ich MPandroidchart verwende für die Ansicht Liniendiagramme in meinem application.I haben folgenden Code hinzugefügt Marker Ansicht zu zeigen, aber es zeigt nicht aufMarkerView nicht mit zeigt sich MPAndroidChart
private void initializeChart(LineChart chart, String chartName) {
// Chart view
chart.setDrawGridBackground(false);
chart.setDescription("");
chart.getLegend().setEnabled(true);
//chart.setTouchEnabled(false);
int color = getResources().getColor(R.color.white);
chart.getAxisLeft().setTextColor(color); // left y-axis
chart.getXAxis().setTextColor(color);
chart.setTouchEnabled(true);
CustomMarkerView mv = new CustomMarkerView(this.getActivity(), R.layout.marker_view_tv);
chart.setMarkerView(mv);
//X axis
XAxis xAxis = chart.getXAxis();
xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
xAxis.setDrawGridLines(false);
xAxis.setDrawLabels(true);
//Y axis
YAxis leftAxis = chart.getAxisLeft();
YAxis rightAxis = chart.getAxisRight();
rightAxis.setDrawLabels(false);
rightAxis.setDrawGridLines(false);
leftAxis.setDrawLabels(true);
leftAxis.setDrawGridLines(false);
leftAxis.setStartAtZero(false);
SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(getActivity());
leftAxis.setLabelCount(Constants.KEY_LINE_YAXIS_SCALECOUNT, true);
ChartItem item = CannonJsonParser.parseCanonJson(act, act.res);
int maxYVal = pref.getInt(Constants.KEY_YAXIS_VALUE, 0);
leftAxis.setAxisMaxValue(maxYVal);
leftAxis.setAxisMinValue(0);
setLineData(item, chartName);
// set data
chart.setData(lineData);
chart.getLegend().setEnabled(false);
//animate
//chart.animateX(2000, Easing.EasingOption.EaseInExpo);
chart.setDragEnabled(true);
chart.setScaleXEnabled(true);
chart.setScaleYEnabled(false);
chart.setHighlightPerDragEnabled(false);
chart.setHighlightPerTapEnabled(false);
}
Meine CustomMarkerView Klasse
public class CustomMarkerView extends MarkerView {
private TextView tvContent;
public CustomMarkerView(Context context, int layoutResource) {
super(context, layoutResource);
tvContent = (TextView) findViewById(R.id.tvContent);
}
// callbacks everytime the MarkerView is redrawn, can be used to update the
// content (user-interface)
@Override
public void refreshContent(Entry e, Highlight highlight) {
if (e instanceof CandleEntry) {
CandleEntry ce = (CandleEntry) e;
tvContent.setText("" + Utils.formatNumber(ce.getHigh(), 0, true));
} else {
tvContent.setText("" + Utils.formatNumber(e.getVal(), 0, true));
}
}
@Override
public int getXOffset(float xpos) {
// this will center the marker-view horizontally
return -(getWidth()/2);
}
@Override
public int getYOffset(float ypos) {
// this will cause the marker-view to be above the selected value
return -getHeight();
}
}
Hinweis: I-Fragment bin mit Diagrammen zu zeigen.
