    Default I having problems adding the value into the list as viewlist after input name and submit ok

    Hi guys, i'm currently developing an counter app however i was having trouble Working with ListView in Android. Customize ListView, Add item via a Button Click. And also clickable each button in each row. here is my code note spinner 1 (sub view1) is works only for testing purpose spinner 2 (subview2) is where i'm having trouble adding the value into the list with a counter while creating. after that it then allows browsing of a list to retrieve and earlier count and optionally continue that count and prompts for count name on start of a new tally.

    Default I having problems adding the value into the list as viewlist after input name and submit ok

    Hi guys, i'm currently developing an counter app however i was having trouble Working with ListView in Android. Customize ListView, Add item via a Button Click. And also clickable each button in each row. here is my code note spinner 1 (sub view1) is works only for testing purpose spinner 2 (subview2) is where i'm having trouble adding the value into the list with a counter while creating. after that it then allows browsing of a list to retrieve and earlier count and optionally continue that count and prompts for count name on start of a new tally.

    HTML Code:
