android - Android使用ShelockFragment而不是Fragment

我正在使用以下代码在Fragment之间进行切换，而不会出现任何问题：

private void showSelectedItem(int index) {
        Fragment mFragment = null;
        if (index == mLastMenuItemSelected)
            return;
        FragmentTransaction fts = getSupportFragmentManager().beginTransaction();
        if (mLastViewFragment != null) {
            fts.remove(mLastViewFragment);
        }
        switch (index) {
            case SV.MIS_ShowAllSubjects:
                mFragment = new FragmentViewAllSubjects();
                fts.replace(R.id.SubjectViewFragment, mFragment);
                txtSelectedSlideTitle.setText(UC.getString(R.string.slide_menu_main));
                break;
        }
        fts.commit();
        mLastMenuItemSelected = index;
        mSlidingMenu.showContent(true);
        mLastViewFragment = mFragment;
    }

现在我想使用SherlockFragment而不是Fragment，因为进行了此更改，因此我将创建新的Fragment为：

public class ActionbarTabsPager extends SherlockFragmentActivity {
    ViewPager mViewPager;
    TabsAdapter mTabsAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

    ...

    }
}

我想将顶部代码更改为以下代码以使用并在SherlockFragment之间切换：

private void showSelectedItem(int index) {
    SherlockFragmentActivity mFragment = null;
    if (index == mLastMenuItemSelected)
        return;
    FragmentTransaction fts = getSupportFragmentManager().beginTransaction();
    if (mLastViewFragment != null) {
        fts.remove(mLastViewFragment);
    }
    switch (index) {
        case SV.MIS_ShowAllSubjects:
            mFragment = new ActionbarTabsPager();
            fts.replace(R.id.SubjectViewFragment, mFragment);
            txtSelectedSlideTitle.setText(UC.getString(R.string.slide_menu_main));
            break;
    }
    fts.commit();
    mLastMenuItemSelected = index;
    mSlidingMenu.showContent(true);
    mLastViewFragment = mFragment;
}

但我收到此错误，但我无法解决：

Error:(141, 29) java: incompatible types: ir.jaziire.Fragments.ActionbarTabsPager cannot be converted to com.actionbarsherlock.app.SherlockListFragment
Error:(149, 29) java: incompatible types: com.actionbarsherlock.app.SherlockListFragment cannot be converted to com.actionbarsherlock.app.SherlockFragmentActivity

我的问题是：

mFragment = new ActionbarTabsPager();

最佳答案

ActionbarTabsPager正在扩展SherlockFragmentActivity，而不是SherlockFragment。更改

public class ActionbarTabsPager extends SherlockFragmentActivity {

至

public class ActionbarTabsPager extends SherlockFragment {

和

SherlockFragmentActivity mFragment = null;

至

Fragment mFragment = null;
