Android Button Set Button Invisible Without Click

Question

This seems like a very simple problem, but for some reason I find myself unable to find any suitable answers that work. What I have is 2 buttons with one stacked on the other in a Frame Layout, and when Button1 is clicked, it becomes invisible and Button2 appears. What I'm trying to get to happen is after a few seconds Button2 automatically becomes invisible and Button1 is visible again. Here is the little bit of code I have. Any help would be greatly appreciated!

button1 = (Button)findViewById(R.id.button1);
button2 = (Button)findViewById(R.id.button2);


        button1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub 

                button1.setVisibility(Button.GONE);
                button2.setVisibility(Button.VISIBLE);

            }
        });

Answer 1

A simpler solution than many that are being proposed here would be as follows:

button1 = (Button)findViewById(R.id.button1);
button2 = (Button)findViewById(R.id.button2);


button1.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        button1.setVisibility(Button.GONE);
        button2.setVisibility(Button.VISIBLE);
        button1.postDelayed(new Runnable() {
            @Override
            public void run() {
                button1.setVisibility(View.VISIBLE);
                button2.setVisibility(View.GONE);
            }
        }, 2000);
    }
});
