Override getDropDownView method in ArrayAdapter and put setSingleLine(false) in post method of view. So when view completly created it wraps the text to appropriate lines.
@Override
public View getDropDownView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = new TextView(_context);
}
TextView item = (TextView) convertView;
item.setText("asddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd");
final TextView finalItem = item;
item.post(new Runnable() {
@Override
public void run() {
finalItem.setSingleLine(false);
}
});
return item;
}
