How to get value to Recyclerview-Adapter from another Activity and set value to Recyclerview of particular...
In my Application I am opening another Activity, lets say SecondActivity on item click of RecyclerView, SecondActivity pass some data to RecyclerView adapter on click of submit button (RecyclerView adapter holds on FirstActivity).
I have to set that data to item click position only, how will I achieve this?
I have tried to get adapter position and used notifyItemchanged(position) in onBindViewHolder() method.

@Override public void onBindViewHolder(final ParentViewHolder holder, final int position) { holder.tvTotal.setText( Total); MovieAdapter.this.notifyItemChanged(holder.getAdapterPosition()); } Value of Total send by Activity B

This is wrong way... You have to change data in your string/entity list... and then you have to callnotifyItemChanged(holder.getAdapterPosition())

You can set listener either in your ViewHolder class or in onBindViewHolder method.
ViewHolder:
public MyViewHolder(View v, final Activity activity) {
super(v);
title = v.findViewById(R.id.controller_title);
v.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(activity, MainPanelActivity.class);
intent.putExtra("controllerName",title.getText().toString());
activity.startActivity(intent);
activity.finish();
}
});
}
onBindViewHold:
@Override
public void onBindViewHolder(final MyViewHolder holder, final int position) {
Controller controller = controllerList.get(position);
holder.title.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
CustomControllerInfoDialog dialog = new CustomControllerInfoDialog(activity, holder);
dialog.show();
}
});
}
in ViewHolder you can pass reference of the view and in BindView method you can pass position. so you will be able to add those data where you want
