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 th

Answer 1

use this:

ImageView.setAdjustViewBounds(true);

Answer 2

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.

Answer 3

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"/>
