我正在开发一个简单的应用程序,它有两个活动,mainactivity和secondactivity,还有一个扩展对话框的透明customactivity。main活动有两个按钮( Yes_button
以及 No_button
).
当用户单击时 Yes_button
,第二个活动通过intent调用,customactivity将位于它前面。
当用户单击时 No_button
第二个活动也将被调用,但customactivity不会与之一起被调用。
customactivity的调用基于if else语句表达式。customactivity有一个skip按钮,单击时customactivity将关闭,只有这样用户才能访问secondactivity。secondactivity只有一个按钮调用mainactivity,循环继续。
问题
当应用程序启动,用户点击 No_button
,将调用secondactivity而不调用customactivity(如预期!),但是一旦用户点击 Yes_button
,即使 No_button
已单击。
期望
我希望每次 Yes_button
单击,并且在 No_button
是单击。

在android中,要将数据从一个活动传递到另一个活动,不需要声明静态变量(
getNumber
在mainactivity中,应该使用intent和bundle。请参阅下面的解决方案。主活动.java
secondactivity.java文件
