通过application get set 数据

1.参考application内容public class application extends Application {    private static HashMap<String, Object> HashMap;    public static HashMap<String, Object> getHashMap() {        return HashMap;    }    public static void setHashMap(HashMap<String, Object> hashMap) {        application.HashMap = hashMap;    }    @Override    public void onCreate() {        super.onCreate();      HashMap = new HashMap<>();    }}2.在需要保存数据地方调用如下；  application.setHashMap(objectObjectHashMap);  3.在获取数据地方调用如下；   HashMap<String, Object> hashMap = application.getHashMap();
