第二阶段的输入侦听器在 libgdx 中不起作用答案

【问题标题】：input listener in second stage not working in libgdx第二阶段的输入侦听器在 libgdx 中不起作用

【问题描述】：

我想在同一个屏幕上有两个阶段，但问题是，第二阶段（static_stage）的输入侦听器没有响应，但在绘制其演员时没有问题。第一阶段（阶段）工作并且响应良好.这是代码，请告诉我哪里出错了？

    Tile_manager.load();

    camera.update();

    game.batch.begin();
    game.batch.draw(sprite_back, 0, 0);
    game.batch.end();

    shuffle=new Label("SHUFFLE", shuffle_style);
    shuffle.setPosition(190, 1330);

    shuffle.addListener(new InputListener(){

    static_stage.addActor(shuffle);

【解决方案1】：

我也面临同样的问题。但首先，你把输入监听器弄得一团糟，你必须设置一个输入多路复用器来管理两个输入

InputMultiplexer inputMultiplexer = new InputMultiplexer();
inputMultiplexer.addProcessor(stage);
inputMultiplexer.addProcessor(static_stage);
Gdx.input.setInputProcessor(inputMultiplexer);

但不确定这是否足够......
