Webview内嵌在ScrollView中的底部空白和滑动冲突

重新计算Webview的内容高度，并设置到Webview

@JavascriptInterfacepublic void resize(final float height) {runOnUiThread(new Runnable() {@Overridepublic void run() {//Toast.makeText(getActivity(), height + "", Toast.LENGTH_LONG).show();//此处的 layoutParmas 需要根据父控件类型进行区分，这里为了简单就不这么做了webView.setLayoutParams(new FrameLayout.LayoutParams(getResources().getDisplayMetrics().widthPixels, (int) (height * getResources().getDisplayMetrics().density)));}});}

主动调用：

webView.setWebViewClient(new WebViewClient() {@Overridepublic void onPageFinished(WebView view, String url) {

	//获取html可见的高度，会有出错webView.loadUrl("javascript:App.resize(document.body.getBoundingClientRect().height)");

//获取第一个快元素的高度，效率更好

webView.loadUrl("javascript:App.resize(document.getElementsByTagName('div')[0].scrollHeight)");

//别忘了设置webview支持javascript

WebSettings settings = webView.getSettings();settings.setJavaScriptEnabled(true);
