[bala venkata siva ram kum]

hi

I want autocompletetextview in android here we are using sqlite database with query using cursor.

public void cal()
{
    SQLiteDatabase db= null;
    String TableName = "enquiryhead";
    db = openOrCreateDatabase("DatabaseName", SQLiteDatabase.CREATE_IF_NECESSARY, null);
    db.setVersion(1);
    db.setLocale(Locale.getDefault());
    db.setLockingEnabled(true);
    Cursor c = db.rawQuery("SELECT splr_nm FROM " + TableName , null);
    int Column1=c.getColumnIndex("splr_nm");
//Check if our result was valid.
    //Data=Data+"OrderNo  | Date  |  SuppierName"+"\n";
    int k=0;
    c.moveToFirst(); 
    if (c != null)
    { 
     // Loop through all Results
        item = new String[Column1];
     do { 
         String sname=c.getString(Column1);
           item[k]=sname;
          k++;                
            }while(c.moveToNext());
    }
 

The above code is retrieve data from data base and assign to item, i.e item is string, but its not working
