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); }
