Android GIF transparent background disappears

Question

I'm new to Android Java programming. For a project I need transparent images, which change dynamically. I have created a layout with an ImageView. And in it a small GIF USA flag GIF with a transparent background.

In code I connect the variable to the imageview and assign the same image to the variable from the ImageResources

ImageView image = (ImageView)convertView.findViewById(R.id.listview_image);
image.setImageResource(R.drawable.vlag);

This goes pretty well however the image is displayed with a white background. The transparency is lost. This is shown in the image below by the white background.

GIFs can be problematic. Let me suggest you converting it to PNG. — Phantômaxx, Sep 15 '15 at 12:23

GIF over ImageView are always an issue. Use GIFImageView

And you must use it this way:

 gifImageView = (GifImageView) findViewById(R.id.gifImageView);
 gifImageView.setBytes(bytes);
 gifImageView.startAnimation();

Even it has an option to download the gif from the web.

Same here, it provides a solution for Animation, not for Transparency. – Vincent Sep 16 '15 at 06:29
Other solution would be to have each frame of the GIF (png files) and have an xml animation. – Mariano Zorrilla Sep 16 '15 at 11:56

Then, use PNG files if you don't want animation... if you want transparency AND animations, go for xml animations frame by frame. Using GIF for just transparency is pointless. – Mariano Zorrilla Sep 17 '15 at 12:15
The images are in GIF. I have already tried a couple a GIF2PNG routines without succes. They all mess up the transparency. :-( – Vincent Sep 18 '15 at 05:30
Exists some software to extract each frame and those frames keep the transparency (even if is just 1 frame) – Mariano Zorrilla Sep 18 '15 at 11:51
