标签： android

根据项目点击的次数我有100个项目的网格我想要将项目重新排列到第一个位置哪个项目的点击次数按降序排列更高

HashMap<String, Integer> map = new HashMap<String, Integer>();
ValueComparator bvc = new ValueComparator(map);
TreeMap<String, Integer> sorted_map = new TreeMap<String, Integer>(bvc);

map.put("Windows", sharedPref.getInt("Windows", 0));
map.put("iOS", sharedPref.getInt("iOS", 0));
map.put("Android", sharedPref.getInt("Android", 0));
map.put("Blackberry", sharedPref.getInt("Blackberry", 0));
map.put("Java", sharedPref.getInt("Java", 0));
map.put("JQuery", sharedPref.getInt("JQuery", 0));
map.put("Phonegap", sharedPref.getInt("Phonegap", 0));
map.put("SQLite", sharedPref.getInt("SQLite", 0));
map.put("Thread", sharedPref.getInt("Thread", 0));
map.put("Video", sharedPref.getInt("Video", 0));
sorted_map.putAll(map);

iconList = new ArrayList<Integer>();
Map<String, Integer> treeMap = new TreeMap<String, Integer>(sorted_map);

for (Map.Entry<String, Integer> entry : treeMap.entrySet()) {
System.out.println("Key : " + entry.getKey() 
                                  + " Value : " + entry.getValue());


sortedList.add(entry.getKey());

}
