SlidingPaneLayout也是系统支持的高级控件,是Android团对在2013 google IO大会期间更新的Support库(Version 13)中新加入的重要的功能。它支持左右滑动菜单,和SlidingMenu相似。这篇文章简单的介绍SlidingPaneLayout怎么使用,SlidingPaneLayout的使用和前面介绍的Navigation Drawer的使用无二异。

SlidingPaneLayout是一个水平的多层的布局控件,左侧或第一个视图是导航层,其他的为内容视图。

SlidingPaneLayout一般支持左侧滑出,没有右侧导航。


SlidingPaneLayout属于布局类:

<android.support.v4.widget.SlidingPaneLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/sliding_layout"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <ListView        android:id="@+id/sliding_list"        android:layout_width="150dp"        android:layout_height="match_parent"        android:background="#111"        android:choiceMode="singleChoice"        android:divider="@android:color/transparent"        android:dividerHeight="0dp" />    <FrameLayout        android:id="@+id/content_frame"        android:layout_width="300dp"        android:layout_height="match_parent"        android:layout_weight="1" /></android.support.v4.widget.SlidingPaneLayout>


使用 SlidingPaneLayout:
public class SlidingPaneLayoutActivity extends SherlockFragmentActivity {    private SlidingPaneLayout mSlidingPaneLayout;    private ListView mSliderList;    private ActionBarToggle mActionBarToggle;    private CharSequence mDrawerTitle;    private CharSequence mTitle;    private String[] mPlanetTitles;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_slider);        mTitle = mDrawerTitle = getTitle();        mPlanetTitles = getResources().getStringArray(R.array.planets_array);        mSlidingPaneLayout = (SlidingPaneLayout) findViewById(R.id.sliding_layout);        mSliderList = (ListView) findViewById(R.id.sliding_list);        // set a custom shadow that overlays the main content when the slider opens        mSlidingPaneLayout.setShadowResource(R.drawable.drawer_shadow);        // set up the slider's list view with items and click listener        mSliderList.setAdapter(new ArrayAdapter<String>(this,                R.layout.list_item, mPlanetTitles));        mSliderList.setOnItemClickListener(new DrawerItemClickListener());        // enable ActionBar app icon to behave as action to toggle sliding pane        getSupportActionBar().setHomeButtonEnabled(true);        // ActionBarDrawerToggle ties together the the proper interactions        // between the sliding pane and the action bar app icon        mActionBarToggle = new ActionBarToggle(                this,                  /* host Activity */                mSlidingPaneLayout,         /* SlidingPaneLayout object */                R.drawable.ic_drawer_light,  /* sliding pane  image to replace 'Up' caret */                R.string.slider_open,  /* "open drawer" description for accessibility */                R.string.slider_close  /* "close drawer" description for accessibility */                ) {        @Overridepublic void closeView() {                getSupportActionBar().setTitle(mTitle);                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()super.closeView();}                @Overridepublic void openView() {                getSupportActionBar().setTitle(mDrawerTitle);                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()super.openView();}        };        mSlidingPaneLayout.setPanelSlideListener(mActionBarToggle);        if (savedInstanceState == null) {            selectItem(0);        }    }    @Override    public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {    getSupportMenuInflater().inflate(R.menu.main, menu);    return super.onCreateOptionsMenu(menu);    }    @Override    public boolean onPrepareOptionsMenu(com.actionbarsherlock.view.Menu menu) {        // If the sliding pane is open, hide action items related to the content view        boolean drawerOpen = mSlidingPaneLayout.isOpen();        menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);    return super.onPrepareOptionsMenu(menu);    }        @Override    public boolean onOptionsItemSelected(    com.actionbarsherlock.view.MenuItem item) {        // The action bar home/up action should open or close the drawer.        // ActionBarDrawerToggle will take care of this.       if (mActionBarToggle.onOptionsItemSelected(item)) {           return true;       }       // Handle action buttons       switch(item.getItemId()) {       case R.id.action_websearch:           // create intent to perform web search for this planet           Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);           intent.putExtra(SearchManager.QUERY, getSupportActionBar().getTitle());           // catch event that there's no activity to handle intent           if (intent.resolveActivity(getPackageManager()) != null) {               startActivity(intent);           } else {               Toast.makeText(this, R.string.app_not_available, Toast.LENGTH_LONG).show();           }           return true;       default:           return super.onOptionsItemSelected(item);       }    }    /* The click listner for ListView in the navigation drawer */    private class DrawerItemClickListener implements ListView.OnItemClickListener {        @Override        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {            selectItem(position);        }    }    private void selectItem(int position) {        // update the main content by replacing fragments        Fragment fragment = new PlanetFragment();        Bundle args = new Bundle();        args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);        fragment.setArguments(args);                getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, fragment).commit();        // update selected item and title, then close the slider        mSliderList.setItemChecked(position, true);        setTitle(mPlanetTitles[position]);        mSlidingPaneLayout.closePane();    }    @Override    public void setTitle(CharSequence title) {        mTitle = title;        getSupportActionBar().setTitle(mTitle);    }    /**     * When using the ActionBarDrawerToggle, you must call it during     * onPostCreate() and onConfigurationChanged()...     */    @Override    protected void onPostCreate(Bundle savedInstanceState) {        super.onPostCreate(savedInstanceState);        // Sync the toggle state after onRestoreInstanceState has occurred.        mActionBarToggle.syncState();        getSupportActionBar().setDisplayHomeAsUpEnabled(mActionBarToggle.isDrawerIndicatorEnabled());    }    @Override    public void onConfigurationChanged(Configuration newConfig) {        super.onConfigurationChanged(newConfig);        // Pass any configuration change to the slider toggls        mActionBarToggle.onConfigurationChanged(newConfig);        getSupportActionBar().setDisplayHomeAsUpEnabled(mActionBarToggle.isDrawerIndicatorEnabled());    }        @Override    public void onBackPressed() {    if(mSlidingPaneLayout.isSlideable() && mSlidingPaneLayout.isOpen()){    mSlidingPaneLayout.closePane();    }    else{    super.onBackPressed();    }    }    /**     * Fragment that appears in the "content_frame", shows a planet     */    public static class PlanetFragment extends Fragment {        public static final String ARG_PLANET_NUMBER = "planet_number";        public PlanetFragment() {            // Empty constructor required for fragment subclasses        }        @Override        public View onCreateView(LayoutInflater inflater, ViewGroup container,                Bundle savedInstanceState) {            View rootView = inflater.inflate(R.layout.fragment_planet, container, false);            int i = getArguments().getInt(ARG_PLANET_NUMBER);            String planet = getResources().getStringArray(R.array.planets_array)[i];            int imageId = getResources().getIdentifier(planet.toLowerCase(Locale.getDefault()),                            "drawable", getActivity().getPackageName());            ((ImageView) rootView.findViewById(R.id.image)).setImageResource(imageId);            getActivity().setTitle(planet);            return rootView;        }    }}



SlidingPaneLayout的使用和Navigation Drawer相同,有疑问的地方可以参考demo。
