Webview加载本地js、图片的方法_html/css_WEB-ITnose
在项目开发中经常会将比较大的js、图片、css等放到app中,而html放服务器,这样在使用时流量较少,加载也比都放服务器上快,其实方法也比较多,网上搜了很久都没结果。
一种是获取服务器返回的html内容后,直接处理返回的html,在引用js、图片的地方替换其资源为本地的“file:///android_asset/”资源,这种方式我没试。
另一种就是直接使用WebViewClient实现
1 webView.setWebViewClient(new WebViewClient(){ 2 @Override 3 public WebResourceResponse shouldInterceptRequest(WebView view, String url) { 4 WebResourceResponse response = null; 5 6 response = super.shouldInterceptRequest(view,url); 7 if (url.contains("m.css")){ 8 try { 9 response = new WebResourceResponse("text/css","UTF-8",getAssets().open("css/m.css"));10 } catch (IOException e) {11 e.printStackTrace();12 }13 }14 return response;15 }16 });
注意最好是使用if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)来区分下版本执行的代码

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.

The role of HTML is to define the structure and content of a web page through tags and attributes. 1. HTML organizes content through tags such as , making it easy to read and understand. 2. Use semantic tags such as, etc. to enhance accessibility and SEO. 3. Optimizing HTML code can improve web page loading speed and user experience.
