更改项目之间的ActionBarTab行

Question

我正在开发Android项目，我无法改变的是Tab项之间的界限。现在它是浅白色/灰色，但我想让它变成黑色。我试图将ActionBar.Solid.A的样式改为背景为黑色，但它并没有解决问题。在我提出问题之前，我已经检查了几个类似的问题，但没有找到解决方案......

Answer 1

您想要更改的是ActionBarTab分隔线颜色。你可以这样做：

在ActionBarTabStyle.A内定义中，添加：

<item name="android:actionBarDivider">@drawable/tab_divider</item>

tab_divider drawable也是一个XML文件：

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="90"
    android:toDegrees="90" >

    <shape android:shape="line" >
        <stroke
            android:dashWidth="3dp"
            android:width="4dp"
            android:color="@android:color/black" />
    </shape>

</rotate>

修改：另一种解决方案是直接更改Theme.A主题，添加：

<item name="actionBarDivider">@android:color/black</item>

请注意，未使用android：前缀。
