Question

我有10个哈希表，我需要将所有这10个哈希表存储到像数组一样的单个实例中。我想将选定的哈希表传递给另一个类/ Activity。我怎样才能做到这一点？谢谢。

创建你的课程：

public class Maps implements Parcelable {
    Map[] mapArray = new Map[10];

    public Map[] getMapArray() {
        return mapArray;
    }

    public void setMapArray(Map[] mapArray) {
        this.mapArray = mapArray;
    }

    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        // TODO Auto-generated method stub

    }

}

然后在活动中做下一件事：

 Intent intent = new Intent(); // create intent that call your another activity
 Maps maps = new Maps(); // create maps object.
 maps.getMapArray();        // mark your selected maps
 intent.putExtra("Maps", maps); // put key for your object
 startActivity(intent);// start your another activity.

在另一项活动中，通过“地图”键获取此对象并使用它。

我解决了我的问题如下

 List<Hashtable<String, String>> info = new ArrayList<Hashtable<String, String>>();

循环

    Hashtable<String, String> hm = new Hashtable<String, String>();
// Put elements to the map

hm.put("Read_Flag", s1);
hm.put("sms_received_id", s2);
hm.put("Sender_Id", s3);
hm.put("Sender_Name", s4);
hm.put("Patient_Name", s5);
hm.put("Received_Date", s6);
hm.put("Received_Text", s7);
hm.put("Received_Text_Full", s8);
hm.put("AttachmentFlag", s9);

// Get a set of the entries
Set<?> set = hm.entrySet();
// Get an iterator
Iterator<?> it = set.iterator();
// Display elements
while(it.hasNext()) {
Map.Entry me = (Map.Entry)it.next();

}
//System.out.println(hm);

info.add(hm);

//循环结束

多个哈希表对象分为单个对象或数组？
