E in GetView sto usando qualcosa di simile:Visualizzazione di stato per l'ultimo elemento della lista in una lista utilizzando ViewHolder
public View getView(final int position, View convertView, ViewGroup parent) {
holder.dataImageView.setImageResource(R.drawable.bullet_button);
try {
// check data exist or not
boolean strDataExistU = myDbbv.Exists(fileNameDB);
if(strDataExistU)
{
holder.dataImageView.setImageResource(R.drawable.online);
}
else
{
boolean strDataExist = myDb.Exists(fileNameDB);
if(strDataExist)
{
holder.dataImageView.setImageResource(R.drawable.local);
}
else
{
holder.dataImageView.setImageResource(R.drawable.default);
}
}
} catch (Exception e) {
}
}
Come si può vedere in GetView (...) metodo, io sono utilizzando tre diversi tipi di drawable (vale a dire: - online, locale, predefinito)
Dove online mostra i dati sono stati caricati sul server online, locale mostra che questo è stato aggiunto al database locale e predefinito .. (né caricato sul server né memorizzato nel database locale)
Problema:
Ogni volta che sto facendo caricamento collettivo, ottenendo drawable online solo per l'ultimo elemento riga di una lista, mentre ho caricato i dati interi di voci di elenco di server di
voglio solo mostrare drawable online tutti gli elementi della lista, quelli che ho caricato sul server, altrimenti il mio codice funziona bene ...

Sono confuso dopo aver letto la tua domanda. –
in 'onPostExecute' si supponga di usare' dataPosition' invece di 'globalPosition' – Bharatesh
ho provato anche con dataPosition, ma ottengo lo stesso risultato – Sun
