java - SmsManager 在发送每条短信之间有延迟

Question

早上好，感谢并抱歉我的英语!

我正在开发一个 Android 应用程序，我希望该应用程序使用 SmsManager 发送大量短信。这很好，但是当我尝试在每条短信的发送之间实现任何类型时，问题就出现了。我也尝试在 for、asynctask 中使用线程，但应用程序也进入休眠状态，并且我需要应用程序在发送短信时不会阻塞。

我读取外部(应用程序目录内)文件的编号，然后将这些数据放入哈希表中，然后执行 for 循环来调用 SmsManager 函数 sendTextMessage。

最后，我成功解决了这个问题。我使用了 Handler 和 Thread 以及进度条。
