I want to make recycle view with ViewModel and data binding following MVVM principle. But I don't know how to create data binding in onCreateViewHolder(). What I should do?

override fun onCreateViewHolder(parent: ViewGroup,
 viewType: Int): MyAdapter.MyViewHolder 
 // create a new view
 val inflator = LayoutInflater.from(parent.context)

 val listItemBinding :ResItemBinding = DataBindingUtil.inflate(inflator, R.layout.res_item, parent, false)
 // set the view's size, margins, paddings and layout parameters
 return MyViewHolder(listItemBinding.root)

I tried the above solution but it does not work properly

  Usually, I pass the binding object to the holder. The holder then has a bind() function that I call from onBindViewHolder(), so I can pass the model/viewmodel data to the holder. The holder then updates the binding object as needed. And, since this is a RecyclerView, the holder also calls executePendingBindings() on the binding object.

You can use data binding as below

private YourAdapterBinding mYourAdapterBinding

 @Override
 public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) 
 mYourAdapterBinding = DataBindingUtil.inflate(LayoutInflater.from(parent.getContext()),R.layout.your_custome_layout,parent,false);
 View itemView = mYourAdapterBinding.getRoot();
 return new ViewHolder(itemView);
 


 @Override
 public void onBindViewHolder(ViewHolder viewHolder, int position) 

 Guide guide = mGuideOptionList.get(position);
 viewHolder.textView.setText(mYourAdapterList.get(position).getTitle());
 viewHolder.parent.setOnClickListener(new View.OnClickListener() 
 @Override
 public void onClick(View v) 
 mYourListItem.onItemClick((int) v.getTag(),v);
 
 );

 mYourAdapterBinding.executePendingBindings();
 


 @Override
 public long getItemId(int position) 
 return super.getItemId(position);

You can use data binding as below

private YourAdapterBinding mYourAdapterBinding

 @Override
 public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) 
 mYourAdapterBinding = DataBindingUtil.inflate(LayoutInflater.from(parent.getContext()),R.layout.your_custome_layout,parent,false);
 View itemView = mYourAdapterBinding.getRoot();
 return new ViewHolder(itemView);
 


 @Override
 public void onBindViewHolder(ViewHolder viewHolder, int position) 

 Guide guide = mGuideOptionList.get(position);
 viewHolder.textView.setText(mYourAdapterList.get(position).getTitle());
 viewHolder.parent.setOnClickListener(new View.OnClickListener() 
 @Override
 public void onClick(View v) 
 mYourListItem.onItemClick((int) v.getTag(),v);
 
 );

 mYourAdapterBinding.executePendingBindings();
 


 @Override
 public long getItemId(int position) 
 return super.getItemId(position);
