copied!<p>As others have already pointed out your, expectations of simply using <code>Arrays.asList()</code> and casting to your data list is incorrect and will not work. As you use <code>SharedPreferences.Editor.putString()</code> you'll insert a <code>String</code> in the preferences representing the string returned by <code>List.toString()</code>(which will print all of its children(using <code>toString()</code>) in square brackets). When you get this string from the preferences back, you need to build it up into a <code>List</code> of <code>NewsItems</code>. One way of how you can do this would be like below:</p> <pre><code>for (Entry<String, ?> entry : pref.getAll().entrySet()) { List<NewsItem> rowItems = new ArrayList<NewsItem>(); // the string from the preferences as it was saved String prefContent = (String) entry.getValue(); // break against possible multiple NewsItems(I'm assuming that's // why you use a List of NewsItems) for the same // key (every NewsItem starts with * so we split after // that(see the NewsItems.toString method)) String[] newsItems = prefContent.split("\\*"); for (String item : newsItems) { // an item which doesn't have at least 50 characters // isn't a valid NewsItem string representation(based on // its toString() method) if (item.length() > 50) { // ; is the delimiter for the NewsItem's data String[] components = item.split(";"); NewsItem ni = new NewsItem(); // for each of the four data components we split // after = and then use the second value obtained as // that will be the value for that component ni.setHeadline((components[0].split("="))[1]); ni.setSpeed((components[1].split("="))[1]); ni.setDirection((components[2].split("="))[1]); ni.setDate((components[3].split("="))[1]); rowItems.add(ni); } } listDataChild.put(entry.getKey(), rowItems); } </code></pre> <p>The code above would require a change in the <code>toString()</code> method of the <code>NewsItem</code> class:</p> <pre><code>@Override public String toString() { StringBuilder sb = new StringBuilder(); sb.append("*headline="); sb.append(headline); sb.append(";"); sb.append("speed="); sb.append(speed); sb.append(";"); sb.append("direction="); sb.append(direction); sb.append(";"); sb.append("date="); sb.append(date); return sb.toString(); } </code></pre>
