Made a nested horizontal linearlayout to move the button
added mylist.xml, which is passed to the listview adapter, in order to be able to change the size of received and sent texts in the listview
Fully commented MainActivity. I think it explains it pretty well.
Merge remote-tracking branch 'origin/LimTextTest' into LimTextTest
