【完美】安卓开发网页嵌入式套壳

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"?>
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

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

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


    
    
    

AndroidManifest.xml

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