如何更改自定义启动画面中的背景颜色？

Question

In order to remove the default white splash screen I made a custom theme:

styles.xml

 <style name="AppTheme.SplashTheme">
        <item name="android:windowBackground">@drawable/splash_screen</item>
  </style>

splash_screen.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:opacity="opaque">

<!--<item android:drawable="?colorPrimary" />-->
<item>
    <bitmap
        android:gravity="center"
        android:src="@drawable/wq_logo" />
</item>
</layer-list>

Everything works fine but I want to change the background color of it. Its currently showing a purple color background. I want to make it white. In this app I'm using a Navigation drawer layout.

Change the splash_screen.xml like this

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
         android:opacity="opaque">

<item>
    <shape xmlns:android="http://schemas.android.com/apk/res/android"      
       android:shape="rectangle">
      <solid android:color="@color/grey" />
    </shape>
</item>
<item>
    <bitmap
        android:gravity="center"
        android:src="@drawable/wq_logo" />
</item>

You can add another item to the layer-list . You only have to change the background color to your preferred one.

For my part, this solution did not solve the problem. To fix it I declare the background image of the splash screen like this: (dont use bitmap)

<item android:drawable="@color/colorPrimary" />

<item
    android:drawable="@drawable/ic_launcher"
    android:gravity="center" />
