Android установка с TextView справа налево

Question

мне нужно установить текст в Android TextView, который в сочетании с арабскими буквами и в середине у меня есть 123.doc

В strings.xml:

<string name="message">حفظ باسم 1% وإرسال</string> 

(в переводе на «Сохранить как 123.doc и отправить»)

а потом в коде:

String string = getString(R.string.message); 
String message = string.replace("%1", "123.doc"); 

Выход неправильно:
حفظ باسم doc.123 وإرسال
(должно быть 123.doc)

Я попытался установить текст тяжести, выравнивание текста и то, что было предложено здесь: Android setting with TextView for Hebrew text? без помощи ...

Может ли кто-нибудь помочь?
Thanx так много!

Update:
Вот изображение моего кода, предложенного ответ Фархада Faghihi и выход (Не возражает значение строки, я просто добавил случайное слово для тестирования):

Answer 1

Так что я, наконец, нашел способ получить это право! В случае, если кто-то хочет знать, это то, как (это так просто, я не могу поверить, что никто не предлагал раньше):

String filename = 123.doc 
String message = s1 + "\u202A" + fileName + "\u202C" + s2; 

Где s1 и s2 являются строками в языке РТЛ.

Answer 2

Существуют библиотеки, которые можно использовать для переформатирования текстов с неязыковых языков.

Возможно, вы захотите взглянуть на «Лучше арабский решайер» на github.

, а также, поскольку у меня были проекты, которые касались отображения арабского и персидского текста (оба имеют 29 букв алфавита AFAIK), я использовал очень удобную библиотеку под названием Farsi.java.

Этот класс имеет два основных метода:

1- Преобразовать (строка) - переформатирует простой текст арабский/персидский

2- ConvertBackToRealFarsi (строка) - переформатирует простой текст арабский/персидский, который объединяется с пунктуационными знаками, числами, английскими буквами, ....

Поскольку арабский алфавит имеет меньше букв алфавита, чем персидский, вы можете использовать эту библиотеку плавно.

код:

package com.example.fasri; 

import android.content.Context; 
import android.graphics.Typeface; 

public final class Farsi { 

public static boolean isFarsiConversionNeeded = true; 

private final static String szLamAndAlef = Character 
     .toString((char) 0xfedf) 
     + Character.toString((char) 0xfe8e); // Lam + Alef 

private final static String szLamStickAndAlef = Character 
     .toString((char) 0xfee0) 
     + Character.toString((char) 0xfe8e); // Lam (Sticky !!!)+ 
               // Alef 

private final static String szLa = Character.toString((char) 0xfefb); // La 
private final static String szLaStick = Character.toString((char) 0xfefc); // La 
                      // (Sticky!!!) 

private final static String szLamAndAlefWoosim = Character 
     .toString((char) 0xe1) 
     + Character.toString((char) 0xbb); // Lam + Alef 

private final static String szLamStickAndAlefWoosim = Character 
     .toString((char) 0x90) 
     + Character.toString((char) 0xbb); // Lam (Sticky !!!)+ 
              // Alef 

private final static String szLaWoosim = Character.toString((char) 0xd9); // La 
private final static String szLaStickWoosim = Character 
     .toString((char) 0xd9); // La 

// (Sticky!!!)

    public struc(char Character, char EndGlyph, char IniGlyph, 
      char MidGlyph, char IsoGlyph) { 
     character = Character; 
     endGlyph = EndGlyph; 
     iniGlyph = IniGlyph; 
     midGlyph = MidGlyph; 
     isoGlyph = IsoGlyph; 
    }
