I write app that include Gridview ,for display products,thus when select item in grid, return value is nullpointerException.when i use listview its okay but in Gridview its error.
grid_data.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
title = ((TextView) view.findViewById(R.id.title)).getText()
.toString();
categoriid = ((TextView) view.findViewById(R.id.categoryid))
.getText().toString();
String productid = ((TextView) view
.findViewById(R.id.productid)).getText().toString();
}
});
adapter class :
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (vi == null)
//LayoutInflater inflater = ((Activity) activity).getLayoutInflater();
vi = inflater.inflate(R.layout.full_image, parent, false);
TextView title = (TextView) vi.findViewById(R.id.txt_title); // title
TextView maxprice = (TextView) vi.findViewById(R.id.txt_maxprice); // artist
TextView minprice = (TextView) vi.findViewById(R.id.txt_minprice); // artist
TextView productid = (TextView) vi.findViewById(R.id.productid); // artist
TextView categoryid = (TextView) vi.findViewById(R.id.categoryid); // artist
ImageView thumb_image = (ImageView) vi
.findViewById(R.id.full_image_view); // thumb
// image
HashMap<String, String> song = new HashMap<String, String>();
song = data.get(position);
title.setText(song.get(Service.Key_Title));
productid.setText(song.get("Productid"));
categoryid.setText(song.get("Categoryid"));
maxprice.setText(song.get("MaxPrice"));
minprice.setText(song.get("MinPrice"));
imageLoader.DisplayImage(song.get("picPath"), thumb_image);
return vi;
