Android - button random position weird behavior

So I'm trying to appear 3 buttons on a random position. First im giving them a random position based on the screen size using this code:

    float x = new Random().nextInt(metrics.widthPixels / 2);
    float y = new Random().nextInt(metrics.heightPixels / 2);
    lbutton1.setX(x);
    lbutton1.setY(y);
    float x1 = new Random().nextInt(metrics.widthPixels / 2);
    float y1 = new Random().nextInt(metrics.heightPixels / 2);
    lbutton2.setX(x1);
    lbutton2.setY(y1);
    float x2 = new Random().nextInt(metrics.widthPixels / 2);
    float y2 = new Random().nextInt(metrics.heightPixels / 2);
    lbutton3.setX(x2);
    lbutton3.setY(y2);

Buttons at this point are set GONE in .xml file. When I trying to call their method so they become VISIBLE im doing it with using this code:

    lbutton1.setVisibility(View.VISIBLE);
    lbutton2.setVisibility(View.VISIBLE);
    lbutton3.setVisibility(View.VISIBLE);

Problem is that while button1 appears in the position set by setX(x),setY(y), the other 2 buttons X position (from what i can tell) does not take the value of x1,x2 but it takes random values that I cant explain where they are taken from. All buttons Y position is ok.. Any ideas why could this be happening?
