Android offers a sophisticated and powerful componentized model for building your UI, based on the fundamental layout classes: View and ViewGroup.

A partial list of available widgets includes Button, TextView, EditText, ListView, CheckBox, RadioButton, Gallery, Spinner, and the more special-purpose AutoCompleteTextView, ImageSwitcher, and TextSwitcher. Among the layouts available are LinearLayout, FrameLayout, RelativeLayout, and others. For more examples, see Common Layout Objects. List of Sample Apps.
