ArcGISLayerInfo[] layers = c.getMap().getLayers(); // It gives me my tiledmap.
for (int i = 0; i < layers.length; i++) {
List<Legend> _legend = layers.getLegend();
Log.v("Legend :", _legend.get(0).getLabel());
}
But this code is not working so i wrote codes for reading legends these codes.
private class LegandBul extends
AsyncTask<String, Void, ArrayList<ArrayList<legendClass>>> {
String url;
// contacts JSONArray
ArrayList<legendClass> legendA;
ArrayList<ArrayList<legendClass>> layersA;
@Override
protected void onPreExecute() {
super.onPreExecute();
// Showing progress dialog
legendA = new ArrayList<legendClass>();
layersA = new ArrayList<ArrayList<legendClass>>();
}
@Override
protected ArrayList<ArrayList<legendClass>> doInBackground(
String... query) {
// Creating service handler class instance
url = query[0];
ServiceHandler sh = new ServiceHandler();
// String json = new
// GsonBuilder().create().toJson(anaEkraninstance.creds,
// UserCredentials.class);
// Making a request to url and getting response
String jsonStr = sh.makeServiceCall(url, ServiceHandler.GET);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
JSONArray layers = jsonObj.getJSONArray("layers");
// looping through All Contacts
for (int i = 0; i < layers.length(); i++) {
JSONObject c = layers.getJSONObject(i);
JSONArray legend = c.getJSONArray("legend");
for (int j = 0; j < legend.length(); j++) {
JSONObject legendic = legend.getJSONObject(j);
String label;
if (legendic.getString("label").isEmpty()) {
label = c.getString("layerName");
} else {
label = legendic.getString("label");
}
String imageData = legendic.getString("imageData");
legendClass newLegend = new legendClass(label,
StringToBitMap(imageData));
legendA.add(newLegend);
}
}
layersA.add(legendA);
return layersA;
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
return null;
}
@Override
protected void onPostExecute(ArrayList<ArrayList<legendClass>> result) {
super.onPostExecute(result);
for (int i = 0; i < layersA.size(); i++) {
for (int j = 0; j < layersA.get(i).size(); j++) {
resultLegend.add(layersA.get(i).get(j));
}
}
legendAdapter.setItemList(resultLegend);
legendAdapter.notifyDataSetChanged();
/**
* Updating parsed JSON data into ListView

}
}
I can read legends with these codes. it run correctly and show me legends of tiledmap.But if my map has control for login, it needs to password or username like usercredentials so how can i implement this asynctask running with usercredentials.
Also i don't want to learn that for only getting legends list. For example. When i edit feature layer and if attribute has a domain, esri android sdk sample codes not getting codedvalues so i wrote code for it and if attribute has a domain i get codedvalue with asynctask so again i must use asynctask with usercredentials. I hope you understand, my english is not good, i am sorry about that. If you have sample code about Async Task with UserCreditials, Can you share with me ?
