/**       HTML  ，   javadoc          
 * An activity is a single, focused thing that the user can do.  Almost all
 * activities interact with the user, so the Activity class takes care of
 * creating a window for you in which you can place your UI with
 * {@link #setContentView}.  While activities are often presented to the user
 * as full-screen windows, they can also be used in other ways: as floating
 * windows (via a theme with {@link android.R.attr#windowIsFloating} set)
 * or embedded inside of another activity (using {@link ActivityGroup}).
 *
 * There are two methods almost all subclasses of Activity will implement:
 * 
 * 

 *     
 {@link #onCreate} is where you initialize your activity.  Most
 *     importantly, here you will usually call {@link #setContentView(int)}
 *     with a layout resource defining your UI, and using {@link #findViewById}
 *     to retrieve the widgets in that UI that you need to interact with
 *     programmatically.
 * 
 *     
 {@link #onPause} is where you deal with the user leaving your
 *     activity.  Most importantly, any changes made by the user should at this
 *     point be committed (usually to the
 *     {@link android.content.ContentProvider} holding the data).
