Stretch image in ImageView

Question

I have an ImageView that has a height and width set to "fill_parent" using a Relative Layout that has the same values. Set scale scaleType = "fitXY"

Here's the XML layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:id="@+id/imageView1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:scaleType="fitXY" android:src="@drawable/background_image" /> </RelativeLayout> 

Sets the width and height, but the image is stretched.

Answer 1

What fitXY should do. You can try centerInside if you do not want to crop the image or centerCrop if you want to fill the entire space (and crop the image).

Here is a good list with examples to better understand scale types:

Answer 2

These two properties solved the problem for me:

 android:scaleType="fitXY" android:adjustViewBounds="true"
