Sorting YouTube data with JSON in RecyclerView

I am working with YouTube Data API and fetching data using JSON Retrofit in RecyclerView. The data consists of list of videos from a channel which also includes live videos.
The URL for the channel is:
https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCJekW1Vj5fCVEGdye_mBN6Q&maxResults=50&order=date&key=[YOUR_API_KEY] .
I am trying to sort the data in RecyclerView in such a way that the live videos comes at the top of list and rest of the videos are sorted according to the date. The adapter for RecyclerView is as follows:
public class AdapterHome extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private Context context;
private List<VideoYT> videoList;
public
AdapterHome(Context context, List<VideoYT> videoList) {
this.context = context;
this.videoList = videoList;
}
class YoutubeHolder extends RecyclerView.ViewHolder {
ImageView thumbnail;
TextView judul, tanggal;
public YoutubeHolder(#NonNull View itemView) {
super(itemView);
thumbnail = itemView.findViewById(R.id.iv_thumbnail);
judul = itemView.findViewById(R.id.tv_judul);
tanggal = itemView.findViewById(R.id.tv_tglUpdate);
}
public void setData(final VideoYT data) {
final String getJudul = data.getSnippet().getTitle();
String getTgl = data.getSnippet().getPublishedAt();
String getThumb = data.getSnippet().getThumbnails().getMedium().getUrl();
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(context, YTPlayerActivity.class);
i.putExtra("video_id", data.getId().getVideoId());
i.putExtra("video_title", getJudul);
context.startActivity(i);
}
});
judul.setText(getJudul);
tanggal.setText(getTgl);
Picasso.get()
.load(getThumb)
// .placeholder(R.mipmap.ic_gujrati)
.fit()
.centerCrop()
.into(thumbnail, new Callback() {
#Override
public void onSuccess() {
Log.d(TAG, "Thumbnail berhasil ditampilkan");
}
#Override
public void onError(Exception e) {
Log.e(TAG, "Thumbnail error: ", e);
}
});
}
}
#NonNull
#Override
public RecyclerView.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.row_item_home, parent, false);
return new YoutubeHolder(view);
}
#Override
public void onBindViewHolder(#NonNull RecyclerView.ViewHolder holder, int position) {
VideoYT videoYT = videoList.get(position);
YoutubeHolder yth = (YoutubeHolder) holder;
yth.setData(videoYT);
}
#Override
public int getItemCount() {
return videoList.size();
}
}
The default sorting order doesn't provide any option for this. Can somebody guide me is it possible or not?
The JSON data format for this search is as follows:

Your issue boils down to having a custom comparator for the VideoYT class (defined, for example, within the class AdapterHome itself):
public static Comparator<VideoYT> myComparator =
new Comparator<VideoYT>() {
#Override
public int compare(VideoYT a, VideoYT b) {
boolean aLive = a.getSnippet().getLiveBroadcastContent() == "live";
boolean bLive = b.getSnippet().getLiveBroadcastContent() == "live";
if (aLive == bLive)
return b.getSnippet().getPublishedAt().compareTo(
a.getSnippet().getPublishedAt());
else
return aLive ? -1 : +1;
}
};
Then using this comparator for sorting videoList in the constructor of AdapterHome:
public
AdapterHome(Context context, List<VideoYT> videoList) {
this.context = context;
Collections.sort(videoList, myComparator);
this.videoList = videoList;
}
Depending on a wider context of your program (which your sample code above doesn't show), you may also need (want?) to have videoList not modified within that constructor. Then, instead of sorting the videoList itself, make a copy of it and sort that copy:
public
AdapterHome(Context context, List<VideoYT> videoList) {
this.context = context;
this.videoList = new ArrayList<>(videoList);
Collections.sort(this.videoList, myComparator);
}

