Hi
I have a Activity that uses an array adapter to show 4 lists each under a
tab (as in the code below). Each item in the list is a CheckedTextView as in
the layout file at the bottom. How do i set individual items "checked" in
one of those lists?
Thanks in advance.
public class TagPicker extends TabActivity {
TabHost mTabHost;
StoreListAdaptor allListAdaptor, analogListAdaptor, digitalListAdaptor,
stringListAdaptor, eventListAdaptor;
ListView listViewAll, listViewAnalog,listViewDigital , listViewString,
listViewEvent;
SmartList smartTagList;
ListOfActiveTags listOfActiveTags;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tagpickerlayout);
smartTagList = SmartList.getInstance();
listOfActiveTags = ListOfActiveTags.getInstance();
mTabHost = getTabHost();
Resources res = getResources();
mTabHost.addTab(mTabHost.newTabSpec("allTab").setIndicator("All",res.getDrawable(R.drawable.ic_menu_tags)).setContent(R.id.alllist));
mTabHost.addTab(mTabHost.newTabSpec("analogueTab").setIndicator("Analogue",res.getDrawable(R.drawable.ic_menu_clock)).setContent(R.id.alist));
mTabHost.addTab(mTabHost.newTabSpec("discreteTab").setIndicator("Discrete",res.getDrawable(R.drawable.ic_menu_light)).setContent(R.id.dlist));
mTabHost.addTab(mTabHost.newTabSpec("stringTab").setIndicator("String",res.getDrawable(R.drawable.ic_menu_tags)).setContent(R.id.slist));
mTabHost.addTab(mTabHost.newTabSpec("eventTab").setIndicator("Event",res.getDrawable(R.drawable.ic_menu_flash)).setContent(R.id.elist));
mTabHost.setCurrentTab(0);
