  1. POAndroid: Changing a preference via dialog does not update the value
    text
    copied!<p>I'm using a PreferenceActivity in my app. Defined the settings.xml as follows -</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="Preferences" &gt; &lt;PreferenceCategory android:title="Email Options" &gt; &lt;EditTextPreference android:dialogTitle="@string/pref_email_user_title" android:key="pref_email_user" android:summary="@string/pref_email_user_summary" android:persistent="true" android:title="@string/pref_email_user_title" /&gt; &lt;EditTextPreference android:dialogTitle="@string/pref_email_password_title" android:key="pref_email_password" android:summary="@string/pref_email_password_summary" android:persistent="true" android:title="@string/pref_email_password_title" /&gt; &lt;/PreferenceCategory&gt; </code></pre> <p></p> <p>Activity as follows -</p> <pre><code>public class Prefs extends PreferenceActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.settings); } } </code></pre> <p>Which is all you need, right? Apparently not though, because what happens is that I click on the 'email user' setting, it brings up a dialog which I use to type in a string value. However what I typed in isn't getting placed on the Settings screen, I still see the default value.</p> <p>I notice that the values are getting persisted in the preferences file under <code>/data/data/&lt;package&gt;/shared_prefs</code></p> <p>I also don't see these persisted values when I relaunch the app - it shows default values. What's the bit of magic I'm missing?</p>
