So i want to choose some images from gallery then display these images inside recyclerview , layout of image inside recyclerview would have a rotate button to rotate images before uploading to firebase.
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 want to load image from SQLite DB in my android app and set its values into a image slider (viewpager) similar this tutorial :

please help !
You first need to save your images in database in form of byte[] and then retrieve one by one in your pager adapter then convert byte[] to Bitmap and set in ImageView. But this is not a good practice.
If your images are static then you should store them in drawables as shown in that tutorial and if your images are dynamic and fetched from network you should use Picasso, Glide or any such library to load those images directly from network into your ImageView.
This tutorial might help you in integrating Picasso library.
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 want to display thumbnail image as image icon in ListView.
I am using array list that contains all thumbnail images path, these path will be accessed from the server.
My arraylist as ahown below.
mylist=['a1','a2','/playback/2012/a1.jpg','b1','b2','/playback/2012/000_b1.jpg', .....]
In this nearly 15 paths are there.. Now i want to display these images in listview.
'a1' is videoName 'a2' is categoryName and one more is path.
These path will be accessed from server only.. I think, we can't store it in drawable.
These are always changing.
How to solve it?
