您可以使用以下方法制作 MPAndroidChart PieChart。
private fun setPieChartData(view: View) {
val listPie = ArrayList<PieEntry>()
val listColors = ArrayList<Int>()
listPie.add(PieEntry(20F, "Pass"))
listColors.add(resources.getColor(R.color.color_result_pass))
listPie.add(PieEntry(50F, "Fail"))
listColors.add(resources.getColor(R.color.color_result_fail))
listPie.add(PieEntry(30F, "Unanswered"))
listColors.add(resources.getColor(R.color.colorPrimary))
val pieDataSet = PieDataSet(listPie, "")
pieDataSet.colors = listColors
val pieData = PieData(pieDataSet)
pieData.setValueTextSize(CommonUtils.convertDpToSp(14))
view.pieChart.data = pieData
view.pieChart.setUsePercentValues(true)
view.pieChart.isDrawHoleEnabled = false
view.pieChart.description.isEnabled = false
view.pieChart.setEntryLabelColor(R.color.color_black)
view.pieChart.animateY(1400, Easing.EaseInOutQuad)
}
您可以根据您的要求进行定制。希望对你有帮助,谢谢。
