Enter different values into the EditText widget, and then click the button to see it grab the text and display it on itself, as demonstrated in the screenshot at the start of this tutorial.

Change what the image in the app looks like with different combinations of checked and unchecked checkboxes and hide and show the TextView widget by using the Switch widget above it. The following screenshot displays two combinations of the checkboxes and the switch widget photoshopped together for demonstration purposes:

Tip

Transparency doesn't show very clearly in a print book, so I didn't check that box. Be sure to try this out on an emulator or real device.
