Hi !
I had made an application which download a huge list from the internet and
display in a listview. The Listview class is supported by my own Class which
is extension of the BaseAdapter base class. In the display list adapter
getView method I use simple_list_item_multiple_choice.
When I would like to insert an progressdialog with a Thread, the System is
die with NullPointer Exception in the last row:
*public View getView(int position, View convertView, ViewGroup parent) {
if(convertView == null)
{
convertView =
inflater.inflate(android.R.layout.simple_list_item_multiple_choice,
parent,false);
}
try {
ViewHolder vh = new ViewHolder();
vh.checkTextView = (CheckedTextView)
convertView.findViewById(android.R.id.text1);
vh.checkTextView.setEnabled(true);
*
BUT if I don't use the Thread all going to right, there will no NullPointer
Exception
Can anyone tell me why ? Any solution ?