set data into recyclerview using gson in android

I'm trying to set recyclerview data from this type of json response but data is not setting into recylerview
Response:
{
"vehicles": [
{
"id": 1,
"vehicle_number": "gj03fn3235",
"driver_id": 4,
"vehicle_type": "3",
"admindata": {
"id": 7,
"email": "chirag.pwt2#gmail.com"
},
"userdata": {
"id": 4,
"email": "keval.pwt#gmail.com"
}
},
{
"id": 2,
"vehicle_number": "gj03fn3236",
"driver_id": 4,
"vehicle_type": "4",
"admindata": {
"id": 7,
"email": "keval.pwt#gmail.com"
},
"userdata": {
"id": 4,
"email": "keval.pwt#gmail.com"
}
}
]
}
I have created a pojo class of response But my data is not setting into recylerview api call successfully but response print in logcat i tried to set vehicle_number and email in recylerview
Here is my java code:
#Override
public void onSuccess(int
statusCode, Header[] headers, JSONObject
response) {
super.onSuccess(statusCode,
headers, response);
try {
Gson gson = new
GsonBuilder().create();
List<VehicleList> list =
gson.fromJson(response.getJSONArray
("vehicles").toString(), new
TypeToken<List<VehicleList>>() {
}.getType());
Log.e("listsize",""+list.size());
if (list.size() == 0) {
txt_error.setVisibility(View.VISIBLE);
} else {
VehiclesDriverAdpter
acceptedRequestAdapter = new
VehiclesDriverAdpter(list);
recyclerView.setAdapter
(acceptedRequestAdapter);
acceptedRequestAdapter.
notifyDataSetChanged();
}
} catch (JSONException e) {
}
}
My Adapter class:
public class VehiclesDriverAdpter extends
RecyclerView.Adapter<VehiclesDriverAdpter.Holder> {
List<VehicleList> list;
List<Vehicle> list1;
FragmentActivity activity;
public VehiclesDriverAdpter(List<VehicleList> list) {
this.list = list;
}
#Override
public Holder onCreateViewHolder(ViewGroup parent, int viewType) {
return new
Holder(LayoutInflater.from(parent.getContext())
.inflate(R.layout.adapter_vehicle, parent, false));
}
#Override
public void onBindViewHolder(final Holder holder, int position) {
final Vehicle pojo1 = list1.get(position);
Log.e("VehicleNumber",""+pojo1.getVehicleNumber());
holder.txt_vehicle_number.setText(pojo1.getVehicleNumber());
holder.txt_vehicle_driver_name.setText(pojo1.getUserdata().getEmail());
holder.drivername.setText(pojo.getDriver_name());
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Bundle bundle = new Bundle();
bundle.putSerializable("data", pojo1);
VehiclesInfoFragment detailFragment = new
VehiclesInfoFragment();
detailFragment.setArguments(bundle);
((HomeActivity) holder.itemView.getContext()).
changeFragment(detailFragment, "Passenger Information");
}
});
BookFont(holder, holder.txt_vehilce_type);
BookFont(holder, holder.txt_vehicle_driver_name);
BookFont(holder, holder.txt_vehicle_driver_mobile_no);
MediumFont(holder, holder.txt_vehicle_number);
}
#Override
public int getItemCount() {
return list.size();
}
public class Holder extends RecyclerView.ViewHolder {
TextView txt_vehicle_number, txt_vehilce_type, txt_vehicle_driver_name,
txt_vehicle_driver_mobile_no;
CircleImageView img_driver;
public Holder(View itemView) {
super(itemView);
txt_vehicle_number = (TextView)
itemView.findViewById(R.id.txt_vehicle_number);
txt_vehilce_type = (TextView)
itemView.findViewById(R.id.txt_vehilce_type);
txt_vehicle_driver_name = (TextView)
itemView.findViewById(R.id.txt_vehicle_driver_name);
txt_vehicle_driver_mobile_no = (TextView)
itemView.findViewById(R.id.txt_vehicle_driver_mobile_no);
}
}
public void BookFont(Holder holder, TextView view1) {
Typeface font1 =
Typeface.createFromAsset(holder.itemView.getContext().getAssets(),
"font/AvenirLTStd_Book.otf");
view1.setTypeface(font1);
}
public void MediumFont(Holder holder, TextView view) {
Typeface font =
Typeface.createFromAsset(holder.itemView.getContext().getAssets(),
"font/AvenirLTStd_Medium.otf");
view.setTypeface(font);
}
}

