我試圖實現一個不同的字體比使用TextFieldStyle默認的字體，因爲我已經被告知。它在一個文本框裏面，我想改變字體。但還沒有設法做到這一點。在Libgdx的TextFieldStyle
這是類本身：
public class StoneScreen implements Screen {
OrthographicCamera camera;
final TombStone game;
//Textures and art.
public Texture background, sdStone, arrowBack;
public Sprite backgrounds;
//TextField´s stuff
private Stage stage;
private Skin skin;
ImageButton btnArrow;
public StoneScreen(TombStone gam) {
this.game = gam;
camera = new OrthographicCamera();
camera.setToOrtho(false, 136, 204);
game.assets.load();
loadStandard();
}
public void loadStandard(){
background = game.assets.background;
sdStone = game.assets.sdStone;
//backgrounds = Assets.backgrounds;
}
@Override
public void render(float delta) {
Gdx.gl.glClearColor(0, 0, 0.2f,1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
//Recieves the screen width and height
float gameHeight = Gdx.graphics.getHeight();
float gameWidth = Gdx.graphics.getWidth();
camera.update();
game.batch.setProjectionMatrix(camera.combined);
game.batch.begin();
Gdx.app.log("X", "FPS:" + Gdx.graphics.getFramesPerSecond());
game.batch.draw(background,0,0, 136, 204);
game.batch.draw(sdStone, 40, 20, 70, 110);
//SpriteBatch batcher = (SpriteBatch)stage.getBatch();
game.batch.end();
stage.act(Gdx.graphics.getDeltaTime());
stage.draw();
}
@Override
public void resize(int width, int height) {
// TODO Auto-generated method stub
}
@Override
public void show() {
BitmapFont textFont;
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("NothingYouCouldDoBold.ttf"));
FreeTypeFontParameter parameter = new FreeTypeFontParameter();
parameter.size = 12;
textFont = generator.generateFont(parameter);
//String text = Gdx.app.getPreferences("prefs").getString("text", "Default text if missing");
//String txtArea = Gdx.app.getPreferences("prefs").getString("text", "Default text if missing");
Preferences prefs = Gdx.app.getPreferences("preferences");
Skin skin = new Skin();
Skin textSkin = new Skin();
skin.add("font", textFont);
stage = new Stage();
Gdx.input.setInputProcessor(stage);
skin = new Skin(Gdx.files.internal("uiskin.json"));
TextFieldStyle textstyle = new TextFieldStyle();
textstyle.font = textSkin.getFont("textFont");
final TextArea textArea = new TextArea(prefs.getString("textArea", "Enter text:"), skin);
textArea.setX(500);
textArea.setY(500);
textArea.setWidth(270);
textArea.setHeight(270);
textArea.setMaxLength(50);
final TextField textField = new TextField(prefs.getString("textField", "Enter name:"), textstyle);
textField.setX(500);
textField.setY(750);
textField.setMaxLength(20);
//textField.setWidth(450);
//textField.setHeight(200);
textField.setSize(400, 200);
//String text = Gdx.app.getPreferences("prefs").getString("text", "Default text if missimg");
//TextField textField = new TextField(text, skin);
//Backbutton
ImageButtonStyle styleTwo = new ImageButtonStyle();
TextureRegionDrawable arrowImage = new TextureRegionDrawable(new TextureRegion(new Texture("arrowLeft.png")));
styleTwo.up = skin.newDrawable(skin.newDrawable(arrowImage));
styleTwo.down = skin.newDrawable(skin.newDrawable(arrowImage));
btnArrow = new ImageButton(styleTwo);
btnArrow.setSize(150, 150);
btnArrow.setPosition(450, 10);
stage.addActor(textArea);
stage.addActor(textField);
stage.addActor(btnArrow);
//Backbutton takes us back to mainmenu
btnArrow.addListener(new ChangeListener() {
@Override
public void changed(ChangeEvent event, Actor actor) {
game.setScreen(new MainScreen(game));
//Saves the entered text.
Preferences prefs = Gdx.app.getPreferences("preferences");
prefs.putString("textField", textField.getText());
prefs.putString("textArea", textArea.getText());
prefs.flush();
}
});
}
@Override
public void hide() {
// TODO Auto-generated method stub
}
@Override
public void pause() {
// TODO Auto-generated method stub
}
@Override
public void resume() {
// TODO Auto-generated method stub
}
@Override
public void dispose() {
// TODO Auto-generated method stub
}
}
而且這段代碼的重要組成部分，顯示（）類中。我在哪裏沒有成功。我得到錯誤說：

所以..我可能在這裏做錯了什麼？
