[android-developers] Problem in nesting LinearLayout?

[javame_android]

Hi,

I am facing a problem in designing LinearLayout. What I want is the
Textbox at the top and button bar at the bottom. But the top Textbox
just don't appear.

The xml file looks like this :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
        android:layout_width = "fill_parent"
        android:layout_height = "fill_parent"
        android:orientation="vertical"
        android:background = "#ffffff">

        <LinearLayout
           android:id="@+id/button_bar"
           android:layout_width="320dip"
           android:layout_height="50dip"
           android:orientation="horizontal"
           android:gravity = "bottom"
           android:padding="0dip"
           android:background = "#FFFFFF"
           style="@android:style/ButtonBar">

           <Button android:id="@+id/mapbtn"
                   android:layout_width="80dip"
                   android:layout_height="50dip"
                   android:layout_weight="1"
                   android:background = "@drawable/mapbtn"/>

           <Button android:id="@+id/mebtn"
                   android:layout_width="80dip"
                   android:layout_height="50dip"
                   android:layout_weight="1"
                   android:background="@drawable/mebtn"/>

           <Button android:id="@+id/friends"
                   android:layout_width="80dip"
                   android:layout_height="50dip"
                   android:layout_weight="1"
                   android:background="@drawable/friendsbtn"/>

           <Button android:id="@+id/privacy"
                   android:layout_width="80dip"
                   android:layout_height="50dip"
                   android:layout_weight="1"
                   android:background="@drawable/privacybtn"/>
         </LinearLayout>

    <LinearLayout
                        android:id="@+id/searchbox"
                        android:layout_width="320dip"
                        android:layout_height="44dip"
                        android:orientation = "vertical"
                        android:gravity = "top"
                        android:background = "#96A2B5">

                        <EditText
                                android:id = "@+id/searchtxt"
                                android:layout_width = "260dip"
                                android:layout_height = "31dip"
                                android:lines = "1"
                                android:maxLines = "1"
                                android:layout_marginLeft = "5dip"
                                android:layout_marginTop = "8dip" >
                        </EditText>
        </LinearLayout>

</LinearLayout>

I just don't understand what is the issue over here. I think its
something to do with android:orientation parameter, but I don't what
is it.

Can someone here please point out the mistake in this and let me know
the solution for this.?

Hope to get a quick reply.


Regards
Sunil
