我试图使用setTheme函数,它基本上根据一些数据库值设置主题,但问题是,一旦我更新了要设置主题的数据库,我需要完成()要实现的主题设置的活动.代码是 -

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        settingsDBAdapter = new SettingsDBAdapter(this);
        settingsDBAdapter.open();

        setSettingsTheme();  <<------THIS LINE WILL SET THEME
        setContentView(R.layout.layout_task_manager);

        quickAddButton = (Button) findViewById(R.id.QuickAddButtonId);

public void setSettingsTheme(){
        String currentTheme = settingsDBAdapter.fetchThemeSettings("theme");
        Log.i(TAG,"settingsDBAdapter + currentTheme-->" + settingsDBAdapter + currentTheme);
        //setTheme(R.style.HoloTheme);
        if(currentTheme.trim().equalsIgnoreCase("holo")){
            Log.i(TAG, "in holo<<<<<<<<");
            setTheme(R.style.HoloTheme);
        }else if(currentTheme.trim().equalsIgnoreCase("hololight")){
            Log.i(TAG, "in hololight<<<<<<<");
            setTheme(R.style.HoloLightTheme);
        }else{
            Log.i(TAG, "iin …
