android: stretch image in imageview to fit screen

Question

I have an imageview that has its height and width set to fill_parent with a linearlayout that has the same values set. So I suppose this should set my images to fit the screen. But it only fits like 80% (margin top and bottom in landscape mode).

I've tried the following code without success:

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();
int height = display.getHeight();

imgView.setMinimumWidth(width);
imgView.setMinimumHeight(height);

imgView.setMaxWidth(width);
imgView.setMaxHeight(height);

Any other ideas?

Although it's a slightly different problem, [this answer](http://stackoverflow.com/questions/2991110/android-how-to-stretch-an-image-to-the-screen-width-while-maintaining-aspect-rat/2999707#2999707) should help you. — fredley, Jan 12 '11 at 11:51

to change pro-grammatically use :

imgview.setScaleType(ScaleType.FIT_XY);

OR

to change from xml use:

 android:scaleType="fitXY"

I know this is what you wanted, but for images where you care about aspect ratio, this will stretch it out. – Artem Russakovskii Nov 15 '11 at 01:39
Works wonders for ImageView inside a ScrollView. Even the aspect is kept correct. – JNissi Oct 17 '12 at 04:52

The same can be defined in the layout xml, android:scaleType="fitXY" – Sathesh Oct 17 '14 at 10:46

To make the image fill all the area and keep a good aspect ratio use `v.setAdjustViewBounds(true); v.setScaleType(ImageView.ScaleType.CENTER_CROP);` – Marco Florian Jun 20 '16 at 09:23

@MarcoFlorian Why not just use FIT_CENTER? Is there any reason? – Jenix Aug 01 '17 at 05:46
@Jenix `FIT_CENTER` will fit it horizontally or vertically leaving the rest of the area empty. https://4.bp.blogspot.com/-8SBHoA5e0M4/VeFSX8HX7qI/AAAAAAAAbI0/z2STMO_cAeY/s1600/AndroidImageViewScaleType_Fit_Center.png – Marco Florian Aug 02 '17 at 07:13
@MarcoFlorian Yeah, I know what FIT_CENTER and CENTER_CROP are, and that's why I'm using FIT_CENTER most of the time over CENTER_CROP in my apps so far. But I didn't know about the 'v.setAdjustViewBounds(true)' thing so tried with CENTER_CROP as you did, and surprisingly, it worked just like FIT_CENTER. I'm happy to know new thing but asked you the question because if there's any reason writing two lines over one line.. – Jenix Aug 02 '17 at 09:03
@Jenix, didn't notice this comment till now. `v.setAdjustViewBounds(true)` will make it fit the area boundaries if the image is bigger or smaller. `FIT_CENTER` or `CENTER_CROP` are applied then. Do your tests with small and big images, you will notice the differences this way. – Marco Florian Nov 29 '17 at 17:52
@Marco Florian Thanks for the reply. When I asked the question, I was working with some projects and tested on one of it. I don't know which one it was, and don't remember I actually tested with both bigger and smaller images even though I think I would, and did. So I gave it another try with an empty project, but this confuses me more.. Calling setAdjustViewBounds() with both true and false doesn't affect at all. – Jenix Nov 30 '17 at 10:39
Whether it's true or not, setting to ImageView.ScaleType.CENTER_CROP is always CENTER_CROP, and setting to ImageView.ScaleType.FIT_CENTER is always FIT_CENTER. At that time, I asked you purely out of curiosity but I think I need to take some time trying many different cases. Thanks. – Jenix Nov 30 '17 at 10:39

Give in the xml file of your layout android:scaleType="fitXY"
P.S : this applies to when the image is set with android:src="..." rather than android:background="..." as backgrounds are set by default to stretch and fit to the View.

This doesnt take care of aspect ratio if you hardcode the images' width and want the height to scale – Akshat Agarwal Dec 05 '13 at 21:15
How can I get this to fit the whole screen then? I want it to still be proportional – Ruchir Baronia Nov 07 '15 at 21:27
+1 for telling it applies to android:src="..." rather than android:background="..." this is very important – DragonFire May 11 '19 at 14:56

This in combination with `android:scaleType="fitXY"` is what worked. Thanks – smac89 Jul 26 '15 at 19:20
@smac89 What is the difference between those combination and just using FIT_CENTER? Should not use FIT_CENTER? – Jenix Aug 01 '17 at 05:48
@Jenix, mind you it's been a while since I last touched Android, but I believe the reason for doing `fitXY` is so that the image is stretched proportionally to fit the frame/view it was set in. Using `FIT_CENTER` sounds like it will just place the image in the center of the view but does not fill the view. I may be wrong, but you can experiment with either to find out what works – smac89 Aug 01 '17 at 15:19
@smac89 Before asking I already tested both of them and it worked just the same. I was curious about the reason but now think you didn't know FIT_CENTER just like the fact I didn't know about the combination you let me know. :) – Jenix Aug 02 '17 at 09:11

if you use android:scaleType="fitXY" then you must specify

android:layout_width="75dp" and android:layout_height="75dp"

if use wrap_content it will not stretch to what you need

<ImageView
android:layout_width="75dp"
android:layout_height="75dp"
android:id="@+id/listItemNoteImage"
android:src="@drawable/MyImage"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_marginStart="12dp"
android:scaleType="fitXY"/>

The accepted answer is perfect, however if you want to do it from xml, you can use android:scaleType="fitXY"

just change your ImageView height and width to wrap_content and use

exampleImage.setScaleType(ImageView.ScaleType.FIT_XY);

in your code.

Maybe this is irrelevant. This how I do it on android studio.

Put this in the xml:

android:adjustViewBounds="true"

android:scaleType="centerCrop"

adjustViewBounds = will fit the image according to the ratio

scaleType = crop out all the white empty spaces

Then, set the

layout_width = match_parent 
layout_height = warp_content

will become like this

Trying using :

imageview.setFitToScreen(true);
imageview.setScaleType(ScaleType.FIT_CENTER);

This will fit your imageview to the screen with the correct ratio.
