I am creating an android application in which uses tabs. There are three tabs which runs different activities. Activity which runs tab 1, has a button. I want to change content of Tab 1 by clicking on that button. But If I call another activity it doesn't start in tab1 but replaces tab.

Need an example of how to create/start a new activity from the main activity. I have a button click event on the main layout. Originally I just used setContentView(R.layout.secondactivity); which brings up the layout but I don't think that is correct since the secondactivity class is not instantiated at this point yet. I have looked for such an example and can not find one.

View 3 Replies View RelatedI am writing a application where I am dealing with 4 activities, let's say A, B, C & D. Activity A invokes B, B invokes C, C invokes D. On each of the activity, I have a button called "home" button. When user clicks on home button in any of the B, C, D activities, application should go back to A activity screen ?
How to simulate "home" button in this case ?
I have been reading a lot of comments on how it is more lightweight to use views instead of intents in setContent when using tabs.
Since I will be creating an app with tabs, I am trying to implement this instead of having intents inside setContent. However, I am having a difficult time looking for examples or straightforward tutorials on swapping the current view with another one.
Say I have TAB_A, with some entry fields and a button. When the user clicks on the button, a TextView will display "Hello, user!" in the same TAB_A. Of course this is an oversimplified example, but it will surely point me in the right direction.
EDIT: I have a tab called TAB_A with a button in it. If the user clicks on that button, TAB_A will now display "Hello, user!" instead of the button.
Here is a sample of my TabSpec.
CODE:..............
Where ShowButton and ShowHello are classes both extending LinearLayout. Both are initialized in onCreate like this:
CODE:.............
When the app first starts, the user sees the view showButton. When the user clicks on the button, I want the tab to change its contents to showHello.
The question then is: Is there any way to update the contents of the tabspec without using startActivity?
i have a problem with this new kitkat os. Before kitkat i could change between tabs by swiping left to right ir right to left to change tabs.Now it doesn't change.
View 1 Replies View RelatedI am developing an application that has a button whose color should change green color on focusing on the button and the color of button should change to red on clicking the button. I am using setBackgroundResource() in the onClick and onLongClick listeners. Though it changes the button color, it also changes the button shape by making it look like a rectangle.
How can this be solved?

Actually i want to show the list view again from 1st element. is tabs refresh automatically or we need to do it programmatic?
View 1 Replies View RelatedI have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?

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.
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?
CODE:.................
I have Activity based tabs i.e i have used TabActivity,tabhost etc Now when we switch between the tabs, for the 1st time the oncreate is called and then after the onResume methode is called I want to know what event/function, of the activity, is called when i click on the the tab which is already selected.

I would like TabC to act as a sort of "shopping cart", probably with a ListView of itself. So, my question is: is there a way to interact with the TabHost from the Activity? I would like to be able to click a button inside of TabA and have it update and switch to TabC. Is this possible? Can I get the Tab's activities call it's parents methods?

View 7 Replies View RelatedI recently started Android programming and was working on my first program which displays a historic text document, sectioned by tabs via TabHost.I have limited my program to one activity and merely used setContent in my TabSpec's to switch between different XML views.The document has both unedited and corrected versions of the text for which I have built text views to accommodate. I wanted to implement the standard menu to have buttons to "view corrected" and "view original" and switch the content of the tabs which have changes (without altering the tabs or their indicators).I've read on the TabHost API and there is no way to edit existing tab content with setContent() of TabSpec; and AFAIK TabWidget only affects the actual tabs, not the content that is displayed upon pressing them.I've thought about creating a new class which extended TabHost and super() all of the original methods, while including one more which updated the mTabSpec list.

I want to provide a clickthrough on the list in a tab which opens another view. I need to open the new view within the same tab. I then need to provide a back button on the changed layout to change the view to original view.I have tried this. I am trying to access the tabSpec from main activity class [MainTabView] and set the intent as follows. Java: MainTabView.tabSpec1.setContent(new Intent(this, AView.class)); MainTabView.mTabHost.setCurrentTab(0); MainTabView.mTabHost.invalidate(); But this does not change the view immediately but changes it when I go to another tab and come to the starting tab. How can I make it to refresh it as soon as the content has been changed to another intent?
