How to make your activity appear like a dialog box in android?

Hello all..

Here is how you do it.
After creating your activity -> go to AndroidManifest.xml. then add this inside the activity tag.

android:theme=”@android:style/Theme.Dialog”

After that the manifest will look something like this.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.coderzheaven.pack"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@android:style/Theme.Dialog">
        <activity android:name=".ThemeActivityDemo"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

The activity for which you have added this theme will appear as a dialog as shown in the figure.
