    <p>I am using a custom filter for a search function on my list of user installed applications. It works great but the search only works for search the application package names. In other words, it only searches the package name and not the actual application name. For example, to search for gmail, if I type in "gmail", I get no results, whereas if I search "gm" I get gmail in the results because it is a part of gmail's package name. </p> <p>I want to search both the package name AND application name though, so how could I do this? Here is my coding:</p> <pre><code> @Override public Filter getFilter() { if(filter == null) { filter = new Filter() { @Override protected FilterResults performFiltering(CharSequence constraint) { FilterResults results = new FilterResults(); List&lt;ApplicationInfo&gt; myFilteredAppList = new ArrayList&lt;ApplicationInfo&gt;(); constraint = constraint.toString().toLowerCase(); if (constraint.length() == 0) { myFilteredAppList.addAll(originalListAppInfo); } for (ApplicationInfo appInfo : originalListAppInfo) { String somefield = appInfo.packageName; if (somefield.toLowerCase().contains(constraint.toString())) { myFilteredAppList.add(appInfo); } } results.count = myFilteredAppList.size(); results.values = myFilteredAppList; return results; } @Override protected void publishResults(CharSequence constraint, FilterResults results) { if(results.values != null) { mListAppInfo = (List&lt;ApplicationInfo&gt;)results.values; notifyDataSetChanged(); } } }; } return filter; } </code></pre> <p>I filter the search in this line:</p> <pre><code>String somefield = appInfo.packageName; </code></pre> <p>as you can see it filters just the packageName not the packageName and ApplicationName.</p> <p>ADDED ERROR:</p> <p><img src="https://i.stack.imgur.com/QEJtY.png" alt="enter image description here"></p>

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.
