And here's the java code that calls the button event:

final ToggleButton bt=(ToggleButton) findViewById(R.id.mostrar);


    bt.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            if (bt.isChecked()) {

                /*TranslateAnimation slide = new TranslateAnimation(0, 0, 0,
                          -findViewById(R.id.informgeral).getHeight()*2);
                           slide.setDuration(500);
                           slide.setFillAfter(true);
                           findViewById(R.id.informgeral).startAnimation(slide);*/

                findViewById(R.id.informgeral).setVisibility(View.VISIBLE);;

            } else {

            /*  TranslateAnimation slide = new TranslateAnimation(0, 0, 0,
                          findViewById(R.id.informgeral).getHeight());
                           slide.setDuration(500);
                           slide.setFillAfter(true);
                           findViewById(R.id.informgeral).startAnimation(slide);*/


                           //findViewById(R.id.listBut).startAnimation(slide);


                findViewById(R.id.informgeral).setVisibility(View.GONE);;


            }
        }
});

There is no easy way to animate hiding/showing views. You can try method described in following answer: How do I animate View.setVisibility(GONE)

Well there is a very easy way, but just setting android:animateLayoutChanges="true" will not work. You need to enableTransitionType in you activity. Check this link for more info: http://www.thecodecity.com/2018/03/android-animation-on-view-visibility.html

Like tomash said before: There's no easy way.

You might want to take a look at my answer here.
It explains how to realize a sliding (dimension changing) view.
In this case it was a left and right view: Left expanding, right disappearing.
It's might not do exactly what you need but with inventive spirit you can make it work ;)

To animate layout changes, you can add the following attribute to your LinearLayout

android:animateLayoutChanges="true"

and it will animate changes automatically for you.

For information, if android:animateLayoutChanges="true" is used, then custom animation via anim xml will not work.

If anyone else is strugelling with this in the present, here is a much easier version:

It is possible to set a property of the parent layout in the XML: 

android:animateLayoutChanges="true"

This will animate views when they are added/removed.
Keep a reference to the view and reinsert it at its proper index and you're gold.

This is a quite old question, still comments show, that still people have problems, so here is my solution with following additional features:

  • adjust the animation (speed, type, ...)
  • does not need to extend any class
  • in my case, animateLayoutChanges has problems in the new CoordinatorLayout

Function - Example (I have this function in an utility class)

public static void animateViewVisibility(final View view, final int visibility)
{
    // cancel runnning animations and remove and listeners
    view.animate().cancel();
    view.animate().setListener(null);

    // animate making view visible
    if (visibility == View.VISIBLE)
    {
        view.animate().alpha(1f).start();
        view.setVisibility(View.VISIBLE);
    }
    // animate making view hidden (HIDDEN or INVISIBLE)
    else
    {
        view.animate().setListener(new AnimatorListenerAdapter()
        {
            @Override
            public void onAnimationEnd(Animator animation)
            {
                view.setVisibility(visibility);
            }
        }).alpha(0f).start();
    }
}

Adjust animation

After calling view.animate() you can adjust the animation to whatever you want (set duration, set interpolator and more...). You may as well hide a view by scaling it instead of adjusting it's alpha value, just replace the alpha(...) with scaleX(...) or scaleY(...) in the utility method if you want that
