When a TabWidget is using intents to designate the target Activity for each tab, is there any special handling of those Activities on the Activity Stack outside of the default operation? For Instance, if my app has tabs A, B, and C, and I click them in this order--A, B, A, C, A, B--how will the Activity stack change? My understanding of the default operation, if startActivity() is called each time on the intent, would have the Stack keep loading up new instances of the activities: A, AB, ABA, ABAC, ABACA, ABACAB It's hard to believe that's how it works though... Seems like it would be a waste of resources and could be endless. Can anyone tell me how this will actually work?
View 2 Replies View RelatedI created an Activity which allows navigating between pages with a couple of Buttons (Previous and Next). When the user clicks one of the buttons, the Activity (same) needs to be "refreshed". In order to do this, I set up the buttons to make a call to onCreate(this); after they set up the other stuff that the activity uses for the paging to work. And it is working so far, but I'm wondering if there is a better way. Is there?

View 1 Replies View RelatedI have an application that targets the 1.5 framework and uses the default light theme. When using a tab widget with this theme, the tab images are barely visible, and the tab captions are quite impossible to discern, except for the currently active tab.In the default dark theme these tabs come through quite clearly, but this is not a solution I'd be very happy with. Is there a simple setting I can set, that sets up the tab widget for better visibility in light themes, or would I have to tamper with images and text styles manually?

As the title, I want close the TabWidget where some tab is selected.
I have a little problem, I'm doing landscape layouts and I can't resize the Tabs, which are huge like on this .

View 1 Replies View RelatedIn my layout xml, I have: <TabHost android:id="@+id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent">
<TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/>
</TabHost>
My question is how can I get a reference to TabWidget object. I tried this: mTabWidget = (TabWidget) findViewById(com.android.internal.R.id.tabs); but this won't compile since 'com.android.internal.R is not visible. And then I try change the id to android:id="@+id/tabs" but I get a run time error saying: "Your TabHost must have a TabWidget whose id attribute is 'android.R.id.tabs'"
I'm writing an android program in which I have an activity that uses tabs.Anybody have any idea how I can get this content into a tab without crashing my application? My actual program is more complex and has more than one tab but I simplified it down to this in an attempt to find out why it's crashing but it still crashes and I don't know why.If I don't use LayoutInflator my program doesn't crash but I don't get any content either, just tabs.

View 1 Replies View RelatedI don't know what I did but for a period of time my TabWidget had white colored tabs which looked really nice. I never set a theme or background/foreground color in my project at all. The next time I compiled it it reverted back to the gray tabs. My application is using the default dark theme. Even if I set the application theme to light, the tabs are still gray. So obviously it was something else that changed the tabs' color. Anyone know how to do this?

View 2 Replies View RelatedHaving just moved to an Android 2.1u1 HTC Desire from an Android 1.5 HTC Hero, I've noticed that there a weird behaviour from TabWidget in that it shows a thick white line under the tabs instead of what I think it should do. Difficult to explain so here are two URLs: http://android.esstec.co.uk/images/how_it_should_be.png http://android.esstec.co.uk/images/what_it_is.png Initially the tabwidget looks like the first picture but when you do anything with it (change tabs for example), it looks like the second. These screenshots are from the Google provided API demos so I don't think it's my code, but I wanted to paste here before filing a bug. Anyone got any ideas?
View 2 Replies View RelatedIt seems that Android is very buggy compared not only to the iPhone, but to pretty much any other software. It's not just minor bugs either - pretty much every developer will come across many serious bugs. Some examples:
- When you run the "sdk setup.exe", the very first thing that happens is that it informs you that it can't connect using https, so you have to change the options to use 'http' instead. This appears to be a bug in the .exe rather than any kind of user issue because the https url works fine in the browser and this error seems to affect everyone. Sure, it's trivial to work around (just do a google search and you figure it out in 5 seconds), but the user shouldn't have to do that. It makes it look unprofessional.
- When you view a TabWidget in the layout editor it crashes.
- Every time you run an app in the emulator, it starts off with the screen locked so you need to press the Menu key.
- Various socket bugs (or perhaps all the same bug) related to IOException not happening. Even something as simple as just trying to connect to a remote host that is not listening will cause it to hang instead of immediately returning an error.
All of these bugs have been logged for months (some by me, some by other people) with no indication of any fix.
At the moment I'm just using the emulator, but I'm wondering if the phones themselves are this buggy or if all the bugs are just in the development environment and emulator.
In my TabHost activity, I want to show an ImageView below the selected tab (the ImageView overlaps the tab content). What would be the best solution to do this?
View 2 Replies View RelatedMy employer is having me work on an android application with very specific UI requirements. Specifically, we need an interface that looks exactly like a TabWidget interface. However, having the tabs on the left hand side is an absolute must. We aren't going to be deploying this application to any android phones, its for an in house device, and as such don't have any problem violating any design considerations that the android platform might have.
We already have a working prototype that hacks together the functionality we need using a combination of focus listeners and list views. It isn't pretty, and we aren't very confident in it just yet, but it works for the time being.
What we'd really like is to throw all of our prototype UI code away in exchange for using the built in TabWidget. However, since TabWidget is hardcoded to only work with the tabs on top, this isn't really an option.
So, we are hoping that someone out there has a patch, or set of patches, or perhaps a custom class, that handles the TabWidget functionality with the tabs on the side instead?
The relevant code for the TabWidget is here: http://www.google.com/codesearch/p?hl=en#uX1GffpyOZk/core/java/android/widget/TabWidget.java&q=android%20package:git://android.git.kernel.org%20lang:java%20tabwidget&sa=N&cd=1&ct=rc
And the specific function that is hardcoded for being tabs on top is

