TextInputLayout 导致设计问题

问：

每次我将 EditText 替换为 com.google.android.material.textfield.TextInputLayout 时，字段中的所有信息（在我的情况下，密码输入字段）都会消失，从某种意义上说，无论如何都需要提示，但实际上没有，他只是消失了。我想使用这个特定的工具，因为我想添加在字段中查看输入密码的功能，因为我自己经常遇到必须多次检查其拼写正确性的问题。

使用不带 TextInput 的 TextInput，只需 EditText

尝试添加实现“com.google.android.material：material：1.3.0-alpha01” 在 Gradle App 文件中，但它没有导致任何东西，它导致了错误，我不知道出于什么原因。我试图简单地将观察眼插入常规的 EditText 中 - 没有结果。因此，我想继续尝试使用它，但首先我需要修复它-_-
