Options Menu on Spinner
I'm looking for a way to add items to a spinner from within the spinner item list dialog.
Ideally, I could hit the menu button and select an option to add, prompt the user with an edittext dialog and update the item list. Is there a way to make the options menu accessible on a dialog?
I thought I might need to create an activity b开发者_运维知识库ut then how do I make it look like a spinner item list dialog and how would I get it to show up when the spinner is clicked?
All I'm trying to do is add an unobtrusive way to launch a prompt to add items to the spinner item list from within the dialog. Any ideas?
How about allowing them to long-click the list and handling the long click event?
Spinner s=(Spinner) findViewById(R.id.yourspinner);
s.setOnLongClickListener(new OnLongClickListener(){}...
public class Main extends Activity {
/** Called when the activity is first created. */
private ArrayList<String> array_spinner;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Spinner s = (Spinner) findViewById(R.id.Spinner01);
array_spinner=new ArrayList<String>();
array_spinner.add("value");
array_spinner.add("value 2");
ArrayAdapter adapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_item, array_spinner);
adapter.setNotifyOnChange(true);
s.setAdapter(adapter);
s.setLongClickable(true);
s.setOnLongClickListener(new OnLongClickListener(){
@Override
public boolean onLongClick(View v) {
// TODO Auto-generated method stub
array_spinner.add("value 3");
return false;
}}
);
}
}
