您可以使用自定义样式进行设置：

    <com.google.android.material.textfield.TextInputLayout
        style="@style/MyTextInputLayout"

定义选择器：

  <style name="MyTextInputLayout " parent="Widget.MaterialComponents.TextInputLayout.FilledBox" >    
   <item name="android:textColorHint">@color/my_selector</item>.  
  </style>

与：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:alpha="0.38" android:color="@color/colorSecondaryLight" android:state_enabled="false"/>
    <item android:alpha="0.6" android:color="@color/colorPrimary"/>
</selector>

    TextInputLayout textInputLayout = findViewById(R.id.til);                   
    textInputLayout.setDefaultHintTextColor
      (ContextCompat.getColorStateList(this,R.color.selector));
