android - Anonymous bug in TextView -


i developing restaurant app. here use cart page view food items user selected checkout. cart items listed using recyclerview having + & - button increase & decrease product count before checkouts. problem @ here.

let consider items follows:

                                   result textview chocobar    rs25     -   4   +   =      100      // expected result  vennila     rs30     -   1   +   =      30

while clicking "+" button in chocobar

                                  result textview chocobar    rs25     -   5   +   =       100   ( set 125 within fraction of second changed 100)       vennila     rs30     -   1   +   =        30

but if use gettext,

resulttextview nothing in code used holder.cartpricedum

resulttextview.gettext().tostring --> returns 125 chocobar's item values.

gettext works settext not worked. gettting messup. please me, spent more time fix it.still have not fixed it.

mycode follows:

holder.ivincrease.setonclicklistener(new view.onclicklistener() {      public void onclick(view arg0) {         clicked = true;          cartprice = integer.parseint(holder.cartprice.gettext().tostring());         indequantity = integer.parseint(holder.cartcount.gettext().tostring());         if (null != mlistener) {             cartres.get(position).cartcount = (bigint + 1);             notifyitemchanged(position);             mlistener.onlistfragmentinteraction(holder.cartress);         }         updatecart(arg0);     }      private void updatecart(view view) {         string pid = cartres.get(position).product_id;         int cartprice = integer.parseint(holder.cartprice.gettext().tostring());         int cartindividualtotal = cartres.get(position).subtotal;          int cartcount = cartres.get(position).cartcount;          system.out.println("restaurant" + "   check" + "product id  " + pid + "cart price " + cartprice +                  " cartindividual total  " + cartindividualtotal + " cartcount " + cartcount);          commonutil.dbutil.open();         commonutil.dbutil.updateaddtocart(pid, cartprice, cartcount, cartindividualtotal);         total = commonutil.dbutil.getmultiply(pid);         commonutil.dbutil.updatenetamount(pid, total);         setcartprice(pid, holder);         view.invalidate();          /*--- set updated value cartres class---*/          system.out.println("cart details" + cartres.get(position).product_id + "  " +                 cartres.get(position).cartproductname + "  " + cartres.get(position).cartcategoryname +                 " " + cartcount + "  " + cartprice + "  " + total);          cartres cartbasket = new cartres(cartres.get(position).product_id, cartres.get(position).                 cartproductname, cartres.get(position).cartcategoryname,                 cartcount, cartprice, total);     } });  /*======================================= *** ==============================================*/  /*--- if cart count 1, disable decrement icon*/ if (indequantity <= 1) {     holder.ivdecrease.setvisibility(view.invisible); } else {     holder.ivdecrease.setvisibility(view.visible); }  /*====================================  decreasing cart ====================================*/  holder.ivdecrease.setonclicklistener(new view.onclicklistener() {      public void onclick(view arg0) {         clicked = true;          cartprice = integer.parseint(holder.cartprice.gettext().tostring());         indequantity = integer.parseint(holder.cartcount.gettext().tostring());         if (null != mlistener) {             if (indequantity > 1) {                 cartres.get(position).cartcount = (bigint - 1);                 notifyitemchanged(position);                 mlistener.onlistfragmentinteraction(holder.cartress);             } else if (indequantity <= 0) {                 indequantity = 1;             }         }         updatecart(arg0);     }      private void updatecart(view view) {         string pid = cartres.get(position).product_id;         int cartprice = integer.parseint(holder.cartprice.gettext().tostring());         int cartcount = cartres.get(position).cartcount;         int cartindividualtotal = cartres.get(position).subtotal;           commonutil.dbutil.open();         commonutil.dbutil.updateaddtocart(pid, cartprice, cartcount, cartindividualtotal);         system.out.println("restaurant " + pid + "  " + cartprice + " " + cartcount + " " + cartindividualtotal);         total = commonutil.dbutil.getmultiply(pid);          commonutil.dbutil.updatenetamount(pid, total);         setcartprice(pid, holder);          view.invalidate();          system.out.println("cart details" + cartres.get(position).product_id + "  " +                 cartres.get(position).cartproductname + "  " + cartres.get(position).cartcategoryname +                 " " + cartcount + "  " + cartprice + "  " + total);          cartres cartbasket = new cartres(cartres.get(position).product_id,                 cartres.get(position).cartproductname,                 cartres.get(position).cartcategoryname,                 cartcount, cartprice, total);     } });  private void setcartprice(string pid, viewholder holder) {     cursor cursor = commonutil.dbutil.getcartindividualprice(pid);     if (cursor != null && cursor.movetofirst()) {         int cartindividualtotal = integer.parseint(cursor.getstring(cursor.getcolumnindex(dbhelper.cart_total)));          holder.cartpricedum.settext(string.valueof(cartindividualtotal));          log.e("restaurant", " adaptercheck" + cartindividualtotal + " " + holder.cartpricedum.gettext().tostring());     } }

you invalidating view. after setcartprice(pid, holder); view.invalidate();

whenever invalidate view, view start redraw including child views. may why resets default value.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
