creating base activity with navigation drawer in android

问题:

I tried to follow this answer, with the main idea is to override the setContentView in the BaseActivity, the activity that will be extended by all activity so only BaseActivity will have the navigation drawer.

However, my navigation is never shown (even in BaseActivity) after i tried to implement the answer. This is what i did :

This is the navigation drawer's xml :

This is my overrided setContentView (in BaseActivity) :

@Override     public void setContentView(int layoutResID) {         // TODO Auto-generated method stub         mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); // Your base layout here         actContent= (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);         //listLayout = (LinearLayout) mDrawerLayout.findViewById(R.id.listLayout);         getLayoutInflater().inflate(layoutResID, actContent, true);         //getLayoutInflater().inflate(layoutResID, listLayout, true);         super.setContentView(layoutResID);     } 

And this is my onCreate on BaseActivity, note that i use getLayoutInflater().inflate instead of setContentView :

@Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         //setContentView(R.layout.activity_main);          //getSupportActionBar().setDisplayShowHomeEnabled(false);         //getSupportActionBar().setDisplayShowCustomEnabled(true);         // enabling action bar app icon and behaving it as toggle button         getSupportActionBar().setDisplayHomeAsUpEnabled(true);         getSupportActionBar().setHomeButtonEnabled(true);          mTitle = mDrawerTitle = getTitle();          // load slide menu items         navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);          // nav drawer icons from resources         navMenuIcons = getResources()                 .obtainTypedArray(R.array.nav_drawer_icons);          //mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);         mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null);         //mDrawerList = (ListView) findViewById(R.id.list_slidermenu);         mDrawerList = (ListView) mDrawerLayout.findViewById(R.id.list_slidermenu);          navDrawerItems = new ArrayList();          // adding nav drawer items to array         // Home         navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));         // Find People         navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));         // Photos         navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));         // Communities, Will add a counter here         navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1)));         // Pages         navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));         // What's hot, We  will add a counter here         navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));           // Recycle the typed array         navMenuIcons.recycle();          mDrawerList.setOnItemClickListener(new SlideMenuClickListener());          // setting the nav drawer list adapter         adapter = new NavDrawerListAdapter(getApplicationContext(),                 navDrawerItems);         mDrawerList.setAdapter(adapter);          mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,                 R.drawable.ic_drawer, //nav menu toggle icon                 R.string.app_name, // nav drawer open - description for accessibility                 R.string.app_name // nav drawer close - description for accessibility         ) {             public void onDrawerClosed(View view) {                 getSupportActionBar().setTitle(mTitle);                 // calling onPrepareOptionsMenu() to show action bar icons                 invalidateOptionsMenu();             }              public void onDrawerOpened(View drawerView) {                 getSupportActionBar().setTitle(mDrawerTitle);                 // calling onPrepareOptionsMenu() to hide action bar icons                 invalidateOptionsMenu();             }         };         mDrawerLayout.setDrawerListener(mDrawerToggle);          if (savedInstanceState == null) {             // on first time display view for first nav item             displayView(0);         }      } 

And finally, i just need to extend the BaseActivity class and code like usual.

UPDATE

According to the answer, this is my WORKING overrided setContentView :

@Override     public void setContentView(final int layoutResID) {         // TODO Auto-generated method stub         mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); // Your base layout here         actContent= (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);          getLayoutInflater().inflate(layoutResID, actContent, true);         super.setContentView(mDrawerLayout);          mTitle = mDrawerTitle = getTitle();          // load slide menu items         navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);          // nav drawer icons from resources         navMenuIcons = getResources()                 .obtainTypedArray(R.array.nav_drawer_icons);          mDrawerList = (ListView) mDrawerLayout.findViewById(R.id.list_slidermenu);          navDrawerItems = new ArrayList();          // adding nav drawer items to array         // Home         navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));         // Find People         navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));         // Photos         navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));         // Communities, Will add a counter here         navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1)));         // Pages         navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));         // What's hot, We  will add a counter here         navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));           // Recycle the typed array         navMenuIcons.recycle();          mDrawerList.setOnItemClickListener(new SlideMenuClickListener());          // setting the nav drawer list adapter         adapter = new NavDrawerListAdapter(getApplicationContext(),                 navDrawerItems);         mDrawerList.setAdapter(adapter);          mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,                 R.drawable.ic_drawer, //nav menu toggle icon                 R.string.app_name, // nav drawer open - description for accessibility                 R.string.app_name // nav drawer close - description for accessibility         ) {             public void onDrawerClosed(View view) {                 getSupportActionBar().setTitle(mTitle);                 // calling onPrepareOptionsMenu() to show action bar icons                 invalidateOptionsMenu();             }              public void onDrawerOpened(View drawerView) {                 getSupportActionBar().setTitle(mDrawerTitle);                 // calling onPrepareOptionsMenu() to hide action bar icons                 invalidateOptionsMenu();             }         };         mDrawerLayout.setDrawerListener(mDrawerToggle);          //super.setContentView(mDrawerLayout);         /*getLayoutInflater().inflate(layoutResID, actContent, true);         super.setContentView(mDrawerLayout);*/     } 

回答1:

Change your setContentView() like this...

@Override public void setContentView(int layoutResID) {     mDrawerLayout = (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null);      actContent = (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);     // set the drawer layout as main content view of Activity.     setContentView(mDrawerLayout);     // add layout of BaseActivities inside framelayout.i.e. frame_container     getLayoutInflater().inflate(layoutResID, actContent, true); }

I know this is already answered, but in case someone struggles with my specific problem:

DrawerLayout can only have 2 childs, content and the navigationView. if you want to include a toolbar you should wrap this inside another layout or outside the drawerlayout:

DrawerLayout --LinearLayout (or any other layout) ----Toolbar ----Content --NavigationView 

or:

LinearLayout (or any other layout) --Toolbar --DrawerLayout ----Content ----NavigationView
