The United States acquired all of Florida in the Adams-Onis Treaty because it agreed to give up it's claims on Texas.

The border was set beyond the Sabine River and Arkansas to the 42 North parallel. As a result, Spain renounced its possessions beyond that latitude, including the territory of Oregon. It also ceded definitively Florida, Louisiana and the navigation by the Mississippi river. The Spanish Crown remained the sole sovereign of Texas, territory that the United States claimed as part of Louisiana, which was purchased from the French in 1803.
