Question

我在这里遇到了一些问题（你可能想象......：D）

这是有问题的代码：

using (SpreadsheetDocument document = SpreadsheetDocument.Create(filename, SpreadsheetDocumentType.Workbook))
{
    //fluff to generate the workbook etc
    WorkbookPart workbookPart = document.AddWorkbookPart();
    workbookPart.Workbook = new Workbook();

    var worksheetPart = workbookPart.AddNewPart<WorksheetPart>();
    worksheetPart.Worksheet = new Worksheet();

    Sheets sheets = workbookPart.Workbook.AppendChild(new Sheets());

    Sheet sheet = new Sheet() { Id = workbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "Sheet" };
    sheets.Append(sheet);

    workbookPart.Workbook.Save();

    var sheetData = worksheetPart.Worksheet.AppendChild(new SheetData());

    //add the style
    Stylesheet styleSheet = new Stylesheet();

    CellFormat cf = new CellFormat();
    cf.NumberFormatId = 14;
    cf.ApplyNumberFormat = true;

    CellFormats cfs = new CellFormats();
    cfs.Append(cf);
    styleSheet.CellFormats = cfs;

    styleSheet.Borders = new Borders();
    styleSheet.Borders.Append(new Border());
    styleSheet.Fills = new Fills();
    styleSheet.Fills.Append(new Fill());
    styleSheet.Fonts = new Fonts();
    styleSheet.Fonts.Append(new Font());

    workbookPart.AddNewPart<WorkbookStylesPart>();
    workbookPart.WorkbookStylesPart.Stylesheet = styleSheet;

    CellStyles css = new CellStyles();
    CellStyle cs = new CellStyle();
    cs.FormatId = 0;
    cs.BuiltinId = 0;
    css.Append(cs);
    css.Count = UInt32Value.FromUInt32((uint)css.ChildElements.Count);
    styleSheet.Append(css);

    Row row = new Row();

    DateTime date = new DateTime(2017, 6, 24);

    /*** Date code here ***/
    //write an OADate with type of Number
    Cell cell1 = new Cell();
    cell1.CellReference = "A1";
    cell1.CellValue = new CellValue(date.ToOADate().ToString());
    cell1.DataType = new EnumValue<CellValues>(CellValues.Number);
    cell1.StyleIndex = 0;
    row.Append(cell1);

    //write an OADate with no type (defaults to Number)
    Cell cell2 = new Cell();
    cell2.CellReference = "B1";
    cell2.CellValue = new CellValue(date.ToOADate().ToString());
    cell1.StyleIndex = 0;
    row.Append(cell2);

    //write an ISO 8601 date with type of Date
    Cell cell3 = new Cell();
    cell3.CellReference = "C1";
    cell3.CellValue = new CellValue(date.ToString("yyyy-MM-dd"));
    cell3.DataType = new EnumValue<CellValues>(CellValues.Date);
    cell1.StyleIndex = 0;
    row.Append(cell3);

    sheetData.AppendChild(row);

    worksheetPart.Worksheet.Save();
}

所以，正如你所看到的，我有一个imageView，我需要以编程方式进行调整。然后我设置LayoutParams并将它们（2x！）交给ImageView。但是，无论我如何设置它们 - 都没有任何反应。 ImageView仍然和以前一样。这让我发疯了。

任何帮助？

谢谢！

根据您的代码viewPager.AddView(imageView, param);，您希望将图片添加到ViewPager，然后LayoutParams应为ViewPager.LayoutParams，应该为添加到ViewPager。

但是我不认为设置LayoutParams ImageView这里应该解决你的问题，我想你想要填写{{{{{{ 1}}带图像。然后你需要拉伸图像。

因此，您可以尝试更改代码：

ViewPager

Android的; xamarin：LayoutParams被忽略了......？
