我是一名新的 Android 开发人员。我在我的应用程序中使用拉丁字体，但我无法让它工作并继续获得一个?字符。我的代码在下面，使用 sqlite 数据库。我必须从 Sqlite 数据库中获取文本，并且每个特殊的拉丁字符（即 à、ò、ù、è...）都显示为带有“？”的黑色方块 里面。

我怎样才能正确显示这个？

private void displayTestQuestion() {
    resetEverything();
    stats.setText(Integer.toString(totalRightQuestions)+"/"+Integer.toString(totalNumberOfQuestions));

    String questionText = questionCursor.getString(0);
    question.setText(Html.fromHtml(questionText));
    adjectiveNumber = questionCursor.getString(1);
    adjectiveCase = questionCursor.getString(3);
    adjectiveGender = questionCursor.getString(2);
}

我的模拟器屏幕：

在此处输入图像描述

我也试过这段代码：

private void displayTestQuestion() {
    resetEverything();
    stats.setText(Integer.toString(totalRightQuestions)+"/"+Integer.toString(totalNumberOfQuestions));

    String questionText = questionCursor.getString(0);
    Typeface font = Typeface.createFromAsset(questionCursor.getString(0), "fonts/LATINWD.TTF");
    //question.setText(Html.fromHtml(questionText));
    question.setText((CharSequence) font);
    adjectiveNumber = questionCursor.getString(1);
    adjectiveCase = questionCursor.getString(3);
    adjectiveGender = questionCursor.getString(2);
}

但这给了我以下错误：

Typeface 类型中的 createFromAsset(AssetManager, String) 方法不适用于参数 (String, String)。

我使用了 Sqlitehelper 类，我的代码如下：

public class VocabTesterDatabaseHelper extends SQLiteOpenHelper {

    private static String DB_PATH = "data/data/com.VoacabTester/databases/";

    private static String DB_NAME = "vocabdb.db";

    private SQLiteDatabase vocabDatabase;

    private final Context vocabContext;

    public VocabTesterDatabaseHelper(Context context) {
        super(context, DB_NAME, null, 3);
        this.vocabContext = context;
    }

    public void createDataBase() throws IOException {

        boolean dbExist = checkDataBase();

        if (dbExist) {

        } else {
            this.getReadableDatabase();
            copyDataBase();
        }

    }

    private boolean checkDataBase() {

        File dbFile = new File(DB_PATH + DB_NAME);
        return dbFile.exists();
    }

    private void copyDataBase() throws IOException {
        try {

            InputStream myInput = vocabContext.getAssets().open(DB_NAME);
            String outFileName = DB_PATH + DB_NAME;

            // Open the empty db as the output stream
            OutputStream myOutput = new FileOutputStream(outFileName);

            byte[] buffer = new byte[1024];
            int length;
            while ((length = myInput.read(buffer)) > 0) {
                myOutput.write(buffer, 0, length);
            }
            myOutput.flush();
            myOutput.close();
            myInput.close();
        } catch (IOException e) {
            Log.v("data", e.toString().concat("sql"));
        }
    }

    public void openDataBase() throws SQLException {

        // Open the database
        String myPath = DB_PATH + DB_NAME;
        vocabDatabase = SQLiteDatabase.openDatabase(myPath, null,

我的猜测是代替“？”的字符 在“邦？” 是带有 MACRON 的“ō” U+014D 拉丁文小写字母 O，因为这确实是唯一合理的可能性。拉丁语本身仅使用简单的 A 到 Z 字母书写，但在字典和语法中，长音符号通常用于元音上方，以表示元音发音很长。

字符“ō”在实际的 Android 设备上显示 OK，但您的模拟器可能存在字体问题（即，它使用的字体不包含该字符）。更有可能的是，存在字符编码问题。如果没有进一步的信息（例如，使用哪个模拟器，字符在 HTML 中如何表示，HTML 文档的编码是如何声明的，以及实际编码是什么），几乎无法对其进行分析。

我不知道您在代码中做了什么以及为什么使用 HTML ？但我可以假设你需要这个简单的代码。请参阅下面的修改方法。

private void displayTestQuestion() {
    resetEverything();
    stats.setText(Integer.toString(totalRightQuestions)+"/"+Integer.toString(totalNumberOfQuestions));

    String questionText = questionCursor.getString(0);
    Typeface font = Typeface.createFromAsset(getContext().getAssets(), "fonts/LATINWD.TTF");
    question.setTypeface(font);
    question.setText(questionText);
    adjectiveNumber = questionCursor.getString(1);
    adjectiveCase = questionCursor.getString(3);
    adjectiveGender = questionCursor.getString(2);
}
