Java 无法识别阿拉伯语字符

我正在使用java和php从android studio中的数据库检索文本。英文文本显示成功，但当我将阿拉伯语添加到数据库时，它在Android中显示为方框。你们能帮我解决这个问题吗

它可以在html浏览器页面中完美地工作。但在安卓系统中，情况并非如此。但是，它的xml文件设置为UTF8。它应该是有效的。有人能找出问题吗

    resultView = (TextView) findViewById(R.id.textView);

    getData();
//button

    Button insert=(Button) findViewById(R.id.button);

    insert.setOnClickListener(new View.OnClickListener() {

        @Override

它有完整的指南如何在Android中显示阿拉伯语

此外，您还需要在Android项目中包含一些类。 跟着指南走，你就会知道你要做什么

一个简单的例子

AssetManager manager=this.getAssets();
manager.open("tahoma.ttf");
TextView tv=(TextView)this.findViewById(R.id.textView);
tv.setTypeface(Typeface.createFromAsset(manager, "tahoma.ttf"));
tv.setTextSize(50f);
tv.setText(ArabicUtilities.reshape(" الحمد لله hello"));

---

String appname=String.valueOf（Html.fromHtml（“您的阿拉伯文文本））；

我的Android Studio是什么意思？你是说IDE预览还是在你的设备上实际运行应用程序？我正在我的设备上运行应用程序。它的操作系统版本是lolipop 5.0。可能是编码错误，你是否尝试从string.xml文件中显示阿拉伯文文本？不！你能指导我如何使用吗在string.xml文件中执行此操作您能试试这个吗，

yourTextView.setText（Html.fromHtml（“您的字符”）；

AssetManager manager=this.getAssets();
manager.open("tahoma.ttf");
TextView tv=(TextView)this.findViewById(R.id.textView);
tv.setTypeface(Typeface.createFromAsset(manager, "tahoma.ttf"));
tv.setTextSize(50f);
tv.setText(ArabicUtilities.reshape(" الحمد لله hello"));
