如何在Android中支持阿拉伯语文本?

我成功从服务器获取阿拉伯语文本。检索到的文本我希望在代码中显示,但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语文本。

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

Android 2.1没有阿拉伯字体。

Android 2.2具有阿拉伯字体,但未正确显示您的字词。

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,忘记了上述所有解决方案;)。但如果你不喜欢3.x阿拉伯字体,你可以改变字体。

以下步骤也是如此:

1)首先在资产文件夹

中添加“TAHOMA.TTF”

2)使用以下类来获取字体并将您的阿拉伯语或波斯语文本转换为一个好的表单,以便在您的活动中显示。

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

    public static boolean isFarsiConversionNeeded = true;

            .toString((char) 0xfedf)
            + Character.toString((char) 0xfe8e); // Lam + Alef

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

我对波斯语课的参考: Arabizer

答案 1 :(得分:8)

我想在用阿拉伯语挣扎数周之后添加我的经验。事实上,当我在我的Android应用程序中使用阿拉伯字体时,这篇文章非常有用。

我使用了波斯语类来重新翻译文本。但这不符合我的期望。因为,客户总是过多考虑应用程序的每个字母,而且是安排。

在波斯语类中,一个问题是它不能正确地重新排列右括号。就像那样,我注意到了几个问题。

然而,当我使用ArabicUtility类时,我注意到它比Farsi类更好地改进了文本呈现。 https://github.com/agawish/Better-Arabic-Reshaper/commits/master

请注意,您必须在assests文件夹中安装字体,并且可以从此类更改字体类型。另外,我在上面的类中添加了一个新方法来获取文本 从字符串文件和设置文本到textviews。

这是代码。

public void addTranslate(int rid, TextView txt1, Context context) {
        String textv = context.getResources().getString(rid);
        txt1.setText(ArabicUtilities.reshapeSentence(textv));


    }

在您的活动中使用上述方法,您只需要传递上述三个参数。

答案 2 :(得分:3)

尝试将任何阿拉伯字体复制到资源文件夹中并设置该字体并检查它是否可行

string[] t={"arabic words here"};
TextView tv=(TextView)findViewById(R.id.text); 
Typeface face=Typeface.createFromAsset(getAssets(), "fonts/HandmadeTypewriter.ttf");
tv.setTypeface(face)

使用HandmadeTypewriter.ttf字体的阿拉伯字体 或

尝试设置静态阿拉伯语文本并检查其是否正常工作?

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

答案 3 :(得分:-1)

tv.setTypeFace并为阿拉伯语设置正确的ttf
