How to make the text direction from right to left
提问by Adham
I want to write text in (right to left language i.e. Arabic) in a TextView. But I want to make the text writing direction from right to left. gravity:rightwill align the text to right only. I want to justify the text from right to left ( to make the words and numbers appear in he entered order in the line ) . how ?
我想在 TextView 中用（从右到左的语言，即阿拉伯语）编写文本。但我想让文字书写方向从右到左。gravity:right将仅将文本向右对齐。我想从右到左对齐文本（使单词和数字按他在行中输入的顺序出现）。如何 ？

Another clever way which can be used in older versions of android and can be used anywhere in string so it's handier even in latest version of android, is to include the right-to-left markor even left-to-right markin the string when it's needed:
可在旧版本的Android的使用，可以在字符串中使用任何地方，所以它的使用方便性，即使在Android的最新版本，是包含另一种巧妙的方式从右到左标记，甚至左至右符号的字符串需要时：
left-to-right mark: ‎ or ‎ (U+200E)
right-to-left mark: ‏ or ‏ (U+200F)
This is how it's down:
这是它的下降方式：
String rtl = "Hello \u200F(????)";
The good thing about this method is you can even use it after punctuation like (,{,[,!which are positioned right incorrectly! examples:
这个方法的好处是你甚至可以在像 (,{,[,!这样定位不正确的标点符号之后使用它！示例：
????! // wrong position
????!? // right position by adding RLM after !
look how !is positioned correctly in second line, actually there is an RLM after it, and you can copy paste it even if it's invisible.
看看怎么样！正确定位在第二行，实际上它后面有一个RLM，即使它不可见，您也可以复制粘贴它。
The second good thing as you saw it is that you can use this method (these char codes) in any system that supports RTL like browsers, word and so on.
正如您所见，第二件好事是您可以在任何支持 RTL 的系统（如浏览器、word 等）中使用此方法（这些字符代码）。

Just put this property in your TextView and everything will workout just fine it will automatically detect your text and change accordingly
只需将此属性放在您的 TextView 中，一切都会好起来的，它会自动检测您的文本并相应地更改

By using attributes as below in my xml code strangely I got a right to left text with correct punctuation. But this is not a perfect solution for multi language text:
通过在我的 xml 代码中使用如下属性，我奇怪地得到了一个带有正确标点符号的从右到左的文本。但这不是多语言文本的完美解决方案：
android:textDirection="ltr"
android:gravity="right"
setting ltr corrects punctuation problems like having dot on right side instead of left.
设置 ltr 可以纠正标点符号问题，例如在右侧而不是左侧有点。
gravity attribute makes text flow from right to left.
重力属性使文本从右向左流动。