Try this one
YourActivity.this.runOnUiThread(new Runnable() {
public void run() {
setRecyclerData();
}
});
private void setRecyclerData(){
VehiclesDriverAdpter acceptedRequestAdapter = new VehiclesDriverAdpter(list);
recyclerView.setAdapter(acceptedRequestAdapter);
acceptedRequestAdapter.notifyDataSetChanged();
}

I think you have forgotten to add layout manager on your recyclerView add it in code like this
LinearLayoutManager mLayoutManager = new LinearLayoutManager(getBaseContext());
recyclerView.setLayoutManager(mLayoutManager);
VehiclesDriverAdpter acceptedRequestAdapter = new VehiclesDriverAdpter(list);
recyclerView.setAdapter (acceptedRequestAdapter);

You put data to List<VehicleList> list list, but take it from List<Vehicle> list1;
You can try(but only if you always have one item in VehicleList) something like this
public VehiclesDriverAdpter(List<VehicleList> list) {
if(!list.isEmpty()){
this.list1 = list.get(0);
}
}

How to parse json on tablayout

Okay , I have an Json I want to parse it to the tabs (if i have 6 string so it means 6 tabs) i'm receiving the data but I can't parse it..
anyone can help ???
public class WallpaperPageActivity extends BaseActivity {
private ViewPager mViewPager;
private TabLayout mTabLayout;
private WallpaperActivityFragmentAdapter wallpaperActivityFragmentAdapter;
private CategoryList resultCategories;
private ArrayList<Category> categoriesTab = new ArrayList<>();
protected ApiInterface service;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_wallpaper);
service = RestApiClient.getClient();
mViewPager = (ViewPager) findViewById(R.id.activity_wallpapers_content_viewpager);
mTabLayout = (TabLayout) findViewById(R.id.activity_wallpapers_content_tablayout);
getCategoryNames();
mViewPager.setAdapter(new WallpaperActivityFragmentAdapter(getSupportFragmentManager(), this, categoriesTab));
mViewPager.getAdapter().notifyDataSetChanged();
setTablayoutItemsMode(mTabLayout, categoriesTab);
mTabLayout.setupWithViewPager(mViewPager);
setupTabLayout(mTabLayout, categoriesTab);
}
public void getCategoryNames() {
Call<CategoryList> call = service.requestCategoryList("get_categories_wallpaper");
call.enqueue(new Callback<CategoryList>() {
#Override
public void onResponse(Response<CategoryList> response) {
Log.d("wow", "Status Code = " + response.code());
if (response.isSuccess()) {
// request successful (status code 200, 201)
resultCategories = response.body();
for (int i = 0; i < resultCategories.getCategories().size(); i++) {
categoriesTab.add(resultCategories.getCategories().get(i));
}
} else {
Log.d("wow", "error = ");
}
}
#Override
public void onFailure(Throwable t) {
}
});
}
public void setTablayoutItemsMode(TabLayout tabLayout, List<Category> categories) {
if (categories.size() > 3)
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
else {
tabLayout.setTabMode(TabLayout.MODE_FIXED);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
}
}
}
this is the fragment adapter.
public class WallpaperActivityFragmentAdapter extends FragmentPagerAdapter {
private int PAGE_COUNT = 1;
private ArrayList<Category> categoriesTab;
private Context context;
private Bundle bundle;
private WallpaperActivityFragment fragment;
public WallpaperActivityFragmentAdapter(FragmentManager fm, Context context, ArrayList<Category> categoriesTab) {
super(fm);
this.context = context;
this.categoriesTab = categoriesTab;
PAGE_COUNT = categoriesTab.size();
}
#Override
public int getCount() {
return PAGE_COUNT;
}
#Override
public Fragment getItem(int position) {
fragment = new WallpaperActivityFragment();
bundle = new Bundle();
bundle.putInt("position", position);
fragment.setArguments(bundle);
return fragment;
}
#Override
public CharSequence getPageTitle(int position) {
return categoriesTab.get(position).getCategoryName();
}
#Override
public int getItemPosition(Object object) {
return super.getItemPosition(object);
}
}
and this is the fragment
public class WallpaperActivityFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.wallpaper_content_fragment,container,false);
}
}
and this is the xml that contains the viewpager and tablayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/tablayout_linear"
android:orientation="horizontal" >
<include layout="#layout/category_btn"/>
<android.support.design.widget.TabLayout
android:id="#+id/activity_wallpapers_content_tablayout"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#FFFFFF"
app:tabGravity="fill"
app:tabMaxWidth="0dp"
app:tabMode="fixed" />
</LinearLayout>
<android.support.v4.view.ViewPager
android:id="#+id/activity_wallpapers_content_viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layout_below="#+id/tablayout_linear"
android:background="#FFF123" />
I already include it inside activity_wallpaper........... now i cant get the data with retrofit but how to do like (setTabText something like this)
of course this is in the BaseActivity
public void setupTabLayout(TabLayout tabLayout, ArrayList<Category> categoriesTab) {
for (int i = 0; i < tabLayout.getTabCount(); i++) {
RelativeLayout customTab = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.page_content_custom_tab, null);
TextView tabTitle = (TextView) customTab.findViewById(R.id.activity_music_page_content_tab_title);
tabTitle.setTextSize(15);
tabTitle.setText(categoriesTab.get(i).getCategoryName());
tabTitle.setTextColor(ContextCompat.getColor(this, 0));
tabLayout.getTabAt(i).setCustomView(customTab);
}
}
the json i'm getting contains id and tabs title
{
"categories": [
{
"ID": "18",
"CategoryName": "Inside Yerevan"
},
{
"ID": "1",
"CategoryName": "Armenia"
},
{
"ID": "2",
"CategoryName": "National Days"
},
{
"ID": "17",
"CategoryName": "Armenian Taraz"

