将绝对定位结合到Java项目中
现在我正在研究一个石头剪刀项目。
这很简单，但我是java的新手，并且正在努力解决游戏的一些方面问题。
我的基本游戏都运行良好，但是我试图添加一个在顶部或底部角落显示的评分系统，每次你赢得你的分数上升，和计算机相同，我还没有真正决定在哪里放他们。
我正在使用JLabel来获取数字，我一直在尝试一些方法，但有些失败的方法仍在那里。
我一直在使用integer to String作为标签。我在遇到有人评分时更新号码以及定位JLabel时遇到问题。
到目前为止，与分数相关的大部分内容都在代码底部附近的得分方法中，大多数评分事项的变量都是yourNum，yourScore，compScore ，compNum。
对于定位问题，我希望使用绝对定位但我不完全理解如何在我的JLabel中使用它，所以如果有人能解释如何在我的情况下使用它会很棒。这是我的完整代码。

2 个答案:
答案 0 :(得分：0)
首先，我讨厌绝对定位。
如果要使用绝对定位，则必须将父容器的布局设置为null（可以是JFrame或任何您想要的）。
然后你可以添加一个新的JLabel，用setLocation（）方法定位它。
顺便说一下，我认为您的代码存在一些问题，可能会复制粘贴问题。如果你想发布一些内容并让别人阅读它，试着发布一个SSCCE
但我总是建议使用像BoxLayout这样的东西。请看一下我对图形有趣的答案：
Positioning of components (how to place a few buttons center screen same size)
Jframe not the right size when its executed, any reason why?
答案 1 :(得分：0)
我会以激情避免绝对布局。
您不仅需要监视每个组件的更改以查看它可能会更改大小，还需要考虑这些更改如何影响其他组件并监视父容器的更改...并且不要甚至让我开始研究平台，字体，屏幕分辨率之间的差异......
为什么浪费你的时间Swing已经为你做了所有这些......
我会使用复合布局来包含感兴趣的各个区域。
例如，我将所有播放器控件放入一个面板中，我将任何计算机输出放入其自己的面板中，然后将得分放入自己的面板中。
这将责任分离到每个容器，允许您为每个部分使用不同的布局，而无需花时间尝试让它们通过单个布局对齐。
现在这只是我的看法，你可以做很多其他的事情，并从许多不同的方式解决问题......
