Clicking event of PolyGon in GoogleMap - android

I am trying to make a clickable PolyGon.Even I tried all the method that have already answered in this StackOverFlow. But nothing is worked.
My code is as follows,
JSONObject jsonObj = new JSONObject(result);
final JSONArray jsonArray = jsonObj.getJSONArray("zones");
int i;
System.out.println("PolyGon---> Response jsonArray " + jsonArray);
for (i = 0; i < jsonArray.length(); i++) {
JSONArray jsonArrayPoly = jsonArray.getJSONObject(i).getJSONArray("coordinates");
System.out.println("PolyGon---> Response coordinates " + jsonArrayPoly);
polygonOptions = new PolygonOptions();
polygonOptions.strokeColor(Color.BLACK);
polygonOptions.strokeWidth(2);
polygonOptions.fillColor(getResources().getColor(R.color.zone));
for (int j = 0; j < jsonArrayPoly.length(); j++) {
JSONObject jsonCoordinate = jsonArrayPoly.getJSONObject(j);
System.out.println("PolyGon---> Response lat " + jsonCoordinate.getDouble("lat") + " ----> Long");
polygonOptions.add(new LatLng(jsonCoordinate.getDouble("lat"), jsonCoordinate.getDouble("lng")));
}
googleMap.addPolygon(polygonOptions);
}
polygonOptions.clickable(true);
googleMap.setOnPolygonClickListener(new GoogleMap.OnPolygonClickListener() {
public void onPolygonClick(Polygon polygon) {
Toast.makeText(getApplicationContext(), "Problem reading list of markers.", Toast.LENGTH_LONG).show();
}
});
Your answer is to be more appreciated.

Set your PolygonOptions.clickable before adding your polygon to the map:
polygonOptions.clickable(true);
googleMap.addPolygon(polygonOptions);

"Not a primitive array" error when I try to pull a child from JSON

I'm trying to pull an array from this JSON:
{
\"name\":
{
\"mainName\":\"Ham and cheese sandwich\",
\"alsoKnownAs\":[\"Steamed bao\",\"Pork belly
bun\"]
},
But I get an error, "Not a primitive array", when I write this code:
JSONObject sandwich = new JSONObject(json);
JSONObject name = sandwich.getJSONObject("name");
String mainName = name.getString("mainName");
JSONArray alsoKnownAsArray = new JSONArray(name.getJSONArray("alsoKnownAs"));
for (int i = 0; i < alsoKnownAsArray.length(); i++) {
String alsoKnown = alsoKnownAsArray.getString(i);
Log.v("TAG", alsoKnown);
}
I know there's something wrong with the with the JSONArray code, but don't know what it is. I searched and didn't find out how to get an array when it is a child.
The answer:
JSONArray alsoKnownAsArray = name.getJSONArray("alsoKnownAs");
for (int i = 0; i < alsoKnownAsArray.length(); i++) {
String alsoKnown = alsoKnownAsArray.getString(i);
Log.v("TAG", alsoKnown);
}

Nested JSONArray Record Parsing Issue Android

I am making a App which receives a JSON Data From Server, User will select a value from Spinner like 0,1,2... and so on, On the Basis of number selection JSON will return a data from user defined index like 0,1.. i don't know how to parse a inner JSON Data in Android
json = new JSONObject(JSONParser.Result);
JSONArray jArray = json.getJSONArray("data");
StopElement _stop = new StopElement();
Log.d("JSON Algo Result", json.toString());
if (jArray!=null) {
for (int i = 0; i < jArray.length(); i++) {
jsonarray = jArray.getJSONArray(i);
if (jsonarray != null) {
for (int j = 0; j < jsonarray.length(); i++){
if(i==0) {
jsonarray = jArray.getJSONArray(j);
_stop.setName(jsonarray.getString(0));
StopElement.Stop_name_list.add(_stop.getName());
}
}
} else {
break;
}
}
} else {
return null;

Delete or remove the polylines in google map api v2

I am trying this from quite long so is why i am here seeking for some serious help!!
In my application i am suppose to plot more than 2 alternative routes onclick of a button, say in my application i have 3 buttons such as r1,r2 and r3.When i enter the source and destination locations in my application's respective's edittexts and click enter then i shall be plotting by default r1 so now when i click on r2 button the path/route plotted on the map previously should be erased/deleted and the new alternative path/route should be plotted on the map but isnt happening that way instead of erasing the previous path/route it is plotting both the routes on the map:( can someone please help me?

1- You set the OnClickListener for routeTwo button twice one in the main class and one in the AsyncTask , the one in the AsyncTask should be removed.
2- Pressing the button twice fast would produce your problem, because you will start two separably AsyncTasks each one will draw a route so both routes would be displayed, i prefer using just one AsyncTask as a global variable and before running new one check if there is a running AsyncTask ,this could be done by
if(trafficData != null && trafficData.getStatus() != AsyncTask.Status.FINISHED){
trafficData .cancel(true);

json parsing with listview in android?

Categorylist = new ArrayList<CategoryModel>();
try {
JSONArray jsonArray = new JSONArray(category());
Log.i(CategoryActivity.class.getName(), "Number of entries "
+ jsonArray.length());
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
if (jsonObject == null)
return null;
I try this code, but it gives error
please suggest me a best way to do this

Getting String from Json?

I have a strange problem in my android app. In one method I do this :
try {
String r = responseBody.toString();
JSONArray jArray = new JSONArray(r);
categorys = new String[jArray.length()];
idcategory = new Integer[jArray.length()];
System.out.println("lung " + jArray.length());
for (int i = 0; i < jArray.length(); i++) {
JSONObject jsdata = jArray.getJSONObject(i);
String idcat = jsdata.getString("id_category");
idcategory[i] = Integer.valueOf(idcat);
System.out.println("Id " + idcat);
String namecategory = jsdata.getString("category_name");
categorys[i] = namecategory;
System.out.println("Category name " + namecategory);
}
and everything works fine, I get from server the categorys and category's id. In an other method I do this (for an other response) :
try {
String re = responseBody.toString();
JSONArray jArray = new JSONArray(re);
System.out.println("lung " + jArray.length());
titlephotos = new String[jArray.length()];
photolink=new String[jArray.length()];
for (int i = 0; i < jArray.length(); i++) {
JSONObject jsdata = jArray.getJSONObject(i);
String titlephoto = jsdata.getString("title");
System.out.println("titlu photo " + titlephoto);
titlephotos[i] = titlephoto;
String linkphoto=jsdata.getString("view");
System.out.println("link photo"+ linkphoto);
photolink[i]=linkphoto;
}
}catch(JSONException e) {
System.out.println("You are in catch");
}
and I get only one title photo an after that I get the message from catch(). If I don't put
String linkphoto=jsdata.getString("photo link");
System.out.println("link photo"+ linkphoto);
photolink[i]=linkphoto;
I get all the titles. I don't understand where is the problem,because the methods are similar, and the first one works fine. Can anyone help?
Thanks...
Most likely it is the space in
String linkphoto=jsdata.getString("photo link");
