If we look at the following code, we have name and value array in getView and getDropDownView.
private void initView() {
SpinnerDropDownAdapter sddadapter = new SpinnerDropDownAdapter(this);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, sddadapter.name);
Spinner getViewSP = (Spinner) findViewById(R.id.getview_sp);
getViewSP.setAdapter(adapter);
Spinner getViewWDropDownSP = (Spinner) findViewById(R.id.getview_w_drop_down_sp);
getViewWDropDownSP.setAdapter(sddadapter);
}
static class SpinnerDropDownAdapter extends BaseAdapter implements
SpinnerAdapter {
Context context;
SpinnerDropDownAdapter(Context ctx) {
context = ctx;
}
String[] name = { " One", " Two", " Three", " Four", " Five", " Six",
" Seven", " Eight" };
String[] value = { " 1", " 2", " 3", " 4", " 5", " 6", " 7", " 8" };
@Override
public int getCount() {
return name.length;
}
@Override
public String getItem(int pos) {
// TODO Auto-generated method stub
return name[pos];
}
@Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView text = new TextView(context);
text.setTextColor(Color.BLACK);
text.setText(name[position]);
return text;
}
@Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
TextView text = new TextView(context);
text.setTextColor(Color.BLACK);
text.setText(value[position]);
return text;
}
}
If getDropDownView method is not implemented, the drop down pop up will get the view from getView. Thus, it will only show name.
When both getView and getDropDownView is implemented, the former getting name and the latter getting value, the spinner at rest will get name from getview and the drop down pop up will get value.
