使用RelativeLayout這樣的：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical"> 

<me.dm7.barcodescanner.zxing.ZXingScannerView 
    android:id="@+id/zxscan" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    /> 

<ImageView 
    android:id="@+id/btn_flash" 
    android:layout_marginBottom="15dp" 
    android:layout_centerHorizontal="true" 
    android:layout_alignParentBottom="true" 
    android:src="@drawable/flash_100" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" /> 

它的樣子：
