Java 如何获取项目的位置'；什么是儿童观？

在列表视图中，我以编程方式创建了图像视图，并将其添加到ListView项内部的线性布局中。然后如何得到图像的位置

下面我添加了getView（）方法。我在“String[]childDocument”中得到多个图像。使用for loop I从字符串[]和外接程序线性布局中提取图像

    @NonNull
@Override
public View getView(final int position, View convertView, @NonNull ViewGroup parent) {
    final ApproveReimbBin item = getItem(position);
    FoldingCell cell = (FoldingCell) convertView;
    final ViewHolder viewHolder;

    String date = item.getStr_startDate();
    String[] splitDate = date.split("To");

    String profileName = item.getStr_name();
    String profileEmpId = item.getStr_empId();
    String profileType = item.getStr_type();
    String profileAmount = item.getStr_amount();
    final String[] childDocument = item.getStr_documents();

    if (cell == null) {
        viewHolder = new ViewHolder();
        LayoutInflater vi = LayoutInflater.from(getContext());
        cell = (FoldingCell) vi.inflate(R.layout.adapter_approvereimburs, parent, false);

        // binding view parts to view holder
        viewHolder.imag_listProfileImage = cell.findViewById(R.id.list_image);
        viewHolder.txt_listName = cell.findViewById(R.id.list_profileName);