"CategoryName": "Funny"
},
{
"ID": "15",
"CategoryName": "National Holida"
},
{
"ID": "16",
"CategoryName": "Sky"
}
]
}

I just wrote my viewpager and tablayout code inside server response and everything works
public class WallpaperPageActivity extends BaseActivity {
private ViewPager mViewPager;
private TabLayout mTabLayout;
private WallpaperActivityFragmentAdapter wallpaperActivityFragmentAdapter;
private CategoryList resultCategories;
private ArrayList<Category> categoriesTab = new ArrayList<>();
protected ApiInterface service;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_wallpaper);
service = RestApiClient.getClient();
mViewPager = (ViewPager) findViewById(R.id.activity_wallpapers_content_viewpager);
mTabLayout = (TabLayout) findViewById(R.id.activity_wallpapers_content_tablayout);
getCategoryNames();
}
public void getCategoryNames() {
Call<CategoryList> call = service.requestCategoryList("get_categories_wallpaper");
call.enqueue(new Callback<CategoryList>() {
#Override
public void onResponse(Response<CategoryList> response) {
Log.d("wow", "Status Code = " + response.code());
if (response.isSuccess()) {
// request successful (status code 200, 201)
resultCategories = response.body();
for (int i = 0; i < resultCategories.getCategories().size(); i++) {
categoriesTab.add(resultCategories.getCategories().get(i));
mViewPager.setAdapter(new WallpaperActivityFragmentAdapter(getSupportFragmentManager(),WallpaperPageActivity.this, categoriesTab));
mViewPager.getAdapter().notifyDataSetChanged();
setTablayoutItemsMode(mTabLayout, categoriesTab);
mTabLayout.setupWithViewPager(mViewPager);
setupTabLayout(mTabLayout, categoriesTab);
}
} else {
Log.d("wow", "error = ");
}
}
#Override
public void onFailure(Throwable t) {
}
});
}
public void setTablayoutItemsMode(TabLayout tabLayout, List<Category> categories) {
if (categories.size() > 3)
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
else {
tabLayout.setTabMode(TabLayout.MODE_FIXED);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
}
}
}

