ImageView not covering complete width of the parent CardView

Question

I have a parent LinearLayout inside which I have 2 CardViews. I have an ImageView inside each CardView. When I load image in any of ImageView its not taking the complete width of the CardView. There is a slight white gap between the ImageView and CardView. How can I overlap the ImageView completely over the CardView? Here is my layout.

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:background="#F5F5F5"
        android:gravity="center">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <android.support.v7.widget.CardView
                android:id="@+id/adhaarCardFrontUpload"
                android:layout_width="0dp"
                android:layout_height="@dimen/adhaar_height"
                android:layout_marginBottom="5dp"
                android:layout_marginEnd="5dp"
                android:layout_marginStart="10dp"
                android:layout_marginTop="5dp"

Change adjustViewBounds to false.

<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="false"
android:scaleType="fitXY"
android:src="@drawable/ic_add" />

If you want the ImageView to adjust its bounds to preserve the aspect ratio of its drawable then set this to true.

Actually I am talking about the `ImageView` with `id="adhaarCardBackImage"`. I have it as match_parent but still it doesn't take the complete width of the parent `CardView` – sagar suri Apr 01 '18 at 16:34
Did you try toggling adjustviewbounds? – Ajay J G Apr 01 '18 at 16:36

You should use MATCH_PARENT.

Special value for the height or width requested by a View. MATCH_PARENT means that the view wants to be as big as its parent, minus the parent's padding, if any.

Try this way,

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:adjustViewBounds="true"
    android:scaleType="fitXY"
    android:src="@drawable/ic_add" 
  />

Try with

 android:adjustViewBounds="true"
 android:scaleType="fitCenter"

Add `fitXY` there instead of `android:scaleType="centerCrop"` – IntelliJ Amiya Apr 01 '18 at 16:24
I tried that as well. It gave me more bad results. `centerCrop` gave good results but there is slight gap at the sides of the CardView. `fitXY` didnt even come close to the width of the `CardView` – sagar suri Apr 01 '18 at 16:28

Nope. Still trying to figure out what is the mistake. – sagar suri Apr 03 '18 at 12:47
