当我在显示时单击外部virtualKeyboard
时,我收到一条Dialog
显示此消息:
An internal application error occured :
java.lang.IllegalArgumentException : Component is already contained in Container :
Container[x=0 y=140 width=240 height=180, layout = BorderLayout, scrollableX = false, scrollableY = true, components = [VirtualKeyboard$1, Container]]
在多次显示virtualKeyboard
.
我查看了我的代码,但没有找到任何单词BorderLayout
!
那么如何纠正这个错误呢?
