获取屏幕尺寸桶编程？ [英] Get screen size bucket programatically?

问题描述

我要确定当前设备是否具有小型，中型，大型或XLARGE在code屏幕。我无法在SDK文档，这将有助于我得到的信息任何事情。所有方法/班我已经看过仅提供绝对的值（即屏幕大小像素，屏幕像素密度，等等）。

有没有办法告诉什么样的屏幕，我在code运行？

解决方案

我结束了使用布尔放置在不同的文件夹桶资源

。我只需要正常（小/中）和大（大/ XLARGE）画面之间进行区分，所以我这样做：

值/ bools.xml

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;资源＆GT;
    ＆LT;布尔名=screen_large＆GT;假＆LT; /布尔＆GT;
＆LT; /资源＆GT;
 

价值观大/ bools.xml

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;资源＆GT;
    ＆LT;布尔名=screen_large＆GT;真＆LT; /布尔＆GT;
＆LT; /资源＆GT;
 

然后，我只是叫<一href="http://developer.android.com/reference/android/content/res/Resources.html#getBoolean%28int%29"><$c$c>getBoolean(R.bool.screen_large)告诉屏幕是大还是不行。这种方式是100％到平台决定什么屏幕的设备了。

I want to determine whether the current device has a small, medium, large or xlarge screen in code. I can't find anything in the SDK docs that would help me get to that information. All the methods / classes I have looked at provide only absolute values (i.e. screen size in pixels, screen density, etc.).

Is there a way to tell what kind of screen I'm running on in code?

解决方案

I ended up using bool resources placed in the different bucket folders. I only needed to differentiate between normal (small / medium) and large (large / xlarge) screens, so I did this:

values/bools.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="screen_large">false</bool>
</resources>

values-large/bools.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="screen_large">true</bool>
</resources>

Then, I just call getBoolean(R.bool.screen_large) to tell whether the screen is large or not. This way it's 100% up to the platform decide what screen the device has.
