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);;


            }
        }
});

You can use the expandable list view explained in API demos to show groups

http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList1.html.

To animate the list items motion, you will have to override the getView method and apply translate animation on each list item. The values for animation depend on the position of each list item. This was something which i tried on a simple list view long time back.

You probably want to use an ExpandableListView, a special ListView that allows you to open and close groups.

Visibility change itself can be easy animated by overriding setVisibility method. Look at complete code:

public class SimpleViewAnimator extends FrameLayout
{
    private Animation inAnimation;
    private Animation outAnimation;

    public SimpleViewAnimator(Context context)
    {
        super(context);
    }

    public void setInAnimation(Animation inAnimation)
    {
        this.inAnimation = inAnimation;
    }

    public void setOutAnimation(Animation outAnimation)
    {
        this.outAnimation = outAnimation;
    }

    @Override
    public void setVisibility(int visibility)
    {
        if (getVisibility() != visibility)
        {
            if (visibility == VISIBLE)
            {
                if (inAnimation != null) startAnimation(inAnimation);
            }
            else if ((visibility == INVISIBLE) || (visibility == GONE))
            {
                if (outAnimation != null) startAnimation(outAnimation);
            }
        }

        super.setVisibility(visibility);
    }
}
