我在表单上添加了一个名为 的btnBar容器boxlayout(x-axis)。容器有 4 个自定义类的按钮，MyButton它们从Button自身扩展。当我添加actionlistener到容器中的一个按钮时，每个按钮都会调用它。即使该actionevent.getsource.gettext方法返回相同的值，而与焦点无关。我已经通过数组添加了按钮，我尝试使用的是这样的：
btns[0].addActionListener(......)
我哪里错了？

You must never use setFocus, you should use setFocusable to toggle focusability and requestFocus to get the focus to a specific component.
You should also migrate to Codename One, since LWUIT is pretty much unmaintained.
