Hi guys I a have contact list view with Quick contact badge.It displaying square images but my requirement is to show circular quick contact badge (like below screen shot). Plz let me know how can I achieve this. Thanks in advance.

推荐答案

下面是两种方法来创建圆形的图像。你只需要通过位图图像，使其循环。

Below are two methods for creating circular images. you just have to pass bitmap image to make it circular.

/**
 * To make image in a round shape. Use this method if you want to specify required height and width
 * 
 * @param i
 */
public static Bitmap getRoundedShape(Bitmap scaleBitmapImage, int i) {
    int targetWidth = i;
    int targetHeight = i;
    Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight,
            Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(targetBitmap);
    Path path = new Path();
    path.addCircle(((float) targetWidth - 1) / 2,
            ((float) targetHeight - 1) / 2,
            (Math.min(((float) targetWidth), ((float) targetHeight)) / 2),
            Path.Direction.CCW);
    canvas.clipPath(path);
    Bitmap sourceBitmap = scaleBitmapImage;
    canvas.drawBitmap(sourceBitmap, new Rect(0, 0, sourceBitmap.getWidth(),
            sourceBitmap.getHeight()), new Rect(0, 0, targetWidth,
            targetHeight), null);
    return targetBitmap;
}

/**
 * To make image in a round shape
 */

public static Bitmap getCroppedBitmap(Bitmap bitmap) {
    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
            bitmap.getHeight(), Config.ARGB_8888);
    Canvas canvas = new Canvas(output);

    final int color = 0xff424242;
    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);
    paint.setColor(color);
    // canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
    canvas.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2,
            bitmap.getWidth() / 2, paint);
    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);
    // Bitmap _bmp = Bitmap.createScaledBitmap(output, 60, 60, false);
    // return _bmp;
    return output;
}
