Android SqList mid-range subscript cross-over problem solution

The following error occurred while using Android SqList

Android.database.CursorIndexOutOfBoundsException:Index requested, with a size of 14

After elimination, the wrong position is determined.

The error code is

Public arraylist<receivecontext> query (String table_name,string[] arg) { Sqlitedatabase db=getwritabledatabase (); Cursor c = db.query (table_name,null,poster+ "=?", arg,null,null,updatetime,null);// Query and get cursor arraylist<receivecontext> l=new arraylist<receivecontext> (); if (C.moveToFirst ()) {/ /Determine if the cursor is empty     for (Int i=0;i<c.getcount (); i++) {         c.movetoposition (i);//correct statement         //c.move (i);   Error Statement                 string  getcontext= "";        int getstyle = 0;         string gettime= "";                 getcontext= c.getstring (C.getColumnIndex (context)); &nBsp;       getstyle =c.getint (C.getcolumnindex (style));         gettime = c.getstring (C.getcolumnindex (updateTime));         receivecontext rc=new receivecontext (getContext,getStyle,getTime );         l.add (RC);     }}c.close ();d b.close (); Return l;}

This is the way I write a database query, the reason for the cross-border is the use of method C.move (i); This method I estimate (to be verified) should be the current pointer +i, so it will cause a cross-border. The right approach should be

C.movetoposition (i);

This is the jump to the first position.
