I have an app where the user needs to be able to choose multiple pictures to send them somewhere. However, they can only send five images at a time. I need to be able to limit the number of images that they can pick from the gallery through the Image Picker.
To put it in a single sentence: I want to limit the number of images/photos that the user can select in the default image selector from the gallery.
Here is the code that I am using for my image picker:
Intent chooseIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
chooseIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
startActivityForResult(chooseIntent, 2);
It already keeps track of how many images are selected at the top by default:
Is there a way to set a maximum limit? Like to have a user only be able to select up to 5 images.

On that particular device, perhaps. Please understand that there are thousands of Android device models, and manufacturers set up their own UI to replace that of stock apps. Do not assume that all devices will show a count in the action bar.

Not via ACTION_PICK
. ACTION_PICK
is not documented to support EXTRA_ALLOW_MULTIPLE
at all, and so there may be devices that do not allow for multiple selection for that Intent
. Even on the Intent
actions for which EXTRA_ALLOW_MULTIPLE
is part of the protocol (e.g., ACTION_GET_CONTENT
), there are no extras for controlling the maximum count.
You are welcome to create your own image-selection UI, based on the results of querying MediaStore
, and establish your own limits. There are also several image picker libraries, and one of those may already offer this feature.
