<p>For example: I have 2 pages in PageAdapter. When I go to second page, I click on button "Lock" and horizontal scrolling is off. I click "Unlock" and again can scrolling. How block scrolling ? Code:</p> <pre><code>public class slide extends PagerAdapter { List<View> pages = null; // empty list views public slide (List<View> page) { this.pages = page; } @Override public int getCount() { return pages.size(); } @Override public boolean isViewFromObject(View view, Object obj) { return view.equals(obj); } @Override public Object instantiateItem (View views, int position) { View v = pages.get(position); ((ViewPager) views).addView(v, 0); return v; } @Override public void destroyItem(View views, int position, Object view) { ((ViewPager) views).removeView((View) view); } @Override public void finishUpdate(View view) { } @Override public void restoreState(Parcelable arg0, ClassLoader arg1) { } @Override public Parcelable saveState() { return null; } @Override public void startUpdate(View view) { } </code></pre> <p>In Activity:</p> <pre><code> List<View> pages = new ArrayList<View>(); View page = inflater.inflate(R.layout.page, null); TextView textView = (TextView) page.findViewById(R.id.text_view); textView.setText("Page 1"); // first page pages.add(page); page = new surfaceControl(this); // second page with some modul pages.add(page); slide pageAdapter = new slide(pages); ViewPager viewPager = new ViewPager(this); viewPager.setAdapter(pageAdapter); viewPager.setCurrentItem(0); </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
