Web控件

Android开发之Web控件介绍（小白）

效果图：Test01，简单加载网站

效果图：Test02，自己利用html语句编写

需要修改两个地方，如下：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.newworld" >

    <uses-permission android:name="android.permission.INTERNET" />

    <application
    	android:usesCleartextTraffic="true"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.Newworld">
        <activity
            android:name=".web.WebActivity"
            android:exported="true" />

        <provider
            android:name=".YourContentProvider"
            android:authorities="cn.com.you"
            android:enabled="true"
            android:exported="true" >
        </provider>

        <activity
            android:name=".MainActivity2"
            android:exported="true" />
        <activity
            android:name=".MainActivity"
            android:exported="true" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

package com.example.newworld.web;

import android.webkit.WebView;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;

public class WebActivity extends AppCompatActivity {

    public WebView showweb;

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

        /**
         * Test01:加载http://www.4399.com/页面（其实是经过浏览器解析后的xml
         */
        //showweb.loadUrl("http://www.4399.com/");

        /**
         * Test02:自创页面
         */
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("<div>学习课程</div>");
        stringBuilder.append("<ul>");
        stringBuilder.append("<li>学习课程</li>");
        stringBuilder.append("<li>学习课程2</li>");
        stringBuilder.append("<li>学习课程3</li>");
        stringBuilder.append("</ul>");
        showweb.loadDataWithBaseURL(null,stringBuilder.toString(),"text/html","utf-8",null);

    }

    /**
     * 初始化模块
     */
    public void init(){
        showweb = findViewById(R.id.showweb);
    }
}
