Highchart Android How to implement drilldown in loop - highcharts

Question

My problem is in the drilldown. I want to create a drilldown on loop but all drilldown series show in one serie, the result is when I click on column, all drilldowns series show in that char.
ArrayList<Object> dataMinorAlarms = new ArrayList<>();
ArrayList<Object> dataMajorAlarms = new ArrayList<>();
ArrayList<Object> dataCriticalAlarms = new ArrayList<>();
ArrayList<Object> dataDrilldownlAlarms = new ArrayList<>();
ArrayList<Object> DrilldownlAlarms = new ArrayList<>();
for (ResumenGraph data:resumenGraphs){
HashMap<String, Object> minor = new HashMap<>();
minor.put("name", data.getName());
minor.put("y", data.getData().getMinor());
minor.put("drilldown", data.getName());
HashMap<String, Object> major = new HashMap<>();
major.put("name", data.getName());
major.put("y", data.getData().getMajor());
major.put("drilldown", data.getName());
HashMap<String, Object> critical = new HashMap<>();
critical.put("name", data.getName());
critical.put("y", data.getData().getCritical());
critical.put("drilldown", data.getName());
for (int i = 0; i < data.getDrilldown().size(); i++) {
HIColumn series4 = new HIColumn();
series4.setName(data.getName());
series4.setId(data.getName());
Object[] object2 = new Object[]{data.getDrilldown().get(i).getName(),data.getDrilldown().get(i).getData().getMajor()};
dataDrilldownlAlarms.add(object2);
DrilldownlAlarms.add(series4);
}
dataMinorAlarms.add(minor);
dataMajorAlarms.add(major);
dataCriticalAlarms.add(critical);
}

You need to use real x and y values from the Point class, there is not someting like index property.
You can find a similar example in the highcharts-android wrapper documentation.
