佈局程式碼為

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@drawable/black"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <!--應用樣式1的TextView-->
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        style="@style/DavidStyleText1"
        android:gravity="center_vertical|center_horizontal"
        android:text="應用DavidStyleText1樣式的"/>
    <!--應用樣式2的TextView-->
    <TextView
        style="@style/DavidStyleText2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal|center_vertical"
        android:text="應用於DavidStyleText2樣式的"/>
</LinearLayout>
 

1.LinearLayout線性佈局，從頭到尾，要跟上android:orientation表示橫著還是豎著 2.android:gravity抽象對應重力，"center_vertical|center_horizonta既往豎直中間偏，又往水平中間偏 style中程式碼為
