I wont to make simple image to Animated image like GIF.I can select the image for gallery and store in image file.But, How i can modify image file to animated image or GIF File .

回答1:

you have to select images you want to make GIF, then use bitmaps and run code in background Thread/Asynchtask:

Here i used Drawable, in your case convert images into bitmap and use it.

            Bitmap one=BitmapFactory.decodeResource(getResources(),R.drawable.neon0);
            Bitmap two=BitmapFactory.decodeResource(getResources(),R.drawable.neon1);
            Bitmap three=BitmapFactory.decodeResource(getResources(),R.drawable.neon2);


            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            AnimatedGifEncoder encoder = new AnimatedGifEncoder();
            encoder.start(bos);


            encoder.addFrame(one);
            encoder.addFrame(two);
            encoder.addFrame(three);
            encoder.finish();

            FileOutputStream outStream;
            try{
                outStream = new FileOutputStream(Environment.getExternalStorageDirectory().getPath() + 
                "/IMAGES_GIF/" + "animated.gif");
                outStream.write(bos.toByteArray());
                outStream.close();
            }catch(Exception e){
                e.printStackTrace();
            }

回答2:

This question needs a lot more information. Is the file already a GIF and it is not animating or are you trying to convert an image to a GIF? The latter is not possible, a GIF is a series of images.

You must create the GIF elsewhere and it is easiest to use a library like Glide (https://github.com/bumptech/glide) or Picasso (http://square.github.io/picasso/) to load the GIF.
