how to remove item from Recyclerview

how to remove item from Recyclerview - android

friends...
In my project, I am creating a list of images from the server and showing in Recyclerview.
now I want to remove a particular item from the list when I click on the verify button.
I tried to hide holder.itemview but its see again when I scroll.
I just want to remove or hide that item which is verified once.
here is my code :
1) Main activity
public class MainActivity extends AppCompatActivity {
private static final String url = "www.mysite.com/api/api-id-list.php?action=imgs";
private ProgressDialog mDetailProgress;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_main_activity);
LoadRecyclerView();
}
private void LoadRecyclerView() {
mDetailProgress = new ProgressDialog(this);
mDetailProgress.setTitle("Loading images");
mDetailProgress.setMessage("Please Wait...");
mDetailProgress.setCanceledOnTouchOutside(false);
mDetailProgress.show();
final RecyclerView imgList = (RecyclerView) findViewById(R.id.imgList);
imgList.setLayoutManager(new LinearLayoutManager(this));
StringRequest request = new StringRequest(url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
GsonBuilder gsonBuilder = new GsonBuilder();
Gson gson = gsonBuilder.create();
Image[] images = gson.fromJson(response, Image[].class);
imgList.setAdapter(new ImageAdapter(MainActivity.this, images));
mDetailProgress.dismiss();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getBaseContext(), "Something went wrong..!", Toast.LENGTH_LONG);
}
});
RequestQueue queue = Volley.newRequestQueue(this);
queue.add(request);
}}
2) ImageAdapter
public class ImageAdapter extends RecyclerView.Adapter<ImageAdapter.ImageViewHolder> {
private ProgressDialog mDetailProgress;
private Context context;
private Image[] data;
Button btn_ban, btn_verify;
private View view;
public ImageAdapter (Context context, Image[] data) {
this.context = context;
this.data = data;
}
#NonNull
#Override
public ImageViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int i) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
view = inflater.inflate(R.layout.single_item, parent, false);
return new ImageViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull final ImageViewHolder holder, final int position) {
final Image imagelist = data[position];
holder.userCode.setText(imagelist.getCode());
Glide.with(holder.userImage.getContext()).load(imagelist.getIdPhoto()).into(holder.userImage);
btn_verify.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
holder.itemView.setVisibility(View.GONE);
}
});
}
#Override
public int getItemCount() { return data.length; }
public class ImageViewHolder extends RecyclerView.ViewHolder {
TextView userCode;
ImageView userImage;
public ImageViewHolder(#NonNull View itemView) {
super(itemView);
userImage = (ImageView) itemView.findViewById(R.id.card_iv_img);
userCode = (TextView) itemView.findViewById(R.id.card_tv_code);
btn_ban = (Button) itemView.findViewById(R.id.btn_ban);
btn_verify = (Button) itemView.findViewById(R.id.btn_verify);
}
}}
3) Image.java
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Image {
#SerializedName("per_ID")
#Expose
private String perID;
#SerializedName("code")
#Expose
private String code;
#SerializedName("first_nm")
#Expose
private String firstNm;
#SerializedName("last_nm")
#Expose
private String lastNm;
#SerializedName("photo_ID")
#Expose
private String photoID;
#SerializedName("id_photo")
#Expose
private String idPhoto;
public String getPerID() {
return perID;
}
public void setPerID(String perID) {
this.perID = perID;
}
public Image withPerID(String perID) {
this.perID = perID;
return this;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public Image withCode(String code) {
this.code = code;
return this;
}
public String getFirstNm() {
return firstNm;
}
public void setFirstNm(String firstNm) {
this.firstNm = firstNm;
}
public Image withFirstNm(String firstNm) {
this.firstNm = firstNm;
return this;
}
public String getLastNm() {
return lastNm;
}
public void setLastNm(String lastNm) {
this.lastNm = lastNm;
}
public Image withLastNm(String lastNm) {
this.lastNm = lastNm;
return this;
}
public String getPhotoID() {
return photoID;
}
public void setPhotoID(String photoID) {
this.photoID = photoID;
}
public Image withPhotoID(String photoID) {
this.photoID = photoID;
return this;
}
public String getIdPhoto() {
return idPhoto;
}
public void setIdPhoto(String idPhoto) {
this.idPhoto = idPhoto;
}
public Image withIdPhoto(String idPhoto) {
this.idPhoto = idPhoto;
return this;
}}

First make data not array, but List, so it's easy to remove item;
Secondly set listener for verify button inside ViewHolder and inside OnClick remove item and notify adapter.
btn_verify.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int position = getAdapterPosition();
data.remove(position);
notifyItemRemoved(position);
}
});
Note: Setting OnClickListener inside ViewHolder makes sure that only correct item is removed by using getAdapterPosition() to get correct position.
Position provided by onBindViewHolder might be invalid after new items are inserted.

