Android的多屏幕支持 [英] Android multiple screen support

问题描述

我感到困惑Android的多屏幕支持。 http://developer.android.com/guide/practices/screens_support.html 我读了这篇文章，但仍然事情不清楚我。

I am confused about android's multiple screen support. http://developer.android.com/guide/practices/screens_support.html I read this article, but still something is not clear for me.

• 我用DP代替PX在我的布局


• 我把高，中，图像以绘制资源目录的低版本的。

我在依照本条这改变。但在一些密度下，仍然存在问题，尽管其中一些工作得很好。

I made this changes according to this article. But in some densities, there is still problem although some of them work very well.

问题是，什么是多款Android的屏幕类型的确切宽度和高度dp为单位。如果是多变，PX之​​间的区别是什么呢？

The question is what is the exact width and height in dp units for variety of android screen types. if it is changeable, what is the difference between px?

• PX多变，DP多变太？有什么区别？

如果改变能改变的，我应该更改视图对每个屏幕dentisies创建功能或创建单独的布局，宽度和高度由code？请给一个方式来理解这个...

if changeable, should I change the view's width and height by code on Create function or create seperate layouts for each screen dentisies? Please give a way to understand this...

在此先感谢..

推荐答案

PX是一个固定的措施。这意味着，如果100像素的小屏幕上占据屏幕的1/2，它会占用大屏幕上要少得多。 DP =密度（独立的）的像素，基于该装置的densitity。所以，如果你指定一个宽度50dp在小屏幕上，这将扩大在大屏幕上。需要注意的是DP是不是在所有设备上的布局保持兼容的保险，因为设备具有不同的纵横比。要构建一个完美的布局，看起来一模一样上的所有设备，必须使用更多的技术。 LinearLayout中，您可以分配权重。考虑这样做。 http://developerlife.com/tutorials/?p=312

px is a fixed measure. This means that if 100px on a small screen take up 1/2 of the screen, it will take up much less on a large screen. dp = density (independent) pixels, is based on the densitity of the device. So if you specify a width to 50dp on a small screen, it will expand on a large screen. Note that dp is not an insurance of layout compability on all devices, since devices have different aspect ratios. To build a perfect layout, that looks exactly the same on all devices, you must use more techniques. Linearlayout allows you to assign weights. Look into that. http://developerlife.com/tutorials/?p=312
