Android Question How to check multiple checkbox at a time without adding tag

RJB said:

If you can use a common _CheckedChange sub then possibly
edit: or you could put the +1 / -1 bit in each _CheckedChange sub

B4X:

Sub CommonCheckbox_CheckedChange(Checked As Boolean)
       if checked then
             BoxChecked = boxchecked + 1
      else
             BoxChecked = boxchecked - 1
      end if
       if boxchecked > 6 then boxchecked = 6 'shouldn't be needed but........
       if boxchecked < 0 then boxhecked = 0   'shouldn't be needed but........
end sub

if boxchecked > 0 then some task 'if at least one is checked
if boxchecked = 6 then some other task 'if all are checked

        If v Is CheckBox Then
            Dim chk As CheckBox = v
            If chk.Checked Then Return True
        End If
    Next

Dear Nitin,

RJB logic is when a check box is clicked, the click event adds 1 in a variable, so check this variable value.

If you always want to have only one CheckBox selected use RadioButtons instead they are designed exactly for that.
You can group RadioButtons on Panels. RadioButtons on different Panels don't interact.

Sub VerifyCheckBox
    For Each v As B4XView In Activity.GetAllViewsRecursive
        If v Is CheckBox Then
            If  v.Checked Then  v.Text = "True" Else v.Text = "False"
        End If
    Next
End Sub
