java - 在 Android 中更改 GraphView 对象的网格颜色

Question

我添加了一个 GraphView 对象，并根据网站文档中的示例用一些数据填充了它。虽然我知道如何更改 GraphView 的背景颜色，但我不知道如何更改网格颜色。有任何想法吗？

这是我试过的:

public void createGraph(View view){
    GraphView graph = (GraphView) view.findViewById(R.id.graph);
    GridLabelRenderer gridLabelRenderer = graph.getGridLabelRenderer();

    // This works
    graph.setBackgroundColor(getResources().getColor(android.R.color.holo_green_light));

    // This does not work
    gridLabelRenderer.setGridColor(getResources().getColor(android.R.color.holo_green_light));

    // Nor does this
    //gridLabelRenderer.setGridColor(15);

    // This works
    LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(new DataPoint[] {
            new DataPoint(0, 1),
            new DataPoint(1, 5),
            new DataPoint(2, 3),
            new DataPoint(3, 2),
            new DataPoint(4, 6)
    });
    graph.addSeries(series);
}

尝试

        graph.getGridLabelRenderer().reloadStyles();
