Android:To set an item as selected when the ListView opens?

Question

An activity has a Button and a ListView. Initially, only the Button is visible. When the button is pressed, the ListView is displayed. When displayed, is it possible for me to show one particular item as selected/focussed?

A use case could be that suppose it is a list of language settings and when the list opens, the currently selected language must be shown as highlighted.

If I know the index of the item, how to set it as focused on display?

Answer 1

I post my solution, because google still doesn't know the answer.

getListView().setItemChecked(selectedGroupIndex, true);

Answer 2

In short, ListView::setSelection(int position) is what you need. However, depending on whether the device is in touch mode or not, it may or may not have visual effect (background highlighting). For more details, refer to Android ListView Selection Problem
