带有滚动视图的mpAndroidChart折线图性能

• 问答

scrollView内有折线图，我的所有数据都是7点，滚动屏幕时有滞后， 我尝试使用nestedScrollview或禁用图表可访问性，但仍然有滞后。 当图表没有数据时，scrollView会非常平滑，但是当我在图表上设置数据时，滚动效果不好

这是设置程序类

public class Setupcharts {

    public LineData drawChart(Context context,ArrayList<Entry> entries,LineChart chart,String[] labels) {

            if (entries.size() > 0) {

                //customization dataSet Settings
                LineDataSet set = new LineDataSet(entries,"");
                set.setaxisDependency(YAxis.AxisDependency.LEFT);
                set.setDrawValues(true);
                set.setLineWidth(3f);
                set.setDrawCircles(true);
                set.setvalueTextSize(12f);
                set.setMode(LineDataSet.Mode.CUBIC_BEZIER);
                set.setvalueTextColor(context.getResources().getcolor(R.color.progress));
                set.setColor(context.getResources().getcolor(R.color.progress));
                set.setCircleColor(context.getResources().getcolor(R.color.progress));

                //customization chart settings
                chart.setNoDataText("No data");
                chart.setTouchEnabled(false);
                chart.setDragEnabled(false);
                chart.setDrawGridBackground(false);
                chart.getDescription().setEnabled(false);
                chart.setPinchzoom(false);
                chart.setnestedScrollingEnabled(false);

                chart.getLegend().setEnabled(false);

                if (labels != null) {

                    //customization XAxis settings
                    XAxis x1 = chart.getXAxis();
                    x1.setTextColor(context.getResources().getcolor(R.color.progress));
                    x1.setDrawGridLines(false);
                    x1.setavoidFirstLastClipping(true);
                    x1.setPosition(XAxis.XAxisPosition.BOTTOM);
                    x1.setvalueFormatter(new IndexAxisValueFormatter(labels));
                    x1.setLabelCount(labels.length,true);

                }

                //customization YAxis settings
                YAxis y1 = chart.getaxisLeft();
                y1.setDrawLabels(false);
                y1.setTextColor(Color.BLACK);
                y1.setDrawGridLines(false);


                YAxis y2 = chart.getaxisRight();
                y2.setEnabled(false);

                LineData data = new LineData(set);

                //set custom font
                Typeface face = Typeface.createFromAsset(context.getassets(),"Shabnamn.ttf");
                data.setvalueTypeface(face);
                chart.getXAxis().setTypeface(face);

                return data;

            }else
                return null;
    }
}

和活动中

public void parseResponse（字符串响应）{

ArrayList<Entry> entries = new ArrayList<>();

try {
    JSONObject object = new JSONObject(response);

    JSONArray array = object.getJSONArray("summary");

    labels = new String[array.length()];

    int j = 0;
    for (int i = array.length() - 1; i >= 0; i--) {

        JSONObject object1 = array.getJSONObject(i);

        int y = object1.getInt("burnt_calory");
        entries.add(new Entry(j,y));

        date = object1.getString("at_date");

        j++;
    }

} catch (JSONException e) {
    e.printStackTrace();
    Log.i("action response catch","error");

}

LineData data = new  
 Setupcharts().drawChart(actionactivity.this,entries,chart,labels);
chart.setData(data);
chart.animateY(55*35,Easing.Linear);

}
