The same way works in FireMonkey as in VCL code - use the TComboBox.Items
. TComboBox.ItemIndex
tells you which one is currently selected (or allows you to set the selection).
To read:
if ComboBox1.ItemIndex <> -1 then
ShowMessage(ComboBox1.Items[ComboBox1.ItemIndex]);
To set:
ComboBox1.ItemIndex := 2;
