XML 範例

<?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"

    <TextView
        android:gravity="center"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"

        android:shadowDx="10"
        android:shadowDy="10"
       
        />
   
    <TextView
        android:gravity="center"
