问题
I've been assigned to create an activity that displays table of changes made to the app by version. The table has four columns, Id, Type, Description, and Version.
To do this, I placed a TableLayout in a scrollView. Then, I have a template for the TableRows, that are inflated dynamically at Runtime. The column widths should stay static; they can overflow in height but not width.
To achieve this, I tried using the weight & weight: sum property of the column and row container respectively. I have set the layout_width to 0 on both.
The problem is that the columns are expanding outside the screen boundaries. I would post the images but I don't have the authority.
(Landscape looks close but you can see that the outer boundry is still being cut off).
I noticed that in if the weights of the children add to about 45% of the total then the weighting comes close to looking right.
Finally, the views separating the columns have been given a weight of zero, and 1dip width. (I'm not sure if that could be causing a problem).
To me it looks like that weighting is using the width as if it was in landscape mode. Do I have to make two layouts, one for portrait, and one for landscape?
I've added the XML layout for the table row:
<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="@+id/table_row_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<View
android:id="@+id/top_border"
android:layout_width="match_parent"
android:layout_height="1dip"
android:background="#FFFFFF" />
<LinearLayout
android:id="@+id/horizontal_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="4" >
<View
android:id="@+id/view1"
android:layout_width="1dip"
android:layout_height="match_parent"
android:background="#FFFFFF" android:layout_weight="0.01"/>
<TextView
android:id="@+id/txt_id"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:text="Id" android:textSize="10sp" android:layout_weight="0.5"/>
<View
android:id="@+id/view2"
android:layout_width="1dip"
android:layout_height="match_parent"
android:background="#FFFFFF" android:layout_weight="0.01"/>
<TextView
android:id="@+id/txt_type"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:text="Type" android:textSize="10sp" android:layout_weight="1"/>
<View
android:id="@+id/view3"
android:layout_width="1dip"
android:layout_height="match_parent"
android:background="#FFFFFF" android:layout_weight="0.01"/>
<TextView
android:id="@+id/txt_desc"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:text="Description" android:textSize="10sp" android:layout_weight="2"/>
<View
android:id="@+id/view4"
android:layout_width="1dip"
android:layout_height="match_parent"
android:background="#FFFFFF" android:layout_weight="0.01"/>
<TextView
android:id="@+id/txt_version"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:text="Version" android:textSize="10sp" android:layout_weight="0.5"/>
<View
android:id="@+id/view6"
android:layout_width="1dip"
android:layout_height="match_parent"
android:background="#FFFFFF" android:layout_weight="0.01"/>
</LinearLayout>
<View
android:id="@+id/view7"
android:layout_width="match_parent"
android:layout_height="1dip" android:background="#FFFFFF"/>
</LinearLayout>
</TableRow>
The upper and lower view are top and bottom borders.
And here is the layout for the table that its getting added too:
<?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:scrollbarAlwaysDrawVerticalTrack="true">
<ScrollView
android:id="@+id/view_scroll"
android:layout_width="match_parent"
android:layout_height="wrap_content" android:fillViewport="true">
<TableLayout
android:id="@+id/table_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:shrinkColumns="0"
android:stretchColumns="0" >
</TableLayout>
</ScrollView>
</LinearLayout>

Thanks MH.
Sorry for not getting back to you sooner. (I'm new to Android and Stack Overflow...and I didn't realize that you answered my questsion.) I've added the row layout.
<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<View
android:id="@+id/top_border"
android:layout_width="match_parent"
android:layout_height="1dip"
android:background="#FFFFFF" />
<LinearLayout
android:id="@+id/horizontal_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="4" >
<View
