Place Preference Screen Inside Fragment


i want to know if there is any chance i could place my PreferenceScreen xml inside a ConstraintLayout fragment. I want my PreferenceScreen below the "Settings" text

enter image description here

Here is my Fragment xml code:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/shape_fragment_background"
    tools:context=".ui.fragments.SettingsFragment">

    <TextView
        android:id="@+id/tv_header"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        android:fontFamily="@font/montserrat"
        android:gravity="center"
        android:text="@string/settings"
        android:textSize="24sp"
        android:textStyle="bold"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

And here is my PreferenceScreen code:

<androidx.preference.PreferenceScreen xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <PreferenceCategory app:title="@string/settings">

        <Preference
            app:title="@string/language"
            app:summary="@string/language_summary"
            app:icon="@drawable/ic_baseline_language_24">
            <intent android:action="android.settings.LOCALE_SETTINGS" />
        </Preference>

        <SwitchPreferenceCompat
            app:title="@string/reminder"
            app:summaryOn="@string/reminder_summary_on"
            app:summaryOff="@string/reminder_summary_off"
            app:icon="@drawable/ic_baseline_notifications_24"
            app:key="@string/reminder"/>

    </PreferenceCategory>

    <PreferenceCategory android:title="@string/info">

        <Preference
            app:title="@string/about"
            app:icon="@drawable/ic_baseline_info_24" />

    </PreferenceCategory>

</androidx.preference.PreferenceScreen>

Thanks for the help.


Solution

  • Make a container fragment that holds the preference xml.

    class FragmentContainerSettings : Fragment() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        requireActivity().supportFragmentManager
            .beginTransaction()
            .replace(
                R.id.settings,
                SettingsFragment()
            )
            .commit()
    }
    
    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        val view = inflater.inflate(R.layout.fragment_container_settings, container, false)
    
        return view
        }
    
    
    }
    

    For the PrefereneceScreen settings xml

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

    Layout xml of FragmentContainerSettings. I used LinearLayout here, but you can replace it with ConstraintLayout if you want. Basically when you navigate to FragmentContainerSettings with navController.navigate(R.id.fragmentContainerSettings) it will create the text view and replace the FrameLayout with the PreferenceScreen xml

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        tools:context=".ui.settings.FragmentContainerSettings"
        >
    
        <TextView
        android:id="@+id/tv_header"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        android:fontFamily="@font/montserrat"
        android:gravity="center"
        android:text="@string/settings"
        android:textSize="24sp"
        android:textStyle="bold"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
    
        <FrameLayout
        android:id="@+id/settings"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
    </LinearLayout>
