这是我的facebook课，它的工作非常好。 只需尝试一下，您就会从Simple Facebook中学到很多东西。 不要考虑下面的一些异常代码。

public class IjoomerFacebookSharingActivity extends Activity {

        private SimpleFacebook simpleFacebook;
        private SimpleFacebookConfiguration.Builder simpleFacebookConfigurationBuilder;
        private SimpleFacebookConfiguration simpleFacebookConfiguration;

        private String IN_MESSAGE;
        private String IN_CAPTION;
        private String IN_NAME;
        private String IN_PICTURE;
        private String IN_LINK;
        private String IN_DESCRIPTION;
        @Override
        public String[] setTabItemNames() {
            return new String[0];
        }

        @Override
        public int setTabBarDividerResId() {
            return 0;
        }

        @Override
        public int setTabItemLayoutId() {
            return 0;
        }

        @Override
        public int[] setTabItemOnDrawables() {
            return new int[0];
        }

        @Override
        public int[] setTabItemOffDrawables() {
            return new int[0];
        }

        @Override
        public int[] setTabItemPressDrawables() {
            return new int[0];
        }

        @Override
        public void onCheckedChanged(RadioGroup radioGroup, int i) {

        }

        @Override
        public int setLayoutId() {
            return R.layout.facebook_main;
        }

        @Override
        public View setLayoutView() {
            return null;
        }

        @Override
        public int setHeaderLayoutId() {
            return 0;
        }

        @Override
        public int setFooterLayoutId() {
            return 0;
        }

        @Override

            simpleFacebook = SimpleFacebook.getInstance(this);

            simpleFacebookConfigurationBuilder.setAppId(getString(R.string.facebook_app_id));
            simpleFacebookConfigurationBuilder.setPermissions(new Permissions[]{Permissions.PUBLISH_ACTION,Permissions.PUBLISH_STREAM,Permissions.EMAIL,Permissions.BASIC_INFO,Permissions.USER_PHOTOS});
            simpleFacebookConfiguration = simpleFacebookConfigurationBuilder.build();
            SimpleFacebook.setConfiguration(simpleFacebookConfiguration);

        }
