我发现了许多动态改变活动主题的方法 但是我使用了一些不能改变主题的图表和图表,因为它们不仅仅是活动。
所以,我需要找到一种动态更改应用主题的方法,这样我的图表主题也会改变!

我想知道是否有人可以解决这个问题。

这是我的代码,适用于每项活动:

public class Utils
{
    private static int sTheme;

    public final static int THEME_DEFAULT = 0;
    public final static int THEME_WHITE = 1;
    public final static int THEME_BLUE = 2;
    public final static int THEME_PINK = 3;

    /**
     * Set the theme of the Activity, and restart it by creating a new Activity
     * of the same type.
     */
    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:
            break;
        case THEME_WHITE:
            activity.setTheme(R.style.Theme_white);
            break;
        case THEME_BLUE:
            Log.i("THM", "blue intered in utils");
            activity.setTheme(R.style.Theme_blue);
            break;
        case THEME_PINK:
            activity.setTheme(R.style.Theme_pink);

            break;
        }
    }
}

我使用此代码更改我的活动主题:

Utils.changeToTheme(G.tabActivity, Utils.THEME_DEFAULT);

您可以将当前主题存储在SharedPreferences中并在应用开始时应用它:

SharedPreferences pref = context.getSharedPreferences("your_pref_name", android.content.Context.MODE_PRIVATE);
String theme = pref.getString("your_pref_key", "your_default_theme");
context.setTheme(theme);

然后,当您更改主题时,您应该重新启动应用程序:

Intent intent = getPackageManager().getLaunchIntentForPackage(getPackageName());
finish();
startActivity(intent);
