MainActivity.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

<android.support.design.widget.TabLayout
        android:id="@+id/sliding_tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
/>
<android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0px"
        android:layout_weight="1"
        android:background="@color/white" />

</LinearLayout>

我已尝试将AppBase主题设置为AppCompat，但它没有帮助。

Answer 1

不知道这是否与您的问题有关。我将TabLayout和ViewPager的标签更改为与该页面上的标签相对应的标签：https://material.io/develop/android/components/tab-layout/

这是我的应用中的代码，它使错误消失了：

<com.google.android.material.tabs.TabLayout
    android:id="@+id/sliding_tabs"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabMode="fixed"/>

<androidx.viewpager.widget.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="match_parent"
    android:layout_height="0px"
    android:layout_weight="1"
    android:background="@android:color/white" />

Answer 2

我也遇到过类似的问题。经过一些问题的研究，我找到了解决方案。为tablayout添加另一个样式资源。

我也在我的博客上描述过它。

http://www.geeksmember.blogspot.in/2015/10/errorerror-inflating-class.html

将其添加到您的values-v21 / styles.xml中。如果您没有值-v21文件夹，请在app / res文件夹中创建一个。然后在该文件夹中创建styles.xml文件。

    <resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="AppTheme.Base"/>
    <!-- inherit from the material theme -->
    <style name="AppTheme.Base" parent="android:Theme.Material">
        <!-- colorPrimary is used for the default action bar background -->
        <item name="android:colorPrimary">#3F51B5</item>

        <!-- colorPrimaryDark is used for the status bar -->
        <item name="android:colorPrimaryDark">#303F9F</item>

        <!-- colorAccent is used as the default value for colorControlActivated
             which is used to tint widgets -->
        <item name="android:colorAccent">#FF4081</item>
    </style>

    <style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
        <item name="tabIndicatorColor">#FF4081</item>
    </style>
</resources>

然后将自定义样式属性添加到您的tablayout。

<android.support.design.widget.TabLayout
        android:id="@+id/sliding_tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        style="@style/MyCustomTabLayout"
/>

我也面临同样的问题，这就像一个魅力。

Answer 3

我也遇到了同样的错误。我通过替换来解决了问题

此代码出错

<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    app:layout_constraintEnd_toEndOf="parent"
    app:tabMode="scrollable"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="@+id/viewpager" />

<android.support.v4.view.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="0dp"
    android:layout_height="0dp"

    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

使用此代码可解决上述问题

<com.google.android.material.tabs.TabLayout
    android:id="@+id/tab_layout"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginBottom="4dp"
    android:background="?attr/colorPrimary"
    app:layout_constraintBottom_toTopOf="@+id/viewpager"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<androidx.viewpager.widget.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="wrap_content"
    android:layout_height="0dp"
    android:layout_marginEnd="5dp"
    android:layout_marginBottom="3dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/tab_layout" />

**如果您使用的是androidx，则无需将 android.support.design.widget.TabLayout 更改为 com.google.android.material.tabs.TabLayout * *

Answer 4

我也遇到了同样的错误。我通过升级 android.support 解决了这个问题 com.android.support:design:24.1.0

到

com.android.support:design:28.0.0

扩展类android.support.design.widget.TabLayout时出错
