Android 遍历Hashmap里面的key 和value

Android项目中需要将很多数据显示在一个listview上面，所以想到了使用hashmap的泛型来保存数据：

  HashMap<String, Object> listItem = new HashMap<String,Object>；</span>

这时候需要先存入数据，然后要提取出来赋值给textview，以下是遍历key-value方法：

for (int i = 0; i < summaryMap.size(); i++) {listItem = new HashMap<String, Object>();Iterator<Entry<String, SummaryStruct>> iter = summaryMap.entrySet().iterator();while (iter.hasNext()) {listItem = new HashMap<String, Object>();@SuppressWarnings("rawtypes")Map.Entry entry = (Map.Entry) iter.next();// String instrument = (String) entry.getKey();SummaryStruct sumStru = (SummaryStruct) entry.getValue();</span>listItem.put("instrument", sumStru.getInstrument());listItem.put("netLots", sumStru.getNetLots());listItem.put("netFloatPL", sumStru.getNetFloatPL());listItem.put("isNetBuysell", sumStru.isNetBuysell());listItem.put("sellLots", sumStru.getSellLots());listItem.put("bidPrice", sumStru.getBidPrice());listItem.put("sellFloatPL", sumStru.getSellFloatPL());listItem.put("buyLots", sumStru.getBuyLots());listItem.put("askPrice", sumStru.getAskPrice());listItem.put("buyFloatPL", sumStru.getBuyFloatPL());maps.add(listItem);}
