让安卓APP嵌入网页，只需要编辑四个文件即可，即activity\_main.xml，MainActivity.java，styles.xml，AndroidManifest.xml

主页界面采用线性布局，放一个WebView

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

主程序添加初始化页面（initView）和重写点击返回按钮的监听（onKeyDown）

MainActivity.java

package com.lamcy.page;
    
    import android.app.Activity;
    import android.os.Build;
    import android.os.Bundle;
    import android.view.KeyEvent;
    import android.webkit.WebSettings;
    import android.webkit.WebView;
    import android.webkit.WebViewClient;
    
    public class MainActivity extends Activity {
        private WebView web;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            initView();
        }
    
        private void initView() {
    
            web = (WebView) findViewById(R.id.web);
            web.getSettings().setJavaScriptEnabled(true);
    
            web.setWebViewClient(new WebViewClient() {
                @Override
                public boolean shouldOverrideUrlLoading(WebView view, String url) {
                    view.loadUrl(url);
                    return true;
                }
            });
    
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                web.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
            }

web.getSettings().setUseWideViewPort(true); //将图片调整到适合webview的大小
          web.getSettings().setLoadWithOverviewMode(true); // 缩放至屏幕的大小
          web.getSettings().setLoadsImagesAutomatically(true); //支持自动加载图片

web.loadUrl( "https://blog.csdn.net/zq33312757/article/details/80401165"); \} @Override  public boolean  onKeyDown( int keyCode , KeyEvent event) \{ if (keyCode == KeyEvent. *KEYCODE\_BACK* && web.canGoBack()) \{ web.goBack() ;  return true; \} return super.onKeyDown(keyCode , event) ; \}\}

样式文件添加NoActionBar，将地址工具栏和页面标题取消掉。

styles.xml

<resources>
        
        <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
            
            <item name="colorPrimary">@color/colorPrimary</item>
            <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
            <item name="colorAccent">@color/colorAccent</item>
        </style>
        <style name="AppTheme.NoActionBar">
            <item name="windowActionBar">false</item>
            <item name="windowNoTitle">true</item>
        </style>
    </resources>

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.lamcy.page" >
        <uses-permission android:name="android.permission.INTERNET" />
        <uses-permission android:name="android.permission.WRITE_SETTINGS" />
        <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:supportsRtl="true"
            android:theme="@style/AppTheme" >
            <activity android:name=".MainActivity"
                android:exported="true"
                android:launchMode="singleTask"
                android:screenOrientation="portrait"
                android:theme="@style/AppTheme.NoActionBar"
                android:windowSoftInputMode="adjustPan">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
    </manifest>
