I am implementing user wall like facebook but i want to display image
as with original size. And I am using view pager to display images.
So how to display images according to screen size?
Thanks in advance..
You need to use one of the scale types provided with ImageView class. How do you handle if the image is way larger than the screen, say taken from a DSLR at 3000x3000 resolution? What happens if the image is too small?
Have a look at the documentation for ImageView.ScaleType:
I need to crop and center an image to make a thumbnail for a list, but I want the size of the thumbnail to be proportional to the screen size, so that when the list is shown on a tablet or on a phone the image can be perceptible.
Any idea how can I do this?
You can use an ImageView to display the thumbnail.
Set the size of the ImageView in the layout XML, where you can set a different size for each screen size, by following this guide: http://developer.android.com/training/basics/supporting-devices/screens.html
Make sure the scale type of the ImageView is set according to your need by setting the correct android:scaleType property to your ImageView. The available scale types can be found here: http://developer.android.com/reference/android/widget/ImageView.ScaleType.html
That should do the trick.
I have an imageview that loads and image in the xml.
I was wonder, how can I programmatically increase the image size ( or reduce it) by scale of 2? (so double it or make it half size)
Please help
Thanks
I have a Gallery. I have used the android:unselectedAlpha parameter so that the center image in the Gallery is more bright. However, I would like to have this center image size to be bigger than other images. Is there a way to do this ?
You could add and onClickListener to each image. When the image is clicked you could change the layout so that the image is then bigger.
I want to create a list with some text and a photo miniature in each row.
So I created a row layout with a TextView and a ImageView, my question is how do I make the ImageView just a little square and then make an image adapt to the size of the ImageView?
<ImageView .... android:scaleType="centerInside" />
Set full screen image as an image resource of this image view. It will be downscaled automatically.
Additionally you can limit width and height setting android:maxWidth and android:maxHeight attributes to prevent minature to be too large.
my recommendation is you do not scale the image to fit the view as this is an expensive operation and will slow down your app it is preferable to prescale the item to the size you want.
Take a look at this Strange out of memory issue while loading an image to a Bitmap object. It's a correct way to get miniature with minimum memory consumption.
