在应用程序购买保存按钮状态

标签： android in-app-purchase in-app-billing

我正在尝试使用应用程序内购买开发应用程序，我想做的就是让两个按钮一个用于购买（启用）第二个按钮以在购买后打开活动（首先禁用然后在购买后启用）。 第一个问题是第一个是在购买后保存按钮状态，因为每次重新启动应用程序时它们都会重置。所以我做了一些研究，发现了共享偏好，我确实实现了它，但第二个问题是在实现共享偏好后，按钮状态似乎不正常（在禁用和启用之间）。

请注意，在应用程序中，我有两个按钮，它们执行相同的操作，但是没有进行购买，并且它们在共享首选项下工作正常，但与应用内购买相关联的按钮停止从禁用状态更改其状态购买后启用（购买后保持禁用状态）

这是我的xml代码：

}

所以，如果我的代码中出现问题，是否有任何建议？

非常感谢。

答案 0 :(得分：0)

尝试从Java部分调用方法，不要使用android：onClick

从xml调用

在共享偏好中使用按钮（购买）状态的默认值为false。

并在此屏幕中将oncreate（）方法中的 if 检查实现为：

if(button(buy) state ==false)
{
 //make button(buy) state enable
 //make activity button state disable
}
else
{
//make button(buy) state disable
//make activity button state enable
}

根据应用购买后的结果，使按钮（购买）和活动调用按钮状态为真/假，并根据结果更新共享的prefrence状态
