HashMap的使用

1.HashMap循環

HashMap<Integer, Boolean> map = adapter.getChecked();
Iterator iter = map.entrySet().iterator();
while (iter.hasNext()) {
	Map.Entry entry = (Map.Entry) iter.next();
	Boolean val = (Boolean) entry.getValue();
	if (val) {
		int position = (int)entry.getKey();
		String fre = getFreByPosition(position);
		list.add(fre);
	}
}
