Android ImageView scale smaller image to width with flexible height without cropping or distortion

I have solved this by creating a java-class that you include in your layout-file:

public class DynamicImageView extends ImageView {    public DynamicImageView(final Context context, final AttributeSet attrs) {        super(context, attrs);    }    @Override    protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec) {        final Drawable d = this.getDrawable();        if (d != null) {            // ceil not round - avoid thin vertical gaps along the left/right edges        final int width = MeasureSpec.getSize(widthMeasureSpec);        final int height = (int) Math.ceil(width * (float) d.getIntrinsicHeight() / d.getIntrinsicWidth());            this.setMeasuredDimension(width, height);        } else {            super.onMeasure(widthMeasureSpec, heightMeasureSpec);        }    }}

Now, you use this by added your class to your layout-file:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent" >    <my.package.name.DynamicImageView        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:scaleType="centerCrop"        android:src="@drawable/about_image" /></RelativeLayout>

I had the same problem, as yours. After 30 minutes of trying diffirent variations I solved the problem in this way. It gives you the flexible height, and width adjusted to the parent width

<ImageView            android:id="@+id/imageview_company_logo"            android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:adjustViewBounds="true"            android:scaleType="fitCenter"            android:src="@drawable/appicon" />

There is no viable solution within the XML layout standard.

The only reliable way to react to a dynamic image size is to use LayoutParams in code.

Disappointing.
