android - Issue with custom SimpleCursorAdapter -

i'm trying fill grid view using info db cursor using custom simplecursoradapter. cursor has info (i checked), nil shown in gridview, , getview() method not called.

anybody can help? why getview() not called?

thanks

activity

dbadapter = new dbadapter(this); dbadapter.open(); cursor c; c = dbadapter.fetchpclist(); startmanagingcursor(c); string[] = new string[] {}; int[] = new int[] {}; gridview gridview = (gridview) findviewbyid(r.id.gridview); gridview.setadapter(new pciconadapter(this, r.layout.pc_icon, c, from, to)); c.close(); dbadapter.close();

adapter

public class pciconadapter extends simplecursoradapter { private final context mcontext; private final int mlayout; private final cursor mcursor; private final int mpcidindex; private final int mclassnameindex; private final layoutinflater mlayoutinflater; private final class viewholder { public textview pc_id_view; public textview clas_name_view; } public pciconadapter(context context, int layout, cursor c, string[] from, int[] to) { super(context, layout, c, from, to); this.mcontext = context; this.mlayout = layout; this.mcursor = c; this.mpcidindex = mcursor.getcolumnindex(dbadapter.key_pc_lm_id); this.mclassnameindex = mcursor.getcolumnindex(dbadapter.key_pc_clas_name); this.mlayoutinflater = layoutinflater.from(mcontext); } public view getview(int position, view convertview, viewgroup parent) { if (mcursor.movetoposition(position)) { viewholder viewholder; if (convertview == null) { convertview = mlayoutinflater.inflate(mlayout, null); viewholder = new viewholder(); viewholder.pc_id_view = (textview) convertview.findviewbyid(r.id.pc_id); viewholder.clas_name_view = (textview) convertview.findviewbyid(r.id.clas_name); convertview.settag(viewholder); } else { viewholder = (viewholder) convertview.gettag(); } string pc_id = mcursor.getstring(mpcidindex); string clas_name = mcursor.getstring(mclassnameindex); viewholder.pc_id_view.settext(pc_id); viewholder.clas_name_view.settext(clas_name); } homecoming convertview; } }

i had same problem. using arrayadapter , changed simplecursoradapter, doesn't show on screen.

i removed

c.close(); dbadapter.close();

and working fine.

android gridview simplecursoradapter

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
