Step 1: Add dependencies First of all, to use the AndroidX Preference framework, we need to add the following dependencies to the project's Build.gradle file: dependencies { implementation 'androidx.preference:preference:1.1.1' } Step 2: Create preference for setting resource files Next, we need to create a preferred resource file to define the user preference settings interface.Create a preference.xml file in the res/xml directory, and define the layout and content of the preference settings. <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <Preferencetegory android: Title = "General Settings"> <CheckBoxPreference android:key="notification_enabled" Android: Title = "Receive Notice" Android: Summary = "Enable /Disable Application Notification" /> <EditTextPreference android:key="username" Android: Title = "Username" Android: Summary = "Set your username" /> </PreferenceCategory> <PrefaceCategory android: Title = "Other Settings"> <ListPreference android:key="theme" Android: Title = "Theme" Android: Summary = "Select the theme of the application" android:entries="@array/theme_labels" android:entryValues="@array/theme_values" android:defaultValue="light" /> </PreferenceCategory> </PreferenceScreen> Step 3: Create PreferenceFragment Next, we need to create a PreferenceFragment to load and display the preference for setting resource files.Create a new class in your activities or fragments and inherit from the PreferenceFragmentCompat class. import android.os.Bundle; import androidx.preference.PreferenceFragmentCompat; public class SettingsFragment extends PreferenceFragmentCompat { @Override public void onCreatePreferences(Bundle savedInstanceState, String rootKey) { setPreferencesFromResource(R.xml.preference, rootKey); } } Step 4: Display preferenceFragment in the event The last step is to add PreferenceFragment to your activities and display the preference settings interface. import android.os.Bundle; import androidx.appcompat.app.AppCompatActivity; public class SettingsActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_settings); getSupportFragmentManager() .beginTransaction() .replace(R.id.settings_container, new SettingsFragment()) .commit(); } } You can then use the above steps to create a user preference setting interface.When the setting activity is called for the first time, the user's configuration option will be displayed.Users can change the preference settings according to their actual needs, which will take effect in the application.
