My user settings fragment does not work
It´s really simple - thus it should work.
Menu user settings -> onOptionsItemSelected-> new Intent -> startActivityForResult(intent, key) -> now it should use the fragment.xml.
UserPreferencesFragment.java
public class UserPreferencesFragment extends PreferenceFragment {
private static String SETTINGS_NAME_KEY = "name";
private static String SETTINGS_EMAIL_KEY = "name";
public static String getName(Context context) {
return PreferenceManager.getDefaultSharedPreferences(context).getString(SETTINGS_NAME_KEY, "");
}
public static String getEmail(Context context) {
return PreferenceManager.getDefaultSharedPreferences(context).getString(SETTINGS_EMAIL_KEY, "");
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//adding the preferences from the xml
//so this will in fact be the whole view.
addPreferencesFromResource(R.xml.prefs);
}
}
XML file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView

Now all should be well, but I get a massive exception which is posted in its whole.

The root layout of your prefs.xml file must be <PreferenceScreen> not <LinearLayout>, you're using wrong file i guess
