My Android Advanced tour------> How do I turn activity into a translucent dialog box?

My Android Advanced tour------> How do I turn activity into a translucent dialog box? Can be considered from two aspects: dialog box and translucent.

Specifying the Theme.dialog theme when you define an activity enables you to set activity as a dialog style.

You can change the background image of an activity by altering the Android:windowbackground property value of the Theme.dialog theme.

Assuming the background image uses a translucent image, the activity becomes a translucent dialog box. In order to change the Android:windowbackground property, it is possible to define a new theme that inherits from the Theme.dialog code, such as the following:

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 the topic you define for 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 your own defined theme-->>            <intent-filter >                <action android:name= "Android.intent.action.MAIN"/>                <category android:name= " Android.intent.category.LAUNCHER "/>            </intent-filter>        </activity>
