嵌入在另一个线性布局中的线性布局

Question

我试图在另一个线性布局中嵌入线性布局。我有地图视图。如果我在mapview之后放置嵌入式布局，它不起作用。如果我把它放在它之前呢？为什么，我该怎么做？

下面给出两个文件：第一个失败。第二个工程？我想要第一个。

<!--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覆盖了整个屏幕，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" --> 

编辑：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <LinearLayout 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:orientation="horizontal" 
     android:id="@+id/thebar" 
     android:layout_alignParentBottom="true"> 

     <CheckBox 
      android:id="@+id/chkShowStreetView" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="@string/strShowStreetView" /> 

     <CheckBox 
      android:id="@+id/chkShowSatelliteView" 
      android:layout_width="wrap_content"
