我有一个包含很多EditText的应用程序，我想创建一个向它们添加错误的函数，例如，如果是特定的EditText.lenght() == 0，那么它必须设置错误"Error, field must not be empty"左右。
我尝试了什么
我有一个功能：
fun errorEmpty(et: EditText) {
if(et.length() > 0)
et.error = null
else {
et.error = "Error, field must not be empty"
et.requestFocus()
}
}
这个打破了应用程序：
var et = someEditText
errorEmpty(et)
这是最后一个的日志

这个没有做任何事情（它不会破坏应用程序）：
errrorEmpty(someEditText)
提前致谢！
编辑：
我也尝试过：
fun errorEmpty(et: EditText): EditText {
if(et.length() > 0)
et.error = null
else {
et.error = "Error, field must not be empty"
et.requestFocus()
}
}return et
然后将结果分配给EditText：
et = errorEmpty(et)
它也打破了应用程序，这是日志：
