Question

我在Android浏览器项目上工作

许多网站都使用GIF动画和广告。我如何在android webview中禁用GIF动画？

Answer 1

只需注入一个javascript，即可在网页完成加载后递归冻结gif。你是怎么做的，

首先将此javascript复制到您的assets文件夹（如果文件夹不可用然后在res目录中创建文件夹） - gif_freezer.js
在班级中添加此方法

private void injectScriptFile(WebView view, String scriptFile) {
        InputStream input;
        try {
            input = getAssets().open(scriptFile);
            byte[] buffer = new byte[input.available()];
            input.read(buffer);
            input.close();

        String encoded = Base64.encodeToString(buffer, Base64.NO_WRAP);
        view.loadUrl("javascript:(function() {" +
                "var parent = document.getElementsByTagName('head').item(0);" +
                "var script = document.createElement('script');" +
                "script.type = 'text/javascript';" +
                // Tell the browser to BASE64-decode the string into your script !!!
                "script.innerHTML = window.atob('" + encoded + "');" +
                "parent.appendChild(script)" +
                "})()");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


}

在String encoded = Base64.encodeToString(buffer, Base64.NO_WRAP); view.loadUrl("javascript:(function() {" + "var parent = document.getElementsByTagName('head').item(0);" + "var script = document.createElement('script');" + "script.type = 'text/javascript';" + // Tell the browser to BASE64-decode the string into your script !!! "script.innerHTML = window.atob('" + encoded + "');" + "parent.appendChild(script)" + "})()"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }方法内放置代码，
```
onPageFinished
```
