Do you want to change the shape of your ImageView in android ? . If yes then its the right place to look into it. Material Design 1.2.0 introduced ShapeableImageView that draws the image with the provided Shape in your imageview.

By using ShapeableImageView, you can change the shape of your image to circle, diamond, etc. Also, you can set corner radius to your imageview. You can do much more by using this ShapeableImageView with minimal code.

Checkout the official ShapeableImageView Doc

To work with ShapeableImageView in your android project, you need to add dependency material design 1.2.0 or higher.

implementation 'com.google.android.material:material:1.2.0'

Sliders — Material Components also introduced in material design 1.2.0.

Important attributes of ShapeableImageView

app:shapeAppearanceOverlay — This is working as a ThemeOverlay. ShapeAppearanceOverlay apply the defined changes without affecting the active theme.

<style name="ShapeAppearanceOverlay.App.CornerSize50Percent" parent="">

<item name="cornerSize">50%</item>

</style>

The key to the overlay behavior is the empty parent attribute. This is what causes the overlay behavior. Lets create imageview in different shapes.

In the above style, cornerSize only affected by the overlay. remaining properties same as active theme.

cornerFamily — corner family to be used for all four corners

cornerFamilyTopLeft — corner family to be used for the top left corner

cornerFamilyTopRight — corner family to be used for the top right corner

cornerFamilyBottomRight — corner family to be used for the bottom right corner

cornerFamilyBottomLeft — corner family to be used for the bottom left corner

cornerFamily is a enum type and the supported values are rounded, cut.

cornerSize — corner size to be used for all four corners

cornerSizeTopLeft — corner size to be used for the top left corner

cornerSizeTopRight — corner size to be used for the top right corner

cornerSizeBottomRight — corner size to be used for the bottom right corner

cornerSizeBottomLeft — corner size to be used for the bottom left corner

Imageview in circle shape

Circle shape imageview

Using XML

as mentioned above, first we need to set the app:shapeAppearanceOverlay. In the overlay we need to mention the corner radius size to 50% to make the imageview as circle.

<com.google.android.material.imageview.ShapeableImageView

android:layout_width="150dp"

android:layout_height="150dp"

app:layout_constraintTop_toTopOf="parent"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:srcCompat="@mipmap/ic_launcher"

android:layout_margin="10dp"

app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.App.CornerSize50Percent"

/>

In your style.xml add,

<style name="ShapeAppearanceOverlay.App.CornerSize50Percent" parent="">

<item name="cornerSize">50%</item>

</style>

If you want to add stroke to circle imageview, you can add stroke attributes in your ShapeableImageView.

Circle shape imageview with stroke

<com.google.android.material.imageview.ShapeableImageView

android:layout_width="250dp"

android:layout_height="250dp"

android:padding="5dp"

app:strokeWidth="10dp"

app:strokeColor="@android:color/darker_gray" app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.App.CornerSize50Percent"

app:layout_constraintTop_toTopOf="parent"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:srcCompat="@mipmap/ic_launcher"

android:layout_margin="10dp"

/>

Dynamically using Kotlin

val radius = resources.getDimension(R.dimen.corner_radius)

val shapeAppearanceModel = circleShapeImageView.shapeAppearanceModel.toBuilder()

.setAllCornerSizes(radius)

.build()

circleShapeImageView.shapeAppearanceModel = shapeAppearanceModel

set the corner radius in dimens.xml

<dimen name="corner_radius">125dp</dimen>

Corner Radius Imageview

Corner radius imageview

Using XML

we need to set the app:shapeAppearanceOverlay. In the overlay we need to mention the corner radius size to 10% to set the corner radius.

<com.google.android.material.imageview.ShapeableImageView

android:layout_width="150dp"

android:layout_height="150dp"

app:layout_constraintTop_toTopOf="parent"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:srcCompat="@mipmap/ic_launcher"

android:layout_margin="10dp"

app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.App.CornerSize10Percent"

/>

In your style.xml add,

<style name="ShapeAppearanceOverlay.App.CornerSize10Percent" parent="">

<item name="cornerSize">10%</item>

</style>

same way, If you want to add stroke to corner radius imageview, you can add stroke attributes in your ShapeableImageView.

