Android: ListView排序 对listdata排序

private List<Map<String, Object>> getData() {  
  
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();  
  
//add Data ...  
  
//对list进行排序  
  
if (!list.isEmpty()) {      
  
     Collections.sort(list, new Comparator<Map<String, Object>>() {  
  
      @Override  
  
      public int compare(Map<String, Object> object1,  
  
      Map<String, Object> object2) {  
  
  //根据文本排序  
  
           return ((String) object1.get("text_content")).compareTo((String) object2.get("text_content"));  
  
      }      
  
     });      
  
}  
  
return list;  
  
}
