今天试着做activity半透明的效果,做出来之后才发现想复杂了!很简单的几句就可以实现,不多说了,贴代码!

 

1. res/values/styles.xml

 
<resources>    

<mce:style name="Transparent><!--  

    

<item name="android:windowBackground">@color/transparent_background</item>    

<item name="android:windowNoTitle">true</item>    

<item name="android:windowIsTranslucent">true</item>      

<item name="android:windowAnimationStyle">@+android:style/Animation.Translucent</item>    

--></mce:style><style name="Transparent mce_bogus="1">    

<item name="android:windowBackground">@color/transparent_background</item>    

<item name="android:windowNoTitle">true</item>    

<item name="android:windowIsTranslucent">true</item>      

<item name="android:windowAnimationStyle">@+android:style/Animation.Translucent</item>  </style>    

</resources>  

 

 

 

2. res/values/color.xml

 

<?xml version="1.0" encoding="utf-8"?>    

<resources>    

<color name="transparent_background">#50000000</color>    

</resources>    

 

 

注意:color.xml的#5000000前两位是透明的效果参数从00--99(透明--不怎么透明),后6位是颜色的设置 

 

3. AndroidManifest.xml

 

 
<activity android:name=".TransparentActivity" android:theme="@style/Transparent">    

</activity>  

 

 

 

4.  代码

 

 
public void onCreate(Bundle savedInstanceState) {    

super.onCreate(savedInstanceState);    

setTheme(R.style.Transparent);     

setContentView(R.layout.transparent);    

}
