android怎么取出list里面特定的数据
只需要循环一下，判断即可。
示例代码：
1.遍历整个list集合
for(int i=0; ilist.size(); i++){
}
2.在for循环中增加判断代码
if(list.get(i).equals("指定")）｛｝
3.得到每一个item进行判断即可。
android怎么传一个list集合
方法1： 直接让User类继承Serializable或者Parcelable接口即可，Intent只可以传输序列化的对象pre t="code" l="java"//User类
public class User implements Serializable{
private String name;
.
}
//直接加入intent
ListUser list = new ArrayListUser();
Intent intent = new Intent();
intent.putExtra("list",list);
方法2： 把list集合转为字符串表示，可以使用json格式，直接用Gson框架转换即可，再到另一个activity转换回来pre t="code" l="java"ListUser list = new ArrayListUser();
Type type = new TypeTokenArrayListUser()(){}.getType();
String json = new Gson().toJson(list,type);
intent.putExtra("list",json);
//转换回ListUser
String json = getIntent.getStringExtra("list");
Type type = new TypeTokenArrayListUser()(){}.getType();
ListUser list = new Gson().fromJson(json,type);
