如何在 Android 中获取 Facebook 个人资料图片

Question

我在 android 中使用 Facebook sdk 4.4.0，我想使用图形请求获取用户的当前个人资料图片。怎么做？

我看到有人用

https://graph.facebook.com/me/picture?access_token=ACCESS_TOKEN

API 提取个人资料照片，但我不知道如何从中提取个人资料照片。

Answer 1

简单地称之为 URL:

graph.facebook.com/<facebook_user_id>/picture?type=large

类型可以是大号、普通号或小号。

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像这样设置facebook id

profilePictureView.setProfileId(facebookUserId);

Answer 2

您可以通过两种不同的方式获得它。

方式一：集成图api支持 https://developers.facebook.com/docs/graph-api/reference/user/picture/

方式2：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

Answer 3

您需要调用 GraphRequest API 来获取用户的所有详细信息，其中 API 还提供 URL 当前个人资料照片。

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();

Answer 4

如果您想要真正的大图片，则必须指定规格。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 &height=some_val），但 Facebook 将裁剪此个人资料图片。

Answer 5

从上一个 sdk 4.5.0

 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");
 }

try {
String fbId="970463683015249";
URL fb_url = new URL("http://graph.facebook.com/"+fbId+"/picture?type=small");//small | noraml | large
HttpsURLConnection conn1 = (HttpsURLConnection) fb_url.openConnection();
HttpsURLConnection.setFollowRedirects(true);
conn1.setInstanceFollowRedirects(true);
Bitmap fb_img = BitmapFactory.decodeStream(conn1.getInputStream());
}catch (Exception ex) {
  ex.printStackTrace();
  }

从 Facebook 获取图像

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

依赖性

implementation 'com.github.bumptech.glide:glide:4.1.1'
