Imageview in Circular Through Xml

ImageView in circular through XML

You can make a simple circle with white border and transparent content with shape.

// res/drawable/circle.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:innerRadius="0dp"
    android:shape="ring"
    android:thicknessRatio="1.9"
    android:useLevel="false" >
    <solid android:color="@android:color/transparent" />

    <stroke
        android:width="10dp"
        android:color="@android:color/white" />
</shape>

Then make a layerlist drawable and put it as background to your imageview.

// res/drawable/img.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item android:drawable="@drawable/circle"/>    
    <item android:drawable="@drawable/ic_launcher"/>

</layer-list>

and put it as background to your imageview.

   <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/img"/>

You'll have something like that.

Circular Image View in Android without using any external library

You can put your ImageView inside CardView and set its corner radius.
Simple example

<android.support.v7.widget.CardView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        card_view:cardCornerRadius="25dp"
        card_view:cardPreventCornerOverlap="false">

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"/>
    </android.support.v7.widget.CardView>

Note that the corner radius should be twice shorter than image size.

What is the best way to create a circular ImageView?

You can use the next library. Add Gradle dependency:

compile 'de.hdodenhof:circleimageview:2.2.0'

Then simply add XML view:

<de.hdodenhof.circleimageview.CircleImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/profile_image"
    android:layout_width="96dp"
    android:layout_height="96dp"
    android:src="@drawable/profile"
    app:civ_border_width="2dp"
    app:civ_border_color="#FF000000"/>

Android code to make imageView round not working

Major problem will be when you use Picasso to set image again to set to imageView view bounds not to the its background that you create.

If you programmatically set a one it will override your background!

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <shape android:shape="oval">
            <solid android:color="@color/colorPrimary"/>
        </shape>
    </item>
</selector>

You can set this as background of your view.Then try to use view.setBackgroundResource(R.drawable.icon_img); . you will notice the change!

You can go through Add a background image to shape in xml Android

Mask ImageView with round corner background

to check the various ways people tried out here!

But with Picasso you can do this directly with out other 3rd parties.

  final ImageView imageView = (ImageView) findViewById(R.id.group_icon_jsoup);
    Picasso.with(YourActivity.this).load("http://i.imgur.com/DvpvklR.png")
            .resize(100, 100)
            .into(imageView, new Callback() {
                @Override
                public void onSuccess() {
                    Bitmap imageBitmap = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
                    RoundedBitmapDrawable imageDrawable = RoundedBitmapDrawableFactory.create(getResources(), imageBitmap);
                    imageDrawable.setCircular(true);
                    imageDrawable.setCornerRadius(Math.max(imageBitmap.getWidth(), imageBitmap.getHeight()) / 2.0f);
                    imageView.setImageDrawable(imageDrawable);
                }
                @Override
                public void onError() {
                    imageView.setImageResource(R.drawable.amanda);
                }
            });

Circular Imageview in android

1. Try to extend CircularImageView from ImageView instead of android.support.v7.widget.AppCompatImageView.

CircularImageView.java

package com.ferdous.stackoverflowanswer;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class CircularImageView extends ImageView {

    public CircularImageView(Context context) {
        super(context);
    }

    public CircularImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

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

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth(), h = getHeight();

        Bitmap roundBitmap = getRoundBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }

    public static Bitmap getRoundBitmap(Bitmap bmp, int radius) {
        Bitmap sBmp;

        if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
            float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
            float factor = smallest / radius;
            sBmp = Bitmap.createScaledBitmap(bmp, (int)(bmp.getWidth() / factor), (int)(bmp.getHeight() / factor), false);
        } else {
            sBmp = bmp;
        }

        Bitmap output = Bitmap.createBitmap(radius, radius,
                Bitmap.Config.ARGB_8888);


        Canvas canvas = new Canvas(output);

        final String color = "#BAB399";
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, radius, radius);

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor(color));
        canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f, radius / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
        canvas.drawBitmap(sBmp, rect, rect, paint);

        return output;
    }

}

2. In your XML, try using attribute android:src instead of app:srcCompt:

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:orientation="vertical"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:gravity="center">
   
       <com.ferdous.stackoverflowanswer.CircularImageView
           android:layout_width="200dp"
           android:layout_height="200dp"
           android:src="@drawable/dummy"
           android:background="#ff0000"/>
   
   </LinearLayout>
   

OUTPUT:

Hope this will help~
