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 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:

Removes the tabs, but the activities still seem to be in alive, in limbo. How can I get them to really quit?
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 am developing an application and as part of it I would like to show a tabactivity and use the contact activity to let the user see,modify,or call a specified contact.
My code is this:

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 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 would like to access the public method of an Activity run by a TabActivity using: Code...
Basically, what I what is to let the parent Activity call a method in child Activity in order to do something. Is this possible?
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.
I want to have a class "Utils", that will have several methods used all over my code. For example, I have a top bar with a textview and two ImageButtons that must display different texts and icons on different activities.I created the class Util, but it doesn't extend Activity. The problem is that if it doesn't, findViewById isn't there, can't find stuff etc.

I managed to create a functional version of the app by having the "Start" button call a new layout in which a new onclick listener is defined.
This doesn't seem clean to me that I@m defining a new onClick listener for each Layout I use and wonder how the correct way would be to create individual pages (including my "About" and any other screens I implement).
Official android dev website says that:You can implement your tab content in one of two ways: use the tabs to swap Views within the same Activity,.....http://developer.android.com/resources/tutorials/views/hello-tabwidget.html
I just wanna use tabs to swap views, no more than one activity. is there any sample code?
For a rather crazy reason I am trying to pass a linear Layout from one activity to another. Should I use an intent extra for this? What would be the right way to create a Linear Layout in one activity and then spawn a new activity using that linear Layout.
View 8 Replies View RelatedI want to find the dimensions of the various views in my layout. My understanding is this can only be done after layout is completed since layout is somewhat dynamic. So, after the activity calls setContentView() and then returns control on the main thread to the OS so that layout can occur, how do I get a notification that layout has completed so I that I can query the views for their dimensions? On a related topic, can I find out the status bar's height or least the screen's full size (from which the status bar's height can be calculate by subtracting my window's height)?

I'm plugging my phone into my computer (Windows 7), but when I try to view sd card contents I am getting "Please insert disk" notification. It recognizes that I have it plugged in and it charges, but I can't access any of my phone files. I was able to do this 5 hours ago and since I've had this phone, this has never happened before. Before when I plugged my phone in I instantly got a pop up asking if I want to see files, but now I can't even access them without that. No idea where this new problem just came from.

View 4 Replies View RelatedIs it possible to add a view dynamically that overlaps other views in the layout. I have Linear Layout defined for the activity. As part of the Layout I have a custom View. The content changes dynamically and sizes appropriately based on the content size, with fill_parent for width and wrap_content for height. But what I want is, dynamically take over the full screen and then based on a click go back to the normal mode. Is there a mode to display a view where - in it can overlap all other views in the layout?

I have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).

I'm trying to create a simple text based game in which I ask a question based on a movie. The list of movie's is in a text file which I've included in res/raw. So basically I want to have a default string, say "Who acted in", followed by the name of the movie. Could I have the first string (along with a submit button etc) in my res/layout/main.xml file, and follow that with the movies name, after I've extracted it from the text file in my activity, or does the layout have to be defined in one place only?
