Android :: Tabbed Application With Location Listener Implemented In TabActivity TabHost

Sep 25, 2010

I have an application that has a tabActivity and 3 tabs. all off the tabs use a location listener and work with locations. i implement onPause and onResume for every tab to remove and start listening for location accordingly. is this the right way to go? i had another idea to work with and that was implementing a location listener to the tabActivity and doing broadcasts to the child tabs with the location, but it seemed more complicated.

The problem with my current solution is that whenever i switch tab i lose the location i got in the previous and i cant use getlastknown location because i dont want the last location on start of the application.(does this make sense?) what can i do to solve this problem. a thing that will work better will be to have one variable that will hold the last location from the onLocationChanged and i can observe its changes and call methods onChange.

Android :: Emulate Back Button In Multi-view TabActivity

Jun 5, 2010

I have a TabActivity with several tabs. Each tab corresponds to a specific view, and those views may further switch to other views. For example, one of my tabs displays RSS feed list, after user clicks one of the RSS feed, it will switch to a view displaying a list of articles, and after user clicks one of the titles, a full article view will be displayed.I'm going to add support for "back" button in my application. For instance, in a full article view, after user presses the "back" button, it should switch back to the article list view. And if user presses it the "back" button again, my application should switch back to the feed list view.My idea is to maintain a Stack<View> during navigation, and every time user presses the "back" button, the program will pop a View out of the stack, and set it as the current view. But I would like to know how to set current view in TabHost.

Android :: Same Listener For List And Button

Nov 22, 2010

In my application pressing a list row or a button means executing the same commands. My problem is that the list and the button have different listeners (AdapterView.OnItemClickListener vs. View.OnClickListener). How can I add the code for the 2 views (as a listener) without having duplicate code.

Android : Listener - Back Button - And OnDestroy

Mar 13, 2010

I have an application with a single Activity implemented as a singleton (in the AndroidManifest). It implements a Listener I wrote. When the application is first run the Listener works fine. When I use the "home" button to minimize it, then open it again it's still fine.

But when I press the back button then run it again from the application icon, the Listener doesn't work fully. The code runs and the Listening methods are called as usual but none of the UI elements that are listening update. It requires a restart of the phone to get the listener working again after this point.

I know the "back" button doesn't really close the application, per se. But resetting the phone sure does! Is there a way to use the onDestroy() or similar method to call a function that actually closes the application? I'm asking because restarting the phone is the only way to get the listener back so I was hoping I could do that programmatic ally.

For example, my progress bar is a member variable of my Activity, but onCreate() I do "progressBar = (ProgressBar) findViewById(R.id.progress_bar);" Is this perhaps creating a separate instance of it or something?

Android : Want To Make A Listener For A Datepickers Cancel Button In Droid?

Jun 26, 2010

I'm using a datepicker in Android to let the user to choose the date. I want it to do one thing if the user picks a date and sets it (I have that working fine) and then to clear a certain text field if the user pushes the cancel button on the datepicker (open up the datepicker but then cancel out of it).

The way I've been trying is by making a code...

to attach the listener.

My problem is that the listener works if the user pushes the back button, but not if they push the cancel button. I tried using a dismiss listener, and that works, except for the fact that it goes off even whether I set or cancel the datepicker!

What do I need to do so something goes off if and only if I push the cancel button on my datepicker?

Android :: TabActivity Customization / How Is Possible

Aug 18, 2009

More of a TabWidget question I guess really...

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?

Android :: Getting The TabActivity To Work?

Mar 26, 2010

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.

Android :: TabActivity - Refreshing ?

Aug 18, 2009

I 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!

Android :: Simple App With TabActivity

Using the debugger it seemed the problem came from the main layout.

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.

Android :: Launching A Service From A TabActivity

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 tried to check the current mTabHost.getCurrentTabTag() in the onCreateOptionsMenu but that changed nothing.
So, how to do that?

Android :: How Does TabActivity Successfully Switch Activities?

Feb 10, 2009

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?
