【问题描述】：

尝试创建一个智能手表应用程序，打开一个运行一些 JavaScript 代码的 Web 视图。我疯了：

Process: com.example.myapp.smartwatch, PID: 3308
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.myapp.smartwatch/com.example.myapp.smartwatch.MainActivity}: android.view.InflateException: Binary XML file line #0: Binary XML file line #0: Error inflating class android.webkit.WebView

这里是 MWE。

MainActivity.java：

package com.example.myapp.smartwatch;

import android.os.Bundle;
import android.support.wearable.activity.WearableActivity;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebViewClient;
import android.webkit.WebView;

import java.util.Arrays;

public class MainActivity extends WearableActivity {

    private WebView webview;

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

        // Prepare webview: add zoom controls and start zoomed out
        webview = (WebView) findViewById(R.id.webview);
        final WebSettings webSettings = webview.getSettings();
        webSettings.setJavaScriptEnabled(true);
        webSettings.setBuiltInZoomControls(true);
        webSettings.setSupportZoom(true);
        webSettings.setUseWideViewPort(true);
        webview.setWebChromeClient(new WebChromeClient());
        webview.setInitialScale(1);

        webview.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                // after the HTML page loads, run JS to initialize graph
                int dataset[] = new int[] {5,10,15,20,35};
                String text = Arrays.toString(dataset);

                webview.loadUrl("javascript:initGraph(" + text + ", " +(webview.getHeight()) + ", " + (webview.getWidth()) + ")");
            }
        });

        // Load base html from the assets directory
        webview.loadUrl("file:///android_asset/html/graph.html");
    }
}

activity_main.xml：

?xml version="1.0" encoding="utf-8"?>

<android.support.wear.widget.BoxInsetLayout
    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:background="@color/dark_grey"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.myapp.smartwatch.MainActivity"
    tools:deviceIds="wear"
    android:padding="@dimen/box_inset_layout_padding">


        <WebView
            android:id="@+id/webview"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentBottom="true"/>

</android.support.wear.widget.BoxInsetLayout>

这是我得到的完整错误：

我已经检查了有关此错误的其他线程，但我对 xml 文件错误上的“第 0 行”特别感到困惑。有人知道为什么会这样吗？

提前致谢

【问题讨论】：

标签： android xml android-studio webview

【解决方案1】：

Android Wear does not support WebView.

更具体地说，检查原始异常：

Caused by: java.lang.UnsupportedOperationException
    at com.android.webview.nullwebview.NullWebViewFactoryProvider.createWebView(NullWebViewFactoryProvider.java:42)

自 Android 4.4 或更高版本以来，WebView 由“System WebView”应用程序提供，这意味着当您请求显示 @987654326 时，Android 必须做一些调整才能掌握 WebView 实现的胆量@。在这里，NullWebViewFactoryProvider 的意思是“我们没有要使用的系统 WebView”。

【讨论】：

该死！那我怎么能找到智能手表的网络浏览器呢？在这种情况下有什么解决方法的想法吗？
将其包装在布局中（线性或相对...）可以解决问题吗？
@LBes：“在这种情况下有什么解决方法的想法吗？”——支持 JavaScript 吗？没有头绪，对不起。对于基本的无样式 HTML，Html.fromHtml() 和 TextView 有效。
@CommonsWare 接受了您的回答！抱歉，我好像忘记了
