java - 更改主题导致双操作栏故障

Question

因此，在我的应用程序中，我创建了一种让用户将主题设置为深色或浅色的方法。我将其实现到每个 Activity 中，但现在如果主题是深色的，则 Activity 有 2 个操作栏。如果我将其保留为浅色主题，则仅显示一个操作栏。这对我来说没有任何意义。非常感谢所有帮助。谢谢。

以下是 Activity 图片:

这是 MainActivity 的代码:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        settings = getSharedPreferences(PREFS_NAME, 0);
        checkDark(settings.getBoolean("darkMode", false));
        super.onCreate(savedInstanceState);
        managerHelper = new ManagerDatabaseAdapter(this);
        setContentView(R.layout.activity_main);
        adapter = new RVAdapter(this, getData());
        RV = (RecyclerView) findViewById(R.id.mainV);
        layoutManager = new LinearLayoutManager(this);
        RV.setLayoutManager(layoutManager);
        RV.setAdapter(adapter);
        adapter.setClickListener(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        //  getMenuInflater().inflate(R.menu.menu_main, li)
        return true;
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK && exitD) {
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Confirm exit")
                    .setPositiveButton("EXIT", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            finish();
                        }
                    })
                    .setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.dismiss();
                        }
                    }).show();
        }
        return super.onKeyDown(keyCode, event);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        switch (id) {
            case R.id.action_settings:
                Intent intent = new Intent(this, SettingsActivity.class);
                intent.putExtra(EXTRA_MESSAGE, true);
                startActivity(intent);
                overridePendingTransition(R.anim.abc_popup_enter, R.anim.abc_fade_out);
                return true;
            case R.id.action_surveyList:
                Intent survey = new Intent(this, GetSurvey.class);
                survey.putExtra(EXTRA_MESSAGE, true);
                startActivity(survey);
                overridePendingTransition(R.anim.abc_popup_enter, R.anim.abc_fade_out);
                return true;
        }
        return super.onOptionsItemSelected(item);
    }

    private void checkDark(boolean isChecked) {
        if (isChecked)
            setTheme(R.style.Dark);
        else
            setTheme(R.style.AppTheme);
    }
}

这是 styles.xml:

不确定这是否是问题的原因，但只是需要注意一下。您的 AppTheme 的父级来自 AppCompat，但您的深色主题正在使用内置的 Material 主题。
