App->activity->custom Dialog Example using Activity to implement a custom dialog box

The class customdialogactivity itself is nothing special. The key point is its definition in Androidmanifest.xml:

        <activity android:name= ". App. Customdialogactivity "                android:label=" @string/activity_custom_dialog "                Android:theme = "@style/theme.customdialog">            <intent-filter>                <action android:name= " Android.intent.action.MAIN "/>                <category android:name=" Android.intent.category.SAMPLE_CODE "/>            </intent-filter>        </activity>

Customdialogactivity uses a custom Customdialog style (Theme).

Android apps can use a custom interface style (Theme), Theme as a set of related style definitions that can be applied to an activity or to an entire application. One advantage of using theme is that you can define a unified interface style (uniform background color, font, and so on) for the entire application.

Defining Theme and defining a style, it must be defined in the/res/values subdirectory, where the root element is named resources, the difference between Theme and style is Theme applied to activity and application and The style is applied to a single view. The method of definition is consistent.

The style definition supports inheritance, which can be based on a system-defined style or a previously defined style when defining a new style:

such as the Theme.customdialog definition is based on the Android dialog style (parent) and only modified Windowsbackground properties, using a brown background.

     for a custom dialog appearance.  Here we use an ugly         --    <style name= "Theme.customdialog" parent= "Android:style/theme.dialog" >        <item name= "Android:windowbackground" > @drawable/filled_box</item>    </style>

The background uses shape,filled_box.xml as follows:

<shape xmlns:android= "Http://schemas.android.com/apk/res/android" >    <solid android:color= "#f0600000" />    <stroke android:width= "3DP" android:color= "#ffff8080"/>    <corners android:radius= "3DP"/>    <padding android:left= "10DP" android:top= "10DP"        android:right= "10DP" android:bottom= "10DP"/ ></shape>
