Render Problems with TabLayout and ViewHolder

问题

I am currently unable to render an activity with just a TabLayout and ViewPager. I am getting this error:

Style ResourceReference{namespace=apk/res-auto, type=attr, name=textAppearanceButton} is not of type STYLE (instead attr)

From the following code:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".CompoundInterest">

    <com.google.android.material.tabs.TabLayout
        android:id="@+id/tabLayout"
        android:layout_width="409dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="86dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <com.google.android.material.tabs.TabItem
            android:id="@+id/tabAbout"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="About" />

        <com.google.android.material.tabs.TabItem
            android:id="@+id/tabCalculator"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Calculator" />

    </com.google.android.material.tabs.TabLayout>

    <androidx.viewpager.widget.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@id/tabLayout" />
</androidx.constraintlayout.widget.ConstraintLayout>

I added the TabLayout and ViewPager to an otherwise blank, new layout and they have never rendered, even after being 'connected' to the fragments.

前往Android视图,找到Gradle Scripts - build.gradle(Module: App),然后进行编辑。

implementation &#39;com.google.android.material:material:1.9.0&#39;

更改为

implementation &#39;com.google.android.material:material:1.7.0&#39;

最后,点击与Gradle文件同步项目,等待一分钟,就可以了。

英文:

Go to the Android View, find the Gradle Scripts - build.gralde(Module :App) then edit it.
change

implementation &#39;com.google.android.material:material:1.9.0&#39;

to

implementation &#39;com.google.android.material:material:1.7.0&#39;

Finally, click Sync Project with Gradle Files, wait a minute, it would be fine.

有关版本1.8.0似乎存在问题。

其他Material Design示例
TabLayout中的TabItems也存在渲染问题。

降级到1.7.0可以正常工作。

英文:

There seems to be a problem with version 1.8.0.

Other Material Design examples
TabItems in TabLaout are also having rendering issues.

Downgrading to 1.7.0 works fine.
