    copied!<p>I'm trying to create a preferences screen with a dynamic list of entries, and when clicking each of them, I have another screen of preferences. As an example, think of a list of mail accounts and each one having their account settings available.</p> <p>While I can create the nesting I want using just <code>PreferenceScreens</code>, this can't easily be scaled to multiple entries without creating the sub preferences structure in code for each one.</p> <p>I see several different variations throughout the Android UI.</p> <p>Is there a recomended way to create such a structure as this?</p> <p>Possibilites include:</p> <ol> <li><p>Separate, independant activities<br> Works but is messy in my opinion</p></li> <li><p>Nested, code created PreferenceScreens<br> Pain in the ass for maintainence and it means the preferences are no longer stored as XML fragments</p></li> <li><p>Nested, inflated PreferenceScreens<br> I can't find a way to expand another XML file into a sub tree</p></li> <li><p>One "sub" PreferenceScreen that is shown using setPreferenceScreen() for each one<br> I can't find a way to hide the "template" PreferenceScreen and it breaks the navigation.</p></li> </ol> <p>Sample XML:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" android:title="@string/prefs_title"&gt; &lt;EditTextPreference android:key="add_console" android:title="@string/prefs_add_console"&gt;&lt;/EditTextPreference&gt; &lt;PreferenceCategory android:title="@string/prefs_consoles_title" android:key="list"&gt; &lt;PreferenceScreen android:summary="http://cctv.icode.co.uk/" android:title="iCode Console"&gt; &lt;/PreferenceScreen&gt; &lt;PreferenceScreen android:summary="http://test.icode.co.uk/" android:title="Test Console"&gt; &lt;/PreferenceScreen&gt; &lt;/PreferenceCategory&gt; &lt;PreferenceScreen android:title="Console (template)" android:key="console"&gt; &lt;EditTextPreference android:title="@string/prefs_console_host" android:summary="@string/prefs_not_set" android:key="host"&gt;&lt;/EditTextPreference&gt; &lt;CheckBoxPreference android:title="@string/prefs_console_auth" android:summary="@string/prefs_console_auth_summary" android:key="auth"&gt;&lt;/CheckBoxPreference&gt; &lt;EditTextPreference android:shouldDisableView="true" android:title="@string/prefs_console_authuser" android:key="authuser" android:dependency="auth" android:summary="@string/prefs_not_set"&gt;&lt;/EditTextPreference&gt; &lt;EditTextPreference android:title="@string/prefs_console_authpass" android:key="authpass" android:dependency="auth" android:summary="@string/prefs_not_set"&gt;&lt;/EditTextPreference&gt; &lt;CheckBoxPreference android:title="@string/prefs_console_pair" android:summary="@string/prefs_console_pair_summary" android:key="pair"&gt;&lt;/CheckBoxPreference&gt; &lt;/PreferenceScreen&gt; &lt;/PreferenceScreen&gt; </code></pre> <p>I want the entries under <code>list</code> to be dynamic and show the <code>console</code> preferences under each.</p> <p>All other ideas welcome.</p> <p>Thanks </p>
