Let's take a whirlwind tour of some of the previously unexplored items from the palette, and then we can drag a bunch of them onto a layout and see some of the methods they have that might be useful. We can then implement a mini project to put them all to use.
We have already explored Button
and TextView
in the last chapter. Let's take a closer look at a few more widgets.
The EditText
widget does what its name suggests. If we make EditText
available to our users, they will indeed be able to edit the text in it. We saw this in Chapter 5 Real-World Layouts, when we were designing a sign-up form. What we didn't see was how to capture the information from within it or where we would put this text-capturing code.
The next block of code assumes that we have declared an object of the EditText
type and used it to get a reference to EditText
in our XML layout. We might write code like the following for a button click, perhaps a submit button for a form, but it could also...
