Using Android build-in theme

We can apply Android build-in theme on our app. It's a example using Theme.Dialog.



Modify AndroidManifest.xml using android:theme="@android:style/Theme.Dialog".

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.AndroidStyle"
   android:versionCode="1"
   android:versionName="1.0" >

   <uses-sdk android:minSdkVersion="8" />

   <application
       android:icon="@drawable/ic_launcher"
       android:label="@string/app_name"
       android:theme="@android:style/Theme.Dialog" >
       <activity
           android:name=".AndroidStyleActivity"
           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>

Modify main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:orientation="vertical" >

   <TextView
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:text="@string/hello" />
   <TextView
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:text="using Android's Theme.Dialog" />
  
</LinearLayout>
