Question

Here is a picture that will help you understand my problem:

I want to stretch

Answer 1

If your image "111" has no padding itself then simply use android:background"@drawable/111"

Answer 2

Use below code :-

<ImageButton
        android:id="@+id/secondActivityBbuttonDownRight"
        android:layout_width="0dip"
        android:layout_height="match_parent"
        android:layout_weight="0.5"
        android:scaleType="fitStart"
        android:background="@drawable/111" />

Answer 3

android:scaleType="fitXY" tested and works correctly.

Answer 4

You can also use

android:scaleType="centerCrop"
android:padding="0dp"

Answer 5

Just set this two attributes on the ImageButton:

android:background="?attr/selectableItemBackgroundBorderless"
android:scaleType="centerCrop"

With those, you will get the provided src to be stretched, and also if you put some specific width and height on that ImageButton you won't get a rectangle around it.

Answer 6

ImageButton is ImageView.
If you want your image to fill button
than set android:scaleType="fitXY", so the image you set in android:src will be stretched to fill whole image button.

ImageButton has a background under your image and padding.
If you do not want background
set android:background="@android:color/transparent".
If you do not want padding
set android:padding="0" or set background without padding.
