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;
