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

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

And here is an xml for ViewPager

1<?xml version="1.0" encoding="utf-8"?>
2<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
3 android:id="@+id/RelativeLayout1"
4 android:layout_width="fill_parent"
5 android:layout_height="fill_parent"
6 android:orientation="vertical" >
7
8 <android.support.v4.view.ViewPager
9 android:id="@+id/vpPonkSwiper"
10 android:layout_width="fill_parent"
11 android:layout_height="fill_parent"
12 android:layout_above="@+id/lbPonkFooter" />
13
14 <TextView
15 android:id="@+id/lbPonkFooter"
16 android:layout_width="fill_parent"
17 android:layout_height="30dp"
18 android:layout_alignParentBottom="true"
19 android:layout_alignParentLeft="true"
20 android:text="Footer" />
21
22</RelativeLayout>

Here is an Adapter:

1public class PonkPageAdapter extends PagerAdapter
2{
3 private int pagesCount = -1;
4 private List<Ponk> data;
5 private App app;
6 private MockPersistence db;
7 private Activity activity;
8 private TextView currentView;
9 private LayoutInflater inflater;
10
11 public PonkPageAdapter(Activity activity, byte section) {
12 this.activity = activity;
13 this.app = ((App) activity.getApplication());
14 this.db = app.getPersistence();
15 this.section = section;
16 this.data = db.findPonksBySection(section); // new LinkedList<Ponk>();
17 this.inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
18 //
19 this.pagesCount = db.countPonksInSection(section);
20 }
21
22 @Override
23 public int getCount()
24 {
25 return pagesCount;
26 }
27
28 @Override
29 public Object instantiateItem(View collection, int position)
30 {
31 TextView tv = getNewView();
32 Ponk j = data.get(position);
33 tv.setText(j.text);
34 tv.setTag(j.id);
35 setFontSizeInSP(tv, app.getFontSize());
36 tv.setTag(position);
37 ((ViewPager) collection).addView(tv, 0);
38
39 return tv;
40 }
41
42 private TextView getNewView()
43 {
44 LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
45 TextView tv = (TextView)inflater.inflate(R.layout.Ponk, null);
46 return tv;
47 }
48
49 @Override
50 public void setPrimaryItem(ViewGroup container, int position, Object object)
51 {
52 currentView = (TextView) object;
53 }
54
55 @Override
56 public void destroyItem(View collection, int position, Object view)
57 {
58 ((ViewPager) collection).removeView((TextView) view);
59 }
60
61 @Override
62 public boolean isViewFromObject(View view, Object object)
63 {
64 return view == (TextView) object;
65 }
66
67 @Override
68 public Parcelable saveState()
69 {
70 return null;
71 }
72}
