This code able to convert the whole view in scrollview to images. It been tested and successfully working.

SampleActivity.java

@BindView(R.id.native_resit)
protected ScrollView native_resit;


@Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        ....
        ....

        print_resit.setOnClickListener(new resitClickListener());

        runRecieptData();
}

private class resitClickListener implements View.OnClickListener{
        @Override
        public void onClick(View view) {
            if (view.getId() == R.id.close_btn){
                getFragmentManager().popBackStack();
            }
            else if (view.getId() == R.id.print_resit){
                print();
            }
        }
}
