最近开发一个需要未联网功能的App, 不熟悉使用Java原生开发界面，于是想使用本地H5做界面，本文测试了使用本地html加载远程数据。直接上代码：
MainActivity.java
package com.alex.webviewlocal;import androidx.appcompat.app.AppCompatActivity;import android.os.Build;
import android.os.Bundle;
import android.webkit.CookieManager;
import android.webkit.WebResourceRequest;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;public class MainActivity extends AppCompatActivity {private WebView webView;private String url="file:///android_asset/web/index.html";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);webView = findViewById(R.id.webview);WebSettings webSettings = webView.getSettings();CookieManager cookieManager = CookieManager.getInstance();cookieManager.setAcceptCookie(true);webSettings.setJavaScriptEnabled(true); // 设置支持javascriptwebSettings.setUseWideViewPort(true); // 将图片调整到适合webview的大小webSettings.setLoadWithOverviewMode(true); // 缩放至屏幕的大小webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);webSettings.setUserAgentString("User-Agent");webSettings.setLightTouchEnabled(true); // 设置用鼠标激活被选项webSettings.setBuiltInZoomControls(true); // 设置支持缩放webSettings.setDomStorageEnabled(true); //设置DOM缓存，当H5网页使用localstorage时，一定要设置webSettings.setDatabaseEnabled(true);webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE); // 设置去缓存，防止加载的为上一次加载的数据webSettings.setSupportZoom(true); // 设置支持变焦webView.setHapticFeedbackEnabled(false);webSettings.setPluginState(WebSettings.PluginState.ON);webSettings.setAllowFileAccess(true);webSettings.setAllowContentAccess(true);webSettings.setAllowUniversalAccessFromFileURLs(true);webSettings.setAllowFileAccessFromFileURLs(true);webView.loadUrl(url);// try{
// if(Build.VERSION.SDK_INT>=16){
// Class<?> clazz = webView.getSettings().getClass();
// Method method = clazz.getMethod(
// "setAllowUniversalAccessFromFileURLs", boolean.class);
// if(method!=null){
// method.invoke(webView.getSettings(),true);
// }
// }
// } catch (NoSuchMethodException e) {
// throw new RuntimeException(e);
// } catch (InvocationTargetException e) {
// throw new RuntimeException(e);
// } catch (IllegalAccessException e) {
// throw new RuntimeException(e);
// }
//
// webView.loadUrl(url);
// webView.setWebViewClient(new WebViewClient(){
// @Override
// public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
// return super.shouldOverrideUrlLoading(view, request);
// }
// });}
}
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical">

</LinearLayout>
h5 文件
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>Document</title><script src="./vue.min.js"></script><script src="./axios.min.js"></script>
</head>
<body><div id="app"><h2>{{message}}</h2><ul><li v-for="user in users" :key="user.id">{{user.name}}</li></ul></div><script>var app = new Vue({el:'#app',data(){return {message:'Hello Vue!',users:[]}},mounted(){axios.get('https://jsonplaceholder.typicode.com/users').then(response => {this.users = response.data}).catch(error => {console.log(error)})}})</script>
</body>
</html>
