Как реализовать тему на нескольких действиях, используя Utils. java?

0 голосов
/ 28 марта 2020

Я пытался реализовать стиль темы для нескольких действий с помощью Utils. java и я создал другое действие с основным действием, которое называется темами, поскольку я могу поместить в него кнопки для управления всей темой приложения с помощью кнопок my Utils. java 

import android.app.Activity;
import android.content.Intent;

public class Utils {

    private static int sTheme;
    public final static int THEME_DEFAULT = 0;
    public final static int THEME_DARK = 1;
    public final static int THEME_GREEN = 2;
    public final static int THEME_YELLOW = 3;
    public final static int THEME_PINK = 4;
    public final static int THEME_RED = 5;
    public final static int THEME_GREY = 6;

    public static void changeToTheme(Activity activity, int theme)
    {
        sTheme = theme;
        activity.finish();
        activity.startActivity(new Intent(activity, activity.getClass()));
    }
    /** Set the theme of the activity, according to the configuration. */
    public static void onActivityCreateSetTheme(Activity activity)
    {
        switch (sTheme)
        {
            default:
            case THEME_DEFAULT:
                activity.setTheme(R.style.AppTheme);
                break;
            case THEME_DARK:
                activity.setTheme(R.style.darktheme);
                break;
            case THEME_GREEN:
                activity.setTheme(R.style.theme1);
                break;
            case THEME_YELLOW:
                activity.setTheme(R.style.theme2);
                break;
            case THEME_PINK:
                activity.setTheme(R.style.theme3);
                break;
            case THEME_RED:
                activity.setTheme(R.style.theme4);
                break;
            case THEME_GREY:
                activity.setTheme(R.style.theme5);
                break;
        }
    }
}
