使用片段在可Swipable选项卡中加载首选项设置

Posted 2021-04-21

我在网上搜索过但没找到任何合适的解决方案。

我正在尝试在Tab Fragments中加载一些首选项设置。

在第一张图片中，当我使用菜单充气器时，我得到那些3个虚线按钮，我不需要那些，我想让菜单加载到我的Tab片段中。

以下是我的代码

setting pref activity.Java

public class SettingsPrefActivity extends AppPreferenceActivity {
private static final String TAG = SettingsPrefActivity.class.getSimpleName();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    // load settings fragment
    getFragmentManager().beginTransaction().replace(android.R.id.content, new MainPreferenceFragment()).commit();
}

public static class MainPreferenceFragment extends PreferenceFragment {
    @Override
    public void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.pref_main);

        // gallery EditText change listener
        bindPreferenceSummaryToValue(findPreference(getString(R.string.key_gallery_name)));

        // notification preference change listener
        bindPreferenceSummaryToValue(findPreference(getString(R.string.key_notifications_new_message_ringtone)));

        // feedback preference click listener
        Preference myPref = findPreference(getString(R.string.key_send_feedback));
        myPref.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
            public boolean onPreferenceClick(Preference preference) {
                sendFeedback(getActivity());
                return true;
            }
        });
    }
}

            PreferenceManager
                    .getDefaultSharedPreferences(preference.getContext())

我是否有可能将main_menu.xml包含到我的setting_layout.xml中？这样它会绑定到我的SettingsActivity.java？如果它可能，那将是伟大的，但我尝试了这种方式，并没有找到适当的方式来包括它。

有人可以指导我如何实现这一目标..

答案

尝试将此添加到您的片段：

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    MenuItem item= menu.findItem(R.id.action_settings);
    item.setVisible(false);
    super.onPrepareOptionsMenu(menu);
    return true;
}
