Use hierarchyviewer to figure out where your missing widgets are:

http://developer.android.com/guide/developing/tools/hierarchy-viewer.html

Here are some things that are unusual about your XML:

> android"

It is strange that you have the top-level container have a layout_height
of wrap_content, particularly when you later attempt to use a
layout_height of fill_parent for the second of the children. Consider
making layout_height fill_parent here.

TableLayout does not have an android:orientation attribute.

It is unclear why you are using TableLayout here versus a LinearLayout,
since you have a one-row, one-column table.
