Android：将ProfilePictureView转换为Bitmap失败Facebook SDK 4.1

Question

我正在尝试从profilepictureview检索Facebook图像并将其转换为位图，但它给了我一张空白的个人资料照片。我的主要目标是将图像视图转换为CircularImageView。

https://github.com/Pkmmte/CircularImageView

代码在onCreate方法中设置：

 profilePictureView = (ProfilePictureView) findViewById(R.id.image_mainlobby);
 profilePictureView.setProfileId(userid);
 profilePictureView.setPresetSize(ProfilePictureView.LARGE);

 ImageView fbImage = ( ( ImageView)profilePictureView.getChildAt( 0));
 Bitmap    bitmap  = ( ( BitmapDrawable) fbImage.getDrawable()).getBitmap();

 ImageView im = (ImageView)findViewById(R.id.fb_profile);
 im.setImageBitmap(bitmap);

Answer 1

1）onCreate方法：

private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {

2）创建一个新类

   public DownloadImageTask(ImageView bmImage) {
   this.bmImage = bmImage;
   }

   protected Bitmap doInBackground(String... urls) {
       String urldisplay = urls[0];
       Bitmap mIcon11 = null;
       try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
       } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
       } 
         return mIcon11;
       }

       protected void onPostExecute(Bitmap result) {
        bmImage.setImageBitmap(result);
      }
  }

ImageView bmImage;

$(document).ready(function () {
    $.ajax({
        type: "GET",
        url: "jqueryXML.xml",
        dataType: "xml",
        success: function (xml) {
            $(xml).find("movie").each(function () {
                var title = $(this).find("title").text();
                $(".list ul").append("<li>" + title + "</li>");
            });
        },
        error: function () {
            alert("error");
        }
    });
});
