Dynamic image height in recycler view

I want to load images with dynamic height using Glide. I have an ImageView whose height is wrap_content and width is match_parent. When the recycler view loads the first time. The first image has a larger height than the rest of the images. My larger height image loads fine without any pixelation when I scroll down the view gets recycled and when I scroll back to top to first larger image it gets pixelated I think when the view gets recycled glide is using smaller recycler imageview height for downsampling the larger height image due to which its getting pixelated. I don't want to use setRecyclable (false) on recyclerview. Here's the implementation
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="#+id/drc_imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:src="#color/OFF_WHITE" />
</LinearLayout>
For loading the image
GlideApp
.with(context)
.asBitmap()
.fitCenter()
.load(absoluteHomeList.get(position - 1).getDynamic_card_url())
.into(holder.dynamicImageView);
Here are the images for reference

Before loading image using glide use
holder.dynamicImageView.layout(0,0,0,0);

Fit imageView to image size after resizing it

I am implementing something called InApp messages, now I am trying to fit ImageView to image size after resizing.
This is my imageView:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginStart="15dp"
android:layout_marginTop="40dp"
android:padding="6dp">
--other components--
<ImageView
android:id="#+id/middleLayoutImage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/border"
android:padding="5dp"
app:layout_constraintBottom_toTopOf="#+id/middleLayoutText"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#+id/topWrapper"
app:layout_constraintVertical_chainStyle="packed" />
--other components--
</android.support.constraint.ConstraintLayout>
To download img and put into this view I am using Picasso:
Picasso.with(getApplicationContext())
.load(inputurl)
.into(imageView);
Now my activity looks like this:
Before fitting
Now I want to resize it with aspect ratio to width of the parent Layout. I've tried a lot od combinations with no success:
android:scaleType="fitXY" - stretched img
picasso fit().centerCrop() - centerCrop
picasso fit().centerInside() - centerInside
and more combination with android:adjustViewBounds scaleTypes etc.
I want to achieve something like this: Resized correctly - in this case, I've used picasso: .resize(2000,500).centerInside() - but it will work only in this case.. How to do it automatically ?
Thanks in advance for help:)
edit:
ImageView imageView = (ImageView) findViewById(R.id.middleLayoutImage);
String inputurl = "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSQtqf1EUqH4eQNNqYFbSawpiR5bypfOhvlatgS0mC3Ve1nk2adbw"; //http://www.gatesms.eu/img/android.png";
Picasso.with(getApplicationContext())
.load(inputurl)
.resize(2000,500)
.centerInside()
.into(imageView);

For Picasso to fit your Image correctly you should know the size of your Image. But for this case You do not know the size of the Image then for good UI design you should have a placeholder (An image to show while Picasso is loading another) keep that image in your drawable folder lets call it placeholder and set it as a src or alternatively using Picasso itself like this:
Picasso.with(getActivity())
.load(imageUrl)
.placeholder(R.drawable.placeholder)
.error(R.drawable.error)
.resize(screenWidth, imageHeight)
.fit()
.centerCrop()
.into(imageView);
Now what?
Now because you have another Image in the imageView Picasso now knows the height and width so that It can fit your Image well. But if you do not provide any image then the results are very small images or improperly stretched ones. I have also added an optional error image that will be displaced if Picasso fails to make the request like my be No network Connection you can omit it if you want.
Do not forget the android:adjustViewBounds in XML too.

how to fix stretching image in image view in android when i use fitxy Scale type in android

<ImageView
android:id="#+id/bigimages"
android:layout_width="match_parent"
android:layout_height="150dp"
android:layout_below="#+id/productTitle"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="40dp"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:src="#drawable/bath_and_body_1" />
Glide.with(this)
.load("https://images-eu.ssl-images-amazon.com/images/I/41ZNY84Q-7L.jpg")
.placeholder(R.drawable.cancel_icon)
.into(bigimages);
https://images-eu.ssl-images-amazon.com/images/I/41ZNY84Q-7L.jpg
this is my code and image URl i have to display full image without streching but i am not able to display its stretched please suggest me how to fix it . below is current image which is stretched
enter image description here
how to fix there is stretching in text yellow....

