如何从圆形的URL中加载图像视图中的图像？

Question

我创建了一个Android应用程序,我想在圆形的图像视图中显示图像.

我的代码是:

    private class LoadImage extends AsyncTask<String, Void, String> 
    {
        Bitmap image=null;
        @Override
        protected String doInBackground(String... params) 
        {
            try 
            {
                URL url = new URL(imgUrl);
                image = BitmapFactory.decodeStream(url.openConnection().getInputStream());              
                image=Global.getRoundedShape(image);                                
            } 
            catch (Exception e) 
            {
                e.printStackTrace();
            }
            return "Executed";
        }
        @Override
        protected void onPostExecute(String code) 
        {
            try
            {
                profilepic.setImageBitmap(image);
            }
            catch (Exception e) 
            {
                e.printStackTrace();
            }
        }    
    }


public static Bitmap getRoundedShape(Bitmap scaleBitmapImage) 
{
    int targetWidth = 168;
    int targetHeight = 166;
    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;
}

我使用此代码,但加载Image需要很多负载.

那么,有没有选择让它快速？

尝试以下代码: -

首先下载通用加载器lib并编写下面的代码.

https://github.com/nostra13/Android-Universal-Image-Loader/downloads

int rounded_value = 120;    

DisplayImageOptions options = new DisplayImageOptions.Builder().cacheInMemory(true).cacheOnDisc(true).displayer(new RoundedBitmapDisplayer(rounded_value)).build();

ImageLoader.getInstance().displayImage(strUrl1, imgThumb1,options);
