How to make TextView inside ViewPager scroll vertically

[polygrimm]

I've got a ViewPager and a TextView inside it. When content of TextView is larger then it is visible on screen, there shall be possibility to scroll it vertically. But it does not do this automatically :(

 

Here is an xml for TextView

 

   <?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
	android:id="@+id/txText"
	android:layout_width="fill_parent"
	android:layout_height="wrap_content"
	android:background="#338877"
	android:padding="15dp"
	android:scrollHorizontally="false"
	android:scrollbarAlwaysDrawVerticalTrack="true"
	android:scrollbars="vertical"
	android:textAppearance="?android:attr/textAppearanceMedium" />

And here is an xml for ViewPager

 

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<android.support.v4.view.ViewPager
	android:id="@+id/vpPonkSwiper"
	android:layout_width="fill_parent"
	android:layout_height="fill_parent"
	android:layout_above="@+id/lbPonkFooter" />

<TextView
	android:id="@+id/lbPonkFooter"
	android:layout_width="fill_parent"
	android:layout_height="30dp"
	android:layout_alignParentBottom="true"
	android:layout_alignParentLeft="true"
	android:text="Footer" />

</RelativeLayout>

Here is an adapter:

 

public class PonkPageAdapter extends PagerAdapter
{
private int			 pagesCount  = -1;
private List<Ponk>	  data;
private App			 app;
private MockPersistence db;
private Activity		activity;
private TextView		currentView;
private LayoutInflater  inflater;

public PonkPageAdapter(Activity activity, byte section) {
	this.activity = activity;
	this.app = ((App) activity.getApplication());
	this.db = app.getPersistence();
	this.section = section;
	this.data = db.findPonksBySection(section); // new LinkedList<Ponk>();
	this.inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
	//
	this.pagesCount = db.countPonksInSection(section);
}

@Override
public int getCount()
{
	return pagesCount;
}

@Override
public Object instantiateItem(View collection, int position)
{
	TextView tv = getNewView();
	Ponk j = data.get(position);
	tv.setText(j.text);
	tv.setTag(j.id);
	setFontSizeInSP(tv, app.getFontSize());
	tv.setTag(position);
	((ViewPager) collection).addView(tv, 0);

	return tv;
}

private TextView getNewView()
{
	LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
	 TextView tv = (TextView)inflater.inflate(R.layout.Ponk, null);
	return tv;
}

@Override
public void setPrimaryItem(ViewGroup container, int position, Object object)
{
	currentView = (TextView) object;
}

@Override
public void destroyItem(View collection, int position, Object view)
{
	((ViewPager) collection).removeView((TextView) view);
}

@Override
public boolean isViewFromObject(View view, Object object)
{
	return view == (TextView) object;
}

@Override
public Parcelable saveState()
{
	return null;
}
}
