Question

list<map<string，object>>怎么转换为list

Answer 1

list<map<string，object>>怎么转换为list
map.values怎么转换为list或者string[]
if (areas != null)
for (Area eachArea : areas) {
areaNames1.put(eachArea.getId(),eachArea.getName());
}

ArrayAdapter<String> areaAdapter = new ArrayAdapter<String>(context,
android.R.layout.simple_spinner_item, ****);

（String[]）areaNames1.values().toArray()我用的这个不行呀
谁能帮我ko啊。

　　Map<String, String> map = new HashMap<String, String>();
map.put("1", "1");
map.put("2", "2");
map.put("3", "3");
map.put("4", "4");

Collection<String> valueCollection = map.values();
final int size = valueCollection.size();

List<String> valueList = new ArrayList<String>(valueCollection);

String[] valueArray = new String[size];
map.values().toArray(valueArray);
