如何在圓形佈局中動態修復圖像？

Question

我是非常新的android ..是否有可能在一個圓形的佈局動態修復圖像？我們可以使用xml代碼來做到這一點，如果是的話，你可以建議我如何編寫代碼？ 在此先感謝。

這個調用用於圓形圖像位圖。

public class ImageHelper { 
    public static Bitmap getRoundedCornerBitmap(Bitmap bitmap, int pixels) { 
     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()); 
     final RectF rectF = new RectF(rect); 
     final float roundPx = pixels; 

     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; 
    } 
}
