Technically you should not place a scrollable view inside a scrollable view. This means, you cannot put RecyclerView inside ScrollView.

Here is the correct xml for my problem:

and for recycler view to allow scroll with other items of scrollView , we have to give recyclerView height at runtime by setting its LayoutParams. Like for 100 TextView of 50dp each, the recyclerView Height will be:

mRecyclerView = (RecyclerView) findViewById(R.id.mRecycler);        float density = getResources().getDisplayMetrics().density;      mRecyclerView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, ((int) (density * 50)) * 100));  

It will work fine :)
