推荐答案

我找到了解决方案，但我希望有更好的方法. 这是最终代码:

I found solution, but I expected better way. Here is final code:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="rectangle" >

        <gradient
            android:endColor="#000004"
            android:gradientRadius="1000"
            android:startColor="#1f3371"
            android:type="radial" >
        </gradient>
    </shape>
</item>
<item>
    <bitmap xmlns:android="http://schemas.android.com/apk/res/android"
        android:src="@drawable/texture_5"
        android:tileMode="repeat" />
</item>
<item android:drawable="@drawable/logo"
    android:bottom="214dp"
    android:top="214dp"
    android:left="100dp"
    android:right="100dp"
    android:gravity="center"
    android:tileMode="repeat"
    >
</item>
</layer-list>

至少它可以在xxhdpi和xhdpi上正常工作.

At least it works at xxhdpi and xhdpi without distortion.
