我正在做一个项目，我从远程数据库加载一些数据并将它们显示在ListView. 数据已正确加载，但问题是在Listview( SimpleAdapter) 中显示它们。类扩展ListActivity。
代码：
protected void onPostExecute(String file_url){
progressDialog.dismiss();
try{
if(jsonObject.getInt("success") == 1){
jsonArray = jsonObject.getJSONArray("notes");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject o = jsonArray.getJSONObject(i);
Note tempNote = new Note(o.getInt("note_id"), o.getString("description"), o.getString("data"));
userData.addNote(tempNote);
HashMap<String, String> hashMap = new HashMap<String, String>();
hashMap.put("id", o.getString("note_id"));
hashMap.put("description", o.getString("description"));
userNotes.add(hashMap);
Log.d(TAG, userNotes.get(0).toString());
}
}
Toast.makeText(UserNotes.this, jsonObject.getString("message"), Toast.LENGTH_LONG).show();
}
catch (JSONException e){
e.printStackTrace();
}
runOnUiThread(new Runnable(){
@Override
public void run() {
ListAdapter listAdapter = new SimpleAdapter(UserNotes.this,
userNotes,
R.layout.list_note,
new String[] {"id, description"},
new int[] {R.id.list_note_id, R.id.list_note_description});
setListAdapter(listAdapter);
}
});
}
