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 ?

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.

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.

Suppose i m on 4th tab and dragged the list view to the last position and after that i click on 3rd tab and again when i go to 4th tab it is not refreshing and showing me the last visible screen. Actually i want to show the list view again from 1st element. is tabs refresh automatically or we need to do it programmatic?

In android, ImageView is a rectangle by default. Is it possible to make it a rounded rectangle (clipped off all 4 corners of my Bitmap to be rounded rectangles) in the ImageView? If yes, can you please tell me now can I do that?

The following code snippet draws a red rectangle:
RectF rectangle = new RectF(50, 100, 100, 50);
Paint paint = new Paint();
paint.setColor(Color.RED);
canvas.drawRoundRect(rectangle, 0, 0, paint);
However if i change rx and ry both to a positive value, say 5, than nothing is shown. Any ideas?

I've seen some chatter about this, but nothing definite. Is there a way to put the tabs in a TabWidget to the bottom of the screen? If so, how?
I've tried the following, but didn't work:
a) setting the tabwidget below the framelayout
b) setting the tabwidget's gravity to "bottom"

I have tabbed activity with tabs at the bottom. The labels of each tab are getting clipped unless I set the TabWidget too high (~60dip). My tabs don't have any icons. What is the trick to get the labels centered in TabWidget?

I'm working on adding a tab to an application, but the last two tabs (regardless of order) are launching the same activity. If I go down to two tabs they both work correctly, but when I add the third the last two result in the same activity launching.

I'm trying to build a tabs view for an Android app, and for some reason I get a force close every time I try to run it on the emulator. When I run the examples, everything shows fine, so I went as far as to just about copy most of the layout from the examples(a mix of Tabs2.java and Tabs3.java), but for some reason it still wont run, any ideas?
Here is my code(List1.class is a copy from the examples for testing purposes). It all compiles fine, just gets a force close the second it starts:

I have a auto-complete textbox in which the user makes a selection. From here I want to load a tabbed layout which is based on the user selection. The problem is I cant figure out a clean way to pass that selection to each of the tabs. At the moment I can pass an intent to the 'tabhost' activity and then pass to each child activity explicitly, however this just seems like messy iterative code to me! So basically how can I pass my intent data bundles to the tabs activities cleanly & efficiently! Psuedo code is also very welcome.

Where I can find a simple tabs example?
The Android Developers Hello Views Tab Layout example only details how to use separate Activities for each Tab.
I would like to use tabs to extend a screen of settings without scrolling, i.e. there are too many options for a single screen, so I'd like to split them over two tabs, but still handle them in the same Activity.
Each tab can refer to a separate layout file if that is how it needs to be done.

I'm working on an Android application with an activity that uses a tab layout. There are two tabs which switch between the content being shown in a ListView below.
This means that the two tab specifications point to the same ListView for content, R.id.main_list:
CODE:..................
This somewhat works - if I switch to tab #2 and back to #1, I can see the ListView and my database code gets the right data based on the selected tab. However, when the activity launches, the ListView can't be seen before tabs are changed. This is obviously a problem.

My first page contains 3 tabs. I want to retain all these 3 tabs through out my entire application. That means I want to see these 3 tabs in every view. For example : I have 3 views. First view is Main.class. It contains 3 tabs (Home tab, Favourite tab, settings tab). When I am clicking any one tab (Ex: Home Tab), it shows the contents of Home.class (a ListView) below these tabs. But when I am clicking the ListView view , it will go to another activity(SubListView.class), and I can't see the tabs in that activity. Only contents of that view will be displayed there. How can I show these header tabs in that view also?

I have created an apk which has activities. I have included tabs in my program through which the user can select the required activity. But my main problem is that i couldn't find a way to display the tabs throughout the application. For example, on clicking a tab the corresponding tab opens. But when i click on a button the activity is displayed but the tabs are not getting displayed. I have included a tabHost in the program to display the tabs for various activities.

I'm new to android development but I have run through various tutorials and am slowly grasping how to develop apps. I modified the Tab Layout tutorial on the android dev website to fit my needs, and now I need to add a list on to each tab I have created. there are a total of seven tabs and each will have it's on specific list. If someone could point me in the right direction to adding a list per tab that would be great. Each tab has it's own class file, would I add the list items as strings in the strings.xml then add code to each tab's class file in order to populate the tab? This was the only thing I have found so far, but it hasn't worked.

I have a tabbed applicationen setup. I like to keep the tabs visible at all times and work with its subactivites as 'more or less' standalone application threads.Within one or more of these tab subactivities, I'd like to start its own sub-activity, which should not hide the root tabs.Whatever I've found will call ctx.startActivity() which works, but will hide the tabs by using the full screen.Is there a way to limit the sub actitivies to a parent activities bounds, and keep (in my case) the rot Tabs visible? Where shall I look?

I have an app with 2 tabs, the first is a listview, and the second I'm trying to make a TextView. The problem is I have no idea on how to get the TextView to show up. The listview is working, but I can't get anything on the TextView at all. I tried using the Hello, World to try to work with the text into the tab, but I can't figure it out.
