重点:在使用Map时注意key-value,key用于检索value的内容. 在正常情况下,可以不允许重复:在java中分为2中情况,一是内存地址重复,另一个是不同的地址但内容相等. 在使用Map是一定要特别注意,是否允许键值相等存储,在使用IdentityHashMap的键是变量时要小心. 在下面的示例中,键值为常量,指向同一个内存地址,所以会经过修改后还是保持相同数量的元素. import java.util.IdentityHashMap; import java.util.Map; pu…

原因: SharedPreferences没有保存数组的方法,但是有时候为了保存一个数组而进行序列化,或者动用sqlite都是有点杀猪焉用牛刀的感觉,所以就自己动手改进一下吧. 解决方案: 采用的方式是先转换成JSON,然后保存字符串,取出的时候再讲JSON转换成数组就好了. public void saveInfo(Context context, String key, List<map<string, string="">> datas) { JSONAr…
