这个GIFDecoderview类是什么？ - sdabet

请参考以下问题的答案：https://dev59.com/UHA65IYBdhLWcg3wvhTi - Ridcully

Answer 1

你可以使用能够解码gif图像的Android Movie类。

Movie.decodeStream(InputStream is);

- sokie

Answer 2

使用WebView而不是ImageView，并在WebView中使用loadUrl。

- Parag Chauhan

Answer 3

使用 Glide 图片加载库，它内置 GIF 支持，语法与加载 JPEG 文件相同：

Glide.with(this).load("http://.../anim.gif").into(imageView);

查看维基百科了解更多信息，并运行Gihpy示例以获得惊喜 :)

- TWiStErRob

Answer 4

你需要使用GIF解码器类，并将其设置在Inflate视图中，这样你就可以在单个活动或屏幕中设置两个视图。

Answer 5

//-----------------GIF Image view ------------

holder.imgAdd.getSettings().setJavaScriptEnabled(true);

holder.imgAdd.setWebChromeClient(new WebChromeClient() {
    public void onProgressChanged(WebView view, int progress)
    {
        activity.setTitle("Loading...");
        activity.setProgress(progress * 100);

        if(progress == 100)
            activity.setTitle(R.string.app_name);
    }
});

holder.imgAdd.setWebViewClient(new WebViewClient() {
    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
    {
        // Handle the error
    }
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url)
    {
        view.loadUrl(url);
        return true;
    }
});

            holder.imgAdd.loadUrl(imgUrl);

你最好将显示动画 Gif 图像的相关代码发布到 ListView 中。而不是一长串的代码。 - Praveenkumar
