I have been trying to solve this simple problem for two days now without success. I know a similar question have been asked before (like here: How do you get the selected value of a Spinner? ), but I haven't been able to solve this yet.
So, I have created a simple app which contains a spinner and a custom ListView. The spinner (containing values 1,2,3,4,5..) creates more spinners (which contain Player names) to the ListView (eg. choosing 4 creates four spinners). Currently, the program works fine except that I don't know how to get the selected values of the spinners in ListView when clicking a button in Action Bar? I tried to use getItemAtPosition and getSelectedXXX() methods but I always tend to the get values from a single spinner I recently selected.
I am not sure do I have to invoke the methods in the Spinner's setOnItemSelectedListener(), or can I call the values from outside the SpinnerAdapter class.
Here is the custom Spinner class
public class PlayerAdapter extends ArrayAdapter<String> {
public PlayerAdapter(ArrayList<String> mPlayers) {
super(getActivity(), 0, mPlayers);
}
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = getActivity().getLayoutInflater().inflate(
R.layout.list_item_players, null);
}
Spinner mSpinnerPlayer = (Spinner) convertView
.findViewById(R.id.spinner_player);
ArrayAdapter<Player> spinnerAdapterPlayer = new ArrayAdapter<Player>(getActivity(), android.R.layout.simple_spinner_item, mPlayers);
spinnerAdapterPlayer.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinnerPlayer.setAdapter(spinnerAdapterPlayer);
mSpinnerPlayer.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// TODO Auto-generated method stub
//Should I use getItemAtPosition or getSelectedXXX methods here?
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});
return convertView;
}
}
}
Here is the Fragment which inflates the layout creates the first spinner (sorry about the formatting and code style)
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRetainInstance(true);
setHasOptionsMenu(true);
//gets player names from a database, such as "Player 1", "Player 2" etc..
//this is container of the spinners displayed in the listview
mPlayers = PlayerDB
.get(getActivity())
.getPlayers();
}
public View onCreateView(LayoutInflater inflater, ViewGroup parent,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment_menu, parent, false);
listView = (ListView) view.findViewById(R.id.listView1);
mSpinnerNumOfPlayers = (Spinner) view.findViewById(R.id.spinner_numOfPlayers);
ArrayAdapter<CharSequence> spinnerAdapter = ArrayAdapter
.createFromResource(this.getActivity(),
R.array.numberOfPlayers_array,
android.R.layout.simple_spinner_item);
spinnerAdapter
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinnerNumOfPlayers.setAdapter(spinnerAdapter);
mSpinnerNumOfPlayers.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
String position = parent.getItemAtPosition(pos).toString();
mArray = new ArrayList<String>();
posInt = Integer.parseInt(position);
for (int i = 0; i < posInt; i++) {
mArray.add("" + i);
}
PlayerAdapter adapter = new PlayerAdapter(mArray);
listView.setAdapter(adapter);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
listView.setOnItemClickListener(new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
}
}
);
return view;
}
// ActionBar
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.main, menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_item_start:
//when "start" button is clicked the spinner values are saved into an ArrayList