Your code very confusing so i just write my solution.
public class SomeAdapter extends RecyclerView.Adapter<SomeAdapter.SomeViewHolder> implements Filterable{
...
#Override
public Filter getFilter() {
Filter filter = new Filter() {
#Override
protected FilterResults performFiltering(CharSequence charSequence) {
mMainList = mYourJSONResponseList;
FilterResults results = new FilterResults();
ArrayList<YourModel> mFilter_list = new ArrayList<>();
//Place your logic
for (YourModel model : mMainList) {
if(model.getName().
toLowerCase().contains(text.toLowerCase())) {
mFilter_list.add(model);
}
}
results.count = mFilter_list.size();
results.values = mFilter_list;
return results;
}
#Override
protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
mMainList = (ArrayList<YourModel>) filterResults.values;
notifyDataSetChanged();
}
};
return filter;
}
And add this into your text listener
#Override
public void afterTextChanged(Editable s) {
//Add this
adapter.getFilter().filter(s.toString())
}
NOTE!! You will show mMainList only this list in your RecyclerView, And check nullpointerexceptions

android -how to bind the image loaded from picasso to recycler view

I have list of data in MenuItemsModel(model) class along with image url and two strings fetching from the API. How can I load the image url with Picasso and how to bind the loaded image to recyclerview?
Here is my code
Code for model class
public class MenuItemsModel {
public int image;
public String itemName;
public String itemCost;
public MenuItemsModel(int image, String itemName, String itemCost) {
this.image = image;
this.itemName = itemName;
this.itemCost = itemCost;
}
public int getImage() {
return image;
}
public void setImage(int image) {
this.image = image;
}
public String getItemName() {
return itemName;
}
public void setItemName(String itemName) {
this.itemName = itemName;
}
public String getItemCost() {
return itemCost;
}
public void setItemCost(String itemCost) {
this.itemCost = itemCost;
}
}
Here is my RecyclerAdapter class
public class MenusRecyclearView extends
RecyclerView.Adapter<MenusRecyclearView.RecyclerViewHolder> {
Context context;
List<MenuItemsModel> menuItemsModel;
public MenusRecyclearView(Context context, List<MenuItemsModel> menuItemsModel) {

holder.imageView.setImageResource(menuItemsModel.get(position).getImage());
holder.ItemName.setText(menuItemsModel.get(position).getItemName());
holder.ItemCost.setText(menuItemsModel.get(position).getItemCost());
//Picasso.with(context).load(menuItemsModel.get(position).getImage()).into(holder.imageView);

Well, you are on the right track. You need to uncomment this line:
//Picasso.with(context).load(menuItemsModel.get(position).getImage()).into(holder.imageView);
And, the .getImage() needs to become your URL. That means, you should store the image url inside MenuItemsModel. Now your image is an int, and should be of a type of String so you can pass the URL to it.

How to add data into RecyclerView

In my application I want use two recyclerView into one Activity.
I want when click on items of one of this recylerView's items , add item to another recyclerView.

How can I it? Please help me

Inside onSend() , you need to add each objects to an arraylist which should be declared globally. Then call notifyItemInserted(arraylist.size()-1) in adapter to refresh recyclerview
public class SuggestFilmActivity ....
{ ArrayList<SuggestFilmAddUser> suggestFilmAddUserList=new ArrayList();
SuggestFilmUserAdapter suggestFilmUserAdapter;
......
......
protected void onCreate(Bundle savedInstance)
{....
....
....
suggestFilmUserAdapter = new SuggestFilmUserAdapter(context,
suggestFilmAddUserList);
suggestFilm_recyclerViewSendUser.setAdapter(suggestFilmUserAdapter);
.....
.....
}
public void onSend(int Id, String name, String image) {
SuggestFilmAddUser suggestFilmAddUser = new SuggestFilmAddUser();
suggestFilmAddUser.setId(id);
suggestFilmAddUser.setName(name);
suggestFilmAddUser.setImage(image);
suggestFilmAddUserList.add(suggestFilmAddUser);
suggestFilmUserAdapter.notifyItemInserted(suggestFilmAddUserList.size()-1)
}

now how can be able to fetch both popular movie data and high-rated movie data from https://developers.themoviedb.org ? can you help me ?

You have a method in your MainActivity called getPopularMovies() where you call service.getPopularMovies(), which uses the MoviesApiService #GET("/movie/popular"). You could create a similar API for high-rated movies, something like:
#GET("/movie/high_rated")
void getHighRatedMovies(Callback<Movie.MovieResult> cb);
Then create a similar getHighRatedMovies() method and depending on what the user selects, make a call to that method. The only difference would be you would call service.getHighRatedMovies instead of service.getPopularMovies().
To simplify the code to just one method, you could make a method called getMovies(), and then at the point when you initialize service.(something), set the correct method call.

How can i set another data into constructor DataModel in Retrofit in Android

In my application I should load data from server and for this job I use Retrofit library.

I don't know how can i add int[] into my constructor, because in retrofit fill the constructor with List<Retrofit_ColoniesModel> models = response.body().getCategories(); .
How can i fix my issue? I really need this tutorial, please help me. Thanks all <3

If the array of images is static (don't depend on the server) then you could just do the following:
public class Retrofit_ColoniesModel {
...
private static final int[] colImages = {
R.drawable.colonies_image_food,
R.drawable.colonies_image_medical,
R.drawable.colonies_image_tecgnolegy,
R.drawable.colonies_image_entertenement,
R.drawable.colonies_image_car,
R.drawable.colonies_image_model,
R.drawable.colonies_image_sport,
};
But if this array is not static (depends on the server response) then I suggest you to map to an array of Strings that describe each image, and the server should respond with those Strings, for example:
"images":["IMAGE1", "IMAGE2"]
And then have a helper class that could map between those string keys to the actual R.drawable resources.
Let me know if you need sample code.

Non-static Nested Classes (Inner Classes)
Non-static nested classes in Java are also called inner classes. Inner classes are associated with an instance of the enclosing class. Thus, you must first create an instance of the enclosing class to create an instance of an inner class. Here is an example inner class definition:
public class Outer {
public class Inner {
}
}
Here is how you create an instance of the Inner class:
Outer outer = new Outer();
Outer.Inner inner = outer.new Inner();
Notice how you put new after the reference to the outer class in order to create an instance of the inner class.
Non-static nested classes (inner classes) have access to the fields of the enclosing class, even if they are declared private. Here is an example of that:
