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>

我希望一切都清楚。提前致谢。

您可以在布局中使用app:endIconTint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"
    ...>

与：

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

Answer 2

只需使用

将 endIconTint 属性添加到 TextInputLayout

app:endIconTint="@color/primaryDarkColor"

哪里

@color/primaryDarkColor

是您想要的颜色选择

下面的示例带有完整的 XML 代码


        <com.google.android.material.textfield.TextInputLayout
            android:id="@+id/til_paying_bank"
            style = "@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/til_withdrawal_date"
            android:layout_centerHorizontal="true"
            android:padding="5dp"
            app:endIconTint="@color/primaryDarkColor">

            <AutoCompleteTextView
                android:id="@+id/actv_paying_bank"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="@string/paying_bank"
                android:dropDownSelector="@color/primaryLightColor"
                />

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

如果你想改变drawable，不仅仅是颜色，你可以设置endIconDrawable。对于 drawable 放一个选择器 xml 像这样：

    <selector xmlns:android="http://schemas.android.com/apk/res/android">

      <item android:drawable="@drawable/ic_page_up" android:state_checked="true"/>
      <item android:drawable="@drawable/ic_page_down"/>
    </selector>
