推荐答案

转到xml文件

转到您的工具，右键单击=>属性=>可见性并标记不可见
或
您可以编写android:visibility ="invisible"

并为事件设置可见性setVisiblity(true)...

逻辑就是你了...

Go to xml file

Go to your tool right click => property => visibility and tick on invisible
OR
you can write android:visibility="invisible"

and for visibility setVisiblity(true) on event...

and logic is yours...

如果你是android开发人员，请检查
btnprevious.setVisibility(true);
喜欢它是否起作用.
谢谢

are you android developer if yes then check
btnprevious.setVisibility(true);
like that its working or not.
Thanks
