android - 如何在 Android 中支持阿拉伯语文本?

我已成功从服务器获取阿拉伯语文本。检索到的文本我想在代码中显示,但它的显示框而不是阿拉伯文本。假设 t 数组值是来自服务器的阿拉伯文本。

string[] t={" "};
Textview tv = (Textview) findviewByid(R.id.text);
tv.setText(t[0]);

最佳答案

Android 2.1 没有阿拉伯字体。

Android 2.2 有阿拉伯字体,但不能正确显示您的单词。

Android 3.x 完全支持阿拉伯语。

对于 Android 2.1,您必须设置字体 Farsi.GetFarsiFont(this) 然后使用 Farsi.Convert("سلام")

对于 Android 2.2,您不需要设置字体,但必须使用 Farsi.Convert("سلام")

对于 Android 3.x,忘记上述所有解决方案;)。但如果您不喜欢 3.x 阿拉伯字体,您可以更改字体。

请执行以下步骤:

1) 首先在 assets 文件夹中添加“TAHOMA.TTF”

2) 使用以下类获取字体并将您的阿拉伯语或波斯语文本转换为在您的 Activity 中显示的良好形式。

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!!!)
