获取状态栏的高度。

     private static int statusBarHeight;

     private int getStatusBarHeight() {
         if (statusBarHeight == 0) {
             try {
                 Class<?> c = Class.forName("com.android.internal.R$dimen");
                 Object o = c.newInstance();
                 Field field = c.getField("status_bar_height");
                 int x = (Integer) field.get(o);
                 statusBarHeight = getResources().getDimensionPixelSize(x);
             } catch (Exception e) {
                 e.printStackTrace();
             }
         }
         return statusBarHeight;
     }

获取屏幕的宽和高

方法一：

         WindowManager mWm = (WindowManager) getSystemService(WINDOW_SERVICE);
         int screenWidth = mWm.getDefaultDisplay().getWidth();
         int screenHeight = mWm.getDefaultDisplay().getHeight();

注意：getWidth()和getHeight()方法已经过时

方法二：

         WindowManager mWm = (WindowManager) getSystemService(WINDOW_SERVICE);
         Point point= new Point();
         mWm.getDefaultDisplay().getRealSize(point);
         int screenWidth=point.x;
         int screenHeight=point.y;
