Android - Can't find handle to LinearLayout

I have the following XML:

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

    second digit denotes hour of day (0 midnight...23 11pm) -->

</TableLayout>

In the code I am trying to get a handle to one of the inner LinearLayouts but none of them appear under

findViewById(R.id.    

etc...

All the other elements appear like row9, row10, etc.

Thanks!

it must start with a character

android:id="@+id/Z123" is valid

android:id="@+id/13" is not valid and u can't reference it in your code

since the auto generate class R can't create a variable start with a number it's invalid in java

You can assign a personalized ID without viewing the xml to any LinearLayout, just do it in the graphic mode: Right click in the object tree view, and use the context menu ASSIGN ID.
