java - 在 PreferenceFragment 中使用 getFragmentSupport Manager

Question

我发现我想在 PreferenceFragment 扩展类中使用这个库，我的问题是 getSupportFragmentManager 无法解决。我的问题是当 fragment 扩展 PreferenceFragment 时如何显示 fragment

我尝试更改为 getFragmentManager 但不起作用

public class PreferencesFragment extends PreferenceFragment {

 final Preference currencyPreference = findPreference(getResources().getString(R.string.setting_category_currency_key));
        currencyPreference.setOnPreferenceClickListener(preference -> {
            //selectCurrencyDialog = new SelectCurrencyFragment();
            //selectCurrencyDialog.show(((SettingsActivity) getActivity()).getSupportFragmentManager(), "SelectCurrency");

            CurrencyPicker picker = CurrencyPicker.newInstance("Select Currency");  // dialog title
            picker.setListener((name, code, symbol, flagDrawableResID) -> {
                // Implement your code here
            });
            picker.show(getSupportFragmentManager(), "CURRENCY_PICKER");

            return false;
        });

}

错误在这一行

getSupportFragmentManager()

picker.show(getSupportFragmentManager(), "CURRENCY_PICKER");

Answer 1

使用 getChildFragmentManager() 而不是 getSupportFragmentManager()
