如何实现ListFragment和NavigationDrawerFragment

我想构建一个带有Fragment的Android应用程序，其中包含一个List of Option，如果我点击其中一个选项，我可以看到，另一个片段有其他选项。

所以我建立了这个：

activity_main.xml中

这是MainActivity.java

 public class MainActivity extends ActionBarActivity implements NavigationDrawerFragment.NavigationDrawerCallbacks{ private DrawerLayout drawer; private ListView leftList; private String[] leftListStrings; private String[] rightListStrings; private NavigationDrawerFragment mNavigationDrawerFragment; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); drawer = (DrawerLayout) findViewById(R.id.drawer_layout); leftList = (ListView) findViewById(R.id.left_list); leftListStrings = getResources().getStringArray(R.array.principal_menu); leftList.setAdapter(new ArrayAdapter(this,android.R.layout.simple_list_item_1,leftListStrings)); mNavigationDrawerFragment = (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.navigation_drawer); mNavigationDrawerFragment.setUp( R.id.navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout)); leftList.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) { arg1.setBackgroundColor(getResources().getColor(R.color.selected_menu_option)); if(arg2 == 0){ } } }); drawer.setDrawerListener(new DrawerLayout.DrawerListener() { @Override public void onDrawerStateChanged(int arg0) { // TODO Auto-generated method stub } @Override public void onDrawerSlide(View arg0, float arg1) { // TODO Auto-generated method stub } @Override public void onDrawerOpened(View arg0) { // TODO Auto-generated method stub } @Override public void onDrawerClosed(View arg0) { // TODO Auto-generated method stub //rightList.setVisibility(View.INVISIBLE); } }); } @Override public void onNavigationDrawerItemSelected(int position) { //TODO } class MayAdapter extends ArrayAdapter{ List myList = null; public MayAdapter(Context context, int resource, List objects) { super(context, resource, objects); myList = objects; } public List getMyList() { return myList; } public void setMyList(List myList) { this.myList = myList; } } public void restoreActionBar() { ActionBar actionBar = getSupportActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD); actionBar.setDisplayShowTitleEnabled(true); actionBar.setTitle("omnia"); } @Override public boolean onCreateOptionsMenu(Menu menu) { return super.onCreateOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); return super.onOptionsItemSelected(item); } } 

这是NavigationDrawerFragment.java

 public class NavigationDrawerFragment extends Fragment { private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position"; private NavigationDrawerCallbacks mCallbacks; private ActionBarDrawerToggle mDrawerToggle; private DrawerLayout mDrawerLayout; private ListView mDrawerListView; private View mFragmentContainerView; private int mCurrentSelectedPosition = 0; Toolbar toolBar; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (savedInstanceState != null) { mCurrentSelectedPosition = savedInstanceState.getInt(STATE_SELECTED_POSITION); } // Select the default item. selectItem(mCurrentSelectedPosition); } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); // the fragment has menu items to contribute setHasOptionsMenu(true); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { mDrawerListView = (ListView) inflater.inflate( R.layout.fragment_navigation_drawer, container, false); mDrawerListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView parent, View view, int position, long id) { selectItem(position); } }); mDrawerListView.setAdapter(new ArrayAdapter( getActionBar().getThemedContext(), android.R.layout.simple_list_item_activated_1, android.R.id.text1, new String[]{ getString(R.string.social_history), getString(R.string.encounter), getString(R.string.problems), })); mDrawerListView.setItemChecked(mCurrentSelectedPosition, true); return mDrawerListView; } private ActionBar getActionBar() { return ((AppCompatActivity) getActivity()).getSupportActionBar(); } public boolean isDrawerOpen() { return mDrawerLayout != null && mDrawerLayout.isDrawerOpen(mFragmentContainerView); } public void setUp(int fragmentId, DrawerLayout drawerLayout) { mFragmentContainerView = getActivity().findViewById(fragmentId); mDrawerLayout = drawerLayout; // set a custom shadow that overlays the main content when the drawer opens //mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); // set up the drawer's list view with items and click listener ActionBar actionBar = getActionBar(); actionBar.setDisplayHomeAsUpEnabled(true); actionBar.setHomeButtonEnabled(true); // ActionBarDrawerToggle ties together the the proper interactions // between the navigation drawer and the action bar app icon. mDrawerToggle = new ActionBarDrawerToggle( getActivity(), mDrawerLayout, null, R.string.navigation_drawer_open, R.string.navigation_drawer_close ) { @Override public void onDrawerClosed(View drawerView) { super.onDrawerClosed(drawerView); if (!isAdded()) { return; } getActivity().supportInvalidateOptionsMenu(); } @Override public void onDrawerOpened(View drawerView) { super.onDrawerOpened(drawerView); if (!isAdded()) { return; } getActivity().supportInvalidateOptionsMenu(); } }; mDrawerLayout.post(new Runnable() { @Override public void run() { mDrawerToggle.syncState(); } }); mDrawerLayout.setDrawerListener(mDrawerToggle); mDrawerToggle.setDrawerIndicatorEnabled(true); } private void selectItem(int position) { mCurrentSelectedPosition = position; if (mDrawerListView != null) { mDrawerListView.setItemChecked(position, true); } if (mDrawerLayout != null) { mDrawerLayout.closeDrawer(mFragmentContainerView); } if (mCallbacks != null) { mCallbacks.onNavigationDrawerItemSelected(position); } } @Override public void onAttach(Activity activity) { super.onAttach(activity); try { mCallbacks = (NavigationDrawerCallbacks) activity; } catch (ClassCastException e) { throw new ClassCastException("Activity must implement NavigationDrawerCallbacks."); } } @Override public void onDetach() { super.onDetach(); mCallbacks = null; } @Override public void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putInt(STATE_SELECTED_POSITION, mCurrentSelectedPosition); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); mDrawerToggle.onConfigurationChanged(newConfig); } @Override public boolean onOptionsItemSelected(MenuItem item) { if (mDrawerToggle.onOptionsItemSelected(item)) { return true; } return super.onOptionsItemSelected(item); } public static interface NavigationDrawerCallbacks { void onNavigationDrawerItemSelected(int position); } } 

使用此代码，如果我尝试运行我的应用程序，我可以看到这样的完整菜单

相反，我想只看到左侧菜单，如果我点击一个项目，请参阅右侧菜单
