[SOLVED] how to set ImageView width using Percent support lib and maintain aspect ratio?

how to set ImageView width using Percent support lib and maintain aspect ratio?

Using the Android Percent Support Library, how can I set the width of an ImageView to a percentage of its containing PercentRelativeLayout, while scaling the height in such a way as to maintain the original aspect ratio?

Solution

I got this to work with version 23.0.0 support lib:

<?xml version="1.0" encoding="utf-8"?>
<android.support.percent.PercentRelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:src="@drawable/logo"
        app:layout_widthPercent="50%"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true" />

</android.support.percent.PercentRelativeLayout>
