Как показать арабский текст в TextView на Android?

Question

В андроиде Textview арабский текст не отображается правильно, он разбивает слово на алфавит. Есть ли библиотека или другой способ решить эту проблему?

Answer 1

вы можете использовать Farsi Class для этого.

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!!!) 

    private static final class struc { 
     public char character; 
     public char endGlyph; 
     public char iniGlyph; 
     public char midGlyph; 
     public char isoGlyph; 

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

и для вызова, что:

Typeface tf = Farsi.GetFarsiFont(this); 
MyTextView.setTypeface(tf); 
MyTextView.setText(Farsi.Convert("سلام")); 

вам нужно TAHOMA.TTF»в папке активов слишком

для получения дополнительной информации см это link

, если вы не хотите добавить шрифт для вашего приложения просто используйте

MyTextView.setText(Farsi.Convert("سلام"));
