Android ScrollView不使用aChartEngine

我试图在一个活动中放置多个图表，并使用滚动视图查看所有图表

前两张图表出现了，但后两张没有。我遵循了教程中的所有说明，也遵循了有关stack的所有建议，但都不起作用

我也尝试过删除scrollview，但图表仍然无法显示。任何帮助都将不胜感激

XML:

使用滚动视图作为父布局而不是相对布局

您不能在滚动视图内滚动：

正如我在上面看到的，你使用

 <ScrollView>
 </ScrollView> 

---

在它里面嵌入了一些布局，其中包含需要滚动的图表，不幸的是，嵌套的滚动似乎不起作用。

嘿，你想滚动什么，但有一点点confused@DIVA通过将图表嵌入布局以编程方式添加的图表

public class LineGraph extends Activity{

    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();    
    protected static GraphicalView mChartView;

    public GraphicalView getView(Context context, int[]z, int []zz){

        CategorySeries series = new CategorySeries("line1");


    for(int i=0;i<z.length;i++){
        series.add("Bar " + (i+1),z[i]);
    }


    CategorySeries series2= new CategorySeries("demo");
    for(int i=0;i<zz.length;i++){
        series2.add("Bar " + (i+1),zz[i]);
    }

    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    dataset.addSeries(series.toXYSeries());
    dataset.addSeries(series2.toXYSeries());

    XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
    mRenderer.setAxesColor(Color.GREEN);

    XYSeriesRenderer renderer = new XYSeriesRenderer();
    renderer.setDisplayChartValues(true);
    renderer.setChartValuesSpacing((float)0.5);
    mRenderer.addSeriesRenderer(renderer);

    mRenderer.setZoomEnabled(false);
    mRenderer.setPanEnabled(false);
    mRenderer.setZoomRate(6.0f);
    mRenderer.setShowLabels(true);
    mRenderer.setFitLegend(true);
    mRenderer.setInScroll(true); 


    XYSeriesRenderer renderer2 = new XYSeriesRenderer();
    renderer.setColor(Color.CYAN);
    renderer.setDisplayChartValues(true);
    mRenderer.addSeriesRenderer(renderer2);




        return ChartFactory.getLineChartView(context, dataset, mRenderer);
