[android-developers] Re: Adding content to a tab view dynamically
Thanks for the help. I didn't actually manage it this way, but somehow i saw
the *createTabContent* function from *TabContentFactory* (which i was
already using actually) is called every time a tab is selected, not just at
its creation. So i make a completely new *LinearLayout* inside the tab and
just return it as the content, being able to do whatever i want in that *
LinearLayout*.
Thanks for the help again.

[android-developers] Re: Adding content to a tab view dynamically
This seems a bit goofed up to me. First off, the FrameLayout holding
your tabs should initially be empty. the TabHost will manage filling
it in with the contents of the tab you've selected.
addTouchables is very certainly not what you want. You want to use
addView() but make sure that the view you get with getCurrentView is
what you expect. Make one tab have a with android:id="@
+id/foobarbaz", then check that getCurrentView hands you a view for
which findViewById(R.id.foobarbaz) succeeds to find your
LinearLayout. If not, try getCurrentTabView (there is nod
ocumentation, so we're just stabbing in the dark here). The other
solution is to better abstract the tab content in question and let the
abstractions manage themselves. You can do this by separating the
content of each tab into its own Activity and properly isolate them
that way. When you click some button in Activity A, A can manage
adding views to its layout entirely on its own.

[android-developers] Re: Adding content to a tab view dynamically
Ok, great, thanks for the help! Here's the relevant code from the XML:
*http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
*
And here's how i tried to add something:
*private void addItem(){
CheckBox c=new CheckBox(this);
ArrayList a=new ArrayList();
a.add(c);
tabs.getCurrentView().addTouchables(a);
}*
*tabs* is the TabHost object.
Did i get it wrong with the *addTouchables*? I couldn't find any better
method. Also, instead of *getCurrentView* i tried *getCurrentTabView* and i
also tried a lot of casts applied to children and children of children and i
couldn't get an effect.
(I know the function above is called when it should be - i confirmed it
during debug..)
Thanks,
Teo

[android-developers] Re: Adding content to a tab view dynamically
Actually my mistake. getCurrentTabView might just get the view of the tab you have selected (not the contents of the tab). Try getCurrentView. Post sample code if you can't get it working and I will explore further.

[android-developers] Re: Adding content to a tab view dynamically
Do you mean to add a new tab or simply dynamically adjust the View hierarchy in a particular tab? If so, getCurrentTabView will work to do what you need. Just modify the view hierarchy found there. Do realize that you are getting the root-level View of the tab, so you must search within that using View#findViewById to locate the actual view you're looking to modify.
