Android Save instance state for dialogs?

I wonder how to implement this correctly? Can someone find out if my decision is right?

So:

  • Action created
  • The user presses the button and the dialogue starts (dialogue, not dialogue style)
  • The user opens the keyboard.
  • We have onSaveInstanceState, where we save that our dialog has been opened, and all relevant dialog entries
  • we have onRestoreInstanceState, and here we check if the dialog was shown, re-create the dialog with the appropriate input.

Is this the right approach? or is smth. what Android does and I do some redundant actions.

thanks

Yes, this is the right way to do this. Dialog does not extend Activity s, but they work very similarly, and you just described the correct "stream" for saving / restoring states for.

Try commenting on your onRestoreInstanceState () and see if the application loads the information you expected to save.

I hope this helps! Greetings.
