Answer 1

将此代码放入列表视图

android:cacheColorHint = "#000000". 

Answer 2

只需更改

即可

if(position-1==listPaymenIdA.size()-1){
        //AppLog.logString(TAG+"if: "+position);
        int color=getResources().getColor(R.color._90ffffff);
        holder.txtInvoiceNo.setBackgroundColor(color);
        holder.txtDate.setBackgroundColor(color);
        holder.txtPamentAmount.setBackgroundColor(color);
        holder.txtPaymentMode.setBackgroundColor(color);

        holder.txtInvoiceNo.setTypeface(null, Typeface.BOLD);
        holder.txtDate.setTypeface(null, Typeface.BOLD);
        holder.txtPamentAmount.setTypeface(null, Typeface.BOLD);
        holder.txtPaymentMode.setTypeface(null, Typeface.BOLD);

        holder.txtInvoiceNo.setText("");
        holder.txtDate.setText("Total ");
        holder.txtPamentAmount.setText(""+round(total));
        holder.txtPaymentMode.setText("");
    }else{
        //AppLog.logString(TAG+"else: "+position);
        Date date1 = null;
        try {
            date1 = new SimpleDateFormat("yyyy/MM/dd").parse(listDateA.get(position));
        } catch (ParseException e) {
            e.printStackTrace();
        }

        int color=getResources().getColor(R.color._10ffffff);//normal color which display
        holder.txtInvoiceNo.setBackgroundColor(color);
        holder.txtDate.setBackgroundColor(color);
        holder.txtPamentAmount.setBackgroundColor(color);
        holder.txtPaymentMode.setBackgroundColor(color);

        holder.txtInvoiceNo.setTypeface(null, Typeface.NORMAL);
        holder.txtDate.setTypeface(null, Typeface.NORMAL);
        holder.txtPamentAmount.setTypeface(null, Typeface.NORMAL);

        formatterYY = new SimpleDateFormat("dd/MM/yyyy", Locale.US);
        String todaye = formatterYY.format(date1);
        holder.txtInvoiceNo.setText(""+listidA.get(position));

        holder.txtPamentAmount.setText(""+round(lisTotalAMTA.get(position)));
    }
