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;
