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;

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've been following some tutorials and i can achieve to get the thumbnails, but the problem is the following :
when i send the bitmap to the other activity (display activity) i get the thumbnail MINI_KIND Size, and the startup of my application takes much time than usual to launch,
What i want is :
a fast way to load all SdCard images, to display them in Grid View and when i click one of them to be able to get its file path to display in the other activity
Can someone help me please ?
I will show you my way to do this.
Using cursor to load all image path from sdcard.
Using Universal Image Loader to display it.
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 am using the following code to pick a folder from the SDCard.
Environment.getExternalStorageDirectory();
After selecting the folder, I return the path of the folder and display it in a text view currently.
What I want to do is, I want to display all images in the selected folder in the form of a slide show. How do I go about in doing this?
1. convert images in the Bitmap.
Bitmap bm = BitmapFactory.decodeFile(String pathName);
Decode a file path into a bitmap.BitmapFactory
2. Using ImageView set that Bitmap in ImageView.
ImageView.setImageBitmap(Bitmap bm);
Sets a Bitmap as the content of this ImageView.
3. For slide show just after some delay (use timer) after change the bitmap of ImageView.
We are appreciate If you are do by yourself. Without finding any code.
EDIT: Here Mihai Fonoage's Blog Displaying Images from SD Card In Android - Part 2 It display images from sdcard in Gridview. You can modified it and display Images one-by-one as a slideshow.
If all you want to do is cycle through the images one by one, there are numerous options. You could for example simply use a Timer (or preferably a ScheduledThreadPoolExecutor if you're writing production code) with a fixed interval or have a Handler repeatedly post itself with a certain delay. With each 'tick' you can then simply set the next image.
If you're after something a little more fancy, it may be worth looking at implementing an ImageSwitcher, which provides the ability to also show thumbs of upcoming/previous images. Code examples are wide spread, e.g. here (scroll down a bit).
I have a GridView displaying thumbnails using ImageViews. I am displaying a default image while the thumbnail images are being downloaded from the background(inspired from native applications) i.e. the getView() of my adapter class returns a default Bitmap first and then runs a background thread and replaces the default with actual later.
GridViews in iPhone application display a spinner (Animated GIF) instead of default image.
How can a similar thing be achieved in Android?
As Raj commented, get DroidFu's WebImageView here.
