如何在android中制作渐变背景 [英] How to make gradient background in android

问题描述

我想创建渐变背景，渐变位于上半部分，下半部分为纯色，如下图所示:

I want to create gradient background where the gradient is in the top half and there's a solid color in the bottom half, like in this image below:

我不能，因为 centerColor 展开以覆盖底部和顶部.

I can't because the centerColor spreads out to cover the bottom and top.

如何制作与第一张图片一样的背景?如何制作不散开的小centerColor?

How can I make a background like the first image? How can I make small centerColor that's not spread out?

这是上面背景按钮的 XML 代码.

This is code in XML of background button above.

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
    <gradient 
        android:startColor="#6586F0"
        android:centerColor="#D6D6D6"
        android:endColor="#4B6CD6"
        android:angle="90"/>
    <corners 
        android:radius="0dp"/>


</shape>

推荐答案

您可以使用 xml 创建这种半渐变"外观 Layer-List 将顶部和底部的带"合并到一个文件中.每个波段都是一个 xml 形状.

You can create this 'half-gradient' look by using an xml Layer-List to combine the top and bottom 'bands' into one file. Each band is an xml shape.
