android - 更改箭头颜色 Material ExposedDropdownMenu/TextInputLayout

Question

我想将箭头颜色更改为白色。怎么做？这是我的代码

<com.google.android.material.textfield.TextInputLayout
    style="@style/ExposedDropdownMenu"
    android:hint="Select"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <AutoCompleteTextView
        android:focusable="false"
        android:textSize="17sp"
        android:padding="15dp"
        android:textColorHint="@color/white"
        android:textColor="@color/white"
        android:id="@+id/actv_pool"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        tools:ignore="LabelFor" />

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

这是我的风格:

<style name="ExposedDropdownMenu" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu">
    <item name="boxStrokeColor">#fff</item>
    <item name="boxStrokeWidth">1dp</item>
    <item name="android:textColorHint">#fff</item>
</style>

我希望这很清楚。提前致谢。

您可以使用 app:endIconTint 布局中的属性:

 <com.google.android.material.textfield.TextInputLayout
            ...
            app:endIconTint="@color/my_selector_color">

或者您可以使用自定义样式:

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

和:

  <style  name="name="ExposedDropdownMenu" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu">
    <item name="endIconTint">@color/my_selector_color</item>
  </style>
