I am building an App with the new Navigation Drawer. Therefore i created several fragments, which are my app pages. One App page has a preference layout (extending preferencefragments). I have a listpreference loaded with dynamic values. I have setup another preference screen after this list. Now what i want to do is, create depending on what the user selected from the list a dynamic generated preference layout with EditTextPreference.
I can't do this statically in xml, because i can't control how many EditTextPreference items are needed before the app compiles. Is there any way how i can set up a dynamic loadable preferences? Maybe completely without xml only in java? Does android support a layout completely written in java at all? I don't need to take care where this will be saved. It should be loaded dynamically too.
Like (Pseudo-Code);
if (list.item3 == selected)
show edittext1
show edittext2
if (list.item1 == selected)
show edittext8
show edittext4
show edittext9
See screenshot for a better explanation.
Any help here is much appreciated!

This is indeed possible and I do it on my app. In Java you need to make a custom class that extends EditTextPreference. Then override the methods you want to change. You can then add your custom view right into your xml like you would a normal EditTextPreference, except when you would create an xml element with the name of EditTextPreference you would do the full package name of your custom preference.
eg:
<com.your.name.CustomPreference
<!-- add all the andoid:x attributes you normaly would:-->
android:defaultValue="default string"
etc,
....
