android：从ArrayList中获取键值对

直接上示例：

public void getList(String cmdStr, int index, int type, ArrayList> mList) {

try {

JSONArray gethotlist = new JSONObject(cmdStr).getJSONArray("list");

JSONObject jso = (JSONObject)gethotlist.opt(index);

JSONArray jContent = jso.getJSONArray("content");

for (int j = 0; j < jContent.length(); j++) {

JSONObject mJContent = (JSONObject)jContent.opt(j);

HashMap map = new HashMap();

switch(type) {

case 0:

map.put("ItemTitle", getSecList(mJContent).name);

System.out.println("name:"+getSecList(mJContent).name);

break;

case 1:

map.put("ItemUrl", getSecList(mJContent).url);

map.put("ItemTitle", getSecList(mJContent).name);

System.out.println("url:"+getSecList(mJContent).url);

System.out.println("name:"+getSecList(mJContent).name);

break;

case 2:

map.put("ItemLen", getSecList(mJContent).len);

System.out.println("len:"+getSecList(mJContent).len);

break;

default:

break;

}

mList.add(map);

}

} catch (JSONException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

private void test() {

mDqJson.getList(cmdStr, index, GET_URL, urlList);

if (!urlList.isEmpty()) {

Iterator> it = urlList.iterator();

HashMap hash;

Object value = new Object();

Object nameValue = new Object();

int i = 0;

while(it.hasNext()) {

hash = it.next();

HashMap map = new HashMap();

value = hash.get("ItemUrl");

nameValue = hash.get("ItemTitle");

System.out.println("value-url:"+value.toString());

System.out.println("value-name:"+nameValue.toString());

}

}

}
