我在android中使用Facebook sdk 4.4.0，我希望使用图形请求获取用户的当前个人资料图片。怎么做？
我见过人们使用
https://graph.facebook.com/me/picture?access_token=ACCESS_TOKEN
用于提取个人资料图片的API，但我无法想象如何从中提取个人资料图片。

您需要调用GraphRequest API来获取用户的所有详细信息，其中API还会提供当前个人资料图片的网址。
Bundle params = new Bundle();
params.putString("fields", "id,email,gender,cover,picture.type(large)");
new GraphRequest(AccessToken.getCurrentAccessToken(), "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= BitmapFactory.decodeStream(profilePicUrl .openConnection().getInputStream());
mImageView.setBitmap(profilePic);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}).executeAsync();

从最后的sdk 4.5.0
开始 String url;
Bundle parametersPicture = new Bundle();
parametersPicture.putString("fields", "picture.width(150).height(150)");
GraphResponse lResponsePicture = new GraphRequest(AccessToken.getCurrentAccessToken(), "/me/",
parametersPicture, null).executeAndWait();
if (lResponsePicture != null && lResponsePicture.getError() == null &&
lResponsePicture.getJSONObject() != null) {
url = lResponsePicture.getJSONObject().getJSONObject("picture")
.getJSONObject("data").getString("url");
}

你可以用两种不同的方式来做到这一点。
Way1：集成图形API支持 https://developers.facebook.com/docs/graph-api/reference/user/picture/
Way2：通过Get Call http：// graph.facebook.com/@facebook-Id}/picture?width=x&height=y
其中x和y可以是任何整数，例如100

如果你想要真正的大图片，你必须要规范。至少一种尺寸的图片 - 例如
String profileImg = "https://graph.facebook.com/" + loginResult.getAccessToken().getUserId() + "/picture?type=large&width=1080";
此外，您可以指定两种尺寸（添加＆amp; height = some_val），但Facebook会裁剪此个人资料图片。

从Facebook获取图片
Start依赖
String image_url = "http://graph.facebook.com/" + Profile.getCurrentProfile().getId() + "/picture?type=large";
Glide.with(activity)
.load(image_url)
.into(imageView);

只需拨打此网址：
graph.facebook.com/<facebook_user_id>/picture?type=large
类型可以是大的，正常的或小的。
另一种方法是使用ProfilePictureView
<com.facebook.login.widget.ProfilePictureView
android:id="@+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
facebook:preset_size="small"/>
之后你可以在代码中设置这样的facebook id
profilePictureView.setProfileId(facebookUserId);
