How to add subitems in a ListView
<p>I'm trying to add subItems in my ListView.
My listView should be organized with emails for items and their institution for  the subitems, but with the following code I just added items, how can I add my subitems on it? I've tried so many things but it doesn't work.</p>

<pre><code>        List&lt;Login&gt; listEmails = JsonUtil.getAllEmails(json);

        ArrayList&lt;String&gt; emails = new ArrayList&lt;String&gt;();

        ArrayList&lt;String&gt; institutions = new ArrayList&lt;String&gt;();

        for (Login loginObj : listEmails) {

            emails.add(loginObj.getEmailAndress());
        }

        for (Login loginObj : listEmails) {

            institutions.add(loginObj.getInstitution());
        }

        ArrayAdapter&lt;String&gt; adapter;

        adapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, emails);

        emailListView.setAdapter(adapter);
</code></pre>
