Retourneer de gezochte gegevens van sqlite

In uw zoekopdracht item is string, dus verander

String strquery="select * from Articles where AS_name= "+item;

naar

String strquery="select * from Articles where AS_name='" + item + "'";

Of deze

Cursor cur=null;
cur = db.query("Articles", null, "AS_name" + "=?",
            new String[] { item }, null, null, null, null);

in plaats van

Cursor cur=null;
String strquery="select * from Articles where AS_name= "+item;
cur=db.rawQuery(strquery,null); 

En verander

strvalue=cur.getString(0);

naar

strvalue=cur.getString(cur.getColumnIndex("Desc_art"));
