添加阴影按钮的android [英] Add shadow to button in android

问题描述

我想在图像按钮添加某种影子上点击。是否可能，如何。

I'm trying to add some kind of shadow over image button on click. Is it possible and how.

所以我有按钮，我希望当我点击它，它看起来会推。因此，我创建新的XML这样的：

So i have button and i wished it would look pushed when i click it. So i created new xml like that:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:state_pressed="true"
    android:state_enabled="true"
    android:drawable="@color/btn_pushed" 
     />
<item
    android:drawable="@drawable/btn" />
</selector>

确定它工作正常，但我有像50按钮和我必须做出新的图像为他们所有。这是一个很大的工作，是有可能只是添加一些阴影了呢？或东西，这样它看起来推？

Ok it works fine, but i have like 50 buttons and i have to make new image for all of them. That's a lot of work, is it possible to just add some kind of shadow over it? Or something so that it will look pushed?
