Android：如何调用get方法显示高度和宽度？

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.

I know, really what im asking is how do i call this get method i have created to set values for width and height? – Phill

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.
