picasso

问题 I have been searching SO threads for answers but couldn't figure out my issue from previous discussion. I have a listview which loads about 50 images (it used to be about 100 but this was barely loading any images at all). After grabbing my JSON content (including image URL) from an api endpoint, through an adapter, my code puts it inside the listview. Currently, with 50 images, picasso will load one image at a time as I scroll down on the feed. I feel as if keeping the scroll fixed on one

问题 I have a URL link to get images, and that image may change everyday however the link doesn't change. My questions are In this case, how Picasso know the image has changed and grab a new image? Does Picasso fires a url call to my server every-time the image is being used and then determine if the image is different or not? 回答1: Picasso uses HTTP headers for caching, so it basically follows the HTTP Caching specification.

问题 I use Picasso to retrieve the Bitmap image to use as a marker icon and it apply successfully. But I need to dynamically increase the size of the custom marker for all devices. Because with my code below, it's working fine in some devices but in some others devices, the marker is very big.
