Change DialogFragment size according to Android screen

Navigation
1

I have a very simple registration form that appears when I click a button to register. This form appears in DialogFragment , however, with a very small size.
Zonzando on the internet I found a code that changes the size of it: 


  @Override
  public void onStart() {
        super.onStart();


    if (getDialog() == null)
        return;

    int dialogWidth = 200;
    int dialogHeight = 400;

    getDialog().getWindow().setLayout(dialogWidth, dialogHeight);

 } 




 
 



But it seems that it defines these values in pixels, so I wanted to know if there is a way to calculate the width of the screen (or view I do not know) and set the width to 80% of the screen and let the height increase automatically.


Note: I'm a little confused by my words but I can understand my purpose with this question, if you do not understand, just make a comment that I explain in more detail.

A solution can be to take the dimensions of the device's screen. 

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int largura = size.x;
int altura = size.y;

And from there, perform the calculation for the height / width of your Dialog. 

larguraDoSeuDialog = largura * 0.8;
alturadoSeuDialog = altura * 0.8;

Note: The Context above would be an instance of your activity, if you are running the process inside it, it may be this, otherwise you will have to pass the parameter.
