这代码写的也“没有谁了”

    if (isVote.equals("Y")&&"N".equals(isUpdate)) { 
            CreateNumberColorList();
            List<String> countList = datas.get(position).getCountList();
            String max = Collections.max(countList);
            Integer maxNumber = Integer.valueOf(max);

            for(int i = 0;i<datas.get(position).getCountList().size();i++){ //循环添加

                LinearLayout pollNumberView =  (LinearLayout) View.inflate(ctx, R.layout.poll_column_view, null); //柱状图 view
                TextView column_alphabet = (TextView) pollNumberView.findViewById(R.id.tv_column_alphabet); //字母
                TextView total_ticket = (TextView) pollNumberView.findViewById(R.id.tv_total_ticket); //选项被投票数
                ProgressBar pb = (ProgressBar) pollNumberView.findViewById(R.id.pb); //进度条
                 //设置最大值
            if (datas.get(position).getTpleVoteOption().size()==datas.get(position).getCountList().size()){

                switch (i%10) { //先设置颜色gmf
                case 0:
                    pb.setProgressDrawable(voteDrawable.get(0));
                    break;
                case 1:
                    pb.setProgressDrawable(voteDrawable.get(1));
                    break;
                case 2:
                    pb.setProgressDrawable(voteDrawable.get(2));
                    break;
                case 3:
                    pb.setProgressDrawable(voteDrawable.get(3));
                    break;
                case 4:
                    pb.setProgressDrawable(voteDrawable.get(4));
                    break;
                case 5:
                    pb.setProgressDrawable(voteDrawable.get(5));
                    break;
                case 6:
                    pb.setProgressDrawable(voteDrawable.get(6));
                    break;
                case 7:
                    pb.setProgressDrawable(voteDrawable.get(7));
                    break;
                case 8:
                    pb.setProgressDrawable(voteDrawable.get(8));
                    break;
                case 9:
                    pb.setProgressDrawable(voteDrawable.get(9));
                    break;

                default:
                    break;
                }
                column_alphabet.setText(letter[i]);
                total_ticket.setText(datas.get(position).getCountList().get(i)+"票");
                pb.setProgress((Integer.valueOf(datas.get(position).getCountList().get(i))));
                pb.setMax(maxNumber);
                pb.setBackgroundColor(color.holo_green_dark);
                holder.ll_column.addView(pollNumberView);
             }
            }

以上写的代码，也是可以看出你的实际开发经验
对于这段代码我们写得有多么的繁琐：

    switch (i%10) { //先设置颜色gmf
                case 0:
                    pb.setProgressDrawable(voteDrawable.get(0));
                    break;
                case 1:
                    pb.setProgressDrawable(voteDrawable.get(1));
                    break;
                case 2:
                    pb.setProgressDrawable(voteDrawable.get(2));
                    break;
                case 3:
                    pb.setProgressDrawable(voteDrawable.get(3));
                    break;
                case 4:
                    pb.setProgressDrawable(voteDrawable.get(4));
                    break;
                case 5:
                    pb.setProgressDrawable(voteDrawable.get(5));
                    break;
                case 6:
                    pb.setProgressDrawable(voteDrawable.get(6));
                    break;
                case 7:
                    pb.setProgressDrawable(voteDrawable.get(7));
                    break;
                case 8:
                    pb.setProgressDrawable(voteDrawable.get(8));
                    break;
                case 9:
                    pb.setProgressDrawable(voteDrawable.get(9));
                    break;

                default:
                    break;

其实我们完全可以用一行代码写

  pb.setProgressDrawable(voteDrawable.get(i%10));

如果i=0时 看看其实走的就是这一句代码

case:0
pb.setProgressDrawable(voteDrawable.get(0));
                    break;

那么我们换成这一行代码 pb.setProgressDrawable(voteDrawable.get(i%10));
只要用一个i%10 我们在for循环里 随着i的值变化 我们便可以把所有颜色设置上了。

以上代码其实 是一个投票 的 progressbar 循环添加到一个线性布局上，但在设置颜色的时候会出现问题 如果一个题目多于10个选项 也就是 a-n 如果超过10个progressbar设置的颜色便会出现问题。

<script type="text/javascript"> $(function () { $('pre.prettyprint code').each(function () { var lines = $(this).text().split('\n').length; var $numbering = $('<ul/>').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i <= lines; i++) { $numbering.append($('<li/>').text(i)); }; $numbering.fadeIn(1700); }); }); </script>
