android - Change layout dynamically in DialogFragment -


i want use dialog allow user scan device files extension , import of them.

to that, plan show dialog, have following behaviour:

  1. while scan sd card, dialog show progress bar , 1 textview path of last file found.
  2. after scanning sd card, show list in same dialog files found. user select of them (with checkboxes) , click on "import" or "cancel".

i'm wondering what's best strategy implement this?

i can think of 2 possibilites:

  • use 2 fragments (one each 1 of steps explained above), , switch fragment when scan finishes. far couldn'αΊ— find how switch fragment inside dialog.
  • use 1 fragment , change layout dinamically. means having single layout both functionalities, , show or hide them alternatively (with view.visible , view.gone). prefer other option because here inflate view won't shown.

display listview dialogfragment , use emtptyview progress. implement loader scan files. when loader finished work use adapter listview , empty view disapear automaticly.
