This is my code.
Here I am taking HealthActivity and in this class by using recycler view I have displayed testList in recycler view. I am passing testList whichever I am selecting through checkbox to AmountCartActivity of recycler View, And, I am calculating total amount of the selected testList and I am getting the result and that result I am passing to the AmountCart Activity through bundle and I am getting correct result in bundle, but, when I am trying to display total amount in a textView its showing me nothing.
And, my second problem is,
I am trying to display serial number to to my AmountCartActivity of recycler view whichever I am selecting from previous HealthCartActivity using checkbox. And, I have implemented some code but I am not getting how to solve it. please help me.

For Issue#1
Data should be passed onto the Adapter through constructor. The issue could simply be adding another parameter to the constructor:
public MyAdapter(List<AmountCartModel> context, List<AmountCartModel> myDataList) {
this.context = context;
myDataList = this.myDataList;
}
Or,
To add selection support to a RecyclerView instance:
Determine which selection key type to use, then build a ItemKeyProvider.
Implement ItemDetailsLookup: it enables the selection library to access information about RecyclerView items given a MotionEvent.
Update item Views in RecyclerView to reflect that the user has selected or unselected it.
The selection library does not provide a default visual decoration for the selected items. You must provide this when you implement onBindViewHolder() like,
In onBindViewHolder(), call setActivated() (not setSelected()) on the View object with true or false (depending on if the item is selected).
Update the styling of the view to represent the activated status.
For Issue #2
Try using passing data through intents.
The easiest way to do this would be to pass the serial num to the activity in the Intent you're using to start the activity:
Intent intent = new Intent(getBaseContext(), HealthServicesActivity.class);
intent.putExtra("EXTRA_SERIAL_NUM", serialNum);
startActivity(intent);
Access that intent on next activity
String sessionId= getIntent().getStringExtra("EXTRA_SERIAL_NUM");

Just Modify your function and Add check for null or "" .
it will work fine
private ArrayList<SuggestGetSet> filter(ArrayList<SuggestGetSet> models, String query) {
if(TextUtils.isEmpty(query)){
return models;
}
query = query.toLowerCase();
final ArrayList<SuggestGetSet> filteredModelList = new ArrayList<>();
for (SuggestGetSet model : models) {
final String text = model.getName().toLowerCase();
if (text.contains(query)) {
filteredModelList.add(model);
}
}
return filteredModelList;
}

How to send object value from RecyclerView Item to Another Activity

From a JSON array that I am parsing, I want to send a particular object value (using intent putExtra) to another activity. I have read this this question
and the accepted answer but I don't want to send all the values, in my case I only want to send the news_id as an integer to NewsDetails.class.
And I tried using the accepted answer to do it but I got stuck.

#Override

You can send single value also instead of complete object like this -
#Override
public void onClick(View v) {
if (v.getId() == newsExcerpt.getId()) {
Intent intent = new Intent(context, NewsDetails.class);
intent.putExtra("PostId",<your_news_id_here>);
startActivity(intent);
}
}
}
In your case, remove onClick(View v) and change your onBindViewHolder() to setOnClickListener() on newsExcerpt like this -
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (holder instanceof TextViewHolder) {
NewsItems newsList = mNewsItems.get(position);
((TextViewHolder) holder).newsTitle.setText(newsList.getNews_title());
((TextViewHolder) holder).newsExcerpt.setText(newsList.getNews_excerpt());
((TextViewHolder) holder).newsId.setText(String.valueOf(newsList.getNewsId()));
((TextViewHolder) holder).newsExcerpt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(context, NewsDetails.class);
intent.putExtra("PostId",newsList.getNewsId()); //Any getter of your class you want
startActivity(intent);
});
} else {
((ProgressViewHolder) holder).progressBar.setIndeterminate(true);
((ProgressViewHolder) holder).loadButton.setText(R.string.reload);
}
}

I don't want to send all the values
You dont' have to send all, It's up to you and your needs.
Intent i = new Intent(context, DestActivity.class);
i.putExtra(KEY_NEWS_ID, news_id );
On the other end:
int news_id = getIntent().getIntExtra(KEY_NEWS_ID, defaultValue);

This problem is caused because of overlapping fragments and i was starting the fragment like this
fragment=ProductFragment.newInstance();
getSupportFragmentManager().beginTransaction()
.replace(R.id.productFragment,fragment )
.commit();
so making it simply
fragment=ProductFragment.newInstance();
solved my problem.
Thanks guys for help #MohammadAllam
