Android的希伯来语（RTL）集成 [英] Android Hebrew (RTL) Integration
问题描述
我的工作相对简单的Android应用程序。我希望它有英文版本以及一个希伯来语版本。 （RTL从右到左对齐）
I'm working on a relatively simple Android app. I want it to have an English version as well as a Hebrew version. (RTL Right to Left Alignment)
我已经手动更改为右对齐布局的XML文件。当一个句子中包含数字（在它的中间），数字出现在镜子的看法： 29显示为92 21:45显示为54:12 和 2000显示为000,2
I have manually change the alignment to right in layout xml file. When a sentence contains digits (in the middle of it), the digits appear in a mirror view: 29 appears as 92, 21:45 appears as 54:12 and 2,000 appears as 000,2.
此外，当一个句子开始，数字或英文字母，他们抛出的句末搞乱了这一切。
Also, when a sentence starts with digits or English characters, they get thrown to the end of the sentence messing it all up.
我觉得对于Android版本4.0.3，它支持希伯来文。我有检查，在模拟器。
I think for android version 4.0.3 it supports Hebrew. I have check that in emulator.
因此，对于旧版本有没有实现希伯来语正确的方法是什么？ 请大家帮帮忙。
So for older versions is there correct way to implement Hebrew? Please help.
推荐答案
我觉得Android的比迪烟的分析算法有一定的缺陷。统一code有两个无形的，强烈的方向性特征，这可能有助于这些问题：
I think that Android's bidi analysis algorithm has some flaws. Unicode has two invisible, strongly directional characters that might help with these problems:
- U + 200E - 左到右标记
- U + 200F - 从右到左标记
有关数字顺序的问题，可以尝试在左到右标记（U + 200E）的数字序列的两侧。
For the digit order problem, try putting left-to-right marks (U+200E) on both sides of the digit sequence.
统一code还具有以下的比迪烟格式codeS：
Unicode also has the following bidi formatting codes:
- U + 202A - 左到右嵌入
- U + 202B - 从右到左嵌入
- U + 202C - 弹出方向格式（取消previous嵌套或优先）
- U + 202D - 左到右覆盖
- U + 202E - 从右到左的优先
有关在希伯来文英文碎片的问题，它可能是简单，只要把一个从右到左标记的英语了。 （Android的算法可以根据该段是左到右以来的第一个字符是英文的IM pression）。如果不工作，也许尝试使用格式codeS的组合周围选定的文本。 （我想尝试左到右包埋随后弹出方向格式。我也想尝试从右到左周围的事物结合选择性明确从右至左嵌入嵌入。）
For the problem with English fragments in Hebrew text, it might be as simple as putting a right-to-left mark before the English. (Android's algorithm may be under the impression that the paragraph is left-to-right since the first characters are English.) If that doesn't work, perhaps try surrounding selected text with some combination of formatting codes. (I'd try left-to-right embedding followed by pop directional formatting. I'd also try right-to-left embedding around everything combined with selective explicit right-to-left embeddings.)
的方式，这些都应该影响文本排版用C双向算法的统一code标准附件＃9 。但是，如果Android的实施被打破（我怀疑它），最好你能做的就是尝试和错误，直到你把事情看的权利。祝你好运。
The way these are supposed to affect text layout are defined by the Unicode Bidirectional Algorithm Unicode Standard Annex #9. However, if Android's implementation is broken (and I suspect it is), the best you can do is trial-and-error until you get things looking right. Good luck.
修改
据code而言，这里有怎么可能用Java做一个例子：
As far as code is concerned, here's an example of how it might be done in Java:
String text = "גרסה \u200e2.100\u200e זמינה";
在XML中，它可能是：
In XML, it might be:
<string name="update_available">גרסה ‎2.100‎ זמינה</string>
