Question

我正在使用谷歌提供的tablayout，除了未选择的标签指示符的颜色外，一切正常。我无法设置未选中的标签指示颜色。

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

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="fixed"
        style="@style/MyCustomTabLayout"

        />
</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" /> </android.support.design.widget.CoordinatorLayout>

Answer 1

尝试根据需要改变颜色：

在可绘制文件夹中创建此文件

<强> tab_indicator_color.xml ：

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- UNSELECTED TAB STATE -->
    <item android:state_selected="false" android:state_pressed="false">
        <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
            <!-- Bottom indicator color for the UNSELECTED tab state -->
            <item android:top="-5dp" android:left="-5dp" android:right="-5dp">
                <shape android:shape="rectangle">
                    <stroke android:color="#65acee" android:width="2dp"/>
                </shape>
            </item>
        </layer-list>
    </item>


</selector>

并在app：tabBackground中设置你的.xml文件之后：

 <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="fixed"
        style="@style/MyCustomTabLayout"
        app:tabBackground="@drawable/tab_indicator_color" />

Answer 2

**1.app:**

    tabBackground="@drawable/tablayout_selector"

**2.tablayout_selector.xml**

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/shl_common_default_color" />
        </shape>
    </item>
    <item>
        <inset android:insetBottom="1.5dp">
            <shape android:shape="rectangle">
                <solid android:color="@color/white" />
            </shape>
        </inset>
    </item>
</layer-list>


or

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/white" />
        </shape>
    </item>
    <item android:gravity="bottom">
        <shape android:shape="rectangle">
            <solid android:color="@color/shl_common_default_color" />
            <size android:height="1.5dp" />
        </shape>
    </item>
</layer-list>

对于使用新com.google.android.material.tabs.TabLayout的用户，如果您应用给出的解决方案，因为本文中的正确答案将使选项卡的所有四个角都出现

要解决此问题，请使用以下“ hack”

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- UNSELECTED TAB STATE -->
    <item android:state_selected="false" android:state_pressed="false">
        <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
            <!-- Bottom indicator color for the UNSELECTED tab state -->
            <item  android:top="-10dp" android:left="-1000dp" android:right="-1000dp">
                <shape android:shape="rectangle" >
                    <stroke android:color="#4cffffff" android:width="1dp"/>
                </shape>
            </item>
        </layer-list>
    </item>
</selector>
