now i would like to knew how to get display images from galelry inside recyclerview so i can rotate them and upload the rotated images for firebase.
You should consider following steps:
Fire an intent to select images from gallery.
You can access the images by overloading the onActivityResult() function.
Now, you have to save those images using the URIs provided for the images.
Use those images on your recycler view.
Upload them to firebase when the rotation is done.

I have a list of photos that I want to display so I am using a RecyclerView and a RecyclerView.Adapter. So when I bind the view in onBindViewHolder(), I do something like this:
// photo is a Object that contains a url
// photoViewHolder.photo is the imageview
Glide.with(photoViewHolder.photo.getContext()) //use the imageview context
.load(photo.getPhotoScaledURL())//load the photo using an url
.into(photoViewHolder.photo); //into the imageview
But here I am always relying on the URL. Would I be able to somehow always have this image cached? Or is there a better way to do this?
To show some of the images offline first download your image and store the path in DB.Now whenever you offline show the downloaded image.And when online just check the whether image is already downloaded or not, If downloaded then show downloaded image else use glide.
I am new to android, please help me to resolve this. I need to retrieve all images from gallery and show that like an animation using timer or thread. I Used below code get images from gallery how can I store the images in an array?My idea is to make animation using timer by picking images from an array and put in a single Imageview. but I could not store the images retrieved from gallery to an array. I could display it in gridview by using Imageadapter. In short I need to get n number of images from gallery and place it in an array and make animation using timer and single imageview.
String[] projection = {MediaStore.Images.Thumbnails._ID};
cursor=getContentResolver().query(MediaStore.Images.Thumbnails.INTERNAL_CONTENT_URI,
projection,null,null,MediaStore.Images.Thumbnails.IMAGE_ID);
You need to use AnimationDrawable and it's addFrame method. Here is the document.
You can try below link.
It will show how you can select multiple images from gallery;
Get/pick an image from Android's built-in Gallery app programmatically
how to get all the images from in built gallery to my application...?
I don't know how to get the images what are available on the scree. I'm using imageview for the purpose of display the images on the screen.
Images will be changed randomly because i stored the images into array and images are in drawable. I want to know which image is displays on the screen at runtime.
thank u
When you change the image in the ImageView, hold onto the array index that you used in another variable.
I have a gallery that I use to display some ImageViews. I'd like to know which image in the gallery is currently highlighted/focused.
So far, setOnItemClickListener only fires if I actually click on the images. If I scroll through the images, a new image takes focus. I want to know which image that is.
How can I do this?
Get the images number in the list
Get the image (view) it self
I have an app that have more than one gallery. It is a travel app and it have a separate gallery for each trip. When I'm taking pictures with the camera I'm saving them in the default MediaStore of the system.
To view an Image I'm using new Intent(Intent.ACTION_VIEW) and it launches the default image viewer. When scrolling with the left and right arrows it displays all the pictures in the folder where the pictures from the camera are saved.
Is there any way to put an extra in the intent when calling VIEW action which images to scroll trough? I have the IDs of the images for a certain trip in a database.
Or putting them in a separate folder is the only solution?
You could also consider building your own preview activity using a GridView. Of course this is more work to do, but also offers more flexibility:
You can create "virtual" folders
You can display images from local store or from the net (if you want to offer synchronization with web albums for example)
You can highlight certain images (favorite, shared)
