@Override
        protected void onPostExecute(Drawable result) {
            Log.d("width",""+result.getIntrinsicWidth());
            urlDrawable.setBounds(0, 0, 0+result.getIntrinsicWidth(), 600);

            // change the reference of the current drawable to the result
            // from the HTTP call
            urlDrawable.drawable = result;

            // redraw the image by invalidating the container
            URLImageParser.this.container.invalidate();

            // For ICS
            URLImageParser.this.container.setHeight((400+URLImageParser.this.container.getHeight()
                    + result.getIntrinsicHeight()));

            // Pre ICS`enter code here`
            URLImageParser.this.container.setEllipsize(null);
        }

DisplayMetrics lDisplayMetrics = getResources().getDisplayMetrics();
int widthPixels = lDisplayMetrics.widthPixels;
int heightPixels = lDisplayMetrics.heightPixels;

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;
    }

@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
  public static double getHeight() {
    DisplayMetrics displayMetrics = new DisplayMetrics();
    WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();
    display.getRealMetrics(displayMetrics);

    //int height = displayMetrics.heightPixels;
    //int width = displayMetrics.widthPixels;
    return displayMetrics.heightPixels;
  }

使用这种方法你可以得到屏幕高度。 如果你想要宽度改变displayMetrics。hightpixels到displayMetrics.widthPixels。

它还包括所需的api构建版本。

屏幕分辨率是屏幕中像素的总和。下面的程序将提取设备的屏幕分辨率。它将打印屏幕的宽度和高度。这些值以像素为单位。

public static Point getScreenResolution(Context context) {
// get window managers
WindowManager manager =  (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);
Display display = manager.getDefaultDisplay();
Point point = new Point();
display.getSize(point);

 // get width and height
 int width = point.x;
 int height = point.y;

 return point;

}

       @Override
        protected void onPostExecute(Drawable result) {
            Log.d("width",""+result.getIntrinsicWidth());
            urlDrawable.setBounds(0, 0, 0+result.getIntrinsicWidth(), 600);

            // change the reference of the current drawable to the result
            // from the HTTP call
            urlDrawable.drawable = result;

            // redraw the image by invalidating the container
            URLImageParser.this.container.invalidate();

            // For ICS
            URLImageParser.this.container.setHeight((400+URLImageParser.this.container.getHeight()
                    + result.getIntrinsicHeight()));

            // Pre ICS`enter code here`
            URLImageParser.this.container.setEllipsize(null);
        }
