory. For simplicity's sake I'll limit the problem to 1 tab.
In onCreate() I do this:
CODE:..........
In createTabContent:
CODE:...........
So far, so great. I get the tab, the layout is displayed.
I also have a button in the layout, so I do:
CODE:.............
And then I subscribe to it's click event:
CODE:..........
Now, here's the problem. I click the button and nothing happens. I can for example execute the following code from elsewhere:
CODE:.............
And the button will get disabled, but when I tap it (in its *enabled* state) - nothing happens.
If I'm not, could it be that I have another tab, where the another inflated copy of the same layout is displayed? However, in this layout's button's OnClickListener nothing happens as well.
I want to create a TabActivity that works like a browser.
When the activity is created, it has two tabs: "Tab1" and "Add Tab". When the "Add Tab" is clicked, it should Add a new tab.
Tab 1 | Add Tab
==> Add Tab is clicked
Tab 1 | Tab 2 | Add Tab
==> Add Tab is clicked
Tab 1 | Tab 2 | Tab 3 | Add Tab
All my tabs contents are instances of the same Activity.
I have created a tab activity and render a button widget over it using setcontentview I wanted to setClickListener for that button . i m able to setLongClickListener , let me know how can I implement View.setClickListener on tabActivity so that I m able to set setClickListener on button widget inside tab activity.
