How can I use Picasso to add an icon in Marker?

Question

I would like to use Picasso to extract a bitmap image to use as a marker icon, but I'm not sure how to do this. If I use Picasso to insert an image into an image, I know that I can use:

Picasso.with(MainActivity.this).load(URL).into(photo_imageview); 

Of course, this will not work if you pass it to .icon()

Is there an easy way to achieve this?

Thanks for watching this!

Answer 1

Picasso provides a generic Target interface that you can use to implement your own target image. In particular, you will want to override onBitmapLoaded to fill your token.

Below is a basic implementation.

 public class PicassoMarker implements Target { Marker mMarker; PicassoMarker(Marker marker) { mMarker = marker; } @Override public int hashCode() { return mMarker.hashCode(); } @Override public boolean equals(Object o) { if(o instanceof PicassoMarker) { Marker marker = ((PicassoMarker) o).mMarker; return mMarker.equals(marker); } else { return false; } } @Override public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) { mMarker.setIcon(BitmapDescriptorFactory.fromBitmap(bitmap)); } @Override public void onBitmapFailed(Drawable errorDrawable) { } @Override public void onPrepareLoad(Drawable placeHolderDrawable) { } } 

You would use it like this:

 marker = new PicassoMarker(myMarker); Picasso.with(MainActivity.this).load(URL).into(marker); 

Note Picasso only supports the weekly Target link passed to into . Therefore, a marker link must exist prior to loading the image to avoid garbage collection of callbacks.

Check out this sample Google code code, you can find the InfoWindowAdapter implementation to achieve it: googlemaps / android-samples
