回答1:

You can use Android Movie class that is able to decode gifs.

Movie.decodeStream(InputStream is);


回答2:

Use WebView rather then ImageView and loadUrl in WebView.



回答3:

you have to use gif decorder class for that and set it in inflact view so you can set two view in single activity or screen.



回答4:

Use the Glide image loading library, it has built-in support for GIFs and the syntax is the same loading a JPEG file:

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

See the wiki for more and run the Gihpy sample to be amazed :)

//-----------------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);
