Android:带有导航抽屉片段的首选项片段 [英] Android: Preference Fragment with a Navigation Drawer's Fragment

问题描述

我有一个已经使用导航抽屉的 Android 应用.我的 MainActivity 扩展了 Fragment Activity 和我的 SettingFragment 扩展了 PreferenceFragment

Hi I have an Android app that already uses a Navigation Drawer. My MainActivity extends Fragment Activity and my SettingFragment extends PreferenceFragment

设置片段:

public class SettingsFragment extends PreferenceFragment {
    public SettingsFragment() {}

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Load the preferences from an XML resource
        addPreferencesFromResource(R.xml.prefs);
    }
}

和我的MainActivity:

PreferenceFragment preferenceFragment = new SettingsFragment();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(android.R.id.content, preferenceFragment); // I'm getting an error here should be Fragment not PreferenceFragment
ft.commit();

我如何提交或转到 SettingsFragment()?

How can I commit or go to the SettingsFragment()?

推荐答案

这对我有用.请记住，此代码适用于 API 级别 11 及更高版本.

This Worked for me. Just keep in mind that this code will work with api leval 11 and higher.

在 Activity 中使用此代码添加 Fragment.

In Activity use this code to add Fragment.

android.app.Fragment infoFragment = new InfoFragment();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.add(android.R.id.content, infoFragment);
ft.commit();

您的 PreferenceFragment 类将如下所示.

And Your PreferenceFragment class will be look like this.

public class InfoFragment extends PreferenceFragment 
{
 /**
  * The fragment argument representing the section number for this
  * fragment.
 */
 private static final String ARG_SECTION_NUMBER = "section_number";

 /**
  * Returns a new instance of this fragment for the given section
  * number.
  */

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

  public InfoFragment() 
  {

  }
}
