Answer 1

First of all you have to understand what is a Fragment and how to instantiate it and how to send to it data (you should look the guide dedicated to Fragments and the documentation for Fragments here).
Then you have to do 2 things :
Create your custom list fragment, I suggest you to look at the android documentation of ListFragment and create a class that inherits from ListFragment.
public class CustomListFragment extends ListFragment {
// your code here to add content
}
Modify your TestFragmentAdapter to instanciate your new CustomListFragment when you are in the first page (see example below)
public class TestFragmentAdapter
extends FragmentPagerAdapter
{
protected final Class[] CONTENT_CLASSES = new Class[] { CustomListFragment.class, TestFragment.class};
protected final String[] CONTENT_TITLES = new String[] { "List", "Test"};
public TabAdapter( FragmentManager manager, Activity context )
{
super( manager );
this.context = context;
}
#Override
public Fragment getItem( int i )
{
Class targetFragmentClass = CONTENT_CLASSES[i];
Bundle args = new Bundle();
// add your args here
Fragment targetFragment = Fragment.instantiate( context, targetFragmentClass.getName(), args );
return targetFragment;
}
#Override
public int getCount()
{
return CONTENT_CLASSES.length;
}
#Override
public CharSequence getPageTitle( int position )
{
return CONTENT_TITLES[i];
}
}
