40.4 Designing the Fragment Layout
The next step is to design the layout of the fragment. Locate the main_fragment.xml file in the Project tool window and double click on it to load it into the layout editor. Once the layout has loaded, select the existing TextView widget and use the Attributes tool window to change the id property to resultText.
Drag a Number (Decimal) view from the palette and position it above the existing TextView. With the view selected in the layout refer to the Attributes tool window and change the id to dollarText.
Drag a Button widget onto the layout so that it is positioned below the TextView, and change the text attribute to read “Convert”. With the button still selected, change the id property to convertButton. At this point, the layout should resemble that illustrated in Figure 40-3 (note that the three views have been constrained using a vertical chain):
