I have a files's list in my Android app and I want put them a preview image, an icon (thumbnail).
I have got this purpose for image and video files, but not for text files.
In this last case, I know there is a Google Docs function that it creates an image from a text file that it can be used like thumbnail:
http://docs.google.com/viewer?url=MY_LINK&a=bi&pagenumber=1&w=300
Here, you can put the text file url, the number page and the width for thumbnail.
This method works well, but I don't know like obtaining the image created with this url, for saving in a Bitmap and put it in the icon ImageView.
Thanks for your attention.

I am using glide to load image from Sd Card which is downloaded from server and then write into Sdcard.
Some time Image appear half black and some time image appear fully black. Like given image.
Unable to get the reason.
Images are loading in recycle list items.
One thing I want to mention that image after downloading, appear correctly in the sdcard, problem is while reading from sdcard to image view.
I have used both Picasso and Glide in order to load images asyncronously in grids with images coming from the phone's external memory and in order to download photos from the Internet.
But now for my Android game in the first screen I need to display an image below a title (the image takes up all available height). Then the user taps on a specific part of the image and the game starts.
The image content is a drawable resource.
So, for this specific use (a TextView and an ImageView below it which takes up all the remaining space), what should I do:
-Specify the image as ImageView's src property.
-Use an image loading library, such as Picasso or Glide
What do you suggest and why?
Thank you.
EDIT: The image would be static, a static drawable resource.
This is a different situation. I want to load a image file which has stored with different extension like 'photo.xyz' instead of 'photo.jpg or photo.png' using Picasso. to avoid image from gallery i am storing image like this. Please help me is there any option to show like this.
Neither Picasso nor Android (which does the actual image decoding) cares what the file name is. It can be anything. The type of the image is always determined from the first few bytes of the actual image data.
As a small workaround you can programmatically put .nomedia file into your app folder to prevent images to be cached by mediaserver and displayed in a Gallery app.
I am working on a simple app in SDK Android and i have the follwing problem:
I have already converted my png. images in SVG and now i want to make them interract.
The problem is that the whole image is made up from other images or text fields etc.
So, as i have saved it in .svg format i want to find a way to handle for example the button, when clicked, that exists at the center of my photo, the scroll bar at the bottom, when clicked etc in order to go to another svg image. I don't know how i could handle them seperately, as i save the whole image as svg that contains all the above parts..
Thanks in advance
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).
