嵌入在另一個線性佈局中的線性佈局

Question

我試圖在另一個線性佈局中嵌入線性佈局。我有地圖視圖。如果我在mapview之後放置嵌入式佈局，它不起作用。如果我把它放在它之前呢？爲什麼，我該怎麼做？

下面給出兩個文件：第一個失敗。第二個工程？我想要第一個。

<!--two files. 

The first file does not work. The Check Boxes in an embeded linear layout is below the mapview. It only shows map view. 

The second file works. The Check Boxes in an embeded linear layout is ABOVE the mapview.-->

你MapView覆蓋了整個屏幕，android:layout_height="fill_parent"：

<com.google.android.maps.MapView 
     android:id="@+id/mapWhenImClose"  
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:clickable="true" 
     android:apiKey="0MbR34udiEJdnkplC1F7rK4ZxbSFzdRagCruFDA"/> 
     <!-- had this line but it said depreciated   
     android:enabled="true" -->