You are making async call so the app does not know when you did reach the data. Please add mViewPager.getAdapter().notifyDataSetChanged(); in onResponse callback after your for loop

Set Image array in recyclerview from json data in android

In my app I have got some json data from url. I have deserialize those data in controller class. Now I want to show those image into recyclerview.This recyclerview will be shown in detail activity. I have devided the relative layout into two part. First half is for information and the second half is for a recyclerview. I tried with the follwing code. The problem is I am very new in android developing and I am not getting the correct logic of doing this. I have explained in detail below-
Here is my model class
public class NewsModel {
#Expose
private String id;
#Expose
private String title;
#Expose
private List<AppImage> appImages;
public List<AppImage> getAppImages() {
return appImages;
}
public void setAppImages(List<AppImage> appImages) {
this.appImages = appImages;
}
}
The AppImageClass is
public class AppImage {
#Expose
private String _id;
#Expose
private String alt;
#Expose
private String src;
public String get_id() {
return _id;
}
public void set_id(String _id) {
this._id = _id;
}
public String getAlt() {
return alt;
}
public void setAlt(String alt) {
this.alt = alt;
}
public String getSrc() {
return src;
}
public void setSrc(String src) {
this.src = src;
}
}
The adapter class is
public class NewsImageAdapter extends RecyclerView.Adapter<NewsImageAdapter.ImageHolder> {
private Context context;
private List<NewsModel> imageObject;
public NewsImageAdapter(Context context, List<NewsModel> imageObject) {
this.context = context;
this.imageObject = imageObject;
}
#Override
public ImageHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.newsdetail_image_row,parent,false);
return new ImageHolder(view);
}
#Override
public void onBindViewHolder(ImageHolder holder, int position) {
final NewsModel currentImage=imageObject.get(position);
for (int i = 0; i < currentImage.getAppImages().size() ; i++)
{
AppImage appImage = currentImage.getAppImages().get(i);
Picasso.with(holder.itemView.getContext()).load(appImage.getSrc()).into( holder.images[i] ); }
Picasso.with(holder.itemView.getContext());
}
#Override
public int getItemCount() {
return imageObject.size();
}
public class ImageHolder extends RecyclerView.ViewHolder {
public ImageView images;
public ImageHolder(View itemView) {
super(itemView);
images= itemView.findViewById(R.id.news_image);
}
}
}
In Deatil activity
public class DetailNews extends AppCompatActivity {
private List<NewsModel> newsObject;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.news_detail);
setUpUIViews();
//newsObject=getAllImageList();
}
private void setUpUIViews() {
recyclerView = (RecyclerView)findViewById(R.id.image_list);
recyclerView.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(DetailNews.this);
recyclerView.setLayoutManager(layoutManager);
adapter = new NewsImageAdapter(this,newsObject );
recyclerView.setAdapter(adapter);
}
private List<NewsImageModel> getAllImageList() {
//how to set image here?
return images;
}
The json data looks like this
[
{ "id": "5925280ec925a9a6dd5173bb",
"title": "Headline",
"appImages": [
{
"alt": "",
"src": "source1",
"_id": "12213"
},
{
"alt": "",
"src": "source2",
"_id": "fdgdg"
},
{
"alt": "",
"src": "source3",
"_id": "fdfdfdf"
},
{
"alt": "",
"src": "source4",
"_id": "599d9018daf57d002c100ffa"
},
{
"alt": "",
"src": "source5",
"_id": "f7879"
}
],
},
{ "id": "5925280ec925a9a6dd5173bb",
"title": "Headline",
"appImages": [
{
"alt": "",
"src": "source1",
"_id": "12213"
},
{
"alt": "",
"src": "source2",
"_id": "fdgdg"
},
{
"alt": "",
"src": "source3",
"_id": "fdfdfdf"
},
{
"alt": "",
"src": "source4",
"_id": "599d9018daf57d002c100ffa"
},
{
"alt": "",
"src": "source5",
"_id": "f7879"
}
],
},
]

