Android - 片段

Question

喜？我Fragment RecyclerView Adapter RecyclerView setOnClickListener我希望getSupportFragmentManager().add()打开另一个片段，只有getSupportFragmentManager()，但我无法拨打支持Constructor。

这是我的适配器fragment1 f1; public Adapters(Context context){ f1 = (fragment1)context; //here has error } ：

onClickListener

这是我的fragment2 frg = new fragment2(); f1.getSupportFragmentManager.beginTransaction().add(R.id.idLayout, frg).commit(); ：

Private Sub ExportToExcel(ByVal dtTemp As DataTable, ByVal filepath As String)
        Dim strFileName As String = filepath
        Dim _excel As New Excel.Application
        Dim wBook As Excel.Workbook
        Dim wSheet As Excel.Worksheet

        Dim newCulture As System.Globalization.CultureInfo
        Dim OldCulture As System.Globalization.CultureInfo

        OldCulture = System.Threading.Thread.CurrentThread.CurrentCulture
        newCulture = New System.Globalization.CultureInfo( _
            _excel.LanguageSettings.LanguageID(Office.MsoAppLanguageID.msoLanguageIDUI))
        System.Threading.Thread.CurrentThread.CurrentCulture = newCulture

        wBook = _excel.Workbooks.Add()
        wSheet = wBook.ActiveSheet()

        Dim dt As System.Data.DataTable = dtTemp
        Dim dc As System.Data.DataColumn
        Dim dr As System.Data.DataRow
        Dim colIndex As Integer = 0
        Dim rowIndex As Integer = 0

        For Each dc In dt.Columns
            colIndex = colIndex + 1
            wSheet.Cells(1, colIndex) = dc.ColumnName
        Next

        For Each dr In dt.Rows
            rowIndex = rowIndex + 1
            colIndex = 0
            For Each dc In dt.Columns
                colIndex = colIndex + 1
                wSheet.Cells(rowIndex + 1, colIndex) = dr(dc.ColumnName)
            Next
        Next
        wSheet.Columns.AutoFit()
        wBook.SaveAs(strFileName)

        _excel.Visible = True

    End Sub

如何getSupportFragmentManager？

我已经解决了我的问题，从Object创建了新的fragment1并将其用于getSupportFragmentManager。
