Solved , I should use Static for my Models in declerating . thanks all
I just went through this topic filter recycler view using search view and I did all the steps. Now when I search in recycler view it will filter my recycler view but when I press back space and remove a char it wont show the removed items! My recycler view is also empty after the search.
This is my RecyclerView adapter:
package com.webapp.masoud.application.myRecyclerAdapter;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.support.v7.widget.RecyclerView;

public class myRecyclerAdapter extends RecyclerView.Adapter<myRecyclerAdapter.myRecyclerViewHolder> {
private Context context;
ArrayList<NewsModel> myModels;
public myRecyclerAdapter(Context context, ArrayList<NewsModel> myModels) {
this.context = context;
this.myModels = myModels;
}
@Override
public myRecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(R.layout.channels_layout, parent, false);
return new myRecyclerViewHolder(v);
}
@Override
public void onBindViewHolder(myRecyclerViewHolder holder, int position) {
final NewsModel newsModel = myModels.get(position);
holder.edt_Title.setText(newsModel.title);
holder.edt_Dis.setText(newsModel.discription);
holder.txt_Category.setText(newsModel.category);
Picasso.with(context).load(newsModel.image).into(holder.img_Channel);
holder.btn_Join.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String username;
if (newsModel.username.startsWith("@")){
username = "http://telegram.me/" + newsModel.username.substring(1);
}
else{
username = "http://telegram.me/" + newsModel.username;}
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(username));
context.startActivity(i);
}
});
}
@Override
public int getItemCount() {
return myModels.size();
}
public void animateTo(ArrayList<NewsModel> models) {
applyAndAnimateRemovals(models);
applyAndAnimateAdditions(models);
applyAndAnimateMovedItems(models);
}
public void setModels(ArrayList<NewsModel> models) {
myModels = new ArrayList<>(models);
}
public NewsModel removeItem(int position) {

return model;
}

}

myModels.add(toPosition, model);
notifyItemMoved(fromPosition, toPosition);
}

for (int i = myModels.size() - 1; i >= 0; i--) {
final NewsModel model = myModels.get(i);
if (!newModels.contains(model)) {
removeItem(i);
}
}
}
private void applyAndAnimateAdditions(ArrayList<NewsModel> newModels) {
for (int i = 0, count = newModels.size(); i < count; i++) {
final NewsModel model = newModels.get(i);

}
}
}

}
}
}

This is my newsModels:

/**

*/
public class NewsModel implements Serializable {
public String id;
public String title;
public String discription;
public String image;
public String category;
public String username;
public NewsModel(String title, String description,String image,String id,String category,String username) {
this.id = id;
this.title = title;
this.discription = description;
this.image = image;
this.category = category;
this.username=username;
}
public NewsModel() {
}
}
Please help me, thanks. Sorry for my bad English!
