Question

https://drive.google.com/open?id=1hc2BsawKmRoXsLhAuBlhNFLx_9zlEiWC

我的应用活动包括可滚动的布局，viewpager和recyclerview。 第一次加载时，所有viewpager中的所有recyclerview都能顺利运行。 问题是，当我滚动第3或第4个viewpager recyclerview时，然后我滑动回到第2个viewpager，我只是触摸了recyclerview列表，它崩溃了。 请帮助我...

def FormatChart(chart):
    plot = chart.plots[0]
    plot.has_data_labels = True
    dl = plot.data_labels
    dl.position = XL_LABEL_POSITION.OUTSIDE_END

    value_axis = chart.value_axis
    value_axis.has_major_gridlines = False

    s = plot.series[0]
    s.format.fill.solid()
    s.format.fill.fore_color.theme_color = MSO_THEME_COLOR_INDEX.ACCENT_1

运行中的错误提示