YOu can try :
android:scaleType="fitXY"
android:adjustViewBounds="true"

Change to
android:scaleType="centerCrop"
or
Glide.with(this)
.load("https://images-eu.ssl-images-amazon.com/images/I/41ZNY84Q-7L.jpg")
.placeholder(R.drawable.cancel_icon)
.centerCrop()
.into(bigimages);

Of the various scaleType options, fitXY is specifically made to stretch the image. It will make sure that the entire image is stretched/shrunk to fit in exactly the space provided.
You probably want centerInside; this will make sure that the entire image fits within the view, and will not distort the aspect ratio. If your view is square and the image is rectangular, centerInside will scale the image down so that it fits inside the view, meaning either the top+bottom or left+right will be empty.

Alter your Glide implementation with:
Glide.with(this)
.load("https://images-eu.ssl-images-amazon.com/images/I/41ZNY84Q-7L.jpg")
.override(width, height) //set width & height as you want
.palceholder(R.drawable.cancel_icon)
.into(bigimages);

Resizing image with picasso

Hey everyone I have been running into an issue with Picasso. I am trying to load an image from sound cloud but it keeps appearing stretched or very small. Here is my XML
<ImageView
android:id="#+id/album_cover_art"
android:layout_width="300dp"
android:layout_height="200dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="#dimen/fragment_content_item_top_margin"
android:scaleType="centerInside"
android:contentDescription="#string/content_description_image_placeholder"
android:src="#drawable/placeholder" />
I tried to use picasso's resize and center inside but the image appears small.
Picasso.with(getContext()).load(mSelectedTrack.getArtworkURL()).resize(800,300).centerInside().into(mAlbumCoverArt);
Using picasso's resize and center crop maintains the image view size but leads to the image appearing stretched.
Picasso.with(getContext()).load(mSelectedTrack.getArtworkURL()).resize(800,300).centerCrop().into(mAlbumCoverArt);
Any ideas on a way to do this that is easier than writing a function to resize it myself ?

I avoided image stretching using :
.resize(800,0)
Passing 0 as second parameter it preserved the image proportions.
Hope it helps

try this:
for your imageview:
<ImageView
android:id="#id/img"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true" //add this
android:scaleType="fitCenter" />
And in picasso use .fit().centerCrop()
Picasso.with(getContext()).load(mSelectedTrack.getArtworkURL()).resize(800,300).fit().centerCrop().into(mAlbumCoverArt);

Try setting height or width to fixed and other to wrap content and load Picasso with .fitXY and don't use . resize.

Give a try to Glide.
https://github.com/bumptech/glide
Glide.with(this)
.load(imageUrl)
.centerCrop()
.override(300, 300)
.into(imageView);

Android crop imageview

There is my ImageView
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="150dp" />
I load image to this ImageView using Picasso library.
Picasso.with(getActivity()).load(url)
.config(Bitmap.Config.RGB_565)
.into(imageView);
There is problem that there is padding inside ImageView and loaded image.
There is image to show padding:
I use .fit() method to avoid this gap, but image stretches and quality losts.
(You can see that this dark-blue circles is ovals now)
The question is:
What should I do to avoid loosing quality of image and resize it directly to ImageView. I can't add .centerCrop() because left side of image is logical safe-zone. Also I can't change layout_height="150dp" because it will break all my layout.
Anyway thank you!

Look at your ImageView:
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="150dp" />
You are forcing the image to stretch to the width of its parent view (the screen maybe?). Try using wrap_content for the width and keeping the height the same. This may cause the image to shrink, but its up to your desired UX.
#stefs found that adding this:
...android:adjustViewBounds="true" />
would help. Check out the post here.
If you want static image sizes, you may have to deal with the padding.
