See this issue it seems that your list has some null values
https://github.com/bignerdranch/expandable-recycler-view/issues/321
I ran your code and logged your list you have null values in a list
check this method
#Override
public List<Alloted_kids> getChildList() {
return null;
}
this method should return non null value this method only causing problem
use return Collections.emptyList(); instead of return null there

Use Retrofit to display JsonObject information in Recylerview?

I tried to display jsonObject in Recyclerview use retrofit library, but it only accept in the Array format. I tried to change the jsonObject to jsonArray, but the problem is the server don't recognize the json type. So now my question is, how to display jsonObject to recyclerview widget. Give me tips or idea..Thank in advance
This is my Jsonobject Data..
{
"success": true,
"data": {
"id": 1,
"parent_id": null,
"name": "Ionnex Sdn Bhd",
"description": "Test Value",

});
}
AFTER FEW MONTH, I SOLVED THE PROBLEM..
Use retrofit library and call the api before display. So here how to call the data for future reference....
public void getOneOrg(String orgId, final GetOneOrgCallback apiCallback) {
String auth = "Bearer " + LocalData.getInstance().loadStringData(LocalData.SP_KEY_ACCESS_TOKEN);
Call<JsonObject> call = apiService.getOneOrg(auth, orgId);
call.enqueue(new Callback<JsonObject>() {
#Override
public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
StaticFunction.showLogD("getOneOrg: " + response.body().toString());
Boolean isSuccess = response.body().get("success").getAsBoolean();
if (isSuccess) {
JsonObject jsonData = response.body().get("data").getAsJsonObject();
Organization org = gson.fromJson(jsonData, Organization.class);
apiCallback.getOneOrgSuccess(org);
} else {
apiCallback.getOneOrgFail("Data error");
}
}
#Override
public void onFailure(Call<JsonObject> call, Throwable throwable) {
apiCallback.getOneOrgFail("Data error");
}
});
}
Here how i called the json object in API "Organization" is the java file for each variables in api.

Android Recycler View caching

I'm using volley to load data using JSON Parsing in to a recycler view. I've used recylcer view before, but somehow, the downloaded data is persistent this time, meaning its still there after the app is closed, maybe stays in cache. I'm not sure, what I'm doing wrong here. Any help is appreciated, thanks.
Edit: The application is storing downloaded data after the app is closed, which doesn't happen when using recycler view.

Firstly, your not clearly stated.
If you are using web service, then you should send the items by coupling them in web service.
Like in JSON
{
video[{"name":"abc","image_url":"kvndskk"}{"name":"abc","image_url":"kvndskk"}{"name":"abc","image_url":"kvndskk"}{"name":"abc","image_url":"kvndskk"}
]
}
here you see you receiving in couple
