[java] Android set bitmap to Imageview

There is a library named Picasso which can efficiently load images from a URL. It can also load an image from a file.

Examples:

  1. Load URL into ImageView without generating a bitmap:

    Picasso.with(context) // Context
           .load("http://abc.imgur.com/gxsg.png") // URL or file
           .into(imageView); // An ImageView object to show the loaded image
    
  2. Load URL into ImageView by generating a bitmap:

    Picasso.with(this)
           .load(artistImageUrl)
           .into(new Target() {
               @Override
               public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
                   /* Save the bitmap or do something with it here */
    
                   // Set it in the ImageView
                   theView.setImageBitmap(bitmap)
               }
    
               @Override
               public void onBitmapFailed(Drawable errorDrawable) {
    
               }
    
               @Override
               public void onPrepareLoad(Drawable placeHolderDrawable) {
    
               }
           });
    

There are many more options available in Picasso. Here is the documentation.
