在 MPAndroidChart 中设置饼图切片颜色 [英] Setting the pie slice colors in MPAndroidChart

问题描述

我需要为饼图中的每个切片定义特定的十六进制值.

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

我正在关注 wiki 但该方法似乎没有正在为 PieDataSet

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);

显示这些错误:

Cannot resolve symbol 'green1'

Expression expected  <-- At the 'Context'

是否有其他方法可以设置饼图切片颜色?这似乎适用于折线图，但不适用于饼图.

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

推荐答案

找到了解决方法:

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);
