}
有没有其他/更好的方法可以做到这一点


非常感谢

在bundle中传递所需参数,因为

graph.facebook.com//picture?type=large

我做过这样的事情:

首先,您需要调用
graphrequestapi
以获取用户的所有详细信息,其中
API
还提供当前配置文件图片的
URL

Bundle params = new Bundle();
params.putString("fields", "id,email,gender,cover,picture.type(large)");
new GraphRequest(token, "me", params, HttpMethod.GET,
        new GraphRequest.Callback() {
            @Override
            public void onCompleted(GraphResponse response) {
                if (response != null) {
                    try {
                        JSONObject data = response.getJSONObject();
                        if (data.has("picture")) {
                            String profilePicUrl = data.getJSONObject("picture").getJSONObject("data").getString("url");
                            Bitmap profilePic = getFacebookProfilePicture(profilePicUrl);
                            // set profilePic bitmap to imageview
                        }
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }
}).executeAsync();
您可以使用这个方法,它从
URL
返回用户的当前配置文件图片,我们从上面的
graphrequestapi
获得该图片

public static Bitmap getFacebookProfilePicture(String url){
    Bitmap bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
    return bitmap;
}
