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: http://stackoverflow.com/questions/2634073/how-do-i-animate-view-setvisibilitygone/3952933#3952933

Does this assure that when you show something that is GONE it will expand and pushes everything bellow too?
