Answer 1

if you want to inflate views in pager you must have to implement two methods. instantiateItem and destroyItem

public class DialogPagerAdapter extends PagerAdapter {

    private Context mContext;

    //view inflating..
    @Override
    public Object instantiateItem(ViewGroup collection, int position) {
        LayoutInflater inflater = LayoutInflater.from(mContext);
        ViewGroup layout = (ViewGroup) inflater.inflate(R.layout.account_dialog_signin_viewpagers,
                collection, false);

        TextView tvLabel = (TextView) layout.findViewById(R.id.textView);
        switch (position) {
            case 0:
                tvLabel.setText("Log In");
                tvLabel.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                    }
                });
                break;
            case 1:
                tvLabel.setText("Sign Up");
                tvLabel.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                    }
                });
                break;
            case 2:
                tvLabel.setText("Send Reset Link");
                tvLabel.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        //onOptionClickForgot.OnOptionClick();
                    }
                });
                break;
        }

        collection.addView(layout);
        return layout;
    }

    @Override
    public void destroyItem(ViewGroup collection, int position, Object view) {
        collection.removeView((View) view);
}

    @Override
    public int getCount() {
        return 3;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }
}

Simply call it like

viewPager.setAdapter(new DialogPagerAdapter);
