public class listadapter extends baseadapter { private static layoutinflater inflater=null; private activity activity; private arraylist<string> imagedata; public listadapter(activity a, arraylist<string> list) { activity = a; imagedata = list; inflater = (layoutinflater)activity.getsystemservice(context.layout_inflater_service); } @override public int getcount() { // todo auto-generated method stub return imagedata.size(); } @override public object getitem(int position) { // todo auto-generated method stub return position; } @override public long getitemid(int position) { // todo auto-generated method stub return position; } @override public view getview(int position, view convertview, viewgroup parent) { view vi = convertview; if(convertview==null) vi = inflater.inflate(r.layout.list_row, null); imageview thumb_image=(imageview)vi.findviewbyid(r.id.imagethumb); // thumb image textview text=(textview)vi.findviewbyid(r.id.listtext); bitmap mybitmap = bitmapfactory.decodefile(imagedata.get(position)); thumb_image.setimagebitmap(mybitmap); text.settext(position); return vi; } } when comes mainactivity, don't see images in listview. please me out. doing wrong?
edit
"multiphotoselectactivity.java - returns path of images selected

you haven't attached multiphotoselectactivity class code, isn't clear result after clicking gallery button. anyway, should use cursorloader query mediastore images instead. , why decoding bitmaps , not use uil (like mentioned) or picasso?
