在android Textview中，阿拉伯语文本没有正确显示它将单词分成字母。是否有任何库或其他方法来解决此问题？
答案 0 :(得分：1)
你可以使用Farsi Class来做到这一点。
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)

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

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