我得到json数据并将其放入hashmap和hashmap中,并放入一个数组列表中。延长ListFragment显示来自Arraylist of Hashmap的数据
protected String doInBackground(String... urls) {
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("full_name", etUserSearch.getText().toString());
responseReceive = JsonPostClient.SendHttpPost(urls[0],
jsonObject);
} catch (JSONException e) {
e.printStackTrace();
}
try {
Success = responseReceive.getJSONArray("Success");
for (int i = 0; i < Success.length(); i++) {
JSONObject c = Success.getJSONObject(i);
String full_name = c.getString(TAG_FULL_NAME);
String user_name = c.getString(TAG_USER_NAME);
String user_id = c.getString(TAG_USER_ID);
HashMap<String, String> friends = new HashMap<String, String>();
// adding each child node to HashMap key => value
friends.put(TAG_FULL_NAME, full_name);
friends.put(TAG_USER_NAME, user_name);
friends.put(TAG_USER_ID, user_id);
// adding contact to contact list
FriendSearchList.add(friends);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
Log.d("hello", "");
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (pDialog.isShowing())
pDialog.dismiss();
printFriends();
};
我检查这些数据是printFriends所有有效的是发生在片段()方法,并想只显示“TAG_FULL_NAME”在ListView数据。在ListView的检查数据和装载
public void printFriends() {
int len = FriendSearchList.size();
for (int i = 0; i < len; i++) {
String f_name = FriendSearchList.get(i).get(TAG_FULL_NAME);
String u_name = FriendSearchList.get(i).get(TAG_USER_NAME);
String u_id = FriendSearchList.get(i).get(TAG_USER_ID);
Log.d("full_name", f_name);
Log.d("user_name", u_name);
Log.d("user_id", u_id);
}
ListAdapter adapter = new SimpleAdapter(getActivity(),
FriendSearchList, R.layout.tab_addfriend_list,
new String[] { TAG_FULL_NAME }, new int[] { R.id.full_name });
setListAdapter(adapter);
}
tab_add_friends XML布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>

</LinearLayout>
我的ListView控件初始化
View rootView = inflater.inflate(R.layout.tab_add_friends, container,
false);
lv = (ListView) rootView.findViewById(R.id.listView);
方法没有显示没有显示到列表视图中的错误。需要建议或线索摆脱这个问题。
看看这个:http://stackoverflow.com/questions/25375831/customarrayadapter-implementationunable-to-get-the-resource-id/25376257#25376257并使用HashMap的,而不是用户类。 – 2014-09-04 05:36:53
为什么不使用自定义适配器?或者创建MyUser类并覆盖toString()方法,只需放入“TAG_FULL_NAME”并将此类添加到arraylist – thegiga 2014-09-04 05:44:46
@GiGa thnx以获得建议。我认为它应该工作,但我也尝试其他方式 – 2014-09-04 05:52:17
