I have a fragment, the name is galery. in the fragment galery i'll showing a recycleView that contains name list. but i find an error in this script :
LinearLayoutManager llm = new LinearLayoutManager(this);
and this my full code :
public class galery extends Fragment {
private RecyclerView lvhape;
private RequestQueue requestQueue;
private StringRequest stringRequest;
ArrayList<HashMap<String, String>> list_data;
#Override
public void onCreate(Bundle savedInstanceState) {

}
#Override

View rootView = inflater.inflate(R.layout.fragment_galery, container, false);
String url = "http://bls.hol.es/read.php";
lvhape = (RecyclerView) rootView.findViewById(R.id.lvhape);
LinearLayoutManager llm = new LinearLayoutManager(this);
llm.setOrientation(LinearLayoutManager.VERTICAL);
lvhape.setLayoutManager(llm);
requestQueue = Volley.newRequestQueue(galery.this);
list_data = new ArrayList<HashMap<String, String>>();
stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {

lvhape.setAdapter(adapter);
}
} catch (JSONException e) {

});
requestQueue.add(stringRequest);
return rootView;

}
Try This On Fragment Create Adapter And Model Class And RecyclerView in .xml Class.
public class Event extends Fragment {
RecyclerView recyclerView;
private Event_Adapter event_adapter;
public Event_Model event_model;
public static List<Event_Model> list;
RecyclerView.LayoutManager mLayoutManager;
private static final String FETCH_ID = "id";
private static final String FETCH_NAME = "event_type";
private static final String FETCH_MOBILE = "contact";
private static final String FETCH_DATE = "date";
private static final String FETCH_IMAGE = "uri";
public static final String FETCH_DETAIL = "Your Url";
String type,number,date,uri,id;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v= inflater.inflate(R.layout.fragment_event, container, false);
list = new ArrayList<Event_Model>();
recyclerView = (RecyclerView) v.findViewById(R.id.event_recycler);
mLayoutManager = new LinearLayoutManager(getActivity());
recyclerView.setLayoutManager(mLayoutManager);
fetchdetails();
return v;
}
private void fetchdetails(){
StringRequest jor = new StringRequest(Request.Method.POST, FETCH_DETAIL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
/* Toast.makeText(getActivity(),response,Toast.LENGTH_LONG).show();*/
try {
JSONArray ja = new JSONArray(response);
for (int i = 0; i < ja.length(); i++) {
JSONObject jsonObject = ja.getJSONObject(i);
Integer.parseInt(jsonObject.optString("id").toString());
type = jsonObject.getString(FETCH_NAME);
number = jsonObject.getString(FETCH_MOBILE);
date = jsonObject.getString(FETCH_DATE);
uri = jsonObject.getString(FETCH_IMAGE);
id = jsonObject.getString(FETCH_ID);
event_model = new Event_Model(type,number,date,uri,id);
list.add(event_model);
}
} catch (JSONException e) {
e.printStackTrace();
}
event_adapter= new Event_Adapter(getActivity(), list);
recyclerView.setAdapter(event_adapter);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Volley", "Error");
}
}
);
RetryPolicy retryPolicy=new DefaultRetryPolicy(60000,0,DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
jor.setRetryPolicy(retryPolicy);
VolleySingleton.getInstance(getActivity()).addToRequestQueue(jor);
}
}
I did some changes it works fine in my app try it and if any error occurred mention in comment.

I have a problem I am trying to make (private void Method)work into my Fragment in ( onCreateView ) but it does not work.
As if I put code directly to onCreateView it's work fine without make it into private void().
Example how its not working :
public class classtwst {
public class Status extends Fragment {
private List<List_Data> list;
private RecyclerView rvy;
private MyAdapter adapter;
String id;
private static final String TAG = "Status";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.status, container, false);
Intent i = getActivity().getIntent();
final String id = i.getStringExtra("id");
rvy=(RecyclerView)rootView.findViewById(R.id.recyclerview);
rvy.setHasFixedSize(true);
rvy.setLayoutManager(new LinearLayoutManager(getActivity().getApplicationContext()));
list=new ArrayList<>();
adapter=new MyAdapter(list);
getComment();//--------Here is the problem
return rootView;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
private void getComment(){
final String HI ="http://000000000/Cm.php?id=" + id ;
StringRequest stringRequest=new StringRequest(Request.Method.GET, HI, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject=new JSONObject(response);
JSONArray array=jsonObject.getJSONArray("info");
for (int i=0; i<array.length(); i++ ){
JSONObject ob=array.getJSONObject(i);
List_Data listData=new List_Data(ob.getString("namelast")
,ob.getString("contry"));
list.add(listData);
}
rvy.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
RequestQueue requestQueue = Volley.newRequestQueue(getActivity().getApplicationContext());
requestQueue.add(stringRequest);
}
}
}
How it works:
public class classtwst {
public class Status extends Fragment {
private List<List_Data> list;
private RecyclerView rvy;
private MyAdapter adapter;
String id;
private static final String TAG = "Status";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.status, container, false);
Intent i = getActivity().getIntent();
final String id = i.getStringExtra("id");
rvy=(RecyclerView)rootView.findViewById(R.id.recyclerview);
rvy.setHasFixedSize(true);
rvy.setLayoutManager(new LinearLayoutManager(getActivity().getApplicationContext()));
list=new ArrayList<>();
adapter=new MyAdapter(list);
final String HI ="http://000000000/Cm.php?id=" + id ;
StringRequest stringRequest=new StringRequest(Request.Method.GET, HI, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject=new JSONObject(response);
JSONArray array=jsonObject.getJSONArray("info");
for (int i=0; i<array.length(); i++ ){
JSONObject ob=array.getJSONObject(i);
List_Data listData=new List_Data(ob.getString("namelast")
,ob.getString("contry"));
list.add(listData);
}
rvy.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
RequestQueue requestQueue = Volley.newRequestQueue(getActivity().getApplicationContext());
requestQueue.add(stringRequest);
return rootView;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
}
}
So how I can make it work as private void getComment() ?what is the wrong?
You have to pass id to getComment method to make it work as shown below
in onCreateView:
getComment(id);
and in your method:
private void getComment(String id){
//your code
}
Hope this helps
I am trying to add recyclerview to another recyclerview.
Like Sub Category Recyclerview in its Category RecyclerViews.
problem is that I am getting All categorie's sub category item list in last item of category list.
means
Cat1
cat2
catn(then below this list of subcat1, subcat2....so on)
but it should be like cat1 then in below subcat1 and so on...
here is MainActivity code from where I am calling the api and passing adapter to recyclerview
private void getCategory() {
StringRequest stringRequest = new StringRequest(Request.Method.GET, CategoryUrl, new Response.Listener<String>() {
#Override
public void onResponse(String response) {

