How to sort the vectors of custom objects and select the attributes to sort?
I do see this question & answer, but I'm not sure what its ranking is based on Code examples will take precedence over methodology
Sort a Vector of custom objects
public class ItemLocation { String icon; String title; String message; String subtext; String deviceid; double latCoords; double lngCoords; int expiary; int id; double proximity; String locSeen; }
Solution
The following is an example that allows you to sort by the specified field of itemlocation:
public void sort(final String field,List<ItemLocation> itemLocationList) { Collections.sort(itemLocationList,new Comparator<ItemLocation>() { @Override public int compare(ItemLocation o1,ItemLocation o2) { if(field.equals("icon")) { return o1.icon.compareTo(o2.icon); } if(field.equals("title")) { return o1.title.compareTo(o2.title); } else if(field.equals("message")) { return o1.message.compareTo(o2.message); } . . fill in the rest of the fields... . else if(field.equals("locSeen")) { return o1.locSeen.compareTo(o2.locSeen); } } }); }
