延长提到的在线资源后，我无法理解什么是错在code。任何帮助将AP preciated。

解决方案

如果您使用的是Facebook的默认登录按钮后，除无需设置onclick事件。您可以使用它是这样的。

loginButton =（LoginButton）findViewById（R.id.login_button）;名单＆LT;字符串＆GT; permissionNeeds = Arrays.asList（user_photos，电子邮件，user_birthday，public_profile，AccessToken）;loginButton.registerCallback（callbackManager，新FacebookCallback＆LT; LoginResult＆GT; （）{@覆盖公共无效的onSuccess（LoginResult loginResult）{的System.out.println（的onSuccess）;字符串accessToken = loginResult.getAccessToken（）.getToken（）;Log.i（accessToken，accessToken）;GraphRequest请求= GraphRequest.newMeRequest（loginResult.getAccessToken（），新GraphRequest.GraphJSONObjectCallback（）{@覆盖公共无效onCompleted（的JSONObject对象，GraphResponse响应）{Log.i（LoginActivity，response.toString（））;尝试 {ID = object.getString（ID）;尝试 {URL profile_pic =新的URL（http://graph.facebook.com/+编号+？/图像类型=大）;Log.i（profile_picprofile_pic +）;}赶上（MalformedURLException异常E）{e.printStackTrace（）;}字符串名称= object.getString（姓名）;字符串email = object.getString（电子邮件）;字符串性别= object.getString（性别）;字符串的生日= object.getString（生日）;}赶上（JSONException E）{e.printStackTrace（）;}}}）;捆绑参数=新包（）;parameters.putString（域，编号，姓名，电子邮箱，性别，生日）;request.setParameters（参数）;request.executeAsync（）;}@覆盖公共无效OnCancel的（）{的System.out.println（OnCancel的」）;}@覆盖公共无效onerror的（FacebookException除外）{的System.out.println（onError的）;Log.v（LoginActivity，exception.getCause（）的toString（））;}}）;

如果您使用自定义的Facebook按钮，不仅仅是这里facebook使用自定义按钮登录

After implementing the following , OnCancel method is being called :

<activity
            android:name=".FbLoginActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:label="@string/title_activity_fb_login"
            android:theme="@style/FullscreenTheme" >
        </activity>

        <meta-data
            android:name="com.facebook.sdk.ApplicationId"
            android:value="xxxxxxxxxxxxxx"/>
        <provider android:authorities="com.facebook.app.FacebookContentProvider456579934439214"
            android:name="com.facebook.FacebookContentProvider"
            android:exported="true" />


        <activity android:name="com.facebook.FacebookActivity"
            android:configChanges=
                "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
            android:theme="@android:style/Theme.Translucent.NoTitleBar"
            android:label="@string/app_name" />

In the Activity:

public class FbLoginActivity extends Activity {

    TextView tvTermsLink;
    CallbackManager callbackManager;
    String TAG="FbLoginActivity";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        FacebookSdk.sdkInitialize(getApplicationContext());
        callbackManager = CallbackManager.Factory.create();

        setContentView(R.layout.activity_fb_login);
        LoginButton loginButton = (LoginButton) findViewById(R.id.authButton);

        loginButton.setReadPermissions(Arrays.asList("user_location", "email", "user_friends", "user_birthday", "user_likes", "user_work_history", "user_relationships", "user_relationship_details",
                "user_education_history"));


        tvTermsLink=(TextView) findViewById(R.id.fbl_tv_termsLink);
        tvTermsLink.setText(Html.fromHtml("By logging in you accept the <a href=\"http://crownit.in/terms\">Terms & Conditions</a> "));

        tvTermsLink.setMovementMethod(LinkMovementMethod.getInstance());




        loginButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

              LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(LoginResult loginResult) {

                }

                @Override
                public void onCancel() {

                }

                @Override
                public void onError(FacebookException e) {

                }
            });


            }
        });

    }

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

After prolonged referring the online resources, I am not able to understand whats wrong in the code. Any help will be appreciated.

解决方案

If you are using facebook's default login button than no need to set onclick event. you can use it like this.

loginButton = (LoginButton) findViewById(R.id.login_button);

List < String > permissionNeeds = Arrays.asList("user_photos", "email",
	"user_birthday", "public_profile", "AccessToken");
loginButton.registerCallback(callbackManager,
new FacebookCallback < LoginResult > () {@Override
	public void onSuccess(LoginResult loginResult) {

		System.out.println("onSuccess");

		String accessToken = loginResult.getAccessToken()
			.getToken();
		Log.i("accessToken", accessToken);

		GraphRequest request = GraphRequest.newMeRequest(
		loginResult.getAccessToken(),
		new GraphRequest.GraphJSONObjectCallback() {@Override
			public void onCompleted(JSONObject object,
			GraphResponse response) {
				Log.i("LoginActivity", response.toString());
				try {
					id = object.getString("id");
					try {
						URL profile_pic = new URL(
							"http://graph.facebook.com/" + id + "/picture?type=large");
						Log.i("profile_pic",
						profile_pic + "");

					} catch (MalformedURLException e) {
						e.printStackTrace();
					}
					String name = object.getString("name");
					String email = object.getString("email");
					String gender = object.getString("gender");
					String birthday = object.getString("birthday");
				} catch (JSONException e) {
					e.printStackTrace();
				}
			}
		});
		Bundle parameters = new Bundle();
		parameters.putString("fields",
			"id,name,email,gender, birthday");
		request.setParameters(parameters);
		request.executeAsync();
	}

	@Override
	public void onCancel() {
		System.out.println("onCancel");
	}

	@Override
	public void onError(FacebookException exception) {
		System.out.println("onError");
		Log.v("LoginActivity", exception.getCause().toString());
	}
});
