比如有一个图片xxxxx.png，这个图片已经放在了assets中，现在加载了一个外部html，就需要直接把assets里面的图片拿出来加载而不需要重新从网络获取。当然可以在html里面将图片链接换成file:///android_asset/xxxxx.png,
但是这样这个html就不能在Android ,ios,WAP中公用了。
| webView.setWebViewClient(new WebViewClient() { @Override public WebResourceResponse shouldInterceptRequest(WebView view, String url) { WebResourceResponse response = null; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){ response = super.shouldInterceptRequest(view,url); if (url.contains("xxxxx.png")){ try { response = new WebResourceResponse("image/png","UTF-8",getAssets().open("xxxxx.png")); } catch (IOException e) { e.printStackTrace(); } } } // return super.shouldInterceptRequest(view, url); return response; } @TargetApi(Build.VERSION_CODES.LOLLIPOP) @Override public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) { WebResourceResponse response = null; response = super.shouldInterceptRequest(view, request); if (url.contains("xxxxx.png")){ try { response = new WebResourceResponse("image/png","UTF-",getAssets().open("xxxxx.png")); } catch (IOException e) { e.printStackTrace(); } } return response; } } |
