如何在MpAndroidChart中更改网格线的某些部分的颜色

public class CustomAxisRenderer extends XAxisRenderer {
    private int customGridLineColor = Color.RED;

    public CustomAxisRenderer(XAxis xAxis, ViewPortHandler viewPortHandler, Transformer transformer) {
        super(xAxis, viewPortHandler, transformer);
    }

    @Override
    public void drawGridLine(Canvas c, float x, float y, Path gridLinePath) {
        if (x == 0 || x == mViewPortHandler.contentRight()) {
            // 修改网格线的颜色
            mGridPaint.setColor(customGridLineColor);
        } else {
            // 使用默认的网格线颜色
            mGridPaint.setColor(mXAxis.getGridColor());
        }

        super.drawGridLine(c, x, y, gridLinePath);
    }
}

public class CustomLineChart extends LineChart {
    public CustomLineChart(Context context) {
        super(context);
        init();
    }

    public CustomLineChart(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public CustomLineChart(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    private void init() {
        XAxis xAxis = getXAxis();
        YAxis yAxis = getAxisLeft();

        CustomAxisRenderer customAxisRenderer = new CustomAxisRenderer(xAxis, mViewPortHandler, mLeftAxisTransformer);
        xAxis.setRenderer(customAxisRenderer);
        yAxis.setRenderer(customAxisRenderer);
    }
}

// 在Activity或Fragment中使用CustomLineChart
CustomLineChart lineChart = findViewById(R.id.lineChart);
lineChart.setData(data); // 设置数据
lineChart.invalidate(); // 刷新图表
