Question

某些活动中的标题和后退箭头显示为白色，部分显示为黑色。我在Stackoverflow中阅读并应用了所有解决方案，但没有一个能够工作在一些活动中代码工作正常，但其中一些没有！

我的风格：

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowBackground">@drawable/launch_screen</item>

</style>

<style name="NormalTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar"/>

这不起作用：

    <?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:app="http://schemas.android.com/apk/res-auto"

在这项工作中：

<?xml version="1.0" encoding="utf-8"?>

            android:background="?attr/colorPrimary"

    </android.support.design.widget.AppBarLayout>

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:divider="@null"/>

</LinearLayout>

Answer 1

要使工具栏的“后退”箭头和溢出图标变亮，同时保持以灯光为主题的弹出菜单：

在您的style.xml文件中添加工具栏样式：

<style name="AppTheme.Toolbar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="popupTheme">@style/ThemeOverlay.AppCompat.Light</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

将新样式设置为工具栏布局：

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/actionBarSize"
    style="@style/AppTheme.Toolbar"/> <!-- Added style -->

这将为您的工具栏提供深色主题（白色）箭头和溢出图标，但会使弹出菜单保持亮起。

这非常有效，并具有使您的应用更易于主题化的附加好处。

Answer 2

我遇到了这个问题，我只是尝试将自己的drawable设置为这样的后退按钮：

final Drawable your_drawable = getResources().getDrawable(R.drawable.back_arrow);
upArrow.setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(your_drawable);

Actionbar中后退箭头的颜色不会更改