I'm trying to develop a small app, that can retrieve GPS coordinates, and store them, so I can retrace the path I took. The thing is, the GPS on Android emulator is kind of screwing around with my nerves... First of all, the Mock Position system doesn't work, so I'm manually fixing the coordinates with telnet "geo fix" command. Second of all, the location listener seems to not be refreshing. I'm lauching the app, fixing a first set of coordinates, and observing the response I expect. But when I push a second set of coordinates, the app simply doesn't react.
I tried a lot -big lot- of ideas on this, and I'm kind of running short...
By the way, I'm developping on Eclipse with ADT, and the SDK for Android 1.5 (French HTC Heros are still with Android 1.5) so that I can use my own app.
Here's my code (just the coordinate retrieval part) :

I have a view with a spinner. The activity starts another acvitity with a popup where I add or delete values that the parent shows in the Spinner.
So, in onActivityResult() I refresh the content of the Spinner so that it reflects any additional or deleted values, by calling my fillSpinner() method.
The parameter to this method is the previously selected value:
CODE:..........
When I open the Spinner, it contains the correct list (i.e. it was refreshed) and the correct value is selected. However, the Spinner control itself (in its closed state) does not show the selected value, but the first in the list.
When I step through the code in the debugger, the Spinner value is correct before and after I call setSelection() (and it is always called with the same correct id). However, since I cannot step out of the event, when I resume the execution after a short moment the value in the Spinner changes.
In other words, the spinner's displayed string is changed and is different from the selected item when I return from my popup activity.
I have a listview that's populated by rows that get their data from a web server. It all works totally fine except I want to have a refresh button to re-download the data. I'm getting the data through an asynctask (getting the data in doinbackground) and then setting the listadapter in onpostexecute. All I do to run the asynctask which should take care of everything is run
new PopulateListTask().execute();
However, in my optionsSelect method, creating a new asynctask just like I did in oncreate doesn't do anything. It doesn't even enter doInBackground. I've tried using listView.invalidate() and listView.invalidateViews(). Is there some special way I'm supposed to repopulate a listview?
My only guess is that since I'm using a custom adapter, my getView method is creating some kind of error, but that wouldn't explain why it's not even entering my asynctask's doInBackground method. Thoughts?
Posting some code. This is a trimmed down version.
CODE:............
I'm getting this in my logcat when executing my asynctask the 2nd time. Any idea what it means? I tried googling to no avail.
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!

View 4 Replies View RelatedI'm running into some issues here with my app. I have 4 tabs run through a tabActivity. One tab sends an intent and run my ListActivity that populates the screen from a simpleCursorAdapter. My problem is that when I change back to this tab, after the first time its run, the list never refreshes regardless of the changes made to the database via other tabs. Is there something I can call from onTabChanged to refresh my ListActivity?
View 3 Replies View RelatedIn the Settings menu, there is an "Auto Refresh" option which you can set to "Never," but there is also a "Ticker Refresh" option which you can't turn off. What do each of these things control? Is the Auto Refresh just for when the app is running? Does it affect the widget at all?
Does the Ticker Refresh option only affect the widget? Does it have any effect if the widget is not being used on any homescreen?
My problem is when I want to refresh data in ExpandableListView while being in that current activity. I create adapter and when I want to add new data to list I call again constructor of that adapter(it is my private variable) with all new data....and then I call onContentChanged() method to redraw my list.
But what happens is that I cant expand my list any more...like it is blocked or something and logcat isn't saying anything...
This is the code that i call after setting new data in arraylists and maps:
CODE:....................
I created a ListView that contains a row which in turn contain text and a button. The idea is to have the button function as a delete button to remove the row from the list as well as the database. I order to do this I created an adapter to handle the button click. This code is below. Deleting the database record works fine, but I have not yet succeeded in refreshing the ListView so the record will no longer be displayed.
public class FeedArrayAdapter extends ArrayAdapter {
private ARssEReaderDBAdapter dba;
private String TAG = "FeedArrayAdapter";
private View v;
private ListView feedList;..............
I've got an App Widget that gets updated (er... I try to update it) with the following chunk of code: ComponentName thisWidget = new ComponentName(context, MyAppWidgetProvider.class); AppWidgetManager manager = AppWidgetManager.getInstance(context); manager.updateAppWidget(thisWidget, remoteViews);
The problem I'm seeing is that it the user interface is updating always one behind (i.e. using the previous remoteView to update the user interface). So, i make that call with a certain configuration in remoteViews, and it doesn't reflect in the UI until the next time I call it with a different remoteView. I know this is kinda vague and I don't have a lot of details here, but i was wondering if I'm missing something very obvious.
I want code for refershing my page automatically when i click on any button.For Ex I have a people page In that page i delete people from total peoples using one button but that selected people is not deleted immediately That means the People page is not refreshing.So,I want code for refreshing that page.Give me any suggestions.Thanks in advance
