How saving the state of a switch

I am developing a game on Android, I have a background music that stop with a switch and that is in an other activity, that of the parameters. The music is in the main menu.

I would like to know how to save the state of the switch (checked or not checked) by going from the main menu to the parameters

This the code for my switch : 

buttonmusique = (Switch) findViewById(R.id.switchMusique);
   buttonmusique.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

        @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                Log.e("bouton", String.valueOf(buttonmusique.isChecked()));
                // If the music is playing
                if (isChecked) {
                    Intent music = new Intent();
                    music.setClass(Parametres.this, BackgroundMusic.class);
                    startService(music);
                    musicBoolean = true;
                    buttonmusique.setText("Musique On");  //To change the text near to switch
                    Log.d("You are :", "Checked");
                } else {
                    Intent music = new Intent();
                    music.setClass(Parametres.this, BackgroundMusic.class);
                    stopService(music);
                    musicBoolean = false;
                    // Resume the music player
                buttonmusique.setText("Musique OFF");   //To change the text near to switch
                Log.d("You are :", " Not Checked");

            }
        }
    });

Put it in your create method: (+adapt to your situation)

final SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
CheckBox checkbox = (CheckBox) findViewById(R.id.myCheckBox);
checkbox.setChecked(sharedPreferences.getBoolean("mycheckbox", true));

checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                sharedPreferences.edit().putBoolean("mycheckbox", b).apply();
            }
        });

You can save it in SharedPreferences.

SharedPreferences prefs = getActivity().getPreferences(Context.MODE_PRIVATE);

Save sound settings

SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean(getString(R.string.sound_enabled), isChecked);
editor.commit();

To get sound settings use:

boolean soundEnabled = prefs.getBoolean(getString(R.string.sound_enabled), false);

// Set switch state
buttonmusique.setChecked(soundEnabled);

Use shared preferences or a database to store the state of your switch. It is essential that you depend on the lifecycle methods of Activity/fragment.

The following might help you: 

......
.....
@Override
public void onClick(View v) 
{
    if (toggle.isChecked()) 
    {
        SharedPreferences.Editor editor = getSharedPreferences("com.example.xyz", MODE_PRIVATE).edit();
        editor.putBoolean("state_to_save", true);
        editor.commit();
    }
    else
    {
        SharedPreferences.Editor editor = getSharedPreferences("com.example.xyz", MODE_PRIVATE).edit();
        editor.putBoolean("state_to_save", false);
        editor.commit();
    }
}

The final Code: 

@Override
protected void onCreate(Bundle savedInstanceState) 
{ 
 .......
    ......
    SharedPreferences sharedPrefs = getSharedPreferences("com.example.xyle", MODE_PRIVATE);
    toggle.setChecked(sharedPrefs.getBoolean("state_to_save", true));
}

Load status:

boolean switch_status = PreferenceManager.getDefaultSharedPreferences(ctx).getBoolean("switch_status", false);

Save status:

SharedPreferences.Editor sped = PreferenceManager.getDefaultSharedPreferences(ctx).edit();
    sped.putBoolean("switch_status", value);
    sped.commit();
