Question

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?

Answer 1

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 .
