private fun setToolbarNavigationIconColor(context: Context, toolbar: Toolbar?, color: Int) {
    val drawableBack = toolbar?.navigationIcon
    drawableBack?.let {
        val drawableWrap = DrawableCompat.wrap(drawableBack).mutate()
        DrawableCompat.setTint(
            drawableWrap, ContextCompat.getColor(context, white)
        )
        toolbar.navigationIcon = drawableWrap
    }
}

使用以下方法:

private Drawable getColoredArrow() {
    Drawable arrowDrawable = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
    Drawable wrapped = DrawableCompat.wrap(arrowDrawable);

    if (arrowDrawable != null && wrapped != null) {
        // This should avoid tinting all the arrows
        arrowDrawable.mutate();
        DrawableCompat.setTint(wrapped, Color.GRAY);
    }

    return wrapped;
}

现在你可以用:

getSupportActionBar().setHomeAsUpIndicator(getColoredArrow());

最简单(也是最好)的方法来改变背面/向上箭头的颜色。最棒的是 没有副作用(不像其他答案)!

用父控件Widget.AppCompat创建一个样式。DrawerArrowToggle，定义颜色和其他你想要的属性。 在app Theme的drawerArrowStyle属性上设置样式。

创建样式:

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <!--        Set that the nav buttons will animate-->
    <item name="spinBars">true</item>
    <!--        Set the color of the up arrow / hamburger button-->
    <item name="color">@color/white</item>
</style>

在App Theme中设置样式:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

    <!--  Change global up-arrow color with no side-effects    -->
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

要更改工具栏的文本颜色(和其他属性)，请创建以下样式:

<style name="ToolbarStyle" parent="Widget.AppCompat.Toolbar">
    <item name="android:textColor">@color/white</item>
    <item name="titleTextColor">@color/white</item>
    <item name="colorControlNormal">@color/white</item> <!-- colorControlNormal is Probably not necessary    -->
</style>

然后在AppTheme上设置该样式:

<!-- Base application theme. -->
<style name="AppTheme.MyProduceApp" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

    <!--  Style the toolbar (mostly the color of the text) -->
    <item name="toolbarStyle">@style/ToolbarStyle</item>
    <!--  Change color of up-arrow    -->
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

需要添加一个属性到您的工具栏主题-

<style name="toolbar_theme" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="colorControlNormal">@color/arrow_color</item>
</style>

将这个toolbar_theme应用到工具栏。

OR

您可以直接应用到您的主题-

<style name="CustomTheme" parent="Theme.AppCompat.Light.NoActionBar">
  <item name="colorControlNormal">@color/arrow_color</item> 
  //your code ....
</style>

解决方法很简单

只需将以下一行放入名为AppTheme的样式中

<item name="colorControlNormal">@color/white</item>

现在您的整个xml代码将如下所示(默认样式)。

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

        <item name="colorPrimary">#0F0F0F</item>
        <item name="android:statusBarColor">#EEEEF0</item>
        <item name="android:windowLightStatusBar">true</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowActivityTransitions">true</item>

        <item name="colorControlNormal">@color/white</item>
</style>

我找到了一个解决办法。在“actionBarWidgetTheme”中设置“colorControlNormal”来改变homeAsUpIndicator的颜色。从上面修改岩壁虎的答案如下:

<style name="MyTheme" parent="Theme.AppCompat.Light">        
    <item name="actionBarTheme">@style/MyApp.ActionBarTheme</item>
    <item name="actionBarStyle">@style/MyApp.ActionBar</item>
    <!-- color for widget theming, eg EditText. Doesn't effect ActionBar. -->
    <item name="colorControlNormal">@color/my_awesome_color</item>
    <!-- The animated arrow style -->
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
    <!-- The style for the widgets on the ActionBar. -->
    <item name="actionBarWidgetTheme">@style/WidgetStyle</item>
</style>

<style name="WidgetStyle" parent="style/ThemeOverlay.AppCompat.Light">
    <item name="colorControlNormal">@color/my_awesome_color</item>
</style>
