Question

这一个正在摧毁我的大脑，当你进入活动时，你可以点击paypal按钮，你就可以进入贝宝活动了。如果您取消PayPal活动，您将被带回原始活动。从这里再次单击按钮没有任何反应。我尝试在OnClick方法中将基本消息打印到控制台，它甚至没有显示，它似乎没有注册点击。我假设问题与布局xml文件或清单文件无关。我会发布一张图片，但我不能因为我是新的，所有你需要知道的是它的结账屏幕真的有支付宝按钮。

Answer 1

在onClick（）

之后尝试使用launchPayPalButton.updateButton（）

Answer 2

如果您仍在寻找答案，我有一个

如果您查看getCheckoutButton方法，则需要Context作为参数，因此当Activity用于说当你开始另一个Activity时会发生暂停，CheckoutButton的实例会以某种方式丢失。

我修复了在Activity的onResume中使用updateButton方法

@Override
protected void onResume() {
    /**
     * The CheckoutButton has to be updated each time the Activity is
     * resumed, otherwise the onClickListener of CheckoutButton will not work
     **/
    if (mCheckOutBtn != null && (mCheckOutBtn instanceof CheckoutButton))
        mCheckOutBtn.updateButton();
    super.onResume();
}

考虑到您在PayPal的{{1}}中初始化了CheckoutButton库和onCreate，这是有效的。

Android Paypal启动按钮OnClick仅在活动生命周期中执行一次
