私は新しい Android 開発者です。アプリでラテン フォントを使用していますが、それを機能させることができず、文字の取得を続けることができません?。私のコードは以下のとおりです。SQLite データベースを使用しています。中身。

これを正しく表示するにはどうすればよいですか？

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);
}

私のエミュレータ画面：

ここに画像の説明を入力

私もこのコードを試しました：

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);
}

しかし、これは私に次のエラーを与えています:

Typeface 型のメソッド createFromAsset(AssetManager, String) は、引数 (String, String) には適用されません。

そして、私は Sqlitehelper クラスを使用しました 私のコードは以下の通りです:

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,
                SQLiteDatabase.OPEN_READONLY);

あなたがコードで何をしたのか、なぜHTMLを使用したのかわかりません。しかし、私はあなたがこの単純なコードを必要としていると仮定することができます。以下の修正された方法を参照してください。

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);
}

「？」の代わりの文字だと思います 「ボン？」は「ō」U+014D LATIN SMALL LETTER O WITH MACRONです。これが、実際に唯一の賢明な可能性だからです。ラテン語自体はプレーンなAからZの文字のみを使用して書かれていますが、マクロンは、母音が長く発音されることを示すために、辞書や文法で母音の上に使用されることがよくあります。

文字「ō」は実際のAndroidデバイスではOKと表示されますが、エミュレータにフォントの問題がある可能性があります（つまり、使用しているフォントに文字が含まれていません）。おそらく、文字エンコードの問題があります。それ以上の情報（たとえば、どのエミュレーターが使用されているか、文字がHTMLでどのように表現されているか、HTMLドキュメントのエンコードがどのように宣言されているか、実際のエンコードは何か）がないと分析できません。
