我想按产品名称对ListView的项目进行排序.我有一个名为"data"的向量,它是一种类.

我上课的是:

public static class RowData implements Comparable<RowData>{
    public String mProductName;
    protected int mId;

    protected int mOnHand;

        mOnHand =onhand;
        mPrice = price;
        mIsColleaction =IsColleaction;
        mIsPrePack = IsPrePack;
    }

    @Override
    public String toString() {
        return mProductName;
    }

    public int compareTo(RowData other) {
        return mProductName.compareTo(other.mProductName);
    }

    public static Comparator<RowData> COMPARE_BY_PRODUCTNAME = new Comparator<RowData>() {
        public int compare(RowData one, RowData …

我已经像下面提到的链接一样做了图像的联系人列表,

但问题是,当我点击字母表列表时,租船人没有显示,只有当我滚动浏览"setFastScrollEnabled"但我不想在我的屏幕上显示"FastScroll"时才会显示:这里是显示内容的链接我想要,
