android - Dynamically added EditText is not visible when created -
i have been reading how dynamically add edittext field linear layout, every-time user clicks textview (which has onclick listener attached).
i have had mild success - know edittext field being created because when button clicked, other elements move if being added screen.
my problem edittext aren't visible , haven't clue why is, appreciated.
the app isn't crashing nothing add in terms of stacktrace , log, far app concerned, being created.
