推荐答案
下载窗口,你在你的屏幕截图实际上是一个活动
使用 @android:款式/ Theme.Holo.Dialog
主题,这使得它看起来像一个对话框。为了达到相同的外观的下载窗口,你的活动
只需要使用相同的主题。
The downloads window that you have in your screenshot is actually an Activity
using the @android:style/Theme.Holo.Dialog
theme which makes it look like a dialog. To achieve the same look as the downloads window, your Activity
need only use the same theme.
您可以设置这个主题在你的清单如下所示:
You can set this theme in your manifest like so:
<activity android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@android:style/Theme.Holo.Dialog" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
示例执行不包括字符串,可绘制的资源。
