android - HighChart 库 Android : HIOptions not found in HIChartView

Question

我正在尝试将 highcharts 集成到我的 android 应用程序中(在 fragment 内)，但我每次都会收到此错误:

java.util.NoSuchElementException: HIOptions not found in HIChartView

这是我的 onCreateView 方法:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        parentView = inflater.inflate(R.layout.bar_layout, null);
        return parentView;
    }

我如何获得图 TableView :

chartView = parentView.findViewById(R.id.hc);

我正在调用图表 API 以在收到响应后获取数据，我正在设置选项但它给了我同样的错误，下面是我如何设置图表的代码 fragment :

                HIOptions options = new HIOptions();

                HIChart chart = new HIChart();
                chart.setType("column");
                options.setChart(chart);

                HIExporting hiExporting = new HIExporting();

                    xAxis.setTitle(xAxisTitle);

                    XAxisDto xAxisDto = barChartModel.getxAxis();

                    plotOptions.setColumn(hiColumn);
                    options.setPlotOptions(plotOptions);

我在这里错过了什么？或者如何解决这个问题？

Answer 1

我能够解决这个问题。

按照以下步骤解决问题:

1. 当 fragment View 可见时

2. 获取图表 ID

   chartView = parentView.findViewById(R.id.hc);

3. 为 chartView 设置空选项:

   HIOptions options = new HIOptions();
   
   chartView.setOptions(options);
   

4. 从 API 中获取数据后，再次将选项设置为 chartView 并调用重新加载方法:

   chartView.setOptions(options);
   chartView.reload();
