夜间模式导航抽屉Android Studio

Question

我在将所有活动都设为夜间模式时遇到了问题，即使从该平台上我也尝试了很多解决方案。但是我似乎并没有安静地得到答案。有些零件进入夜间模式，而其他零件则没有。这是我的代码块，这是图片

public class MainActivity extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
         Shared_Preferences sharedPref;
        sharedPref = new Shared_Preferences(this);

        if (sharedPref.loadNightModeState()) {
            setTheme(R.style.darktheme);
            //restartApp();
            //getSupportActionBar().setBackgroundDrawable(getDrawable(R.drawable.actionbar));
            //actionBarDrawerToggle.getDrawerArrowDrawable().setColor(getResources().getColor(R.color.BackgroundLight));
        } else setTheme(R.style.AppTheme);
        //restartApp();

        setContentView(R.layout.activity_main);



        super.onCreate(savedInstanceState);