JSONObject jsonObject = jsonArray.getJSONObject(i);
catId = jsonObject.getString("ID");
catTitle = jsonObject.getString("TITLE");
Model.setTITLE(catTitle);
Model.setID(catId);
catList.add(Model);
categoryAdaptor.getSubCategory(catId);
}
categoryAdaptor.notifyDataSetChanged();
} catch (JSONException e) {

i have a series of items in recyclerview .i want to set on click listener and open a description page of specific item and set data from json url. i have already made an adapter for description screen and a bean class. i dont know how to set adapter on layout. is it possible to set an adapter on linear layout to show static content from json url?
My code is :
Description activity

response = makeServiceClass.makeServiceConnectionGet(ConstUrl.DESCRP_URLS);
Log.e("response ads", response);
} catch (Exception ex) {
ex.printStackTrace();
}
return response;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(response);
if (Pdialog != null) {
Pdialog.dismiss();
}
if (response != null) {
try {
JSONObject mainObject = new JSONObject(response);

}
Yo are creating the AppShowModule appShowModule111 = new AppShowModule(); Object but you never populated your adaapter with that object. Your JsonObjectRequest onResponse() should look like this;
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONObject("feed").getJSONArray( "entry" );
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject json1 = jsonArray.getJSONObject( i ).getJSONObject("im:name");
AppShowModule appShowModule111 = new AppShowModule();
String name = response.getJSONObject("feed").getJSONArray("entry").getJSONObject(i).getJSONObject("im:name").getString("label").toString();
text.setText(name);
appShowModule111.setAppName((name));
GetDataAdapter1.add(appShowModule111);
}
AppRecyclerViewadapter = new RecyclerViewAdapter(GetDataAdapter1,ListViewActivityFragment.this);
AppRecyclerView.setAdapter(AppRecyclerViewadapter);
} catch (JSONException e) {
e.printStackTrace();

I've a recyclerview adapter with 3 textviews. I used a model class to set texts. Now I want to use the same adapter with different layout and in a different class which only have 1 textview. When I tried, I got NullPointerException (may be becuz the other 2 textviews are blank). Is there any way to use same adapter with different layout and in different class?

You can use the getItemViewType().
Make your adapter(here TimeLineAdapter) extend RecyclerView.Adapter only.
You can change the Adapter's constructer to recieve ItemType and use it in the getItemViewType
Override the int getItemViewType (int position) method in your adapter.
In the onCreateViewHolder you can differentiate between which layout you want to inflate by using the viewType parameter.
In onBindViewHolder use instanceof to check which ViewHolder was created and call the related bind functions
A Sample Code-
// Adapter class
public class TimeLineAdapter extends RecyclerView.Adapter{
.....
int type;
public TimeLineAdapter(Context mContext, int resource, List<TimeLineModel> feedList,int layoutType) {
.....
.....
type=layoutType;
}
#Override
public int getItemViewType(int position) {
return type;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if(viewType==1){
View view = View.inflate(parent.getContext(), resource, null);
return new TimeLineViewHolder(view, viewType);
}else{
View view = View.inflate(parent.getContext(), resource, null);
return new TimeLineViewHolder2(view, viewType);
}
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if(holder instanceof TimeLineViewHolder){
TimeLineModel timeLineModel = mFeedList.get(position);
((TimeLineViewHolder) holder).servicename.setText(timeLineModel.getServname());
......
}
else if(holder instanceof TimeLineViewHolder2){
....
....
}
}
#Override
public int getItemCount() {
return (mFeedList!=null? mFeedList.size():0);
}
}
