@Override
public void onBindViewHolder(DataHolderNew holder, int position) {
    Intent intent=new Intent();

    int value = intent.getIntExtra("transfer",);

You can use the following in the calling/invoking activity "-

Intent intent = new Intent(this,CalledActivity.class);
        intent.putExtra(NameKeyforvalue,value); ......

startActivity(intent)

and use the following in Called/Invoked (receiving) activity :-

variabletoholdvalue = getIntent().getStringExtra(NameKeyforValue);

Note! getIntExtra, getLongExtra etc... (some require default, getStringExtra doesn't)
