I have been using values of spinner from XML string-arrays so far like:
Spinner karant_sp;
karant_sp = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> karant_adapter = ArrayAdapter.createFromResource(this, R.array.karant_list, android.R.layout.simple_spinner_item);
karant_adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
karant_sp.setAdapter(karant_adapter);
karant_sp.setSelection(0);
karant_sp.setOnItemSelectedListener(new select_karant());
Can I use a local java ArrayList-String as the list of items to be displayed in drop down menu?
Something like:
Spinner karant_sp;
ArrayList<String> return_likes = new ArrayList<String>();
return_likes.add("Hello");
return_likes.add("world");
karant_sp = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> karant_adapter = ArrayAdapter.createFromResource(this, return_likes, android.R.layout.simple_spinner_item);
karant_adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
karant_sp.setAdapter(karant_adapter);
karant_sp.setSelection(0);
karant_sp.setOnItemSelectedListener(new select_karant());
I know the above code doesn't work, but I would like to know something which works using ArrayList-string.
Yes. Just don't call
createFromResource()
on yourAdapter
. Use one of the constructors instead. Something likeThis is just an example you might have to change something else to get it working depending on what isn't working. But The ArrayAdapter Docs should help.
