How to get child view from RecyclerView?

Use recyclerView.findViewHolderForLayoutPosition(position) or reyclerView.findViewHolderForAdapterPosition(position) to get the viewholder for postion. Then you can access any child from your viewholder.

Checkout Recyclerview

RecyclerView.ViewHolder holder = recycleView.findViewHolderForAdapterPosition(position); ImageView imageView = holder.itemView.findViewById(R.id.iv_product); 

This is a supplement to @Ravi Teja's answer. You can get the viewHolder from the recyclerView using position of the particular item, then get a particular view from the viewHolder as shown above

You can use RecyclerView's LayoutManager for it.

View view = layoutManager.findViewByPosition(position) 

Hope this helps someone: I was getting null pointer exceptions with:

• recyclerView.findViewHolderForAdapterPosition
• recyclerView.findViewHolderForItemId
• layoutManager.findViewByPosition.

The reason was that there is a slight delay for the viewholder to be created. I found the solution here: https://stackoverflow.com/a/33414430/7952427

I post an answer because which is really complex to findviews() from RecyclerView.

@Joe: After spending 4hours found one answer. Which gives me the proper view of the index.

mAdapter is adapter of RecyclerView View v = recyclerView.findViewHolderForItemId(mAdapter.getItemId(index/position)).itemView; 

Now just access your views by: v.findViewById(R.id.edittext) OR any id.

it helped me, make a 100 ms delay before manipulate it, like this:

Handler handler = new Handler(); mHandler.postDelayed(new Runnable() { @Override public void run() { // rcv is my recyclerview rcvStatus.getChildAt(1).setBackground(getActivity().getResources().getDrawable(R.drawable.disabled)); // or: rcvStatus.getChildAt(1).setClickable(false); } }, 100); 

Write this method in adapter.

 public Object getItem(int position) { return yourArrayList.get(position); } 

and you just need to call it like

yourAdapter.getItem(2); 

pass your required position. Hope it solves your problem.

now I understand your problem. you need to use interface for join recyclerview item and activity. you must define an interface class like below:

public interface IViewClick { public void onClickButtonAdd(); } 

add this parameter to your adapter class:

private IViewClick mListener; 

and initialize it in constructor with value that get from inputs. when user click on PLUS button, you send event to activity by this line:

 mListener.onClickButtonAdd(); 

in your activity class you must implements IViewClick interface and add your code there, like this:

@Override public void onClickButtonAdd() { /// TODO every thing that you want. /// change your toolbar values. } 

it is not good solution for you.

RecyclerView.ViewHolder holder = mRecyclerView.findViewHolderForItemId(mAdapter.getItemId(i));

I wouldn't recommend tracking the view list yourself. It could lead to weird issues with item updates, position updates, etc.

Instead on your SellRecordChangedEvent, use findViewHolderForAdapterPosition() instead of adapter.getView().

@Subscribe public void onEvent(SellRecordChangedEvent event){ sell.getSellRecords().set(event.getSellRecordPosition(), event.getSellRecord()); sell.recalculate(); int position = event.getSellRecordPosition(); View view = yourrecyclerview.findViewHolderForAdapterPosition(position); bus.post(new TransactionTitleChangedEvent(null, view)); } 

http://developer.android.com/reference/android/support/v7/widget/RecyclerView.html#findViewHolderForAdapterPosition(int)

And as a side note, it's better to implement an actual item click listener to the itemView on the ViewHolder instead of using touch listener. There's lots of examples of this online.

So the recyclerview and your product information are in 2 different fragments yes? You are expecting the recyclerview's views to update when they are not even in foreground? also you are changing adapter data item's data at position event.getSellRecordPosition() , but you are not notifying the adapter that its dataset changed, either by adapter.notifyDataSetChanged() or the other notifyItemChanged(position) methods.

I'd modify your onEvent() like so:

@Subscribe public void onEvent(SellRecordChangedEvent event){ sell.getSellRecords().set(event.getSellRecordPosition(), event.getSellRecord()); sell.recalculate(); int position = event.getSellRecordPosition(); MyViewHolder holder = adapter.onCreateViewHolder(yourRecyclerView, 0); adapter.onBindViewHolder(holder,position); View view = adapter.getView(position); bus.post(new TransactionTitleChangedEvent(null, view)); } 

Calling on createViewHolder and next BindViewHolder on your adapter will definitely update the views for that position, then your adapter.getView(position) should return you the latest view.

Here MyViewHolder is your viewholder class and yourRecyclerview, is the reference to your recycler view

for (int i = 0; i < recycler_view.getAdapter().getItemCount(); i++) { View viewTelefone = recycler_view.getChildAt(i); } 

If you want to replace text on a particular edit text for same position:

for (int i = 0; i < recycler_view.getAdapter().getItemCount(); i++) { if(adpterPostion==i) { View viewTelefone = recycler_view.getChildAt(i); EditText et_mobile = (EditText) viewTelefone.findViewById(R.id.et_mobile); et_mobile.setText("1111111"); } }