You should use one "raw/item" for each image. You don't need use "Picasso" to load the images, you can use something like:
In your RecyclerView.Adapter
.
.
.
#Override
public void onBindViewHolder(ViewHolderCustom viewHolder, final int position) {
viewHolder.setImage("imageUrl");
}
static class ViewHolderCustom extends RecyclerView.ViewHolder{
private final ImageView imageViewPhotoUrl;
ViewHolderCustom(View v) {
super(v);
imageViewPhotoUrl = (ImageView) v.findViewById(R.id.iv_photo_url);
}
void setImage(String photo) {
if (photo != null && !photo.isEmpty())
new DownloadImageTask(imageViewPhotoUrl)
.execute(photo);
}
}
.
.
.
Your DownloadImageTask:
public class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
private ImageView bmImage;
public DownloadImageTask(ImageView bmImage) {
this.bmImage = bmImage;
}
protected Bitmap doInBackground(String... urls) {
String urlDisplay = urls[0];
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(urlDisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
e.printStackTrace();
}
return mIcon11;
}
protected void onPostExecute(Bitmap result) {
if (result != null)
bmImage.setImageBitmap(result);
}
}

How to set Layout to RecyclerView in android

I want to load data from server and show in my application (RecyclerView), for this job, when the application starts it shows 10 posts and when scrolling recyclerView show another post .
I write below codes but when get other 10 posts, not show loading layout! I want when get other 10 posts, first show loading layout then show other 10 posts!
For connect to internet I use Retrofit v2 and for custom Endless methos for recyclerView I use this class : EndLess Class
My Activity codes:
public class Category_page extends AppCompatActivity implements ConnectivityReceiver.ConnectivityReceiverListener {
private static final long RIPPLE_DURATION = 250;
private Toolbar toolbar;
private TextView toolbar_title;
private ImageView toolbar_menuImage;
private Button categoryCheckNet_button;
private RelativeLayout root;
private CategoryAdapter mAdapter;
private RecyclerView cat_recyclerView;
private LinearLayoutManager mLayoutManager;
private RelativeLayout loadLayout, checkNetLayout;
private String catTitle = "";
private Integer catID;
private Bundle bundle;

How can I show loading layout when get other 10 posts?

