Java 如何从一个活动转到PreferenceFragment？

从属于

活动的主页导航到使用
首选项片段的帐户设置页面时遇到问题

我正试图通过导航抽屉来实现这一点，当点击项目时，应该会显示设置页面。除帐户设置页面外，我的所有其他页面都是
片段
，并且所有页面都正常工作（设置页面除外）。我认为
PreferenceFragment
是从
Fragment
扩展而来的，所以它肯定能工作吗

MainPage.java

@Override
public void onNavigationDrawerItemSelected(int position) {
    // update the main content by replacing fragments
    FragmentManager fragmentManager = getSupportFragmentManager();
    if (position == 0) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, PlaceholderFragment.newInstance(1))
                .commit();

    } else if (position == 1) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, Search.newInstance(2))
                .commit();

    }

    else if (position == 2) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, Favourites.newInstance(3))
                .commit();
    }

    else if (position == 3) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, History.newInstance(4))
                .commit();

    }

    else if (position == 4) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, AccountSettings.newInstance(5))
                .commit();

    }

}

public class AccountSettings extends PreferenceFragment {

    Activity mActivity;

    private static final String ARG_SECTION_NUMBER = "section_number";

    public static AccountSettings newInstance(int sectionNumber) {
        AccountSettings fragment = new AccountSettings();
        Bundle args = new Bundle();
        args.putInt(ARG_SECTION_NUMBER, sectionNumber);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);    //inflating layout
        addPreferencesFromResource(R.xml.settings);
        setHasOptionsMenu(true);
        restoreActionBar();

    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        mActivity = activity;

    }

    public void restoreActionBar() {
        ActionBar actionBar = ((AppCompatActivity)getActivity()).getSupportActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
        actionBar.setDisplayShowTitleEnabled(true);
        actionBar.setTitle("Account Settings");
    }

    public AccountSettings() {

    }
}

AccountSettings.java

@Override
public void onNavigationDrawerItemSelected(int position) {
    // update the main content by replacing fragments
    FragmentManager fragmentManager = getSupportFragmentManager();
    if (position == 0) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, PlaceholderFragment.newInstance(1))
                .commit();

    } else if (position == 1) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, Search.newInstance(2))
                .commit();

    }

    else if (position == 2) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, Favourites.newInstance(3))
                .commit();
    }

    else if (position == 3) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, History.newInstance(4))
                .commit();

    }

    else if (position == 4) {
        fragmentManager.beginTransaction()
                .replace(R.id.container, AccountSettings.newInstance(5))
                .commit();

    }

}

public class AccountSettings extends PreferenceFragment {

    Activity mActivity;

    private static final String ARG_SECTION_NUMBER = "section_number";

    public static AccountSettings newInstance(int sectionNumber) {
        AccountSettings fragment = new AccountSettings();
        Bundle args = new Bundle();
        args.putInt(ARG_SECTION_NUMBER, sectionNumber);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);    //inflating layout
        addPreferencesFromResource(R.xml.settings);
        setHasOptionsMenu(true);
        restoreActionBar();

    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        mActivity = activity;

    }

    public void restoreActionBar() {
        ActionBar actionBar = ((AppCompatActivity)getActivity()).getSupportActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
        actionBar.setDisplayShowTitleEnabled(true);
        actionBar.setTitle("Account Settings");
    }

    public AccountSettings() {

    }
}

在MainPage.java上会出现以下错误：

'replace(int, android.support.v4.app.Fragment)' in 'android.support.v4.app.FragmentTransaction' cannot be applied to '(int, com.example.laptop.whatsfordinner.AccountSettings)'

我尝试将其更改为
片段
，它可以工作，但我想使用
首选片段
，那么如何才能使其工作

当然，我只是遗漏了一些非常明显的东西？
您需要使用
getFragmentManager
作为首选片段。因为它们不扩展Fragment类的支持v4版本
 您需要使用
getFragmentManager
获取PreferenceFragment。因为它们不扩展Fragment类的支持v4版本
 一种选择是使用，这是针对这种情况创建的。请参见此处的示例：一个选项是使用，它是针对这种情况创建的。有关示例，请参见此处：
