<!--        然并卵解决不了问题，boxStrokeColor其实用选择器就可以解决 未获取焦点的描边色问题-->
<!--        <item name="boxStrokeColor">@color/red</item>-->
        <item name="boxStrokeWidth">1dp</item>

white_textinputlayout_box_stroke_selector

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/white_no_night" android:state_activated="true"></item>
<item android:color="@color/white_no_night" android:state_focused="true"></item>

<item android:color="@color/white_transparency" android:state_hovered="false"></item>
<item android:color="@color/white_transparency" android:state_focused="false"></item>
</selector>

搞错，状态只支持如下

if (boxStrokeColorStateList.isStateful()) {
      defaultStrokeColor = boxStrokeColorStateList.getDefaultColor();
      disabledColor =
          boxStrokeColorStateList.getColorForState(new int[] {-android.R.attr.state_enabled}, -1);
      hoveredStrokeColor =
          boxStrokeColorStateList.getColorForState(
              new int[] {android.R.attr.state_hovered, android.R.attr.state_enabled}, -1);
      focusedStrokeColor =
          boxStrokeColorStateList.getColorForState(
              new int[] {android.R.attr.state_focused, android.R.attr.state_enabled}, -1);
    } else if (focusedStrokeColor != boxStrokeColorStateList.getDefaultColor()) {
      // If attribute boxStrokeColor is not a color state list but only a single value, its value
      // will be applied to the box's focus state.
      focusedStrokeColor = boxStrokeColorStateList.getDefaultColor();
    }

最后

<item android:color="@color/red" android:state_focused="false"></item>
<item android:color="@color/red" android:state_focused="false"></item>
<item android:color="@color/red" android:state_enabled="false"></item>
<item android:color="@color/themeColor" android:state_focused="true"></item>
<item android:color="@color/themeColor" android:state_hovered="true"></item>
