A working code:
public class UbikIMActivity extends TabActivity
[...]
@Override
protected void onCreate(Bundle icicle)
{
super.onCreate(icicle);
[...]
/* Create tabs */
Resources resources = getResources();
TabHost tabHost = getTabHost();
/* Create home tab */
TabSpec tab = tabHost.newTabSpec("home");
tab.setContent(new Intent(this, HomeTab.class));
tab.setIndicator(null, resources.getDrawable(R.drawable.home));
tabHost.addTab(tab);
/* Create contact tab */
tab = tabHost.newTabSpec("contact");
tab.setContent(new Intent(this, ContactTab.class));
tab.setIndicator(null, resources.getDrawable(R.drawable.contact));
tabHost.addTab(tab);
[...]
I don't use any XML for the TabActivity (using default tab activity
layout) but you can call setContentView with a layoutID that must have
special ids:
* a TabHost tag with the id: @android:id/tabhost
Inside the TabHost (which is a layout) you shall have:
* a TabWidget with the id: @android:id/tabs
* a FrameLayout with the id: @android:id/tabcontent
Hope that will help.
