I can't understand you ... You have an Button and want when you click on it to close the activity or what ? If it's that, then write this code :
Button yourButton = (Button) view.findViewById(R.id.your_button_id);
yourButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getActivity().onBackPressed();
}
});

How to send value from one fragment to another fragment from Recyclerview Adapter. Then close the first fragment and open the new Fragment

I need to send a value when i click on a row in recyclerview to another fragment (I thin on OnBind in the adapter). Then i need to close the fragment that contain the recyclerview and open the receiver fragment. I read somewhere that we can use bundle, but I am pretty new to android programming so I am confused.
This is the Fragment that contain RecyclerView

You can send data using bundle to fragment.
EG. `Bundle data = new Bundle();
data.putString("key", "value");
NewFragment newFragment = new NewFragment ();
newFragment.setArguments(eventDetailsData);`
Then load fragment.
To kill/remove current fragment execute below code
getActivity().onBackPressed();

How to pass data from activity to fragment class?

I created a new project tabbed view. I want three layout on my main screen 1st home 2nd category 3rd favorite. I have code of Home activity which is fragment activity the code is here

Define variable like public static String test=""; in Activity then in Fragment get it like String test1=ActivityName.test; now you have value of test into test1

First of all, you need to understand that Activity contains fragments, not vice versa. So one way to make your idea come true is to make your activity contain three fragments:
1)Home
2)Category
3)Favorite
To send data from activity to fragment usually use Bundle object.
Then create the instance of the fragment and put bundle there by setArguments(yourBundle) method.
It is the main idea, if you want details then read official documentation and use search on SOF.

use a Bundle:
Fragment fragment = new YourFragment();
Bundle bundle = new Bundle();
bundle.putString("yourArg","yourType"); //this could be String, int, float,etc
fragment.setArguments(bundle);
getSupportFragmentManager().beginTransaction().replace(R.id.yourContainer,fragment).commit();
and in your Fragment's onCreateView:
Bundle bundle = getArguments();

how can rerun Asynctask inside fragment from recyclerview

I have fragment with Asynctask class which needs to Re-Run the Asynctask from my Recyclerview adapter class.
Note : I want re run asynctask inside of viewHolder.buttonnext.setOnClickListener(new View.OnClickListener() { in onBindViewHolder and when use this line.
new maghalat.GetContacts().execute(); //maghalt is name of fragment contain GetContacts asynctask function
Give me red line under this line without any suggestion
this is my adapter :
public class DataAdapter extends RecyclerView.Adapter<DataAdapter.ViewHolder> {
private Context context;
List<jsonContent> jcontent;
public DataAdapter(Context context, List<jsonContent> jcontent) {
this.context=context;
this.jcontent=jcontent;
}
#Override
public DataAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view ;
if(i == R.layout.card_row) {
view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.card_row, viewGroup, false);
}else {
view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.button_card, viewGroup, false);
}
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(final ViewHolder viewHolder,int i) {
if(i == jcontent.size()) {
viewHolder.buttonnext.setOnClickListener(new View.OnClickListener() {
#Override

Update ListView Record Duplicated Android

I put a limit of 15 records to be displayed in my listview. The 15 records successfully displayed but when i clicked on load more button, it add the previous 15 records and the new records too.

I use articlesAdapter.notifyDataSetChanged(); set too but the issue remains. i believe it has something to do with articlesFiltered.size()/15)+1.

}

UPDATE
and the HttpFunction getMoreArticles()
public static ArrayList<Article> getMoreArticles(int page){
String url=LAST_ARTICLE_URL;
if(url.endsWith(".php"))
url+="?page="+page;
else
url+="&page="+page;
String response=getResponse(url);
if(!ERROR.equals(response)){
return JsonParsingFunctions.parseArticles(response);
}
return null;
}

What is happening is concatenation in the method call. articlesFiltered.size()/15 is giving 1, then the +1 is not ADDING 1, it is concatenating 1, i.e 1+1 = 11 NOT 2. You could create a method
public int addOne(int i){
return i+1;
}
and use
ArrayList<Article>moreArticles=HTTPFunctions.getMoreArticles(addOne((articlesFiltered.size()/15)));
That should work providing the rest of the code is good

what variable is your adapter?
you notify your adapter but i don't see that you add datas to your articlesAdapter
