Android get height of webview content once rendered

Question

I\'m trying to get the height of a webview once it has been rendered. It always returns null, I\'ve tried getHeight, getMeasuredHeight, getCo

Answer 1

I chose this approach

const val heightWebViewJSScript = "(function() {var pageHeight = 0;function findHighestNode(nodesList) { for (var i = nodesList.length - 1; i >= 0; i--) {if (nodesList[i].scrollHeight && nodesList[i].clientHeight) {var elHeight = Math.max(nodesList[i].scrollHeight, nodesList[i].clientHeight);pageHeight = Math.max(elHeight, pageHeight);}if (nodesList[i].childNodes.length) findHighestNode(nodesList[i].childNodes);}}findHighestNode(document.documentElement.childNodes); return pageHeight;})()"

webView.webViewClient = object : WebViewClient() {

            override fun onPageFinished(view: WebView, url: String) {
                webView.evaluateJavascript(heightWebViewJSScript
                ) { height ->
                    val params = itemView.layoutParams
                    // params.height
                }
            }
        }
