</RelativeLayout>

XML for round shape

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#CCCCCC"/>
    <padding android:left="1dp"
        android:top="1dp"
        android:right="1dp"
        android:bottom="1dp"/>


    <corners android:radius="15dp"/>
</shape>

Answer 1

Just use the ShapeableImageView in the Material Components library.
Something like:

  <com.google.android.material.imageview.ShapeableImageView
      ...
      app:shapeAppearanceOverlay="@style/roundedCornersImageView"
      app:srcCompat="@drawable/ic_image" />

with:

  <style name="roundedCornersImageView" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">xxdp</item>
  </style>

*Note: it requires at least the version 1.2.0-alpha03 .

Answer 2

You can use Glide

Just write extension function for ImageView:

1. To make rectangle image with rounded corners

    fun ImageView.loadImageWithCustomCorners(@DrawableRes resId: Int, radius: Int) = Glide.with(this).load(resId).transform(RoundedCorners(radius)).into(this)

2. To make square image with rounded corners

    fun ImageView.loadImageWithCustomCorners(@DrawableRes resId: Int, radius: Int) = Glide.with(this).load(resId).transform(CenterCrop(), RoundedCorners(radius)).into(this)

Using in code

iv_service_avatar.loadImageWithCustomCorners(R.drawable.ic_default_avatar, 15)

iv_service_avatar it`s ImageView ID

Answer 3

You should call setClipToOutline to true when using background with radius it only calls programmatically can not set by XML

imageView.setClipToOutline(true);

Answer 4

you can put your ImageView to a CardView and use the app:cardCornerRadius for set image corner

Answer 5

For Rounded Corner you can use following Custom Layout:

Java: RoundedCornerImageLayout.java

public class RoundedCornerImageLayout extends FrameLayout {
    private final static float CORNER_RADIUS = 10.0f;
    private float cornerRadius;

    public RoundedCornerImageLayout(Context context) {
        super(context);
        init(context, null, 0);
    }

    public RoundedCornerImageLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context, attrs, 0);
    }

    public RoundedCornerImageLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init(context, attrs, defStyle);
    }

    private void init(Context context, AttributeSet attrs, int defStyle) {
        DisplayMetrics metrics = context.getResources().getDisplayMetrics();
        cornerRadius = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, CORNER_RADIUS, metrics);
        setLayerType(View.LAYER_TYPE_SOFTWARE, null);
    }


    @Override
    protected void dispatchDraw(Canvas canvas) {
        int count = canvas.save();

        final Path path = new Path();
        path.addRoundRect(new RectF(0, 0, canvas.getWidth(), canvas.getHeight()), cornerRadius, cornerRadius, Path.Direction.CW);
        canvas.clipPath(path, Region.Op.INTERSECT);

        canvas.clipPath(path);
        super.dispatchDraw(canvas);
        canvas.restoreToCount(count);
    }
}

You can change the private final static float CORNER_RADIUS = 10.0f; according to your requirement

in XMl file

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".RoundedImageViewActivity">
    <com.example.stackdemo.ui.RoundedCornerImageLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent">
        <ImageView
            android:layout_width="150dp"
            android:layout_height="150dp"
            android:src="@drawable/ocean"
            android:scaleType="centerCrop"/>
    </com.example.stackdemo.ui.RoundedCornerImageLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

Output for above code is:

I hope this helps you

Answer 6

Use androidx.cardview.widget.CardView in such way:

<androidx.cardview.widget.CardView
                    android:layout_width="148dp"
                    android:layout_height="148dp"
                    card_view:cardCornerRadius="4dp"
                    >

                    <ImageView
                        android:id="@+id/some_id"
                        android:layout_width="148dp"
                        android:layout_height="148dp"
                        android:layout_gravity="center_vertical"
                        android:radius="10dp"
                        android:scaleType="fitXY"
                        tools:background="#EDEDED" />
                </androidx.cardview.widget.CardView>

card_view will be unresolved, so in order to resolve it, add xmlns:card_view="http://schemas.android.com/apk/res-auto" to the root element.
