代碼如下：
[java]

<LinearLayout 
        android:layout_width="wrap_content" 
        android:layout_height="fill_parent" 
        android:orientation="vertical" 
        android:layout_weight="1" 
        android:padding="20dp" > 

        <LinearLayout  
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:orientation="horizontal"> 
            <LinearLayout  
                android:layout_width="108dp" 
                android:layout_height="108dp" 
                android:orientation="vertical" 
                android:background="#3399ff"> 
                <ImageView  
                    android:layout_width="64dp" 
                    android:layout_height="64dp" 
                    android:src="@drawable/menu_icon__mail" 
                    android:layout_gravity="center"/> 
            </LinearLayout> 

于是乎四處找資料尋求解決的方式，原來(lái)是父類視圖的屬性沒(méi)有設(shè)置的原因，將父類視圖設(shè)置為居中邊可解決，即android:gravity="center"：
[java]

復(fù)制代碼代碼如下:

<LinearLayout 
        android:layout_width="wrap_content" 
        android:layout_height="fill_parent" 
        android:orientation="vertical" 
        android:layout_weight="1" 
        android:padding="20dp" > 

        <LinearLayout  
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:orientation="horizontal"> 
            <LinearLayout  
                android:layout_width="108dp" 
                android:layout_height="108dp" 
                android:orientation="vertical" 
                android:gravity="center" 
                android:background="#3399ff"> 
                <ImageView  
                    android:layout_width="64dp" 
                    android:layout_height="64dp" 
                    android:src="@drawable/menu_icon__mail" 
                    android:layout_gravity="center"/> 
            </LinearLayout>
