android怎么在不同环境设置下选择不同的resource呢

android怎么在不同环境设置下选择不同的resource呢，例如，不同的语言设置，屏幕不同的方向，屏幕不同大小之类。

一般请况下我们会在那些resource folder 后面加上qualifiers，如果加两个或以上qualifiers，我们要按以下的顺序加

Table 15.1 Characteristics with configuration qualifiers

1. Mobilecountrycode(MCC),optionallyfollowedbymobilenetworkcode(MNC)
2. Language code, optionally followed by region code
3. Layout direction
4. Smallest width
5. Availablewidth
6. Availableheight
7. Screensize
8. Screenaspect
9. Screenorientation
10. UI mode
11. Night mode
12. Screen density (dpi)
13. Touchscreen type
14. Keyboard availability
15. Primary text input
16. Navigation key availability
17. Primary non-text navigation method
18. API level

You can find descriptions of these characteristics and examples of specific configuration qualifiers at http://developer.android.com/guide/topics/resources/providing-resources.html#AlternativeResources.

同样，android 系统在除掉了不合符的resource 后，就按上图的顺序的qualifier 去找到最合适的resource 来用了
