POHow to force ViewPager to re-instantiate its items
text
Body
copied!<p>I am using <code>ViewPager</code> to allow user to swipe between its views. Is there a way how to force this <code>ViewPager</code> to reload/re-instantiate its views in case that they are no longer valid or needs to be refreshed? I tried to call <code>notifyDataSetChanged()</code> on its adapter but this does not invoke <code>instantiateItem()</code> method again.</p> <h2>EDIT</h2> <p>Here is the class that extends from ViewPager and its adapter definision. Bellow is the <code>refresh()</code> method that I call when I want to force to refresh items. </p> <pre><code>public class DayFlipper extends ViewPager { public class FlipperAdapter extends PagerAdapter { @Override public int getCount() { return DayFlipper.DAY_HISTORY; } @Override public void startUpdate(View container) { } @Override public Object instantiateItem(View container, int position) { Log.d(TAG, "instantiateItem(): " + position); Date d = DateHelper.getBot(); for (int i = 0; i < position; i++) { d = DateHelper.getTomorrow(d); } d = DateHelper.normalize(d); CubbiesView cv = new CubbiesView(mContext); cv.setLifeDate(d); ((ViewPager) container).addView(cv, 0); // add map cv.setCubbieMap(mMap); cv.initEntries(d); return cv; } @Override public void destroyItem(View container, int position, Object object) { ((ViewPager) container).removeView((CubbiesView) object); } @Override public void finishUpdate(View container) { } @Override public boolean isViewFromObject(View view, Object object) { return view == ((CubbiesView) object); } @Override public Parcelable saveState() { return null; } @Override public void restoreState(Parcelable state, ClassLoader loader) { } } ... public void refresh() { getAdapter().notifyDataSetChanged(); } } </code></pre>
