How to put an imageView in Circular format inside an Android fragment?

In my case, I was only able to use one to make a ImageView round using an external library, in my case the CircleImageView . Home Just add the dependency on Gradle :

compile 'de.hdodenhof:circleimageview:2.0.0'

And use CircleImageView instead of ImageView in xml:

<de.hdodenhof.circleimageview.CircleImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="96dp"
    android:layout_height="96dp"
    android:src="@drawable/profile" // Sua imagem
    app:civ_border_width="0dp" // Se quiser pode colocar uma borda na imagem tambem
    app:civ_border_color="#FF000000"/> // Cor da borda

For more information, see the official API link.

Good evening,

I tried using android.support.v4.widget.CircleImageView, but I could not, so one solution I found was to implement my own class (MyCircleImageView) inheriting from ImageView. It is a very simple and small class. Can be used in place of ImageView in layout.

/**

public class MyCircleImageView extends ImageView {

private Paint paint;

...
Construtores (inicialização, cria o objeto paint)
... 

@Override
public void onDraw(Canvas canvas) {
    super.onDraw(canvas);

    paint.setStrokeWidth(2);
    paint.setColor(Color.WHITE);
    paint.setStyle(Paint.Style.STROKE);

    float largura = getWidth();
    float altura  = getHeight();

    float x = largura / 2;
    float y = altura / 2;
    float raio = 0;
    if (largura > altura) {
        raio = (altura)/2;
    } else {
        raio = (largura) / 2;
    }

    canvas.drawCircle(x, y, raio, paint);

    paint.setStrokeWidth(300);
    canvas.drawCircle(x, y, raio + 150, paint);
}
