With ImageView
, I can use the following code to download image with callback
Picasso.with(activity).load(url).into(imageView, new Callback()
{
@Override
public void onSuccess()
{
// do something
}
@Override
public void onError() { }
);
Or simply get the Bitmap from this Picasso.with(activity).load(url).get();
. Is there anyway to add callback for just download the image? If possible please provide sample code, Cheers!
You can create a Target
and then modify the Bitmap
inside the Targets callback method onBitmapLoaded(...)
. Here is how:
// make sure to set Target as strong reference
private Target loadtarget;
public void loadBitmap(String url) {
if (loadtarget == null) loadtarget = new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
// do something with the Bitmap
handleLoadedBitmap(bitmap);
}
@Override
public void onBitmapFailed() {
}
};
Picasso.with(this).load(url).into(loadtarget);
}
public void handleLoadedBitmap(Bitmap b) {
// do something here
}
