如何使哈希表Arraylist达到其他目的？

创建一个延伸的类

Serializable

getter

setter

List<Hashtable<String, String>>list

Custom.java

public class Custom implements Serializable{    private static final long serialVersionUID = 4466821913603037341L;    private List<Hashtable<String, String>> list;    public List<Hashtable<String, String>> getList() {        return list;    }    public void setList(List<Hashtable<String, String>> list) {        this.list = list;    }}

传递到下一个活动。

List<Hashtable<String, String>> list = new ArrayList<Hashtable<String,String>>();Custom custom = new Custom();custom.setList(list);intent.putExtra("myobj", custom);

在下一个活动中检索

Intent intent = getIntent();Custom custom = (Custom) intent.getSerializableExtra("myobj");List<Hashtable<String, String>> list = custom.getList();
