所以我有一个小问题，我正在写这需要屏幕宽度发送到服务器的功能。我得到了这一切的工作，我用：

So i have a small problem, i'm writing a function which need to send screen width to server. I got it all to work, and i use:

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();

获得宽度。然而.getWidht（）函数去precated，它说你需要使用：

to get width. However .getWidht() function is deprecated and it says u need to use:

Point size = new Point();
display.getSize(size);

不过，该功能仅avaible的API级别13以上，我最小的SDK是8。所以，我该怎么办？它是安全的，如果我留在的getWidth？为什么要增加新的功能，而不是让他们向后兼容？

But that function is only avaible for api level 13 or more, and my minimum sdk is 8. So what can i do? Is it safe if i stay with getWidth? Why adding new function and not make them backward compatible?

推荐答案

可能是这种方式会有所帮助：

May be this approach will be helpful:

DisplayMetrics displaymetrics = new DisplayMetrics();
mContext.getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int screenWidth = displaymetrics.widthPixels;
int screenHeight = displaymetrics.heightPixels;
