java - 将 Spinners 的文本发送到邮件

Question

我刚开始在 android studio 中学习编码.....我有这个小问题想解决!我想从 spinners 和 editText 获取文本并将其放入邮件正文!我已经学会了如何获取 editText 的文本并在邮件中获取它。我也只想添加微调器的文本，但我真的不知道该怎么做。这是我的 xml:

<?xml version="1.0" encoding="utf-8"?>

尝试这可能是因为您错过了对 String() 的调用

String message = staticSpinner.getSelectedItem().toString() +"and"+ dynamicSpinner.getSelectedItem().toString() + body.getText().toString();
