Implementation of Android drawer (s0000ingdrawer)

MainActivity is as follows:

Package c. c; import android. app. activity; import android. OS. bundle; import android. widget. slidingDrawer; import android. widget. slidingDrawer. onDrawerCloseListener; import android. widget. slidingDrawer. onDrawerOpenListener; import android. widget. slidingDrawer. onDrawerScrollListener;/*** Requirement Description: * implement a simple drawer Demo * Note: * 1 open the drawer icon, the displayed interface is displayed in <SlidingDrawer/> * 2 in <SlidingDrawer/> * use: android: handle = "@ + id/handle_layout" * used to specify the drawer handle *: android: content = "@ + id/content_layout" * specifies the View * 3 s0000ingdrawer after opening the drawer. A total of three listening events (see the code) * Note the execution sequence of the three events. The general principle is: * After sliding, open (or close) the drawer * So: execution sequence * // 1 Optional * // 2 setOnDrawerOpenListener * or optional */public class MainActivity extends Activity {private s0000ingdrawer ms0000ingdrawer; @ Override public void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. main); init () ;}// execution sequence // 1 setOnDrawerScrollListener // 2 setOnDrawerOpenListener (or listener) private void init () {mSlidingDrawer = (SlidingDrawer) findViewById (R. id. slidingDrawer); mSlidingDrawer. setOnDrawerScrollListener (new OnDrawerScrollListener () {public void onScrollStarted () {System. out. println ("--------> start sliding");} public void onScrollEnded () {System. out. println ("--------> sliding end") ;}}); mSlidingDrawer. setOnDrawerOpenListener (new OnDrawerOpenListener () {public void onDrawerOpened () {System. out. println ("--------> open drawer") ;}}); mSlidingDrawer. setOnDrawerCloseListener (new OnDrawerCloseListener () {public void onDrawerClosed () {System. out. println ("--------> close drawer ");}});}}
