I am getting image urls from server with square shape I have to make it to rounded corner images.Actually I am using volley library ,I know how to create round corner images using universal image loader and picasso libraries.In volley library I am setting image in network imageview like setimageUrl please help me
holder.ivImage.setImageUrl(url, imageLoader);
I found an source code which makes imageview rounded shape e.g. https://github.com/hdodenhof/CircleImageView. which was extending imageview, I just make it extend NetworkImageView. Everything working fine for me. If you don't want to use above circular image view, you have to extend NetworkImageView class and customize to meet your needs.
you need to extend NetworkImageView class and create own view
Java: CircularNetworkImageView
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.RectF;
import android.graphics.Bitmap.Config;
import android.graphics.PorterDuff.Mode;
import android.graphics.drawable.BitmapDrawable;

import com.android.volley.toolbox.NetworkImageView;
public class CircularNetworkImageView extends NetworkImageView {
Context mContext;
public CircularNetworkImageView(Context context) {
super(context);

}

this(context, attrs, 0);
mContext = context;
}
public CircularNetworkImageView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
mContext = context;
}
@Override
public void setImageBitmap(Bitmap bm) {
if(bm==null) return;
setImageDrawable(new BitmapDrawable(mContext.getResources(),
getCircularBitmap(bm)));
}
/**

* <br/>Also constrains the circle to the leftmost part of the image
*

*/
public Bitmap getCircularBitmap(Bitmap bitmap) {
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
bitmap.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);
int width = bitmap.getWidth();
if(bitmap.getWidth()>bitmap.getHeight())
width = bitmap.getHeight();
final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, width, width);
final RectF rectF = new RectF(rect);
final float roundPx = width / 2;
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;
}
}
XML
<com.example.own.CircularNetworkImageView
android:id="@+id/image"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_marginRight="10dp"/>
Usage:
CircularNetworkImageView image = (CircularNetworkImageView) view.findViewById(R.id.image);
private ImageLoader netImageLoader=AppController.getInstance().getImageLoader();
image.setImageUrl("imageurl", netImageLoader);

You can create a custom class which extends NetworkImageView(Volley).

you can use CardView.
<android.support.v7.widget.CardView
app:cardCornerRadius="@dimen/spacing_tiny">
<com.android.volley.toolbox.NetworkImageView>
...
/>
</android.support.v7.widget.CardView>
This is how I did it:
In the volley library, copy the class called "NetworkImageView" and name it "NetworkImageViewCircle".
private void setAnimateImageBitmap(final Bitmap bitmap, boolean fadeIn) { final Bitmap bmp; bmp = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888); BitmapShader shader = new BitmapShader(bitmap, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP); float radius = Math.min(bitmap.getWidth(), bitmap.getHeight()) / 5; Canvas canvas = new Canvas(bmp); Paint paint = new Paint(); paint.setAntiAlias(true); paint.setShader(shader); RectF rect = new RectF(0, 0, bitmap.getWidth(), bitmap.getHeight()); canvas.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2, bitmap.getWidth() / 2, paint); . . .
This made the trick for me. hope it helps.
That worked for me
<android.support.v7.widget.CardView
android:id="@+id/container"
android:layout_width="80dp"
android:layout_height="80dp"
app:cardCornerRadius="5dp"
app:cardElevation="0dp" >
<com.android.volley.toolbox.NetworkImageView
android:id="@+id/thumb"
android:layout_width="80dp"
android:layout_height="80dp"/>
</android.support.v7.widget.CardView>
Volley has nothing to do with round corner image .
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 networkimageview.
// 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/ic_launcher"/>
<item android:drawable="@drawable/circle"/>
</layer-list>
and put it as background to your networkimageview.
<com.android.volley.toolbox.NetworkImageView
android:id="@+id/networkImageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:background="@drawable/img"
android:src="@drawable/ic_launcher" />
You'll have something like that.
