无法在 Android 中设置 ListView Divider 颜色
Unable to set ListView Divider color in Android
我有一个 activity,里面有一个 ListView。我已使用 android:divider="#000000"
属性将 ListView 分隔线的颜色设置为黑色,并将分隔线高度设置为 1dp。由于某种原因,分隔线显示为蓝色而不是黑色。这是我的 xml。任何帮助将不胜感激。

使用android:background代替android:divider

android:layout_width="match_parent"
android:layout_height="match_parent"

我在 styles.xml
:
中为 ListViews 设置了样式
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
...
<style name="ListViews" parent="@android:style/Widget.ListView">
<item name="android:cacheColorHint">@color/transparent</item>
<item name="android:divider">@drawable/list_divider</item>
<item name="android:dividerHeight">1px</item>
</style>
...
</resources>
我的 ListView 就这样使用了那个样式:
style="@style/ListViews"
显然,我的 drawable 文件夹中有这样的 drawable。
我的 list_divider.xml
可绘制对象是这样的:
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
>
<solid android:color="@color/navy_semi" />

显然,不要使用 @color/transparent
和 @color/navy_semi
,而是使用您自己的颜色。
这些仅在 my 颜色资源中定义。
在您的列表视图中使用以下属性。
android:cacheColorHint="@null"
如果没有任何效果,那么您可以创建自己的分隔线。
首先删除默认分隔符。
android:dividerHeight="0dp"

然后在您的 custom_row_layout.xml 中添加视图
