Unwanted padding around an ImageView

Question

I need to include a header graphic in all of my activities/views. The file with the header is called header.xml:

Answer 1

You need to provide shape around imageview to give a better look.

Here what i have used:

<shape xmlns:android="http://schemas.android.com/apk/res/android">
<!--<gradient android:startColor="#FFFFFF" android:endColor="#969696"

    android:angle="270">
-->
<gradient android:startColor="#FFFFFF" android:endColor="#FFFFFF"

    android:angle="270">
</gradient>
    <stroke android:width="2dp" android:color="@color/graycolor" />
<corners android:radius="2dp" />
<padding android:left="5dp" android:top="5dp" android:right="5dp"
    android:bottom="5dp" />

Answer 2

use this android:scaleType="fitXY" in imageview xml

Answer 3

those extra padding is autogenerated since the android would try to get the original aspect ratio. please try below

scaletype = "fitCenter"
android:adjustViewBounds="true"
android:layout_height="wrap_content"

Answer 4

android:layout_height="wrap_content"

You need to change it to "fill_parent"

You also might need to scale your image so it will be the right ratio to fill the framelayout it is in.

I don't understand why you need the frame layout there at all. Without it, your image would just fill the screen anyways.

EDIT: yes, sorry, the xml is the height for the imageview.

Answer 5

android:scaleType="fitXY"

It works for me.

Answer 6

finally!

<ImageView
  (...)
  android:adjustViewBounds="true" />

the adjustViewbounds attribute did the trick:

Set this to true if you want the ImageView to adjust its bounds to preserve the aspect ratio of its drawable.

i stumbled upon it here. thanks for your help!
