Click one button and make another appear

Question

How do I click on botao1 and do the botao2 and botao3 appear on the screen? I left the botao2 and the botao3 visibility = invisible.

Answer 1

This is simple to do, just use the onClick of botao1 to make others appear?

botao1.setOnClickListener( new OnClickListener( ) 
{
    @Override
    public void onClick( View v ) 
    {
         botao1.setVisibility( View.GONE    );  //desaparece o 1
         botao2.setVisibility( View.VISIBLE );  //aparece o 2 
         botao3.setVisibility( View.VISIBLE );  //aparece o 3
    }
});
