support RTL languages

by default android puts the gravity for the RTL languages to the right
but when the layout_width="wrap_content" it set the gravity to the right but it'll align the text view to the left of the parent by default 
  
by making the layout_width="fill_parent" android will be able to set the gravity to the right and align the text view to left and our text will get to the right and everyone is happy

**this will not affect the LTR lang and it's tested on ''7, ''5, ''4, inches screens
