build.gradle(Moudle.app)androidx的引用
implementation 'com.just.agentweb:agentweb-androidx:4.1.4'
布局的实现
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">
    //标题
    <include
        layout="@layout/activity_left_title_text_view"/>
    <LinearLayout
        android:id="@+id/view"
        android:orientation="vertical"
        android:layout_width="match_parent"

AndroidInterface类

js调android的监听方法
package com.dsy.jxih.iml
/** 
 *@Created by wrs on 2020/10/16,14:00

 */
interface JsInterfaceListener {
    fun jsPullUpMethod(method:String,params:String)
}
js调用android方法的实例
//callAndroid()是android端定义的方法
window.android.callAndroid();
window.android.callAndroid();记得  android区分大小写
android调用js方法的实例
mAgentWeb.getJsAccessEntrace().quickCallJs("androidpay");//androidpay()h5里的方法
