删除 AutoCompleteTextView 下拉列表分隔符

问题描述

在我的应用程序中，我使用 AutoCompleteTextView.要求之一是隐藏分隔线.我已将 AutoCompleteTextView 添加到布局中:

In my application, I'm using AutoCompleteTextView.One of the requirements is to hide the divider.I have added AutoCompleteTextView to layout:

 <AutoCompleteTextView
android:id="@id/address_bar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="15dp"
android:layout_marginRight="8dp"
android:layout_toLeftOf="@id/address_operation_btn"
android:background="@null"
android:completionThreshold="1"
android:dropDownAnchor="@id/anchor"
android:dropDownVerticalOffset="13dp"
android:dropDownWidth="wrap_content"
android:ellipsize="end"
android:gravity="center"
android:layout_centerHorizontal="true"
android:hint="@string/address_bar_hint"
android:imeOptions="actionGo"
android:inputType="textUri"
android:maxLines="1"
android:saveEnabled="true"
android:singleLine="true"
android:dropDownListViewStyle="@style/searchResultsList"
android:textColor="@android:color/white"
android:textColorHint="#80FFFFFF"
android:textSize="17sp" />

我使用的样式是

    <style name="searchResultsList" parent="@android:style/Widget.ListView">
    <item name="android:divider">@android:color/transparent</item>
    <item name="android:dividerHeight">0px</item>
</style>

但是分隔线还在那里...如果可以隐藏怎么办?

But the divider is still there...How if can be hidden?

推荐答案

用您的应用程序主题覆盖它.在你的 themes.xml

Override it with your application theme. In your themes.xml

<style name="AppTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
  <item name="android:dropDownListViewStyle">@style/DropDownListViewStyle</item>
</style>

<style name="DropDownListViewStyle" parent="@style/Widget.AppCompat.ListView.DropDown">
  <item name="android:divider">@android:color/transparent</item>
  <item name="android:dividerHeight">0dp</item>
</style>
