使用新的API和您的Facebook的自定義按鈕，你可以使用以下代碼：

在你的gradle文件中放置下面的gradle：

compile'com.facebook.android:facebook-android-sdk:4.20.0'Newer sdk does not need initializaion.privateCallbackManager callbackManager;@OverrideprotectedvoidonCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);FacebookSdk.sdkInitialize(LoginActivity.this);//Is now depricatedsetContentView(R.layout.activity_login);callbackManager=CallbackManager.Factory.create();}

onActivityResult：

@OverrideprotectedvoidonActivityResult(int requestCode,int resultCode,Intent data){super.onActivityResult(requestCode,resultCode,data);callbackManager.onActivityResult(requestCode,resultCode,data);}

按鈕點(diǎn)擊：

@OverridepublicvoidonClick(View v){switch(v.getId()){caseR.id.btn_f_sign_in_login:LoginManager.getInstance().logInWithReadPermissions(this,Arrays.asList("user_friends","email","public_profile"));LoginManager.getInstance().registerCallback(callbackManager,newFacebookCallback<LoginResult>(){@OverridepublicvoidonSuccess(LoginResult loginResult){setFacebookData(loginResult);}@OverridepublicvoidonCancel(){}@OverridepublicvoidonError(FacebookException exception){}});break;}}

setFacebookData：

privatevoidsetFacebookData(final LoginResult loginResult){GraphRequest request=GraphRequest.newMeRequest(loginResult.getAccessToken(),newGraphRequest.GraphJSONObjectCallback(){@OverridepublicvoidonCompleted(JSONObject object,GraphResponse response){// Application codetry{Log.i("Response",response.toString());String email=response.getJSONObject().getString("email");String firstName=response.getJSONObject().getString("first_name");String lastName=response.getJSONObject().getString("last_name");String gender=response.getJSONObject().getString("gender");Profile profile=Profile.getCurrentProfile();String id=profile.getId();String link=profile.getLinkUri().toString();Log.i("Link",link);if(Profile.getCurrentProfile()!=null){Log.i("Login","ProfilePic"+Profile.getCurrentProfile().getProfilePictureUri(200,200));}Log.i("Login"+"Email",email);Log.i("Login"+"FirstName",firstName);Log.i("Login"+"LastName",lastName);Log.i("Login"+"Gender",gender);}catch(JSONExceptione){e.printStackTrace();}}});Bundle parameters=newBundle();parameters.putString("fields","id,email,first_name,last_name,gender");request.setParameters(parameters);request.executeAsync();}

獲取Facebook朋友誰(shuí)下載了你的應(yīng)用程序：

替換parameters.putString（“fields”，“id，email，first_name，last_name”）;

帶有parameters.putString（“fields”，“id，email，first_name，last_name，friends”）;

添加以下邏輯來(lái)獲取朋友數(shù)據(jù)：

if(object.has("friends")){JSONObject friend=object.getJSONObject("friends");JSONArray data=friend.getJSONArray("data");for(int i=0;i<data.length();i++){Log.i("idddd",data.getJSONObject(i).getString("id"));}}
