这个正在毁掉我的大脑,当你进入 Activity 时,你可以点击 paypal 按钮,然后你就可以进入 paypal Activity 了。如果您取消 Paypal Activity ,您将回到原来的 Activity 。从这里,如果您再次单击该按钮,则不会发生任何事情。我尝试在 OnClick 方法中打印一条基本消息到控制台,但它甚至没有显示,它似乎没有记录点击。我假设问题与布局 xml 文件或 list 文件无关。我会张贴图片,但我不能,因为我是新手,您只需要知道它是一个带有 paypal 按钮的结帐屏幕。
提前致谢, 休。

最佳答案
在 onClick() 之后尝试 launchPayPalButton.updateButton()
关于Android Paypal 启动按钮 OnClick 在 Activity 生命周期内只执行一次,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/9691578/
