I\'d Like to make any image from my ImageView
to be circular with a border.
I searched but couldn\'t find any useful information (anything that I tried
This will do the trick:
rectangle.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@android:color/transparent" />
<padding android:bottom="-14dp" android:left="-14dp" android:right="-14dp" android:top="-14dp" />
</shape>
circle.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="oval"
android:useLevel="false" >
<solid android:color="@android:color/transparent" />
<stroke
android:width="15dp"
android:color="@color/verification_contact_background" />
</shape>
profile_image.xml ( The layerlist )
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/rectangle" />
<item android:drawable="@drawable/circle"/>
</layer-list>
Your layout
<ImageView
android:id="@+id/profile_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/default_org"
android:src="@drawable/profile_image"/>
You can simply use CardView without any external Library
<androidx.cardview.widget.CardView
android:id="@+id/roundCardView"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_centerHorizontal="true"
android:elevation="0dp"
app:cardCornerRadius="20dp">
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:src="@drawable/profile" />
</androidx.cardview.widget.CardView>
Create a CustomImageview then simply override its onDraw()
method follows:
@Override
protected void onDraw(Canvas canvas) {
float radius = this.getHeight()/2;
Path path = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
path.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
In case you want the code for the custom widget as well:-
CircularImageView.java
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Path;
import android.graphics.RectF;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
import androidx.annotation.Nullable;
public class CircularImageView extends ImageView {
private Drawable image;
public CircularImageView(Context context) {
super(context);
init(null, 0);
}
public CircularImageView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
init(attrs, 0);
}
public CircularImageView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(attrs, defStyleAttr);
}
@Override
protected void onDraw(Canvas canvas) {
float radius = this.getHeight()/2;
Path path = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
path.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
private void init(AttributeSet attrs, int defStyle) {
TypedArray a = Utils.CONTEXT.getTheme().obtainStyledAttributes(attrs, R.styleable.CircularImageView, 0, 0);
try {
image = a.getDrawable(R.styleable.CircularImageView_src);
} finally {
a.recycle();
}
this.setImageDrawable(image);
}
}
Also, add the following code to your res/attrs.xml to create the required attribute:-
<declare-styleable name="CircularImageView">
<attr name="src" format="reference" />
</declare-styleable>
This is a relatively old question, but you can just make a circle border in the drawable folder (let's assume the xml file will be called circle_border
)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="@android:color/transparent" />
<!-- If you want a padding -->
<padding android:top="4dp" android:left="4dp" android:right="4dp" android:bottom="4dp" />
<!-- If you want the circle border to have a color -->
<strong android:width="1dp" android:color="#FFFFFF" />
</shape>
Then you can use it as the background of the ImageView
<ImageView
android:background="@drawable/circle_border"
<!-- other attributes here -->
/>
As was described in Orhan Obut's answer but with the changes:
<ImageView
android:layout_width="0dp" //or use your own value
android:layout_height="match_parent"
android:src="@drawable/img"
android:layout_weight="75" />// in case of use of weight
to avoid stretches of the image. And img.xml:
<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/profile" />
<item android:drawable="@drawable/circle" /></layer-list>
(without changes), and circle.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadiusRatio="2"
android:shape="ring"
android:thickness="300dp"
android:useLevel="false">
<solid android:color="@android:color/white"/>
<stroke
android:width="2dp"
android:color="@android:color/black"/>
</shape>
here the thickness of the ring gotten maximal - 1000dp
and radiusRatio is a half of image width(max ring width, yes?) - 2
and the stroke is for required border if needed.
I used square png image ( profile.png ), btw. With same width and height.
This is correct for arbitrary ImageView dimentions.
Just use the ShapeableImageView
provided by the Material Components Library.
Somethig like:
<com.google.android.material.imageview.ShapeableImageView
app:shapeAppearanceOverlay="@style/roundedImageViewRounded"
app:strokeColor="@color/....."
app:strokeWidth="1dp"
...
/>
with:
<style name="roundedImageViewRounded">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">50%</item>
</style>
Note: it requires at least the version 1.2.0-alpha03
.
