Question

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片段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

        // 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));

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，这将是伟大的，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个目标..

尝试将此添加到您的片段中：

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

使用片段在可Swipable选项卡中加载首选项设置
