My Android Advanced tour------> How do I turn activity into a translucent dialog box? There are two aspects to consider: dialog box and translucent.

You can set activity as a dialog style by specifying the Theme.dialog theme when you define the activity.

You can change the background image of an activity by modifying the Android:windowbackground property value of the Theme.dialog theme. If the background image uses a translucent image, the activity becomes a translucent dialog box. In order to modify the Android:windowbackground property, you can define a new theme that inherits from the Theme.dialog code as follows:

Create two XML files under Res/values, one for theme style resources Dialog_styles.xml,

One for the color resource dialog_colors.xml.

Dialog_styles.xml, themed style named Dialog_translucent

<?xml version= "1.0" encoding= "Utf-8"?><resources>    <style name= "dialog_translucent" parent= "@ Android:style/theme.dialog ">        <item name=" Android:windowbackground "> @color/translucent_background </item>        <item name= "android:windowistranslucent" >true</item>        <item name= "Android: Windownotitle ">true</item>        <item name=" Android:windowanimationstyle "> @android: style/ Animation.translucent</item<span style= "White-space:pre" ></span>>    </style></ Resources>

Dialog_colors.xml

<?xml version= "1.0" encoding= "Utf-8"?><resources> <color    name = "Translucent_background" ># 00000000</color></resources>

Specify a custom theme for the activity in Androidmanifest.xml,Android:theme= "@style/dialog_translucent"

The code is as follows:

       <activity            android:name= ". Dialogactivity "            android:configchanges=" orientation|keyboardhidden|screensize "            android:label=" @string/ App_name "            android:theme=" @style/dialog_translucent "><!--reference a custom theme-->>            <intent-filter>                <action android:name= "Android.intent.action.MAIN"/>                <category android:name= " Android.intent.category.LAUNCHER "/>            </intent-filter>        </activity>
