Answer 2

you can follow this below: on your gradle in dependencies

implementation 'com.makeramen:roundedimageview:2.3.0'

on your xml file

<com.makeramen.roundedimageview.RoundedImageView
        android:id="@+id/img_home_assistance"
        android:layout_width="match_parent"
        android:layout_height="123dp"
        app:riv_corner_radius="@dimen/padding_margin_15"
        android:layout_marginTop="6.8dp"
        android:layout_marginLeft="7.3dp"
        android:layout_marginRight="7.5dp"
        android:src="@drawable/migrate"
        android:scaleType="centerCrop"/>

Answer 3

you can try using ImageView. In Image view set

android:src="@drawable/yourimage"
android:background="@drawable/cornershape"

now use the image view in FrameLayout. so that other layouts can be placed over the ImageView

Answer 4

You can just use RoundedBitmapDrawable from Android Support Library v4. All you need is create an instance and set corner radius:

RoundedBitmapDrawable roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(getResources(), bitmap);
final float roundPx = (float) bitmap.getWidth() * 0.06f;
roundedBitmapDrawable.setCornerRadius(roundPx);

Answer 5

I was having the same problem and I simply created an image with rounded corners in Photoshop. This is not an answer that involves code or drawables.

The above suggestion with the library 'com.makeramen:roundedimageview:2.3.0' did not work for me as I actually wanted to set the background of a Relative Layout to an image with rounded corner.

Using a cardview didnt work, neither did using an image as the first view in the relative layout and manipulating the roundness of the corner.

Creating a rounded corner in photoshop did the trick.

Answer 6

Romain Guy's image with rounded corner

Use a custom Drawable that draws a rounded rectangle using Canvas.drawRoundRect(). The trick is to use a Paint with a BitmapShader to fill the rounded rectangle with a texture instead of a simple color.

Canvas canvas = new Canvas(output);

final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
final RectF rectF = new RectF(rect);
final float roundPx = pixels;

paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);

return output;
