FATAL EXCEPTION: main & NullPointerException
I've been looking around several hours for a solution. I'm trying to build a BodyMassIndex calculator. I have finished the program (i think) but every time I try to run the app, it crashes on the emulator. On top of that, the layout preview isn't showing up anymore. I'm still trying to learn what all of the error codes in the log mean. I think it's a problem with my layout.xml, but I'm not sure. Any suggestions or ideas would be greatly appreciated!

Remember below about TableLayout.
A layout that arranges its children horizontally. A TableRow should always be used as a child of a TableLayout. If a TableRow's parent is not a TableLayout, the TableRow will behave as an horizontal LinearLayout.
The children of a TableRow do not need to specify the layout_width and layout_height attributes in the XML file. TableRow always enforces those values to be respectively MATCH_PARENT and WRAP_CONTENT.
I used your layout and removed some of the attributes.It is working now. You cna do one thing, try to add the deleted attributes one by one and check the validity using the graphic layout tab.

There is some problem in the layout file. Spans Error and child height of table row. Try using this xml. Just copy paste the same from table row0, It should work.
