The call to getId() will return -1 when you are creating your views programmatically, as you are doing above. You must assign ID's to the objects with the setId() call first.
Note that the documentation for View says that you may specify any ID that you like -- it does not have to be unique within the View's hierarchy. -Nik On Jun 18, 8:31 pm, Jahir <[email protected]> wrote: > Hello, > I am trying to display two TextViews in two separate line.
