如何遍历HashMap的所有内容？我只得到最后一次

   ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();

// 0
    HashMap<String, String> map = new HashMap<String, String>();
    map.put("name", "name0");
    map.put("company", "company0");
    list.add(map);
// 1
    map = new HashMap<String, String>();
    map.put("name", "name1");
    map.put("company", "company1");
    list.add(map);


    for (String key : map.keySet()) {
        String value = map.get(key);
        Log.w("dd:", "Key = " + key + ", Value = " + value);
    }

我只是最后一次投放：

Key = company, Value = company1
Key = name, Value = name1

Answer 1

列表中有多个地图。您需要遍历列表，然后遍历列表中的地图。

for(HashMap<String, String> curMap : list) {
    //Put your loop over the map here.
}

Answer 2

首先迭代列表，然后遍历地图。

for(Map<String, String> myMap: list){
    for (Map.Entry<String, String> entry : myMap.entrySet()){
           Log.w("dd:", "Key = " + entry.getKey() + ", Value = " +             
              entry.getValue());
          }
}
