ViewPager animation fade in/out instead of slide

This should work better for the fade in/out transform:

public void transformPage(View view, float position) {    view.setTranslationX(view.getWidth() * -position);           if(position <= -1.0F || position >= 1.0F) {        view.setAlpha(0.0F);    } else if( position == 0.0F ) {        view.setAlpha(1.0F);    } else {         // position is between -1.0F & 0.0F OR 0.0F & 1.0F        view.setAlpha(1.0F - Math.abs(position));    }}

Based on a @murena's answer, this should work better for the fade in/out transform. At the end of animation the position is restored to default value.

public void transformPage(View view, float position) {    if(position <= -1.0F || position >= 1.0F) {        view.setTranslationX(view.getWidth() * position);        view.setAlpha(0.0F);    } else if( position == 0.0F ) {        view.setTranslationX(view.getWidth() * position);        view.setAlpha(1.0F);    } else {         // position is between -1.0F & 0.0F OR 0.0F & 1.0F        view.setTranslationX(view.getWidth() * -position);        view.setAlpha(1.0F - Math.abs(position));    }}  

Fade according to Google:https://developer.android.com/training/animation/reveal-or-hide-view

viewPager.setPageTransformer(false, new ViewPager.PageTransformer() {    @Override    public void transformPage(@NonNull View page, float position) {        page.setAlpha(0f);        page.setVisibility(View.VISIBLE);        // Start Animation for a short period of time        page.animate()            .alpha(1f)            .setDuration(page.getResources().getInteger(android.R.integer.config_shortAnimTime));    }});
