创建以英尺为单位转换的cms中的值列表

Question

我有一个以英尺为单位的高度值列表。如果用户将高度指标从英寸英寸更改为厘米，则列表会以厘米为单位显示所有值。

这是我的英尺高度代码：

 HorizontalPicker heightPicker = (HorizontalPicker) view.findViewById(R.id.heightPicker);


    final ArrayList<CharSequence> heightArray = new ArrayList<CharSequence>();
    for (int index = 3; index < 7; index++) {
        for (int index1 = 0; index1 < 12; index1++) {
            heightArray.add(index + "." + index1 + "\"");
            if (index == 6 && index1 == 4) {
                break;
            }
        }
    }



    CharSequence[] height1 = new CharSequence[heightArray.size()];
    final CharSequence[] height = heightArray.toArray(height1);

    heightPicker.setValues(height);

    heightPicker.setOnItemSelectedListener(new HorizontalPicker.OnItemSelected() {
        @Override
        public void onItemSelected(int index) {
            double heightInt = 0;
            try {
                heightInt = Double.parseDouble(trimLastChar(height[index].toString()));
            } catch (NumberFormatException ex) {
                ex.printStackTrace();
            }
            userProfile.setHeight(heightInt);
        }
    });

有人可以帮帮我吗？
