How to remove or hide MarkerView in MPAndroidChart?

Question

I did a bar chart with MPAndroidChart. I did a custom marker view class to view the values of the bar.
I would remove or hide the view after some seconds. It should work as a toast. But I cannot do it.
This is a problem first of all because after I touched the chart for the first time, it becomes visible and it disappears only if i find the right tapped condition.

There is someone who knows how solve this problem?

In my code I have:

mChart.invalidate();
mv = new CustomMarkerView(getContext(), R.layout.alert_chart, position, jsonResponse);
mChart.setMarker(mv);

And my CustomMarkerView is

public class CustomMarkerViewextends MarkerView {

public TextView correct;
public TextView wrong ;
public int position;
public JSONArray jsonArray;

public CustomMarkerView(Context context, int layoutResource, int pos, JSONArray json) {
    super(context, layoutResource);

    correct = (TextView) findViewById(R.id.correct);
    wrong = (TextView) findViewById(R.id.wrong);

    position = pos;
    jsonArray = json;

}

@Override
public void refreshContent(Entry e, Highlight highlight) {
    switch (position){
        case 1:
            try {
                correct.setText(getContext().getString(R.string.correct_alert) + "   " + jsonArray.getJSONObject((int)(e.getX())).getString("TP"));
                wrong.setText(getContext().getString(R.string.wrong_alert) + "   " + jsonArray.getJSONObject((int)(e.getX())).getString("FP"));        
            } catch (JSONException e1) {
                e1.printStackTrace();
            } catch (ParseException e1) {
                e1.printStackTrace();
            }

            break;
        case 2:
            try {
                correct.setText(getContext().getString(R.string.tpr_alert) + "   " + Math.round(Double.parseDouble(jsonArray.getJSONObject((int)(e.getX())).getString("TPR"))*100.0)/100.0);
                wrong.setText(getContext().getString(R.string.msr_alert) + "   " + Math.round(Double.parseDouble(jsonArray.getJSONObject((int)(e.getX())).getString("MSR"))*100.0)/100.0);
            } catch (JSONException e1) {
                e1.printStackTrace();
            } catch (ParseException e1) {
                e1.printStackTrace();
            }

            break;
        case 3:
            try {
                correct.setText(getContext().getString(R.string.nmean_alert) + "   " +Math.round(Double.parseDouble(jsonArray.getJSONObject((int)(e.getX())).getString("n_mean"))*100.0)/100.0);
                wrong.setText(getContext().getString(R.string.nmax_alert) + "   " +Math.round(Double.parseDouble(jsonArray.getJSONObject((int)(e.getX())).getString("n_max"))*100.0)/100.0);
            } catch (JSONException e1) {
                e1.printStackTrace();
            } catch (ParseException e1) {
                e1.printStackTrace();
            }

            break;
    }

    // this will perform necessary layouting
    super.refreshContent(e, highlight);

}

private MPPointF mOffset;

@Override
public MPPointF getOffset() {

    if(mOffset == null) {
        // center the marker horizontally and vertically
        mOffset = new MPPointF(-(getWidth()/2), -getHeight());
    }

    return mOffset;
}

}

Answer 1

I know, it's a bit late, but:

mChart.highlightValue(null);

Worked for me

Answer 2

Set an onTouchListener to your chart and in the MotionEvent ACTION_UP set the highlight value to null. Code :

chart.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {

            switch (event.getAction()) {

                case MotionEvent.ACTION_UP: {
                    chart.highlightValue(null);
                    break;
                }
            }
            return false;
        }
    });
