POSwipe / (Fling) with dynamic views

Body
copied!<p><strong>What i want to:</strong></p> <p>I want to add a swipe or what i learned it's named on android fling, to my app. I have a dynamic number of views, the number is the amount of dates from an ICS file which i parse, i want to make a swipe effekt on all of these views together. But if i have let's say 12 of these each having a ListView with 8 items (max) it would use a lot of memory i guess. So i would like that only the 2 before current selected view and the 2 after to be initialized.</p> <p><strong>What i have tried:</strong></p> <p>In my search i stumpled around <a href="https://stackoverflow.com/questions/5071743/how-to-make-an-android-view-that-flips-between-views-on-swipe-fling">this stackoverflow question</a> which mentions HorizontalPager. But i dont know to make it work with a number of ListView's and load them dynamically.</p> <p>I tried a ViewGroup and then add and remove a ListView but it's not working, it display's the ViewGroup but not the ListView</p> <pre><code>public class HourView extends ViewGroup { private ListView listView; /** * @param context */ public HourView(Context context) { super(context); init(false); } /** * * @param context * @param day the current day */ public HourView(Context context, String day, boolean shouldBeVisible) { super(context); this.day = day; init(shouldBeVisible); } private void init(boolean shouldBeVisible) { if (shouldBeVisible) { listView = new ListView(getContext()); if (day == null) { day = Event.dtFormatDay.format(new Date()); } new GetEvents(day).execute(); addView(listView); } else { removeAllViews(); listView = null; } } } </code></pre> <p>The GetEvents() is a AsyncTask (a class inside the viewgroup class) that gets some events from a local database, the code is the onPostExecute is as follows</p> <pre><code>protected void onPostExecute(String errMsg) { if (errMsg != null) { listView.setAdapter(new SkemaHoursRowAdapter(getContext(), eventItems)); listView.requestLayout(); addView(listView, layoutParams); } } </code></pre> <p>eventItems is an array i parse to my custom rowadapter (which i know works). The view group is displayed but the listView is not. </p> <p>Any suggestions??</p>
