我尝试了所有可能的“解决方案”，但都失败了，我注意到Elliott Hughes的“Dalvik Explorer”应用程序在任何Android设备/操作系统版本上都始终显示正确的维度。我最后看了他的开源项目，可以在这里找到：https://code.google.com/p/enh/

以下是所有相关代码：

WindowManager w = activity.getWindowManager();
Display d = w.getDefaultDisplay();
DisplayMetrics metrics = new DisplayMetrics();
d.getMetrics(metrics);
// since SDK_INT = 1;
widthPixels = metrics.widthPixels;
heightPixels = metrics.heightPixels;
try {
    // used when 17 > SDK_INT >= 14; includes window decorations (statusbar bar/menu bar)
    widthPixels = (Integer) Display.class.getMethod("getRawWidth").invoke(d);
    heightPixels = (Integer) Display.class.getMethod("getRawHeight").invoke(d);
} catch (Exception ignored) {
}
try {
    // used when SDK_INT >= 17; includes window decorations (statusbar bar/menu bar)
    Point realSize = new Point();
    Display.class.getMethod("getRealSize", Point.class).invoke(d, realSize);
    widthPixels = realSize.x;
    heightPixels = realSize.y;
} catch (Exception ignored) {
}

EDIT：略有改进的版本（避免在不受支持的OS版本上触发异常）：

WindowManager w = activity.getWindowManager();
Display d = w.getDefaultDisplay();
DisplayMetrics metrics = new DisplayMetrics();
d.getMetrics(metrics);
// since SDK_INT = 1;
widthPixels = metrics.widthPixels;
heightPixels = metrics.heightPixels;
// includes window decorations (statusbar bar/menu bar)
if (Build.VERSION.SDK_INT >= 14 && Build.VERSION.SDK_INT < 17)
try {
    widthPixels = (Integer) Display.class.getMethod("getRawWidth").invoke(d);
    heightPixels = (Integer) Display.class.getMethod("getRawHeight").invoke(d);
} catch (Exception ignored) {
}
// includes window decorations (statusbar bar/menu bar)
if (Build.VERSION.SDK_INT >= 17)
try {
    Point realSize = new Point();
    Display.class.getMethod("getRealSize", Point.class).invoke(d, realSize);
    widthPixels = realSize.x;
    heightPixels = realSize.y;
} catch (Exception ignored) {
}

简单的功能与较低版本兼容。

/**
 * @return screen size int[width, height]
 *
 * */
public int[] getScreenSize(){
    Point size = new Point();
    WindowManager w = getWindowManager();

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2){
        w.getDefaultDisplay().getSize(size);
        return new int[]{size.x, size.y};
    }else{
        Display d = w.getDefaultDisplay();
        //noinspection deprecation
        return new int[]{d.getWidth(), d.getHeight()};
    }
}

要使用：

int width = getScreenSize()[0];
int height = getScreenSize()[1];

有一种使用DisplayMetrics（API 1）来实现这一点的方法并不过时，它可以避免try/catch混乱：

 // initialize the DisplayMetrics object
 DisplayMetrics deviceDisplayMetrics = new DisplayMetrics();

 // populate the DisplayMetrics object with the display characteristics
 getWindowManager().getDefaultDisplay().getMetrics(deviceDisplayMetrics);

 // get the width and height
 screenWidth = deviceDisplayMetrics.widthPixels;
 screenHeight = deviceDisplayMetrics.heightPixels;

最简单的方法：

 int screenHeight = getResources().getDisplayMetrics().heightPixels;
 int screenWidth = getResources().getDisplayMetrics().widthPixels; 

科特林

fun getScreenHeight(activity: Activity): Int {
    val metrics = DisplayMetrics()
    activity.windowManager.defaultDisplay.getMetrics(metrics)
    return metrics.heightPixels
}

fun getScreenWidth(activity: Activity): Int {
    val metrics = DisplayMetrics()
    activity.windowManager.defaultDisplay.getMetrics(metrics)
    return metrics.widthPixels
}

如果Display类不工作，则上面的答案将不起作用，那么您可以通过下面的方法获得宽度和高度。

private static final int WIDTH_INDEX = 0;
private static final int HEIGHT_INDEX = 1;

    public static int[] getScreenSize(Context context) {
        int[] widthHeight = new int[2];
        widthHeight[WIDTH_INDEX] = 0;
        widthHeight[HEIGHT_INDEX] = 0;

        try {
            WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            Display display = windowManager.getDefaultDisplay();

            Point size = new Point();
            display.getSize(size);
            widthHeight[WIDTH_INDEX] = size.x;
            widthHeight[HEIGHT_INDEX] = size.y;

            if (!isScreenSizeRetrieved(widthHeight))
            {
                DisplayMetrics metrics = new DisplayMetrics();
                display.getMetrics(metrics);
                widthHeight[0] = metrics.widthPixels;
                widthHeight[1] = metrics.heightPixels;
            }

            // Last defense. Use deprecated API that was introduced in lower than API 13
            if (!isScreenSizeRetrieved(widthHeight)) {
                widthHeight[0] = display.getWidth(); // deprecated
                widthHeight[1] = display.getHeight(); // deprecated
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        return widthHeight;
    }

    private static boolean isScreenSizeRetrieved(int[] widthHeight) {
        return widthHeight[WIDTH_INDEX] != 0 && widthHeight[HEIGHT_INDEX] != 0;
    }
