Android 应用内购买 - 无法从 onBillingSetupFinished() 事件调用按钮 setText()

Question

我有一个应用程序内购买功能，我认为遵循标准流程，但遇到了与按钮 setText() 更新相关的奇怪问题的挑战。\n这是我想要做的：

\n

\n
1. 启动计费连接
\n
2. 成功连接/onBillingSetupFinished()我加载 SKus 并希望在按钮中显示价格。\n这并不总是有效，而且调试起来很痛苦，因为 Toast.makeText() 方法不显示任何进度。但最终我可以在模拟器中登录 Google Play 后在模拟器中重现该问题。
\n

\n

setText(price)我注意到，如果我在下一行代码中执行按钮，则onBillingSetupFinished()不会执行。我在 logcat 中也没有看到任何内容。它在 后被卡住BillingClientStateListener-Setting Hard code price，永远不会到达BillingClientStateListener-DONE Setting Hard code price\n奇怪的是偶尔它会起作用，但大多数时候它不会。有什么指示可以指导我下一步应该做什么吗？

Answer 1

您需要从主线程更新 UI。

\n

解决方案代码：将其写入onBillingSetupFinished

\n

        requireActivity().runOnUiThread(new Runnable() {\n            @Override\n            public void run() {\n                btn100.setText("\xe2\x82\xb940.00");\n                btn250.setText("\xe2\x82\xb950.00");\n                btn700.setText("\xe2\x82\xb960.00");\n            }\n        });\n   \n
