由于不推荐使用PreferenceFragment,因此我使用PreferenceFragmentCompat.

更换片段后,我从内容中得到左缩进:

缩进很可能是因为图标而出现,但我不使用它们(默认是没有图标).

    <FrameLayout
        android:id="@+id/fragment_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

class SettingsFragment : PreferenceFragmentCompat() {

companion object {

     * A preference value change listener that updates the preference's summary
     * to reflect its new value.
     */
    private val sBindPreferenceSummaryToValueListener = Preference.OnPreferenceChangeListener { preference, value ->

        val stringValue = value.toString()

        if (preference is ListPreference) …
