该按钮在ScrollView内的表格下方是静态的,但如果表格过长,则该按钮位于可见区域之外
我需要动态地创建一个按钮,在桌子下面(和桌子里面?)
我用下面的代码(和其他代码)进行了尝试:
日志:
java.lang.RuntimeException: Unable to start activity ComponentInfo{eu.straff/eu.straff.OutAcceptActivity}: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
第二种方法中的“标签”是什么?看起来它属于另一个父视图,因此不能对其调用
addView(label)
。此外,您正在创建一个新按钮,但您没有在任何地方调用addView(myButton)
。噢,谢谢,必须有myButton而不是label。谢谢,但是onClick方法不起作用,我是怎么做到的?帮帮我!
