android the image looks too small on screen, how to scale it to fit the screen? wrap_content does not seem to work

Question

<RelativeLayout
    android:id="@+id/layout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
<ImageView
    android:layout_alignParentTop="true"
    android:layout_marginTop="100dip"
    android:id="@+id/imageview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:src="@drawable/splash_screen"/>
<ProgressBar
    android:layout_alignParentBottom="true"
    android:layout_marginBottom="20dip"
    android:id="@+id/progressbar"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"/>
</RelativeLayout>

Use the DynamicImageView class explained here: http://stackoverflow.com/questions/13992535/android-imageview-scale-smaller-image-to-width-with-flexible-height-without-crop — goicox, Nov 20 '14 at 00:06

Add the following attribute to your ImageView to get it to scale as you like (will fill the size of your ImageView):

android:scaleType="fitXY"

I would actually change your width attribute as well. Your final XML could look like this:

<ImageView
    android:layout_alignParentTop="true"
    android:layout_marginTop="100dip"
    android:id="@+id/imageview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:scaleType="fitXY"
    android:src="@drawable/splash_screen"/>

This does not work as expected. The image extends to left edge of the screen as expected, but not to right, above and below. — Michael SM, Jan 29 '13 at 19:42

After testing, the following works:

<ImageView
    android:layout_alignParentTop="true"
    android:layout_marginTop="100dip"
    android:id="@+id/imageview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scaleType="fitXY"
    android:src="@drawable/splash_screen"/>
