Typo and grammatical errors

[RealWorldEdits376W]

In the first paragraph, below the first picture diagram, the line is written as, " Both view are external layout to allow a maximum of customization." This line has some errors.
The correct line could be, " Both views have an external layout to allow maximum customization.

In the usage section, in the ExpandableLayout subheading, the line is written as, "You also need to other layouts for header and content:"
The corrected line could be written as, " You also need other layouts for header and content:"

Thank you.
