Demo directory structure:

Key code:

MainActivity. java

Package com. dzt. slidingmenudemo; import android. OS. bundle; import android. support. v4.app. fragmentActivity; import com. slidingmenu. lib. sshortingmenu; public class MainActivity extends FragmentActivity {private sshortingmenu mChannelMenu; @ Overridepublic void onCreate (Bundle savedInstanceState) {// TODO Auto-generated method stubsuper. onCreate (savedInstanceState); // set the title of the title bar setTitle ("test SlidingMenu"); setConten TView (R. layout. main_activity); initChannelMenu ();} private void initChannelMenu () {// create the SlidingMenu object mChannelMenu = new SlidingMenu (this); // set the position of the slide menu, which is on the left. When the menu is pulled, mChannelMenu is displayed on the left. setMode (SlidingMenu. LEFT); // set the touch range. Here, the full screen mChannelMenu is set. setTouchModeAbove (sregistringmenu. TOUCHMODE_FULLSCREEN); // set the shadow width. Check the second one on the top and place it on the right. There is a shadow transition. This is the mChannelMenu. setShadowWidthRes (R. dimen. shadow_width); // specifies the shadow effect. You can set an image or a color transition mChannelMenu. setShadowDrawable (R. drawable. shadow); // set the spacing between the backend and the sliding column and the original interface. setBehindOffsetRes (R. dimen. slidingmenu_offset); // border angle. mChannelMenu indicates the border. setFadeDegree (0.35f); // sets the mChannelMenu mode for the touch screen. setTouchModeAbove (sregistringmenu. TOUCHMODE_FULLSCREEN); // associate the slide bar with the current ActivitymChannelMenu. attachToActivity (this, SlidingMenu. SLIDING_CONTENT); // The layout file mChannelMenu in the slide bar. setMenu (R. layout. channel_slide_menu); getSupportFragmentManager (). beginTransaction (). replace (R. id. menu_frame, new MyListFragment ()). commit () ;}@ Overridepublic void onBackPressed () {if (mChannelMenu. isMenuShowing () {// hide the SlidingMenu. The Content here is our main ActivitymChannelMenu. showContent ();} else {super. onBackPressed ();}}}

MyListFragment. java

Package com. dzt. slidingmenudemo; import android. content. context; import android. OS. bundle; import android. support. v4.app. listFragment; import android. view. layoutInflater; import android. view. view; import android. view. viewGroup; import android. widget. arrayAdapter; import android. widget. imageView; import android. widget. textView; public class MyListFragment extends ListFragment {public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {return inflater. inflate (R. layout. list, null);} public void onActivityCreated (Bundle savedInstanceState) {super. onActivityCreated (savedInstanceState); SampleAdapter adapter = new SampleAdapter (getActivity (); for (int I = 0; I <20; I ++) {adapter. add (new SampleItem ("list on the left", android. r. drawable. ic_menu_search);} setListAdapter (adapter);} private class SampleItem {public String tag; public int iconRes; public SampleItem (String tag, int iconRes) {this. tag = tag; this. iconRes = iconRes;} public class SampleAdapter extends ArrayAdapter <SampleItem> {public SampleAdapter (Context context) {super (context, 0);} public View getView (int position, View convertView, viewGroup parent) {if (convertView = null) {convertView = LayoutInflater. from (getContext ()). inflate (R. layout. item, null);} ImageView icon = (ImageView) convertView. findViewById (R. id. row_icon); icon. setImageResource (getItem (position ). iconRes); TextView title = (TextView) convertView. findViewById (R. id. row_title); title. setText (getItem (position ). tag); return convertView ;}}}

One thing to note, in the use of the project will be generated by default: android-support-v4.jar, there may be conflicts with SlidingMenu, need to delete, otherwise it will report an error.

The latest SlidingMenu can be downloaded from Git.

Now, is it better for android to use the SlidingMenu open-source project to slide the menu bar, or is it better to use the Navigation Drawer that comes with android?

If you are learning the code, it is recommended to study the official version. However, SlidingMenu has many functions, such as controlling the background behind the menu when sliding out. It seems that the background of Navigation Drawer cannot be moved. It is a trend to replace open-source projects with official APIs, because everyone thinks that official interfaces are safe to use, but open-source projects may be more flexible.
