Libgdx为什么我的按钮在鼠标点击时没有响应

Question

为什么我的TextButtonlibgdx没有响应点击？

我有一个按钮,这个按钮有一个监听器,但它没有响应.该按钮正在显示,但它不会响应鼠标点击.

public MyStage extends Stage {
     ...
     next.addListener(new InputListener() {
        @Override
        public boolean touchDown(InputEvent event, float x, float y, int pointer, int button)
        {
            Gdx.app.log(ApothecaryGame.LOG, "Pressed: Next button.");
            return true;
        }
        @Override
        public void touchUp(InputEvent event, float x, float y, int pointer, int button) {
            Gdx.app.log( ApothecaryGame.LOG, "Released: Next button.");
            super.touchUp( event, x, y, pointer, button );
            nextPage();
        }
    } );
    this.addActor(next);
}

将ClickListener添加到按钮.它看起来像这样.

button.addListener(new ClickListener() {
    public void clicked(InputEvent event, float x, float y) {
        // Do something interesting here...
    }
});

此外,请确保将舞台设置为输入处理器,否则将无法看到事件.

Gdx.input.setInputProcessor(stage);
