因此在场景AI中只有几个按钮，其中一个导致场景B.当我打开场景B时，表格元素放置不正确，前一个场景中的按钮不可见，但如果我点击前一个按钮的位置场景它打开一个在场景A上打开的场景。
我希望这对你有用。
我认为问题出在处理方法中。
这是我的场景B的代码：
public class Postavke implements Screen {
Main main = null;
// KONSTRUKTOR ZA MJENJANJE SCENE
public Postavke(Main gm){
main = gm;
}
Stage postavkeStage = null;
private Image pozadina = null;
@Override
public void show() {
postavkeStage = new Stage(new StretchViewport(1920, 1080));
pozadina = new Image(new Texture(Gdx.files.internal("pozadinaPostavke.png")));
postavkeStage.addActor(pozadina);
postavkeButtoni();
}
@Override
public void render(float delta) {
Gdx.gl.glClearColor(0, 0, 0, 0);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
postavkeStage.draw();
postavkeStage.act();
}
@Override
public void resize(int width, int height) {
}
@Override
public void pause() {
}
@Override
public void resume() {
}
@Override
public void hide() {
}
@Override
public void dispose() {
postavkeStage.dispose();
}
private void postavkeButtoni(){
Table postavkeButtoni = new Table();
postavkeButtoni.setFillParent(true);
final Image zvukButton = new Image(new Texture(Gdx.files.internal("postavkemutebutton.png")));
final Image homeButton = new Image(new Texture(Gdx.files.internal("homebutton.png")));
final Image mailButton = new Image(new Texture(Gdx.files.internal("postavkegmailbutton.png")));
final Image instagramButton = new Image(new Texture(Gdx.files.internal("postavkeinstagrambutton.png")));
final Image zaslugeButton = new Image(new Texture(Gdx.files.internal("postavkezaslugebutton.png")));
zvukButton.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){
zvukButton.addAction(Actions.scaleTo(1, 1.1f,.1f));
return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button){
zvukButton.addAction(Actions.scaleTo(1, 1,.1f));
main.setScreen(new MainMenu(main));
}
});
homeButton.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){
homeButton.addAction(Actions.scaleTo(1, 1.1f,.1f));
return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button){
homeButton.addAction(Actions.scaleTo(1, 1,.1f));
}
});
mailButton.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){
mailButton.addAction(Actions.scaleTo(1, 1.1f,.1f));
return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button){
mailButton.addAction(Actions.scaleTo(1, 1,.1f));
}
});
instagramButton.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){
instagramButton.addAction(Actions.scaleTo(1, 1.1f,.1f));
return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button){
instagramButton.addAction(Actions.scaleTo(1, 1,.1f));
}
});
zaslugeButton.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){
zaslugeButton.addAction(Actions.scaleTo(1, 1.1f,.1f));
return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button){
zaslugeButton.addAction(Actions.scaleTo(1, 1,.1f));
}
});
postavkeButtoni.add(homeButton).expand().top().left().pad(20);
// postavkeButtoni.row();
postavkeButtoni.add(zvukButton);
//postavkeButtoni.row();
HorizontalGroup drustveneMrezeIZasluge = new HorizontalGroup();
postavkeButtoni.addActor(mailButton);
postavkeButtoni.addActor(instagramButton);
postavkeButtoni.addActor(zaslugeButton);
postavkeStage.addActor(postavkeButtoni);
}
}
为什么没有正确放置东西并摧毁场景A？

public class MainMenu implements Screen {

答案 0 :(得分：1)
您可以看到简单的代码：
1-创建MainGame扩展Game：
public class Main extends Game {
@Override
public void create() {
setScreen(new SceneA());
}
@Override
public void dispose() {
// your SceneA and SceneB here will dispose here after you call setScreen(new ____());
getScreen().dispose();
System.out.println("\n" + getScreen().getClass().getSimpleName() + " disopsed");
System.out.println("=========================================================");
}
}
2- Craete SceneA实施Screen：
public class SceneA implements Screen {
private Stage stage;
@Override
public void show() {
System.out.println("\nshow SceneA");
stage = new Stage(new StretchViewport(1920, 1080));
Image button = new Image(new Texture("____.png"));
button.addListener(new ClickListener() {
public void clicked(InputEvent event, float x, float y) {
((Game) Gdx.app.getApplicationListener()).dispose();
((Game) Gdx.app.getApplicationListener()).setScreen(new SceneB());
}
});
stage.addActor(button);
// don't forget to call this to be able to handle stage inputs
Gdx.input.setInputProcessor(stage);
}
// ........ here remaining methods (resize(), resume(), pause(), hide())
@Override
public void dispose() {
stage.dispose();
System.out.println("\ndispose SceneA");
}
}
3-创建SceneB实施Screen：
public class SceneB implements Screen {
private Stage stage;
@Override
public void show() {
System.out.println("\nshow SceneB");
stage = new Stage(new StretchViewport(1920, 1080));
Image button = new Image(new Texture("____.png"));
button.addListener(new ClickListener() {
public void clicked(InputEvent event, float x, float y) {
((Game) Gdx.app.getApplicationListener()).dispose();
((Game) Gdx.app.getApplicationListener()).setScreen(new SceneA());
}
});
stage.addActor(button);
// don't forget to call this to be able to handle stage inputs
Gdx.input.setInputProcessor(stage);
}
// ........ here remaining methods (resize(), resume(), pause(), hide())
@Override
public void dispose() {
stage.dispose();
System.out.println("\ndispose SceneB");
}
}
