以编程方式更改工具栏中的菜单图标颜色 [英] Programmatically change menu icon color in Toolbar

问题描述

我已经开发了一个应用程序，用户可以在其中更改主题.我有一个导航视图，工具栏中的菜单图标是黑色的.

I've developed an App, where the user can change the theme. I have a navigation view, with a menu icon in Toolbar that is black.

我想更改该图标，使其为白色(黑色主题).我尝试了这段代码，但它仍然是黑色的:

I would like to change that icon, to have it white (on a black theme). I tried this code but it remained black:

myToolbar.setTitleTextColor(Color.WHITE);
ab.setHomeAsUpIndicator(R.mipmap.ic_menu_white_24dp); //ab=ActionBar
ab.setDisplayHomeAsUpEnabled(true);

标题变为白色，但图标不变.

The title becomes White, but the icon doesn't change.

推荐答案

1.添加带有您喜欢的颜色ab.setHomeAsUpIndicator(R.drawable.ic_menu_white_new);

1.Add a completely new icon with your favorite color ab.setHomeAsUpIndicator(R.drawable.ic_menu_white_new);

2.使用它着色

    Drawable drawable = ResourcesCompat.getDrawable(getResources(), R.drawable.ic_menu, null);
    drawable = DrawableCompat.wrap(drawable);
    DrawableCompat.setTint(drawable, Color.WHITE);
    ab.setHomeAsUpIndicator(drawable);
