AndroidX BottomAppBar导航图标颜色 [英] AndroidX BottomAppBar navigation icon color

问题描述

我在这样的布局中定义了一个底部栏:

I've defined a bottom bar in a layout like that:

<com.google.android.material.bottomappbar.BottomAppBar
    android:id="@+id/bottomBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    app:navigationIcon="@drawable/ic_menu_black_24dp" />

导航图标是从新的矢量可绘制"向导生成的常规图标.有没有办法对它应用色彩?

The navigation icon is a generic icon generated from the "new vector drawable" wizard. Is there a way to apply a tint to it?

底部栏不是活动操作栏.

The bottom bar is not the activity action bar.

到目前为止我尝试过的事情:

What I've tried so far:

• 应用了具有覆盖的 textColorPrimary 颜色
的主题
• 应用具有覆盖的 controlColorNormal 颜色
的主题

• applied a theme with an overridden textColorPrimary color
• applied a theme with an overridden controlColorNormal color

如果有一种解决方案也适用于通过从XML加载菜单(使用 inflateMenu()或 replaceMenu())提供的图标，那将是完美的./p>

If there's a solution that also works on icons supplied by loading a menu from XML (using inflateMenu() or replaceMenu()), that would be perfect.

推荐答案

导航图标的颜色基于 colorControlNormal 属性.
您可以使用以下方法覆盖它:

The navigation icon color is bases on colorControlNormal attribute.
You can override it using:

<com.google.android.material.bottomappbar.BottomAppBar
    android:theme="@style/ThemeOverlay.BottomAppBar"

具有:

<style name="ThemeOverlay.BottomAppBar">
    <item name="colorControlNormal">@color/....</item>
</style>
