You can use the method public void highlightValues(Highlight[] highs) to highlight values.

Example

Highlight h = new Highlight(x-index, dataSetIndex); // dataset index for piechart is always 0
chart.highlightValues(new Highlight[] { h });

I try this, but it not trigger OnChartValueSelectedListener() , what should I do ? @PhilJay

[PhilJay]

If you want to trigger the listener, call highlightTouch(...)

Hi!
I click a value on the graph and it gets selected. When I then call highlightValues(...) or highlightTouch(...) it gets deselected, but the next click on the graphic is ignored. It looks like it's waiting for that click to deselect the value...

Is there a way around this behavior?

Thanks!

@Manhazito Hi !

Did you find the solution ?
I have the same problem ... I still need to click twice on the slice to re-select it ...

thx

I leave a comment for you guys.
I could call onValueSelected() in my RecyclerView Adapter.

pieChart.highlightValue(highlight, true);

 @Override
    public void onBindViewHolder(ViewHolder holder, int position) {

        holder.rl_root.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Highlight highlight = new Highlight((float)position, 0.0f, 0);
                //pieChart.highlightValue(highlight); //doesn't call onValueSelected()
                pieChart.highlightValue(highlight, true); //call onValueSelected()
            }
        });

    }
