如何在 Android 中支持阿拉伯语文本? [英] How to support Arabic text in Android?
本文介绍了如何在 Android 中支持阿拉伯语文本?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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，但它显示的是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.
I am getting Arabic text from server successfully. Retrieved text I want display in code but its showing boxes instead of Arabic text. Assume that t array values are Arabic text from server.
string[] t={" "};
Textview tv = (Textview) findviewByid(R.id.text);
tv.setText(t[0]);
推荐答案
Android 2.1 没有阿拉伯字体.
Android 2.1 does not have Arabic font.
Android 2.2 具有阿拉伯字体，但无法正确显示您的字词.
Android 2.2 has Arabic font but does not show your word correctly.
Android 3.x 完全支持阿拉伯语.
Android 3.x supports Arabic completely.
对于 Android 2.1，您必须设置字体 Farsi.GetFarsiFont(this) 然后使用 Farsi.Convert("سلام")
For Android 2.1 you must set the typeface Farsi.GetFarsiFont(this) and then use Farsi.Convert("سلام")
对于 Android 2.2 你不需要设置字体但必须使用 Farsi.Convert("سلام")
For Android 2.2 you do not need setting font but must use Farsi.Convert("سلام")
对于 Android 3.x，忘记上述所有解决方案；).但是如果您不喜欢 3.x 阿拉伯字体，可以更改字体.
And for Android 3.x forget all of the above solutions ;). But you can change the font if you do not like the 3.x Arabic font.
请执行以下步骤:
1) 首先在assets文件夹中添加TAHOMA.TTF"
1) At first add "TAHOMA.TTF" in assets folder
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活动中显示的良好形式.
2) use the following class to get the font and converting your Arabic or Farsi text to a good form for showing in your activities.
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

private final static String szLamAndAlefWoosim = Character

private final static String szLamStickAndAlefWoosim = Character
