我有以下代码，没有错误，只是这个无限循环......我没有得到问题所在 .
当我单击Button时，我想使用在edittexts中输入的值创建一个对象，并将它们传递给另一个activity..well ..但是我得到了那个循环 .
每个微调器都使用来自资源/字符串的字符串数组填充..我在这里获取值时遇到一些困难，因为在spinner spTipUtilizator中，当选择“Profesor”时，我希望禁用spGrupa，当“Student”是选中，我希望spdept被禁用，但这也行不通 . 并且基于该选项将选择下一个活动，该活动将在单击按钮后打开 .
另外，为什么在我的日历中设置默认日期不起作用？我在这里尝试了多个东西，但没有一个对我有用 . 我的Android Studio没有显示DatePicker，我知道更好用，只有那个Calendar，我不知道为什么会这样 .
