android webview调用js滚动到指定位置

一、activity

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import com.tencent.smtt.sdk.WebView
import com.tencent.smtt.sdk.WebViewClientclass MainActivity : AppCompatActivity() {private lateinit var webView: WebViewoverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_main)webView = findViewById(R.id.webView)webView.settings.javaScriptEnabled = true // 启用JavaScriptwebView.webViewClient = object : WebViewClient() {override fun onPageFinished(view: WebView?, url: String?) {super.onPageFinished(view, url)// 页面加载完成后，执行JavaScript来滚动到指定的divscrollToDiv("targetDiv")}}webView.loadUrl("https://www.example.com")}private fun scrollToDiv(divId: String) {// 执行JavaScript，滚动到指定的divwebView.evaluateJavascript("document.getElementById('$divId').scrollIntoView();", null)}
}

二、XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context=".MainActivity"><com.tencent.smtt.sdk.WebViewandroid:id="@+id/webView"android:layout_width="match_parent"android:layout_height="match_parent" /></LinearLayout>
