MPAndroidChart: getColors() is now deprecated for 'Legend'. What should I use instead?

问题

I'm displaying a custom legend for a PieChart in MPAndroidChart however, .getColors() and .getLabels() are now deprecated.

I've been using them to get an int array and string array respectively but I can't seem to find a direct alternative. Am I missing something obvious? What should I now use instead? Thanks!

Legend legend = mChart.getLegend();
legend.setEnabled(false);

if (legend.getColors() != null) {

    int colorCodes[] = legend.getColors();
    String labels[] = legend.getLabels();

    ArrayList<LegendItem> legendItems = new ArrayList<>();

    for (int i = 0; i < legend.getColors().length-1; i++) {
        legendItems.add(new LegendItem(colorCodes[i], labels[i]));
    }

    showLegend(legendItems);

    // entry label styling
    mChart.setDrawEntryLabels(false);

}

The Legend class now follows better OOP practices and is composed of an array of LegendEntry. You can iterate through each and extract the colors or the labels as you wish.

private int [] getColors(Legend legend) {
    LegendEntry [] legendEntries = legend.getEntries();
    int [] colors = new int[legendEntries.length];
    for (int i = 0; i < legendEntries.length; i++) {
        colors[i] = legendEntries[i].formColor;
    }
    return colors;
}

private String [] getLabels(Legend legend) {
    LegendEntry [] legendEntries = legend.getEntries();
    String [] labels = new String[legendEntries.length];
    for (int i = 0; i < legendEntries.length; i++) {
        labels[i] = legendEntries[i].label;
    }
    return labels;
}
