Simple SwitchPreference example in Android

We can add SwitchPreference to PreferenceScreen in xml like below in android
R.xml.switch_preference.xml 
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <SwitchPreference
        android:key="switch"
        android:summaryOff="Switch off"
        android:summaryOn="Switch on"
        android:title="Switch Preference" />
</PreferenceScreen>

We have to use PreferenceFragment to access this xml like below. SwitchPreference.java 
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceFragment;
import android.preference.PreferenceManager;
import android.support.annotation.Nullable;
import android.widget.Toast;

/**

public class SwitchPreference extends PreferenceFragment {
    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.switch_preference);
    }

    @Override
    public void onResume() {
        super.onResume();
        //You can change preference summary programmatically like following.
        android.preference.SwitchPreference preference = (android.preference.SwitchPreference) findPreference("switch");
        preference.setSummaryOff("Switch off state updated from code");
        preference.setSummaryOn("Switch on state updated from code");

        //You can read preference value anywhere in the app like following. 
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
        boolean isChecked = sharedPreferences.getBoolean("switch", false);
        Toast.makeText(getActivity(), "isChecked : " + isChecked, Toast.LENGTH_LONG).show();
    }
}
