如果您想将多个项目放入 ScrollPane,您只需将表格放入其中并为您要放入 ScrollPane 的每个小部件调用 add()。
以下是如何使您的学分可滚动的示例:
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() {}
}
编辑:添加了在 ScrollPane 内设置表格的代码。
