如何在 TextInputLayout unfocus 中更改边框和颜色？

<com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"
        android:layout_height="wrap_content"
        app:boxStrokeWidth="4dp"
        app:boxStrokeColor="@color/colorPrimary"
        app:layout_constraintTop_toBottomOf="@id/a">

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:hint="@string/app_name"
            android:textColorHint="@color/colorPrimary"
            android:layout_height="wrap_content"/>
    </com.google.android.material.textfield.TextInputLayout>

我试试:

app:boxStrokeWidth="4dp"
app:boxStrokeColor="@color/colorPrimary"

但是，不能在不专心的情况下工作

如果你想在聚焦/非聚焦模式下有不同的笔划宽度，你可以使用 boxStrokeWidth 和 boxStrokeWidthFocused 属性。

<!-- The value to use for the box's stroke when in outline box mode, 
     or for the underline stroke in filled mode. -->
<attr format="dimension" name="boxStrokeWidth"/>
<!-- The value to use for the focused box's stroke when in outline box mode,
     or for the focused underline stroke in filled mode.. -->
<attr format="dimension" name="boxStrokeWidthFocused"/>

类似于:

    <com.google.android.material.textfield.TextInputLayout
        app:boxStrokeWidthFocused="4dp"
        app:boxStrokeWidth="1dp"
        app:boxStrokeColor="@color/text_input_layout_stroke_color"
        ..>

对于描边颜色，您可以定义一个选择器，例如:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:color="@color/..." android:state_focused="true"/>
  <item android:alpha="0.87" android:color="@color/..." android:state_hovered="true"/>
  <item android:color="@color/.." android:state_enabled="false"/>
  <item android:color="@color/..."/> <!--unfocused-->
</selector>

注意:boxStrokeWidthFocused 至少需要 1.2.0-alpha04 版本。
