推荐答案
看起来您的转换错误:java.lang.ClassCastException:android.support.design.widget.TextInputEditText无法转换为android.support.design.widget.TextInputLayout
It looks like you have wrong casting: java.lang.ClassCastException: android.support.design.widget.TextInputEditText cannot be cast to android.support.design.widget.TextInputLayout
检查在xml和代码中是否使用相同的类型,可能它们是不同的.
Check if you use the same types in xml and in your code, probably they are different.
