问题描述
我尝试使用GradientDrawable为某些背景和按钮设置渐变.遗憾的是，文档并不是很详细.
I try to use the GradientDrawable to set a gradient to some backgrounds and buttons.Sadly the documentation is not very detailed.
配置渐变的主要属性是什么?我了解start和endcolor，但其他一些属性可能需要一些解释.
What are the main attributes to configure the gradient? I understand start and endcolor but some of the other attributes could need some explanation.
此刻，我使用图像作为按钮的背景，但是用XML定义的可绘制对象会更好.
At the moment I used images as the background for the buttons but a drawable defined in XML would be much nicer.
我尝试看起来像这样(渐变非常浅):替代文字http://janusz.de/~janusz/RedButton.png
I try to get a look like this (It is a very light gradient): alt text http://janusz.de/~janusz/RedButton.png
推荐答案
使用此xml作为imageview的背景.
use this xml as background to the imageview.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient android:angle="90" android:startColor="#7c0000" android:endColor="#A71C1C"/>
</shape>
就这样.
