How to remove the decimal point and retain percentage in PieChart values?

I am using MPAndroidChart library to make a pie chart. I would like to display the pie chart values with the decimal. I want to retain the % sign.

This solution to an old similar question is not valid since the release of version 3.0.0 of MPAndroidChart

UPDATE: This is the updated way of removing decimals

public class DecimalRemover extends DefaultValueFormatter {
private int digits;

public DecimalRemover(int digits) {
    super(digits);
    this.digits = digits;
}

@Override
public int getDecimalDigits() {
    return digits;
}
}

But even if I did pieChart.setUsePercentValues(true);, the "%" symbol is not being shown

In the setData() method:

 PieData data = new PieData(dataSet);
 data.setValueFormatter(new DecimalRemover(new DecimalFormat("###,###,###")));

Here is the DecimalRemover class:

public class DecimalRemover extends PercentFormatter {

protected DecimalFormat mFormat;

public DecimalRemover(DecimalFormat format) {
    this.mFormat = format;
}

@Override
public String getFormattedValue(float value, Entry entry, int dataSetIndex, ViewPortHandler viewPortHandler) {
    return mFormat.format(value) + " %";
}
}
