[Android] 안드로이드에서 투명한 Activity를 만드려면 어떻게 해야 하나요?

Q 안드로이드에서 투명한 Activity를 만드려면 어떻게 해야 하나요? 다른 액티비티 위에 떠 있게 만들고 싶습니다.

(질문자: UMAR)

A  res/values/styles.xml파일에 아래 코드 중 <style> ... </style> 부분을 추가하세요.

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="Theme.Transparent" parent="android:Theme">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">false</item>
  </style>
</resources>

위 코드에서, android:color/transparent 부분은 최근 버전 안드로이드에서 이용할 수 있습니다. 만약 안된다면, res/values/color.xml에 #00000000 을 transparent 라는 이름으로 생성한 뒤, 색상 값으로 @color/transparent 를 설정하면 됩니다.

그 다음 AndroidManifest.xml 에서 원하는 액티비티를 선택하고, theme를 설정해 주면 됩니다.

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

Add the following style In your res/values/styles.xml file (if you don’t have one, create it.) Here’s a complete file: <?xml version="1.0" encoding="utf-8"?> <resources> <style name="Theme.Transparent" parent="android:Theme"> <item name="android:windowIsTranslucent">true</item> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowContentOverlay">@null</item> <item name="android:windowNoTitle">true</item> <item name="android:windowIsFloating">true</item> <item name="android:backgroundDimEnabled">false</item> </style> </resources> (the value @color/transparent is the color value #00000000 which I put in res/values/color.xmlfile. You can also use @android:color/transparent in later Android versions) Then apply the style to your activity, for example: <activity android:name=".SampleActivity" android:theme="@style/Theme.Transparent"> ... </activity> shareeditflag edited Feb 10 '13 at 12:55 lambda 1,027620 answered Apr 23 '10 at 17:37 gnobal 10.3k41931
