【问题描述】：

当我的暴露下拉菜单被激活时，我在尝试更改其下划线和浮动标签的颜色时遇到问题。我填充的暴露下拉菜单的“colorControlActivated”目前是蓝绿色。无论我在样式文件中指示什么（黑色），我的 registerOrderName 菜单仍将使用 colorPrimary 颜色作为 colorControlActivated。在我的样式文件中

    <!-- Legacy TextField Theme-->
    <style name="TextInputLayoutAppearance" parent="Widget.Design.TextInputLayout">
        <item name="colorControlNormal">@color/textPlaceholderColor</item>
        <item name="colorControlActivated">@color/textFieldColor</item>
        <item name="colorControlHighlight">@color/textFieldColor</item>
    </style>

    <!-- TextField Hint Theme-->
    <style name="TextInputLayoutHintText">
        <item name="android:textColor">@color/textPlaceholderColor</item>
        <item name="android:textSize">16sp</item>
    </style>

    <!-- Legacy Drop Down Menu Theme-->
    <style name="MenuLayoutAppearance" parent="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu">
        <item name="colorControlNormal">@color/textPlaceholderColor</item>
        <item name="boxBackgroundColor">@color/white</item>
        <item name="colorControlActivated">@color/textFieldColor</item>
        <item name="colorControlHighlight">@color/textFieldColor</item>
    </style>

    <style name="Autocomplete">
        <item name="colorControlActivated">@color/textFieldColor</item>
        <item name="colorControlHighlight">@color/textFieldColor</item>
    </style>

在我的 activity.xml 文件中

            android:id="@+id/registerTextInputLayout4"
            style="@style/MenuLayoutAppearance"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginStart="20dp"
            android:layout_marginTop="10dp"
            android:layout_marginEnd="20dp"
            android:elevation="12dp"
            app:hintTextAppearance="@style/TextInputLayoutHintText"
            app:layout_constraintEnd_toEndOf="@+id/registerForm"
            app:layout_constraintStart_toStartOf="@+id/registerForm"
            app:layout_constraintTop_toBottomOf="@+id/registerTextInputLayout3">

            <androidx.appcompat.widget.AppCompatAutoCompleteTextView
                android:id="@+id/registerOrderName"
                android:theme="@style/Autocomplete"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:fontFamily="@font/open_sans"
                android:hint="@string/RegisterForm4"
                android:paddingStart="0dp"
                android:paddingEnd="0dp"
                android:singleLine="true"
                android:textColor="@color/textFieldColor"
                android:textCursorDrawable="@drawable/cursor_color"
                android:textSize="18sp" />

        </com.google.android.material.textfield.TextInputLayout>

在我的颜色文件中

    <color name="colorPrimary">#00BEBA</color>
    <color name="colorPrimaryDark">#00BEBA</color>
    <color name="colorAccent">#F60606</color>
    <color name="white">#FFFFFF</color>

    <color name="textFieldColor">#000000</color>
    <color name="textFieldCursorColor">#FB0000</color>
    <color name="textFieldHightLightColor">#2196F3</color>

    <color name="facebookBlue">#3B5998</color>

【解决方案1】：

您可以使用android:theme 属性覆盖colorPrimary：

   <com.google.android.material.textfield.TextInputLayout
        style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu"
        android:theme="@style/InputText_Overlay"
        ..>

           <AutoCompleteTextView
             android:layout_width="match_parent"
             android:layout_height="wrap_content">

  </com.google.android.material.textfield.TextInputLayout>

与：

<style name="InputText_Overlay">
    <item name="colorPrimary">@color/....</item>
</style>
