How to remove or hide MarkerView in MPAndroidChart?

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; } ``` }
