MPchart Android中的重叠标签饼图

Question

我将mpchart库用于android stadio中的饼图。图表标签有不同数量的重叠部分。请帮助我。

   ArrayList<PieEntry> entries = new ArrayList<>();
    for (int i = 0; i < headerTitle.getContent().size(); i++) {
        ReportParameterModel.Data.ReportTypes.Content content = headerTitle.getContent().get(i);
        String s = content.getReportValue().toString().replace("-", "");
        entries.add(new PieEntry(Float.parseFloat(s), content.getReportDesc()));
    }
    PieDataSet pieDataSet = new PieDataSet(entries, "");
    PieData data = new PieData(pieDataSet);
    data.setValueFormatter(new PercentFormatter());
    pieDataSet.setDrawValues(true);

    pieDataSet.setXValuePosition(PieDataSet.ValuePosition.OUTSIDE_SLICE);
    pieDataSet.setYValuePosition(PieDataSet.ValuePosition.OUTSIDE_SLICE);
    data.setValueTextColor(G.context.getResources().getColor(R.color.title_color_dark));
    pieDataSet.setValueLinePart1Length(0.4f);
    pieDataSet.setValueLinePart2Length(0.3f);
    pieDataSet.setValueTextSize(12f);
    pieDataSet.setValueTextColor(G.context.getResources().getColor(R.color.title_color_dark));/* this line not working */
    pieDataSet.setValueTypeface(G.getFont());
    pieDataSet.setColors(getColors(headerTitle.getContent().size()));



    pieChart.setData(data);
    Description description = new Description();
    description.setText("");
    pieChart.setDescription(description);
