android - Adding Items in RecycleView Dynamically using a button

Question

I have a button(save contact) to save contacts ,the button when pressed get name and email from edit text and should dynamically add 1 list item in recycle view

The save button is in fragment

This is the name which i am extracting

company_name=(EditText)view.findViewById(R.id.edittext_companyname_createMeeting);

When i click on lead it should add in the existing recycleview

 leads.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

     newValueAdapter.newAddeddata(company_name.getText().toString());*/
            }
        });

The recycle view already have a arraylist,how do i add new value to the arraylist and again call oncreate

I tried to extract company name and send it to the adapter of that recycler view but it dint work

Adapter of RecyclerView

public class NewleadsAdapter extends RecyclerView.Adapter<NewleadsAdapter.MyViewHolder> {

    Context context;

    int positionbundle;
    ArrayList<NewleadsPOJO> datalist;
    public NewleadsAdapter(Context context, ArrayList<NewleadsPOJO> datalist,int positionbundle){

        this.context=context;
        this.datalist=datalist;
        this.positionbundle=positionbundle;

    }
   /* public NewleadsAdapter(){}*/

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view=LayoutInflater.from(context).inflate(R.layout.custom_new_leads,parent,false);
        MyViewHolder myViewHolder=new MyViewHolder(view);
        return myViewHolder;
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {


        holder.leads_company.setText(datalist.get(position).getLeads_company());
        holder.leads_date.setText(datalist.get(position).getLeads_date());
        holder.leads_time.setText(datalist.get(position).getLeads_time());
        if (positionbundle == 1){
          /*  holder.icon1.setVisibility(View.GONE);*/
            holder.icon1.setImageResource(R.drawable.taskcompletednewblue);
    }else{}

        Log.e("Create_meetingdate_ArrayList:", datalist.get(0).getLeads_company());   /* Arrays.deepToString(data.toArray())*/
        System.out.println(datalist.get(0).getLeads_company());
    }

    @Override

        return datalist.size();

Answer 1

Add this method to your adapter and call on button click.

public void newAddeddata(String company_name){
        NewleadsPOJO newValue=new NewleadsPOJO();
        newValue.setLeads_company(company_name);
        datalist.add(newValue);
        notifyDataSetChanged();
    }

Add following method to NewLeadFrag

public NewleadsAdapter getAdapter(){
   return adapter;
}

now in Createmeetingfrag

leads.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                NewLeadFrag fragment = getFragmentManager().findFragmentByTag("NewLeadFrag_TAG"); //set tag of fragment when you add with fragment manager. and if you are using support library use getSupportFragmentManager()
               if(fragment!= null){
                    fragment.getAdapter().newAddeddata(company_name.getText().toString());
                }

            }
        });
