尝试将多个项目添加到滚动条中,我很快发现所有“addActor”功能都不支持.所以,我添加了一个表,我想要的所有项目(这个代码错过了我仍然想添加的图像)来创建一个可滚动的信用屏幕…但这种方法(当前)不允许溢出,渲染ScrollPane没用. (我的文字只显示到屏幕高度允许的位置,不可滚动).
在LibGDX中创建带有多个小部件的可滚动窗格的方法是什么？ (我目前只关心 Android和Win / Lin / Mac平台.

pane = new ScrollPane(null,skin);
pane.setFillParent(true);
paneContent = new Table(skin);
paneContent.setFillParent(true);
Label temp = new Label("",skin);
temp.setAlignment(Align.left,Align.center);
temp.setText( Gdx.files.internal("licenses/credits.txt").readString("UTF-8") );
paneContent.addActor(temp);
pane.setWidget(paneContent);
stage.addActor(pane);
解决方法
如果要将多个项目放入ScrollPane,您只需要在其中放置一个表,并为要放入ScrollPane的每个小部件调用add().
以下是如何使您的信用可滚动的示例：
public class ScrollTest implements ApplicationListener {
private Stage stage;
private static final String reallyLongString = "This\nIs\nA\nReally\nLong\nString\nThat\nHas\nLots\nOf\nLines\nAnd\nRepeats.\n"
+ "This\nIs\nA\nReally\nLong\nString\nThat\nHas\nLots\nOf\nLines\nAnd\nRepeats.\n"
+ "This\nIs\nA\nReally\nLong\nString\nThat\nHas\nLots\nOf\nLines\nAnd\nRepeats.\n";
@Override public void create() {
this.stage = new Stage();
Gdx.input.setInputProcessor(this.stage);
final Skin skin = new Skin(Gdx.files.internal("skin/uiskin.json"));
final Label text = new Label(reallyLongString,skin);
text.setAlignment(Align.center);
text.setWrap(true);
final Label text2 = new Label("This is a short string!",skin);
text2.setAlignment(Align.center);
text2.setWrap(true);
final Label text3 = new Label(reallyLongString,skin);
text3.setAlignment(Align.center);
text3.setWrap(true);
final Table scrollTable = new Table();
scrollTable.add(text);
scrollTable.row();
scrollTable.add(text2);
scrollTable.row();
scrollTable.add(text3);
final ScrollPane scroller = new ScrollPane(scrollTable);
final Table table = new Table();
table.setFillParent(true);
table.add(scroller).fill().expand();
this.stage.addActor(table);
}
@Override public void render() {
this.stage.act();
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
this.stage.draw();
}
@Override public void resize(final int width,final int height) {}
@Override public void pause() {}
@Override public void resume() {}
@Override public void dispose() {}
}
