java - Codenameone FloatingHint 问题

Question

尝试使用 Codename One FloatingHint 类，但在运行应用程序时我得到一个 java.lang.IllegalArgumentException: Component is already contained in Container。这是我的实现

Form f = new Form(new BoxLayout(BoxLayout.Y_AXIS));
TextField hintTest= new TextField(11);
hintTest.setHint("The hint");
new FloatingHint(hintTest);
addComponent(hintTest);

Answer 1

设法让它与

一起工作

    TextField hintTest= new TextField(11);
    hintTest.setHint("The Hint");
    FloatingHint x = new FloatingHint(uname);
    addComponent(x);
