无法在同一Android活动上重新创建Highcharts图

Question

I am using Android Highcharts Graph Library in my project.

https://github.com/highcharts/highcharts-android

I have Four Buttons Day, Hour, Minute, Week as below image.

When Activity starts first time it works fine, Graph is also showing correctly all things are working fine but when again API is hitting again on same activity response I am getting correctly but graph is not recreating.

I checked with LOG inside callGraphView() Log prints Correctly but no change detected in graph.

I also checked it without API but same thing happens again. In Web/iOS its working fine.

Below is the URL of This Graph :

https://www.highcharts.com/android/demo/line-basic

Below is my Code :

private void JsonRequestOrderVelocity(String dmhw) {
    utils.showDialog();

    String url = Constants.ORDER_VELOCITY_API+"stemSku=com-1&type="+dmhw+"&warehouse_id="+whareHouse;
    Log.e("URL", "" + url);

    JsonObjectRequest request = new JsonObjectRequest(url, null,
            response -> {
                Log.e("onResponse",""+response);
                try {
                    Gson gson = new Gson();
                    Type listType = new TypeToken<OrderVelocityPojo>() {}.getType();
                    orderVelocityPojo = gson.fromJson(response.toString(), listType);

                    if(dmhw.equalsIgnoreCase("day")){
                        callGraphView("Daily");
                    }else if(dmhw.equalsIgnoreCase("hour")){
                        callGraphView("Hourly");
                    }else if(dmhw.equalsIgnoreCase("minute")){
                        callGraphView("Minute-wise");
                    }else{
                        callGraphView("Weekly");
                    }
                        ...................
}

Answer 1

First Solution :

We can use HIChartView object like this: chartView.reload() after each request.

full Code :

 dayButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                manager.updateChart(chartView, c, "area", "DataSteps.json", "day");
                chartView.reload();
            }
        });
        weekButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                manager.updateChart(chartView, c, "area", "DataSteps.json", "week");
                chartView.reload();
            }
        });
        monthButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                manager.updateChart(chartView, c, "area", "DataSteps.json", "month");
                chartView.reload();
            }
        });
        yearButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                manager.updateChart(chartView, c, "area", "DataSteps.json", "year");
                chartView.reload();
            }
        });

Second Solution :

I solved this issue by myself, I created one fragment inside Activity for graph, also I'm hitting API inside fragment with highcharts-graphView.

So when i taps on any of them Day,Hour,Minute,Week button it creates fragment every time and graph showing.

Here is the code :

 @Override
public void onClick(View view) {
    if(view.getId()==R.id.btndayOV){

        OrderVelocityFragment fragment = new OrderVelocityFragment().newInstance(whareHouse,whareHouseName,"day");
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.content_frame_home, fragment)
                .commit();

        day.setTextColor(Color.WHITE);
        day.setBackgroundResource(R.color.orderVelocity);
        hour.setBackgroundResource(R.color.orderVelocityLight);
        minute.setBackgroundResource(R.color.orderVelocityLight);
        week.setBackgroundResource(R.color.orderVelocityLight);
    }
    else if(view.getId()==R.id.btnHourOV){

        OrderVelocityFragment fragment = new OrderVelocityFragment().newInstance(whareHouse,whareHouseName,"hour");
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.content_frame_home, fragment)
                .commit();

        hour.setTextColor(Color.WHITE);
        day.setBackgroundResource(R.color.orderVelocityLight);
        hour.setBackgroundResource(R.color.orderVelocity);
        minute.setBackgroundResource(R.color.orderVelocityLight);
        week.setBackgroundResource(R.color.orderVelocityLight);
    }
    else if(view.getId()==R.id.btnMinuteOV){

        OrderVelocityFragment fragment = new OrderVelocityFragment().newInstance(whareHouse,whareHouseName,"minute");
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.content_frame_home, fragment)
                .commit();

        minute.setTextColor(Color.WHITE);
        day.setBackgroundResource(R.color.orderVelocityLight);
        hour.setBackgroundResource(R.color.orderVelocityLight);
        minute.setBackgroundResource(R.color.orderVelocity);
        week.setBackgroundResource(R.color.orderVelocityLight);
    }
    else if(view.getId()==R.id.btnWeekOV){

        OrderVelocityFragment fragment = new OrderVelocityFragment().newInstance(whareHouse,whareHouseName,"week");
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.content_frame_home, fragment)
                .commit();

        week.setTextColor(Color.WHITE);
        day.setBackgroundResource(R.color.orderVelocityLight);
        hour.setBackgroundResource(R.color.orderVelocityLight);
        minute.setBackgroundResource(R.color.orderVelocityLight);
        week.setBackgroundResource(R.color.orderVelocity);
    }
}
