我正在尝试创建一个基本的联系表单应用程序，人们可以在其中填写所需信息并按下发送按钮并将信息发送到特定的电子邮件。我把它放在一起但由于某种原因它不起作用。 Java文件中包含来自类似应用程序的代码。 Java文件中有spinner代码，所以我把它变成了笔记..不确定它是不是搞乱了。这是代码，请让我知道我可以做些什么来使它工作。
activity_main.xml中：

我现在正在显示该表单，但您输入的信息未发送到该电子邮件。我被提示屏幕指示我应该使用哪个电子邮件服务来执行此应用程序。我只是希望输入的信息直接发送到应用程序中提供的电子邮件。
提前致谢！
答案 0 :(得分：0)
您正在看到包含电子邮件客户端列表的屏幕，因为这是Intents的工作方式。
意图不会直接执行您想要的操作，它只能将数据移交给另一个可以处理数据的Activity（可能在不同的应用程序中）。
