I am a new Android developer. I’m working with a Latin font in my app but I can’t get it to work and keep getting a ? for the character. My code is below, using an sqlite database.I have to fetch text from an Sqlite database and every special Latin character (i.e. à, ò, ù, è…) was displayed with black squares with a “?” inside.
How can i display this correctly?
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);
}
My emulator screen:
I’ve also tried this code:
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);
}
But this is giving me the following error:
The method createFromAsset(AssetManager, String) in the type Typeface is not applicable for the arguments (String, String).
And i used Sqlitehelper class my code is below:
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;
}

return dbFile.exists();
}

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"));
}
}

vocabDatabase = SQLiteDatabase.openDatabase(myPath, null,

I don’t know what you have done in code and why used HTML ? but I can assume you need this simple code. please see below modified method.
