Android ListView: how to select an item?
- by mmo
I am having trouble with a ListView I created: I want an item to get selected when I click on it.
My code for this looks like:
protected void onResume() {
...
ListView lv = getListView();
lv.setOnItemSelectedListener(new OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> adapterView, View view, int pos, long id) {
Log.v(TAG, "onItemSelected(..., " + pos + ",...) => selected: " + getSelectedItemPosition());
}
public void onNothingSelected(AdapterView<?> adapterView) {
Log.v(TAG, "onNothingSelected(...) => selected: " + getSelectedItemPosition());
}
});
lv.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> adapterView, View view, int pos, long id) {
lv.setSelection(pos);
Log.v(TAG, "onItemClick(..., " + pos + ",...) => selected: " + getSelectedItemPosition());
}
});
...
}
When I run this and click e.g. on the second item (i.e. pos=1) I get:
04-03 23:08:36.994: V/DisplayLists(663): onItemClick(..., 1,...) => selected: -1
i.e. even though the OnItemClickListener is called with the proper argument and calls a setSelection(1), there is no item selected (and hence also OnItemSelectedListener.onItemSelected(...) is never called) and getSelectedItemPosition() still yields -1 after the setSelection(1)-call.
What am I missing?

PS.: My list does have =2 elements...
