             "",MediaStore.Images.Thumbnails.MICRO_KIND);

Answer 1

You have two way :

A: Use simple method to set adapter

1. Please set bitmap in image using method setImageBitmap().
2. If you want set bitmap in universal image downloader.

3. Create a method in universal class

   public void setImageThumbnail(String videoPath, ImageView imgView) {
   
      Bitmap b=ThumbnailUtils.createVideoThumbnail(videoPath,MediaStore.Images.Thumbnails.MICRO_KIND);
      imgView.setImageBitmap(b);
   
   }
   

4. use this method where you want.

B :You can also use Lru-cache for adapter.

1. Use worker thread to load bitmap.
2. Create lru cache hashmap to store bitmap.
3. For example please use below code:
