问题描述
我问过一个类似的问题，但想到我会问一个更普遍的问题得到更广泛的投入。
I've asked a question similar to this but thought I would ask a more general question to get a wider range of input.
我问这个问题，因为我已经开发了近两年的应用程序，我把所有的图像资源，绘制，华电国际文件夹中，没有处理好风景模式，测试它主要是对我个人的Droid手机，基本上觉得我是只开发自己的设备。我虽然一直使用的DPI和SP在适当的地方，这是不够的，我的应用程序，以适当的比例在其他屏幕尺寸/密度。它缩放没关系有时，但总是趋于切断屏幕的一部分上较小的尺寸。
I ask this question because the last two apps I've developed, I threw all image resources in the drawable-hdpi folder, didn't deal with landscape-mode, tested it mainly on my own personal Droid phone, and basically felt like I was only developing for my own device. Although I did always use dpi and sp in the appropriate places, this was not enough for my app to scale appropriately on other screen sizes/densities. It scaled okay sometimes, but would always tend to cut off a portion of the screen on smaller sizes.
什么是开始一个应用程序，将规模至少在某种程度上也对所有设备的最佳方法是什么？
What are the best ways to begin an app that will scale at least somewhat well on all devices?
例如，我要建立我的应用程序的布局，使它看起来默认的HVGA屏幕上正确，并允许它扩展到更大的密度？难道是一个最佳实践，积极构建纵向和横向布局文件？
For example, should I construct my app layouts so that it looks correct on the default HVGA screen and allow it to scale to larger densities? Would it be a best practice to be actively building both portrait and landscape layout files?
你在做什么，以确保您的应用程序看起来不错，在所有设备上，而不只是专注在一个尺寸，然后争先恐后稍后左右的管理呢？
What are you doing to ensure your apps look nice on all devices without just focusing on one size and then scrambling around later to manage this?
推荐答案
我公司始终遵循这些规则：
I always follow those rules:
- 设置一切从支持屏来真。 Android将知道你是准备好每一个屏幕环境中，你就会知道，它没有任何屏幕虚拟化。例如：即使您的设备具有大尺寸屏幕，你的code会看到它作为一个正常大小的屏幕
- 请不要使用固定大小的宽度和高度。如果你必须使用DP作为虚拟像素。使用WRAP_CONTENT和FILL_PARENT。 DP是在屏幕上用160dpi的物理像素。如果您的应用程序在设备低/高密度运行，Android将重新计算这个给你。
- 使用DP为单位的字体大小。
- 尝试相对做的一切。 U可以使用RelativeLayout的，如果你想有等，如果你需要的百分比，你可以使用的LinearLayout下的另一种东西。
- 使用九pathes作为背景。
- 确保你把资源投入到正确的绘制/布局文件夹。
- set everything from supports-screens to true. Android will know that you are ready for every screen environment and you will know that it doesn't make any screen virtualization. For example: even if your device has big-size screen, your code will see it as a normal-size screen
- don't use fixed sizes for width and height. If you must, use "dp" as a virtual pixel. use WRAP_CONTENT and FILL_PARENT. "dp" is a physical pixel on screen with 160 dpi. If your app runs on device with lower/higher density, android will recalculate this for you.
- use "dp" as a unit for font size.
- try to do everything relatively. U can use RelativeLayout if you want to have "something under another" etc. If you need percentages you can use LinearLayout.
- use nine-pathes as a background.
- make sure that you put resources into correct drawable/layout folders.
关 - 当然，这并不是每一个项目最好的方法:)有时UI设计者希望一些额外的：]
Off-course, this is not best approach for every project :) Sometimes UI designer wants some extra :]
