我有列表视图的问题。每次我运行代码时，如果我按下 listview - 程序会因代码而崩溃：
java.lang.IllegalStateException: The content of the adapter has changed but ListView
did not receive a notification. Make sure the content of your adapter is not modified
from a background thread, but only from the UI thread. [in ListView(16908298, class
android.widget.ListView) with Adapter(class android.widget.SimpleAdapter)]
这里的代码片段：
public void getProfileInformation() {
frienders();
System.out.println("STORE" + store);
String fqlQuery = "SELECT status_id, uid , message FROM status WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me())";
Bundle params = new Bundle();
params.putString("q", fqlQuery);
params.putString("access_token", facebook.getAccessToken());
Session session = Session.getActiveSession();
Request request = new Request(session, "/fql", params, HttpMethod.GET, new Request.Callback() {
public void onCompleted(Response response) {
GraphObject graphObject = response.getGraphObject();
System.out.println(response.toString());
if (graphObject != null) {
if (graphObject.getProperty("data") != null) {
try {
String arry = graphObject.getProperty("data").toString();
JSONArray jsonNArray = new JSONArray(arry);
for (int i = 0; i < jsonNArray.length(); i++) {
JSONObject jsonObject = jsonNArray.getJSONObject(i);
String uid = jsonObject.getString("uid");
String status_id = jsonObject.getString("status_id");
String message = jsonObject.getString("message");
Log.i("Entry", "uid: " + uid + ", \nstatus: " + status_id + ", \nmessage: " + message);
final HashMap<String, String> map = new HashMap<String, String>();
name = store.get(uid);
map.put("name", name);
map.put("status_id", status_id);
map.put("message", message);
runOnUiThread(new Runnable() {
@Override
public void run() {
contactList.add(map);
}
});
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
});
Request.executeBatchAsync(request);
System.out.println("aaaa" + contactList);
ListAdapter adapter = new SimpleAdapter(this, contactList, R.layout.list_item, new String[] { "name", "status_id", "message" }, new int[] { R.id.name,
R.id.email, R.id.mobile });
setListAdapter(adapter);
ListView lv = getListView();
lv.requestLayout();
((BaseAdapter) adapter).notifyDataSetChanged();
}
你能给我一些建议吗？谢谢！
