Android: how to call get method to display height and width?

Question

I have been trying to figure out how to find the height and width of the screen in android. i have found a way to get it but I dont know how to call the getScreenWidth and getScreenHeight to put values into my int height and int width?

public class Player {

public int across;
public int upDown;

public static int getScreenWidth(Context c) {
    DisplayMetrics dmetrics = new DisplayMetrics();
    ((Activity) c).getWindowManager().getDefaultDisplay()
            .getMetrics(dmetrics);
    return dmetrics.widthPixels;
}

// Get screen height
public static int getScreenHeight(Context c) {
    DisplayMetrics dmetrics = new DisplayMetrics();
    ((Activity) c).getWindowManager().getDefaultDisplay()
            .getMetrics(dmetrics);
    return dmetrics.heightPixels;
}

public Player() {

    int width = dmetrics.widthPixels;
    int height = dmetrics.heightPixels;
    int rectSide = 1000;

    //across = startPosX;
    //upDown = startPosY;

}

i am trying to get it by using int width = dmetric.widthPixels; but this obviously isnt the way to call the getScreenWidth. Im pretty bad at this stuff, so any help would be great.

If you are in an Activity when you wish to call these static methods you could call them this way:

int width = Player.getScreenWidth(this);
int height = Player.getScreenHeight(this);

If you're not in an activity you'll need to know one and pass it instead of this.

Also be aware that, because of the cast, if you pass something that is a Context but not an Activity it won't work and you won't know it until run time.
