How to Keep the state of an XML View on orientation change Android

I've got the following issue I'm implementing an app that provides different types of surveys that has different types of supported questions/answers

  • RadioButtons
  • Check Boxes
  • Text Fields
  • Image select
  • drag & drop items

what I want is when I change the orientation of the device, I keep the same state

i.e --> the text would still be inside the text field ... keep the user's selections on the Radio Group / Check Boxes... etc

I've already tried to override

onsaveInstance & onRestoreInstance

but the problem is I have different types of views & the answer can be viewed as any of them depending on the question type

so I was thinking of saving the whole XML View & then pass it again to the setContentView()

any help?

Solution

  • Use android:configChanges="keyboardHidden|orientation" in Activity in android manifest file.

    Example

     <activity
     android:name=".ui.Contact"  android:configChanges="keyboardHidden|orientation"/>

    It is Keep the state of an XML View on orientation change .
