Setting the pie slice colors in MPAndroidChart

Question

I need to define specific hex values for each slice in my pie chart.

I'm following the wiki but the method doesn't seem to be working for PieDataSet

PieDataSet dataSet = new PieDataSet(entries, "Fuel");
dataSet.setColors(new int[] { R.color.green1, R.color.green2, R.color.green3, R.color.green4 }, Context);

These errors are shown:

Cannot resolve symbol 'green1'

Expression expected  <-- At the 'Context'

Is there an alternate way to set the pie slice color? This seems to work for Line charts but not for pie.

Answer 1

Found a work around:

final int[] MY_COLORS = {Color.rgb(192,0,0), Color.rgb(255,0,0), Color.rgb(255,192,0),Color.rgb(127,127,127), Color.rgb(146,208,80), Color.rgb(0,176,80), Color.rgb(79,129,189)};

ArrayList<Integer> colors = new ArrayList<Integer>();
        
for(int c: MY_COLORS) colors.add(c);
        
dataSet.setColors(colors);

Answer 2

use ContextCompat.getColor(context, R.color.green1) instead of R.color.green1 if not colors will not shown properly.

example code in Kotlin :

 val colorFirst = context?.let { ContextCompat.getColor(it, R.color.colorFirst) }
 val colorSecond = context?.let { ContextCompat.getColor(it, R.color.colorSecond) }
 val colorThird = context?.let { ContextCompat.getColor(it, R.color.colorThird) }

 pieDataSet.colors = mutableListOf(colorFirst, colorSecond, colorThird)
