ProportionalImageView

ProportionalImageView is a simple library for your Android project that allows you to set a ratio on Image View component.

Usage

Add a dependency to your app-level build.gradle:

dependencies {
    compile 'com.github.giuseppegiacoppo:proportional-imageview:1.0.2'
}

Add the me.giacoppo.proportionalimageview.ProportionalImageView to your layout XML file.

<LinearLayout 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="wrap_content"
    android:orientation="vertical">

    <me.giacoppo.proportionalimageview.ProportionalImageView
        android:id="@+id/myProportional
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:widthUnits="16"
        app:heightUnits="9" />
</LinearLayout>

That's all. You can set width and height units using app:widthUnits and app:heightUnits xml attributes, or programmatically:

ProportionalImageView proportionalView = (ProportionalImageView) findViewById(R.id.myProportional);
proportionalView.setWidthUnits(16);
proportionalView.setHeightUnits(9);

You can set the ratio too:

proportionalView.setRatio(0.5625);

Remember, ratio is intended as heightUnits/widthUnits.
