Android :: Existing Patches For Tabwidget To Allow Tabs On Left-hand Side?

Aug 16, 2010

My 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

Android :: Scrollable Tabs - Dolphin Browser When Using Multiple Tabs

Jun 19, 2010

I'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.

Android :: TABS In 2.0 Vs 1.5 - Rounded Corners TABS

Feb 27, 2010

I simply use the tabwidget :

CODE:..........

Why are my tabs so uggly in 2.0 (no more rounded corners as in 1.5/1.6) ?

ugly tabs here

=>

This was better

What should I do now to show "rounded corners" TABS to Nexus One (for exemple) users ;-) ?

Is it because of the following manifest lines :

CODE:................

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 ?

Android :: Tabs - MapView - Activities Within Tabs

Oct 19, 2009

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.

Android :: TabWidget In Light Theme

Dec 15, 2009

I 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?

Android :: Get Reference To TabWidget In Java Code

Mar 9, 2009

In 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'"

Android :: Why Do I Get Null Pointer Exception From TabWidget?

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.

Android : TabWidget White Foreground Color?

Mar 30, 2010

I 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?

Android :: Tabwidget Graphical Showing A Thick White Line?

Apr 21, 2010

Having 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?

Android :: View A TabWidget In Layout Editor It Crashes - Buggy

Jun 6, 2010

It 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.

Android : TabWidget Activity Handling - Does It Create New Activity EveryTime?

Apr 27, 2010

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?

Android :: Resize Based On Orientation.

Feb 12, 2009

I need to have my view resize itself based on the orientation. After extensive googling (maybe i was using the wrong terms) I could find nothing telling me how to detect when the orientation was changed. Here is my layout file: how do I have it automatically resize itself? I want each item (the EditText and the WebView) to fill half the screen (not counting the title/notification bars). I set the height to absolute and not wrap_content because wrap_content defaults to 1 line for EditText and nothing for WebView. and fill_parent has the EditText on top of the WebView.

Android : How To Detect A Layout Resize?

Nov 13, 2010

Dianne Hackborn mentioned in a couple threads that you can detect when a layout as been resized, for example, when the soft keyboard opens or closes. Such a thread is this one... http://groups.google.com/group/android-developers/browse_thread/thread/d318901586313204/2b2c2c7d4bb04e1b However, I didn't understand her answer: "By your view hierarchy being resized with all of the corresponding layout traversal and callbacks." Does anyone have a further description or some examples of how to detect this? Which callbacks can I link into in order to detect this?
