How to convert ImageView's images in circular format

Question

Currently I am working on application in which I flip images on button click. But problem is here that I am using ImageView's images from xml and these are in rectangular format. I want to use these images in circular format.

I search on internet about this problem and I found that most of solutions uses Bitmap images. This means I need to convert Images in bitmap format. How can I convert these.?
Note:- I am using images from Drawable folder.

I found these solutions but don't know how to use them:
How to make an ImageView with rounded corners?

second one:
How to create a circular ImageView in Android?

How to use these solution for my application?
So how to convert images in circular shape?

Here is my MainActivity.java class which I used to flip images on button click.

Answer 1

Simple

in your xml file:

just drag imageview and put any image from your drawable folder

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"       
    android:layout_centerHorizontal="true"       
    android:src="@drawable/image" />

in your main activity:

Get all control on the image view. By using bitmap we can crop image into circular form and show in the same imageview. Not only into circular form, we can convert it into any shape like square or so using this.

public class MainActivity extends Activity {

static ImageView imageView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    imageView=(ImageView)findViewById(R.id.imageView1);

    Bitmap bitmap=BitmapFactory.decodeResource(getResources(), R.drawable.image);

    imageView.setImageBitmap(getCircleBitmap(bitmap));
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}


public static Bitmap getCircleBitmap(Bitmap bitmap) {


    //crop to circle 
    Bitmap output;
    //check if its a rectangular image
    if (bitmap.getWidth() > bitmap.getHeight()) {
        output = Bitmap.createBitmap(bitmap.getHeight(), bitmap.getHeight(), Config.ARGB_8888);
    } else {
        output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getWidth(), Config.ARGB_8888);
    }
    Canvas canvas = new Canvas(output);

    float r = 0;

    if (bitmap.getWidth() > bitmap.getHeight()) {
        r = bitmap.getHeight() / 2;
    } else {
        r = bitmap.getWidth() / 2;
    }

    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());


    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);

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

    return output;
   }

}

Answer 2

Try using this CircularImageView library found at github.

XML:

<com.mikhaellopez.circularimageview.CircularImageView
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:src="@drawable/image"
        app:border_color="#EEEEEE"
        app:border_width="10"
        app:shadow="true" />

Java:

CircularImageView circularImageView = (CircularImageView)findViewById(R.id.yourCircularImageView);
circularImageView.setBorderColor(getResources().getColor(R.color.GrayLight));
circularImageView.setBorderWidth(10);
circularImageView.addShadow();
