java.lang.Integer cannot be cast to java.lang.Double

Question

i am getting a weird error in which android is not allowing me assign an item from a ArrayList because it detects it as integer this happens only when the item at the position is a whole number like 12 instead of 12.0

My code

public class CategoryAdapter extends BaseAdapter {
private final Context context;
private ArrayList<Category> categories ;
private final ArrayList<Double> items;

public CategoryAdapter(Context context, ArrayList<Double> i) {
    this.context = context;
    categories = Category.getActiveCategories();
    if(i.size()==0)
    {
        Double [] ar = new Double[]{0.0,0.0,0.0,0.0};
        items = new ArrayList<Double>(Arrays.asList(ar));
    }
    else
    {
        items = i;
    }
}

@Override
public int getCount() {
    return items.size();
}

@Override
public Double getItem(int position) {
    return items.get(position);
}

@Override
public long getItemId(int position) {
    // TODO implement own logic with ID
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView;
    if (convertView == null) {
        rowView = inflater.inflate(R.layout.item_ais_category_list, parent, false);
    }
    else {
        rowView = convertView;
    }

    TextView category = (TextView) rowView.findViewById(R.id.tv_ais_category_item);
    TextView tvThreatLevel = (TextView) rowView.findViewById(R.id.tv_ais_threat_level_item);
    View circle = rowView.findViewById(R.id.v_ais_circle);

    category.setText(categories.get(position).name);
    double threatlevel = 0;
    try {
        threatlevel = (double) items.get(position);
    }
    catch (Exception e)
    {
        e.printStackTrace();
        Log.d("array",items.toString());
        Log.d("count",Integer.toString(position));
    }
    if(threatlevel<=10d) {
        tvThreatLevel.setText("Safe");
        tvThreatLevel.setTextColor(context.getResources().getColor(R.color.alert_low));
    }
    else if(threatlevel>10d&&threatlevel<=20d) {
        tvThreatLevel.setText("Low");
        tvThreatLevel.setTextColor(context.getResources().getColor(R.color.alert_low));
    }
    else if(threatlevel >20d &&threatlevel<=40d)
    {
        tvThreatLevel.setText("Medium");
        tvThreatLevel.setTextColor(context.getResources().getColor(R.color.alert_med));
    }
    else
    {
        tvThreatLevel.setText("High");
        tvThreatLevel.setTextColor(context.getResources().getColor(R.color.alert_high));
    }
    GradientDrawable bg = (GradientDrawable)circle.getBackground();
    int color = Color.parseColor(categories.get(position).color);
    bg.setColor(color);
    return rowView;
}
}

and this is the stack trace of the error

For example if the array is

[251.03, 1086.97, 891.53, 615]

the error occurs at position 3

am i doing something wrong or is there any work around through this Thanks in advance

Well if the list is declared as ArrayList<Double> why are you trying to put integers into it? Java won't allow a list with mixed types like that. The only way I can think to do that would be to add the items as Object and then use instanceof to cast them when accessing them from the list. Another option would be to convert any integers to double. Is that what you're asking? — NoChinDeluxe, Jun 17 at 19:39
Would ArrayList<Number> work for you? Also, which line is the error coming from? — 4castle, Jun 17 at 19:42
I am fetching that data from a parse and the guys working on that have the data like that and parse dosent even allow to just an extra zero after decimal . and it is declared as that coz the fetched data is of type arraylist<Double> — B0rn2C0de, Jun 17 at 19:44
@4castle i will try that and the error is on line. threatlevel = (double) items.get(position); — B0rn2C0de, Jun 17 at 19:45

the error is on line. threatlevel = (double) items.get(position);

The issue seems to be that it doesn't want to cast and autobox at the same time. Since both Double and Integer extend Number, you can use:

threatlevel = items.get(position).doubleValue();
