A small simple-to-use ImageView subclass that supports gravity for image placement as well as a mix of easy-to-understand scaling types. Great for hero images or times when you need an image to scale-n-crop as well as be anchored somewhere besides merely the center.
Using the view in xml is super easy. Just point at the desired src like you would with a standard ImageView and specify the imageGravity like you with gravity on any other view. Additionally, imageScaleMode will let you tweak how the image is 1:1 scaled into the view.
<com.chrisrenke.giv.GravityImageView
android:id="@+id/hero_image"
android:layout_width="match_parent"
android:layout_height="140dp"
android:src="@drawable/dinosaur_2000"
app:imageGravity="center_horizontal|bottom"
app:imageScaleMode="crop"
/>The imageGravity or imageScaleMode can also be changed programmatically.
gravityImageView.setImageGravity(RIGHT|CENTER_VERTICAL);
…
gravityImageView.setImageScaleMode(INSIDE);Just add this line to your build.gradle:
