Android有趣的全透明效果--Activity及Dialog的全透明
1.Activity全透明
同学zzm给了这个有趣的代码，现在公布出来。
先在res/values下建colors.xml文件，写入：
<? xml version = "1.0" encoding = "UTF-8" ?> < resources > < color name = "transparent" > #9000 </ color > </ resources >
<?xml version="1.0" encoding="utf-8"?> <resources> <style name="Transparent"> <item name="android:windowBackground">@color/transparent</item> <item name="android:windowIsTranslucent">true</item> <item name="android:windowAnimationStyle">@+android:style/Animation.Translucent</item> </style> </resources>
<?xml version="1.0" encoding="UTF-8"?> <resources> <style name="TANCStyle" parent="@android:style/Theme.Dialog"> <!-- 更换背景图片实现全透明 --> <item name="android:windowBackground">@drawable/panel_background_sodino1</item> <!-- 屏幕背景不变暗 --> <item name="android:backgroundDimEnabled">false</item> <!-- 更改对话框标题栏 --> <item name="android:windowTitleStyle">@style/TitleStyle</item> </style> <style name="TitleStyle" parent="@android:style/DialogWindowTitle"> <item name="android:textAppearance">@style/TitleText</item> </style> <style name="TitleText" parent="@android:style/TextAppearance.DialogWindowTitle"> <!-- 设置Dialog标题栏文字颜色。 --> <item name="android:textColor">#000</item> </style> </resources>
