How to bulk insert or update in sqlite android?

Let me explain my problem precisely i just want to insert 1000's of records in a single shot but it taking some time having some performance issue, is there anyway to improve the performance while doing insert or update operation. Let me explain what i have tried so far :

     public void VisitStatusInsertorUpdate(VisitStatusModel modlobj) {
            String query = " SELECT  * FROM " + VisitStatusModel.table  + " WHERE " + VisitStatusModel.statusid  + "  =" + modlobj.getStatusID() + "";
            Cursor c = db.rawQuery(query, null);

            if (c.moveToFirst()) {
                VisitStatusUpdate(modlobj);
            } else {
                InsertVisit_Status(modlobj);
            }
            c.close();


          }
       private void VisitStatusUpdate(VisitStatusModel modlobj) {

            ContentValues contentValues = new ContentValues();
            String[] args = {String.valueOf(modlobj.getStatusID())};
             contentValues.put(VisitStatusModel.status,modlobj.getStatus());
            contentValues.put(VisitStatusModel.statusid,modlobj.getStatusID());
            db.update(VisitStatusModel.table, contentValues, VisitStatusModel.statusid + "= ?", args);
        }
  private void InsertVisit_Status(VisitStatusModel visitStatusModel) {
        ContentValues contentValues = new ContentValues();
        contentValues.put(VisitStatusModel.status, visitStatusModel.getStatus());
        contentValues.put(VisitStatusModel.statusid, visitStatusModel.getStatusID());

        mcontext.getContentResolver().notifyChange(VisitDAO_URI, null);
        db.insert(VisitStatusModel.table, null, contentValues);
    }

Can someone help me out. Thanks in advance!!
