由于getMetrics和getRealMetrics已弃用，谷歌建议按如下方式确定屏幕宽度和高度:

WindowMetrics windowMetrics = getActivity().getWindowManager().getMaximumWindowMetrics();
Rect bounds = windowMetrics.getBounds();
int widthPixels = bounds.width();
int heightPixels = bounds.height();

然而，我想出了另一种方法，给我同样的结果:

Configuration configuration = mContext.getResources().getConfiguration();
Display.Mode mode = display.getMode();
int widthPixels = mode.getPhysicalWidth();
int heightPixels = mode.getPhysicalHeight();

你可以从上下文中获得宽度和高度

java:

  int width= context.getResources().getDisplayMetrics().widthPixels;
  int height= context.getResources().getDisplayMetrics().heightPixels;

科特林

    val width: Int = context.resources.displayMetrics.widthPixels
    val height: Int = context.resources.displayMetrics.heightPixels

这里显示的方法已弃用/过时，但仍然可以工作。需要API 13

看看吧

Display disp= getWindowManager().getDefaultDisplay();
Point dimensions = new Point();
disp.getSize(size);
int width = size.x;
int height = size.y;

试试下面的代码:-

1.

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

2.

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();  // deprecated
int height = display.getHeight();  // deprecated

or

int width = getWindowManager().getDefaultDisplay().getWidth(); 
int height = getWindowManager().getDefaultDisplay().getHeight();

3.

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);

metrics.heightPixels;
metrics.widthPixels;

我使用下面的代码来获取屏幕尺寸

getWindow().getDecorView().getWidth()
getWindow().getDecorView().getHeight()

有一个非常简单的答案，没有通过上下文

public static int getScreenWidth() {
    return Resources.getSystem().getDisplayMetrics().widthPixels;
}

public static int getScreenHeight() {
    return Resources.getSystem().getDisplayMetrics().heightPixels;
}

注:如果你想要高度包括导航条，使用下面的方法

WindowManager windowManager =
        (WindowManager) BaseApplication.getApplication().getSystemService(Context.WINDOW_SERVICE);
    final Display display = windowManager.getDefaultDisplay();
    Point outPoint = new Point();
    if (Build.VERSION.SDK_INT >= 19) {
        // include navigation bar
        display.getRealSize(outPoint);
    } else {
        // exclude navigation bar
        display.getSize(outPoint);
    }
    if (outPoint.y > outPoint.x) {
        mRealSizeHeight = outPoint.y;
        mRealSizeWidth = outPoint.x;
    } else {
        mRealSizeHeight = outPoint.x;
        mRealSizeWidth = outPoint.y;
    }
