SherlockFragmentActivity - 如何在其中创建标签和setContent？

Question

我正在使用SherlockFragmentActivity创建标签。这是我第一次开始研究这种东西。我想创建四个选项卡联系人，组，图库，活动选项卡，其中包含完整功能。我已创建这些选项卡，但我发现为每个选项卡添加单独的活动有点困难。如果你可以提供任何类型的帮助，如一些教程，或一些提示，以便我学习它们并在我的appplication中应用。我非常感谢你。

我的问题与loadermanager有关，因为我的应用程序在getLoaderManager（）时停止了.initLoader（0，null，this）;函数被调用。我在下面给出了我的装载机功能

public Loader<Cursor> onCreateLoader(int id, Bundle args) {
             // This is called when a new Loader needs to be created.  This
            // sample only has one Loader, so we don't care about the ID.
            // First, pick the base URI to use depending on whether we are
            // currently filtering.
            Uri baseUri;
            if (mCurFilter != null) {
                baseUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_FILTER_URI,
                          Uri.encode(mCurFilter));
            } else {
                baseUri = ContactsContract.Contacts.CONTENT_URI;
            }

            // Now create and return a CursorLoader that will take care of
            // creating a Cursor for the data being displayed.
            String select = "((" + ContactsContract.Contacts.DISPLAY_NAME + " NOTNULL) AND ("
                    + ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1) AND ("
                    + ContactsContract.Contacts.DISPLAY_NAME + " != '' ))";
            return new CursorLoader(getActivity(), baseUri,
                    CONTACTS_SUMMARY_PROJECTION, select, null,
                    ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
        }

        public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
            // Swap the new cursor in.  (The framework will take care of closing the
            // old cursor once we return.)
            mAdapter.swapCursor(data);

            // The list should now be shown.
            if (isResumed()) {
                setListShown(true);
            } else {
                setListShownNoAnimation(true);
            }
        }

        public void onLoaderReset(Loader<Cursor> loader) {
            // This is called when the last Cursor provided to onLoadFinished()
            // above is about to be closed.  We need to make sure we are no
            // longer using it.
            mAdapter.swapCursor(null);
        }
