如何修复设备的暗模式和精简模式下的图像视图图标颜色变化

How to fix image view icon color changes in dark mode and lite mode of the device

我想在 imageview 中包含图标,但是当打开深色模式时,颜色是深色的,而当打开精简模式时,它显示为白色,我希望两种模式下的颜色都是白色

向量 // 图标

<vector android:height="24dp" android:tint="@color/white"
    android:viewportHeight="24" android:viewportWidth="24"
    android:width="24dp" xmlns:android="http://schemas.android.com/apk/res/android">
    <path android:fillColor="@color/white" android:pathData="M20,11H7.83l5.59,-5.59L12,4l-8,8 8,8 1.41,-1.41L7.83,13H20v-2z"/>
</vector>

ImageView // 作为背景包含的图标

<ImageView
        android:id="@+id/backArrow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:layout_marginStart="10dp"
        android:layout_marginTop="10dp"
        android:background="@drawable/ic_baseline_arrow_back_24"
        android:contentDescription="@string/todo"
        android:elevation="10dp" />

themes.xml // litemod/normal

<resources xmlns:tools="http://schemas.android.com/tools">

好的,我的问题得到了答案,实际上我的应用程序已经有深色元素,当我向图像视图或更多元素添加白色背景时,它在黑暗中变为深灰色 mod我不想要的设备,所以我找到了解决这个问题的方法

步骤 1

删除值中的night/dark theme.xml

步骤 2

在normal/lighttheme.xml中的值改变

<style name="Theme.MyAppNotFinal" parent="Theme.MaterialComponents.DayNight.NoActionBar">

<style name="Theme.MyAppNotFinal" parent="Theme.MaterialComponents.Light.NoActionBar">

步骤 3

在同一个 theme.xml // light/normal 主题中

添加这一行

 <item name="android:forceDarkAllowed" tools:targetApi="q">false</item>

里面的风格

像这样

<style name="Theme.MyAppNotFinal" parent="Theme.MaterialComponents.Light.NoActionBar">
<item name="android:forceDarkAllowed" tools:targetApi="q">false</item>
</style>

这个方法对我有用,如果还有人有问题,请检查下面的问题,它有很多答案希望它对你有用
