Android: 如何找到屏幕的宽度和高度?

Android: How to find width and height of screen?

我正在尝试查找屏幕的宽度和高度,但我尝试过的 none 方法将在我创建的 class 中起作用,我的代码如下。

有人知道怎么找吗?我不能使用我在下面尝试的方式,因为 .getWidth() 已被弃用?

public class Crate {

    public int acrossCrate;
    public int upDownCrate;
    Context theContext;

    WindowManager wm = (WindowManager)theContext.getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();
    int width = display.getWidth();


    public Crate() {
    acrossCrate = 650;
    upDownCrate = 650;
    //int width = ;
    //int height = ;

  }
 } 

使用下面的代码

private int getScreenHeight(Context context) {
        int height;

        if (android.os.Build.VERSION.SDK_INT >= 13) {
            WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            Display display = wm.getDefaultDisplay();
            Point size = new Point();
            display.getSize(size);
            height = size.y;
        } else {
            WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            Display display = wm.getDefaultDisplay();
            height = display.getHeight();  // deprecated
        }

        return height;
    }
