I am creating a android app the UI of my application is below given.
On clicking of submit button, I need the selected check box, and radio buttons value.
Example Linux is not checked, cc(radio button) is checked.
Records are populated dynamically in list view, but I am not able to make it work. A lot of problems are there.
- When I scroll the list view radio button gets automatically selected or deselected not able to maintain the state of radio button.
- On click of button not getting the selected radio button as well as check box.
Below is my layout as well as java program. Suggest me to get the correct values.
