在Android 5.1设备上运行包含WebView的布局时，遇到InflateException错误。问题出在layout的XML文件中。通过将android.webkit.WebView的引用从<WebView/>更改为<android.webkit.WebView/>解决了问题，但使用<WebView app:layout_behavior="@string/appbar_scrolling_view_behavior"/>会导致错误持续存在。

问题描述

只是在 layout 中引入了 WebView ，然后在 Activity 中写了setContentView()，在 Android 5.1 的机子运行时就出现了错误。
代码如下：
activity_main.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"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".webviewtest.Main18Activity">

    <WebView
        android:id="@+id/web_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

MainActivity.java

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import com.example.myapplication.R;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

报错如下：

解决方案

将 app 目录下的 build.gradle 文件里的
implementation 'androidx.appcompat:appcompat:1.1.0'
修改为
implementation 'androidx.appcompat:appcompat:1.0.2'
经测试，修改为 版本 1.2.0-alpha01 仍然会出现错误。
