如何在AndroidX首选项库中使用自定义SharedPreferences名称？

implementation 'androidx.preference:preference-ktx:1.1.1'

class MySettingsFragment : PreferenceFragmentCompat() {
    override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {
        setPreferencesFromResource(R.xml.preferences, rootKey)
    }
}

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory android:title="General">
        <EditTextPreference
            android:key="custom_preference"
            android:title="Custom Preference"
            android:summary="This is a custom preference"
            android:defaultValue="Default value"
            android:dialogTitle="Enter a value"
            android:dialogMessage="Please enter a value for the custom preference" />
    </PreferenceCategory>
</PreferenceScreen>

supportFragmentManager.beginTransaction()
    .replace(R.id.settings_container, MySettingsFragment())
    .commit()

val sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context)
val customPreferenceValue = sharedPreferences.getString("custom_preference", "Default value")
