Question

i need to get the Activitys initialize , before anyone click on them . That is cause i have a video in one of them , and i need to have that Activity created to play the video from another tab (or activitys) .

I have this code to initialize the tab content but not the activitys into them :

//Init Tabs
Resources res = this.getResources(); 
TabHost tabHost = getTabHost(); 

tabHost.getTabWidget().setDividerDrawable(R.drawable.tab_divider);

setupTab(tabHost,MyInitActivity.class,res.getDrawable(R.drawable.ic_tab_icon),res.getString(R.string.tab_init));
setupTab(tabHost,MusicGroupActivity.class,res.getDrawable(R.drawable.ic_tab_icon),res.getString(R.string.tab_playList));
setupTab(tabHost,SearchActivity.class,res.getDrawable(R.drawable.ic_tab_icon),res.getString(R.string.tab_search));
setupTab(tabHost,VideoActivity.class,res.getDrawable(R.drawable.ic_tab_icon),res.getString(R.string.tab_video));

I have seen code like this to try it :

tabHost.setCurrentTab(number);

but that seems to not run when you change immediately cause when i do

Context context = getTabHost().getChildAt(3).getContext();

it throws to me a null exception.

Anyone knows how to do this?

ADDED

private void setupTab( TabHost mTabHost,Class<? extends Activity> activityclass,Drawable image, String tag) 
{

    View tabview = createTabView(mTabHost.getContext(),image,tag);
    TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview).setContent(new Intent(this, activityclass));
    mTabHost.addTab(setContent);
}

Thanks for all

I do the following in the onCreate() (say i have 4 tabs)

tabHost.setCurrentTab(0); 
tabHost.setCurrentTab(1); 
tabHost.setCurrentTab(2); 
tabHost.setCurrentTab(3); 

tabHost.setCurrentTab(Tab_I_Want);
