To hide an arbitrary item or more than one item I think that you can implement your own adapter and set the index (or array list of indexes) that you want to hide.
public class CustomAdapter extends ArrayAdapter<String> {
private int hidingItemIndex;
public CustomAdapter(Context context, int textViewResourceId, String[] objects, int hidingItemIndex) {
super(context, textViewResourceId, objects);
this.hidingItemIndex = hidingItemIndex;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
View v = null;
if (position == hidingItemIndex) {
TextView tv = new TextView(getContext());
tv.setVisibility(View.GONE);
v = tv;
} else {
v = super.getDropDownView(position, null, parent);
}
return v;
}
}
And use your custom adapter when you create the list of items.
List<String> list = new ArrayList<String>();
list.add(""); // Initial dummy entry
list.add("string1");
list.add("string2");
list.add("string3");
int hidingItemIndex = 0;
CustomAdapter dataAdapter = new CustomAdapter(this, android.R.layout.simple_spinner_item, list, hidingItemIndex);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mySpinner.setAdapter(dataAdapter);
(I have not tested the code) hope that helps.
