Android 使用 ShelockFragment 而不是 Fragment

Question

我正在使用下面的代码在 Fragment 之间切换，没有任何问题:

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，为了进行此更改，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下面的代码以在 SherlockFragment 之间使用和切换:

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;
}

但我收到这个错误，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();

Answer 1

ActionbarTabsPager 正在扩展 SherlockFragmentActivity，而不是 SherlockFragment。变化

public class ActionbarTabsPager extends SherlockFragmentActivity {

到

public class ActionbarTabsPager extends SherlockFragment {

和

SherlockFragmentActivity mFragment = null;

到

Fragment mFragment = null;
