在新的android.support.design.widget.TabLayout中自定义选定的选项卡颜色？

Question

我想知道是否可以在新设计tablayout中更改选定的标签颜色？我找到了所选标签文字颜色的解决方案，但我想知道更改标签颜色本身。

    

    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        style="@style/TabLayout.Theme"
        android:layout_alignParentTop="true"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_below="@+id/tabs"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</RelativeLayout>





<style name="TabLayout.Theme" parent="Widget.Design.TabLayout">
        <item name="tabIndicatorColor">@color/black</item>
        <item name="tabIndicatorHeight">4dp</item>
        <item    name="tabTextAppearance">@style/TextAppearance.Jacksonville.Tab</item>
        <item name="tabSelectedTextColor">@color/text_dim</item>
        <item name="tabBackground">@color/color_heading</item>
    </style>

我需要像这样更改选定的标签颜色。

Answer 1

您可以使指示器的高度等于tablayout的高度，以便指示器覆盖标签布局中所选项目的所有尺寸

 <style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">

        <!-- the color you want in selected tab -->
        <item name="tabIndicatorColor">#50000000</item>
        <item name="tabTextAppearance">@style/MyCustomTabTextAppearance</item>

           <!-- set the indicator hieght equal to tablayout height -->
        <item name="tabIndicatorHeight">60dp</item>
        <item name="tabSelectedTextColor">#222222</item>

Answer 2

您只需设置app:tabBackground属性

即可

app:tabBackground="@drawable/tab_selector_color"

并创建一个可绘制的文件tab_selector_color.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/tab_selected" android:state_selected="true"/>
    <item android:drawable="@color/tab_unselected"/>
</selector>

所以完整的xml代码看起来像

 <android.support.design.widget.TabLayout
        android:id="@+id/sliding_tabs"
        android:layout_width="match_parent"
        android:layout_height="android:attr/listPreferredItemHeight"
        android:minWidth="0dp"
        app:tabMaxWidth="0dp"
        app:tabGravity="fill"
        app:tabMode="fixed"
        app:tabTextColor="@color/white"
        app:tabIndicatorHeight="0dp"
        app:tabSelectedTextColor="@color/white"
        app:tabIndicatorColor="@color/mainBlue"
        app:tabBackground="@drawable/tab_color_selector"/>