Corner radius imageview with stroke

<com.google.android.material.imageview.ShapeableImageView

android:layout_width="150dp"

android:layout_height="150dp"

app:layout_constraintTop_toTopOf="parent"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:srcCompat="@mipmap/ic_launcher"

android:layout_margin="10dp"

app:strokeWidth="10dp"

android:padding="5dp"

app:strokeColor="@android:color/darker_gray"

app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.App.CornerSize10Percent"

/>

Dynamically using Kotlin

val radius = resources.getDimension(R.dimen.corner_radius)

val shapeAppearanceModel = circleShapeImageView.shapeAppearanceModel.toBuilder()

.setAllCornerSizes(radius)

.build()

circleShapeImageView.shapeAppearanceModel = shapeAppearanceModel

set the corner radius in dimens.xml

<dimen name="corner_radius">12dp</dimen>

Corner cut imageview

Corner cut imageview

Using XML

For the corner cut imageview, we are going to use cornerFamily attribute.

by default, cornerFamily will be rounded. In our case, we need it to be cut. So we are changes cornerFamily to cut.

<com.google.android.material.imageview.ShapeableImageView

android:id="@+id/imageViewCircleWithStroke"

app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.App.CornerCut"

android:layout_width="150dp"

android:layout_height="150dp"

android:layout_marginTop="10dp"

android:src="@mipmap/ic_launcher"

app:layout_constraintTop_toTopOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintStart_toStartOf="parent"/>

in style.xml :

<style name="ShapeAppearanceOverlay.App.CornerCut" parent="">

<item name="cornerSize">15dp</item>

<item name="cornerFamily">cut</item>

</style>

By changing the cornerSize, we can make different shapes like diamond, hexagon, etc.

Dynamically using Kotlin

val radius = resources.getDimension(R.dimen.corner_radius)

val shapeAppearanceModel = shapeableImageView.shapeAppearanceModel.toBuilder()

.setAllCorners(CornerFamily.CUT,radius)

.build()

shapeableImageView.shapeAppearanceModel = shapeAppearanceModel

setAllCorners() used to set both cornerFamily and cornerRadius.

Selected Corner Radius / Cut imageview

Selected cornet radius / cut imageview

Using XML

To set corner radius for the selected position, we need to use both cornerSize and cornerFamily for the particular position.

For example, check the below example to set the corner radius for the right top position of the imageview.

in style.xml :

<style name="ShapeAppearanceOverlay.App.SelectedCornerRadius" parent="">

<item name="cornerSizeTopRight">75dp</item>

<item name="cornerFamilyTopRight">rounded</item>

</style>

for the cut corner radius in style.xml :

<style name="ShapeAppearanceOverlay.App.SelectedCornerCut" parent="">

<item name="cornerSizeTopRight">75dp</item>

<item name="cornerFamilyTopRight">cut</item>

</style>

same way for the multiple corners, we need to add cornerRadius and cornerFamily.

multiple selected corner imageview

in style.xml :

<style name="ShapeAppearanceOverlay.App.SelectedCornerRadius" parent="">

<item name="cornerSizeTopRight">75dp</item>

<item name="cornerFamilyTopRight">rounded</item>

<item name="cornerSizeBottomLeft">75dp</item>

<item name="cornerFamilyBottomLeft">rounded</item>

</style>



<style name="ShapeAppearanceOverlay.App.SelectedCornerCut" parent="">

<item name="cornerSizeTopRight">75dp</item>

<item name="cornerFamilyTopRight">cut</item>

<item name="cornerSizeBottomLeft">75dp</item>

<item name="cornerFamilyBottomLeft">cut</item>

</style>

Dynamically using Kotlin

val radius = resources.getDimension(R.dimen.corner_radius)

val shapeAppearanceModel = shapeableImageView.shapeAppearanceModel.toBuilder()

.setTopRightCorner(CornerFamily.ROUNDED,radius)

.build()

shapeableImageView.shapeAppearanceModel = shapeAppearanceModel

setTopRightCorner() used to set the corner radius for the top right corner. To set multiple corners we can use setBottomLeftCorner(), setTopLeftCorner() and setBottomRightCorner() .

That’s it.

Thanks for reading.
