Flutter: how to enable gestures in a web view?

由 我是研究僧i 提交于 2020-02-01 09:17:23
问题 I would like to pinch in and out to zoom in my web view page in Flutter. I did some researches online and I found this somewhere: "Although pinch and zoom are built-in to WebView (Android) and UIWebView (iOS), they need to be "switched-on". In Android, the plugin needs to call the following: this.webView.getSettings().setBuiltInZoomControls(true); this.webView.getSettings().setSupportZoom(true); to allow pinch/zoom. In iOS, the plugin needs to call the following: self.webview.scalesPageToFit

android原生和H5交互(转)

由 自作多情 提交于 2020-02-01 09:11:28
最近在左一个Android原生的H5混合开发的APP，之前还没有好好的总结一下Android原生 和 Ｈ5 之间交互的方法，这里来总结一下： 1、hybrid通信，主要就是前端的js和我们Android端的通信 这是最基本JS和Java 的通信方式： 这里我们分四块来讲： （1）、js调用android原生的代码（不传递参数） （2）、js调用android原生的代码（传递参数） （3）、android原生调用JS的代码（不传递参数） （4）、android原生调用JS的代码（传递参数） 好的我们这里先来创建一个工程： 在工程的main文件夹下创建一个文件夹assets ,然后把写好的H5页面放入该文件夹中，H5页面代码如下： < pre name = " code " class = " html " > <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> < html xmlns = " http://www.w3.org/1999/xhtml " > < head > < meta http-equiv = " Content-Type " content = " text/html;

Android WebView加载网页失败异常处理

由 坚强是说给别人听的谎言 提交于 2020-01-29 04:15:02
开发过程中会遇到WebView加载失败的时候，会出现404、500、找不到网页等错误，页面显示系统默认的错误界面。系统默认界面难看，而且也会暴露网页地址不安全。所以我们需要对WebView加载失败或错误进行处理，自定义一个统一样式来加载失败的界面。 网页加载失败图 解决方案 我们可以自定义一个View用来展示加载失败的界面，也可以写一个错误展示的 Html让 WebView加载等。这里我们需要先重写 WebViewClient 的 onReceivedError() 和 WebChromeClient 的 onReceivedTitle() 方法。 Android 6.0以下处理方法： ① 判断 Html页面的标题中是否含有“Error”、“找不到网页”等信息； @Override public void onReceivedTitle(WebView view, String title) { super.onReceivedTitle(view, title); // android 6.0 以下通过title获取判断 if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) { if (title.contains("404") || title.contains("500") || title.contains("Error")