create a layout for loadmore with the progressbar in activity layout and set its visibility to gone , now setVisibility of your loadMore layout to visible programmatically inside public void onLoadMore(int current_page) method and set it back to gone in the response of your webservice(in onResponse and onFailure methods)
load_more.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/load_more"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#AA000000"
android:gravity="center"
android:visibility="gone"
android:padding="5dp">
<ProgressBar
android:id="#+id/more_progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toRightOf="#+id/more_progress"
android:padding="5dp"
android:text="Loading results..."
android:textColor="#ffffff"
android:textSize="#dimen/medium_text_size" />
</RelativeLayout>
In your activity xml file include load_more like -
listing_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:background="#color/listing_background"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_weight="1"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycleView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textSize="#dimen/medium_text_size"
android:gravity="center"
android:id="#+id/noListFound"
android:textColor="#color/orange"
android:text="No List found Please click here to add a new one"
android:visibility="gone"
android:padding="#dimen/header_margin"/>
</RelativeLayout>
<include layout="#layout/load_more"/>
</LinearLayout>
BaseLoadMoreActivity.java
public abstract class BaseLoadMoreActivity extends Activity {
#BindView(R.id.recycleView)
RecyclerView recyclerView;
#BindView(R.id.load_more)
RelativeLayout loadMore;
private LinearLayoutManager ll;
private int page = 1;
private boolean isNoData = false;
private boolean isLoading = false;
private RecyclerView.OnScrollListener scrollListener = new RecyclerView.OnScrollListener() {
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
if (dy > 0) //check for scroll down
{
int visibleItemCount = ll.getChildCount();
int totalItemCount = ll.getItemCount();
int pastVisiblesItems = ll.findFirstVisibleItemPosition();
if (!isLoading && !isNoData) {
if ((visibleItemCount + pastVisiblesItems) >= totalItemCount) {
loadMore.setVisibility(View.VISIBLE);
page++;
LoadMoreList();
isLoading = true;
}
}
}
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ll = new LinearLayoutManager(this);
ll.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(ll);
recyclerView.addOnScrollListener(scrollListener);
}
public abstract void LoadMoreList();
}
Now extends your category_page.java with BaseLoadMoreActivity and change code
#Override
public void LoadMoreList() {
boolean isConnected = ConnectivityReceiver.isConnected();
retrofitData(isConnected);
}
private void retrofitData(boolean isConnect) {
if (isConnect) {
Retrofit_ApiInterface apiInterface = Retrofit_ApiClient.getClient().create(Retrofit_ApiInterface.class);
Call<R_CatModelResponse> call = apiInterface.getCatResponse(catID);
call.enqueue(new Callback<R_CatModelResponse>() {
#Override
public void onResponse(Call<R_CatModelResponse> call, Response<R_CatModelResponse> response) {
if (response != null) {
models = response.body().getCat_posts();
mAdapter = new CategoryAdapter(context, cat_recyclerView, models);
cat_recyclerView.setAdapter(mAdapter);
loadMore.setVisibility(View.GONE);
isLoading = false;
} else {
loadMore.setVisibility(View.GONE);
isLoading = false;
Toast.makeText(Category_page.this, "Error 2", Toast.LENGTH_SHORT).show();
TastyToast.makeText(context, "خطایی رخ داده است", TastyToast.LENGTH_LONG, TastyToast.ERROR);
}
checkNetLayout.setVisibility(View.GONE);
}
#Override
public void onFailure(Call<R_CatModelResponse> call, Throwable t) {
loadMore.setVisibility(View.GONE);
isLoading = false;
//TastyToast.makeText(context, "لطفا برنامه را مجددا باز کنید", TastyToast.LENGTH_LONG, TastyToast.ERROR);
Toast.makeText(Category_page.this, "Error 2", Toast.LENGTH_SHORT).show();
//Cat_EmptyLayout.setVisibility(View.VISIBLE);
Log.e("CatResponseError", "Error : " + t);
}
});
} else {
loadMore.setVisibility(View.GONE);
isLoading = false;
checkNetLayout.setVisibility(View.VISIBLE);
if (mAdapter != null) {
mAdapter.clear();
cat_recyclerView.setAdapter(mAdapter);
}
categoryCheckNet_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
loadData();
}
});
}
}
Please remove code of finding recycleView and setting layout manager of it from
category_page.java as we did it in BaseLoadMoreActivity otherwise code will not work.
I have just provided code for sample. Hope it will help you...

You didn't implement the getItemViewType and getItemCount correctly:
#Override
public int getItemViewType(int position) {
if (position < mDataSet.size()) {
return VIEW_ITEM;
}
return VIEW_PROG;
}
and
#Override
public int getItemCount() {
return mDateSet.size() + 1;
}
additionally replace the notifyItemRangeInserted(start + 1, end); with notifyDataSetChanged(); in addNewItem
EDIT
keep a boolean private boolean hasMore = true in your adapter and edit the getItemCount() like this:
#Override
public int getItemCount() {
if (hasMore)
return mDateSet.size() + 1;
else
return mDataSet.size();
}
You'll have two cases:
1. If you know from your previous response that there aren't anymore items you can load, set your hasMore = false .
2. If you don't know that, then in your Activity when you get the response in onLoadMore if response== null || response.body() == null || response.body().getCat_posts().size() == 0 set hasMore = false.
It all depends on the response you get from the server
Edit
in your adapter add a method
public void setHasMore(boolean hasMore) {
this.hasMore = hasMore;
}
in the onLoadMore
call.enqueue(new Callback<R_CatModelResponse>() {
#Override
public void onResponse(Call<R_CatModelResponse> call, Response<R_CatModelResponse> response) {
if (response != null) {
adapter.setHasMore(response.body().getPages() !=current_page+1)
mAdapter.addNewItem(response.body().getCat_posts());
//loadLayout.setVisibility(View.GONE);
} else {
