I am creating simple app having DrawerLayout navigation. In which one menu item is My Profile. In My profile Screen there is button which open Change Password screen in same Fragment. if i open DrawerLayout 's menu and close it without clicking, then My Profile Screen loads again.
Following is my code
public class HomeActivity extends ActionBarActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private ArrayList<SideMenuEntity> listSideMenuItems;
private SideMenuAdapter adapterSideMenu;
Menu menu;
Fragment fragment;
AsyncTaskHelper loadFragmentTask;
int position, old_position;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
mTitle = mDrawerTitle = getTitle();
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
listSideMenuItems = new ArrayList<>();
for(String str : Constant.SIDE_MENU_ITEMS)
{
listSideMenuItems.add(new SideMenuEntity(str));
}
// setting the nav drawer list adapter
adapterSideMenu = new SideMenuAdapter(getApplicationContext(),listSideMenuItems);
mDrawerList.setAdapter(adapterSideMenu);
mDrawerList.setOnItemClickListener(new ListView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
displayView(position);
}
});
ActionBar actionbar = getSupportActionBar();
actionbar.setDisplayHomeAsUpEnabled(true);
actionbar.setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.mipmap.ic_launcher,R.string.app_name, R.string.app_name)
{
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitle);
invalidateOptionsMenu();
if (fragment != null) {
_setFragmentContainer(fragment, listSideMenuItems.get(position).title);
}
}
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null)
{
old_position = -1;
displayView(-1);
_setFragmentContainer(fragment, listSideMenuItems.get(position).title);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
this.menu = menu;
getMenuInflater().inflate(R.menu.menu_home_setting, menu);
_setActionBarHomeVisible(false);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// toggle nav drawer on selecting action bar app icon/title
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle action bar actions click
switch (item.getItemId())
{
case R.id.title_bar_home:
displayView(0);
return true;
case R.id.title_bar_setting:
_setFragmentContainer(new SettingFragment(), "Setting");
return true;
default:
return super.onOptionsItemSelected(item);
}
}
/***
* Called when invalidateOptionsMenu() is triggered
*/
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
return super.onPrepareOptionsMenu(menu);
}
/**
* Diplaying fragment view for selected nav drawer list item
*
*/
protected void displayView(int p)
{
position = p >= 0 ? p : 0;
fragment = null;
switch (position)
{
case Constant.SIDE_MENU_ITEM_DAHSHBOARD:
fragment = new DashboardFragment();
break;
case Constant.SIDE_MENU_ITEM_MY_PROFILE:
fragment = new MyProfileFragment();
break;
}
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
mDrawerLayout.closeDrawer(mDrawerList);
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getSupportActionBar().setTitle(mTitle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
/**-------------- private functions ---------------------*/
public void _setFragmentContainer(Fragment fragment, String title)
{
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame_container, fragment).commit();
setTitle(title);
}
}
Try adding the super constructor:
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getSupportActionBar().setTitle(mTitle);
invalidateOptionsMenu();
if (fragment != null) {
_setFragmentContainer(fragment, listSideMenuItems.get(position).title);
}
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getSupportActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
i solve the problem my self own. actually whenever DrawerLayout closed, onDrawerClosed event fired, then i just null the fragment variable after _setFragmentContainer() function
if (fragment != null)
{
_setFragmentContainer(fragment, listSideMenuItems.get(position).title);
fragment = null;
}
Now DrawerLayout Menu closed, due to fragment null , it don't load fragment again.

I'm using NavigationDrawer as the main activity, but when I go to another fragment I want to modify the menu, putting an arrow to back to the home and hide the search icon of the navbar, so I'm having two problems here, I can hide the search icon when I change the fragment, but when I'm back to the navigationMain it should be visible again, which is not happening, and if I am in another fragment the navigation bar must be removed and an arrow back must appear so I can get back to home, this is what I've tried so far:
public class NavigationMain extends ActionBarActivity{
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private android.support.v7.app.ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_main);
mPlanetTitles = getResources().getStringArray(R.array.planets_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
toolbartitle = (TextView) findViewById(R.id.titletool);
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
mDrawerToggle = new android.support.v7.app.ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
toolbar, /* nav drawer image to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
//getSupportActionBar().setTitle(mTitle);
toolbartitle.setText(mTitle);
getSupportActionBar().setDisplayShowTitleEnabled(false);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
//getSupportActionBar().setTitle(mDrawerTitle);
toolbartitle.setText(mDrawerTitle);
getSupportActionBar().setDisplayShowTitleEnabled(false);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
setSupportActionBar(toolbar);
mDrawerLayout.setDrawerListener(mDrawerToggle);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbartitle.setText("Nav");
toolbar.inflateMenu(R.menu.main);
mDrawerToggle.syncState();
if (savedInstanceState == null) {
selectItem(0);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return super.onCreateOptionsMenu(menu);
}
/* Called whenever we call invalidateOptionsMenu() */
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// If the nav drawer is open, hide action items related to the content view
return super.onPrepareOptionsMenu(menu);
}
#Override

// The action bar home/up action should open or close the drawer.
// ActionBarDrawerToggle will take care of this.
if (mDrawerToggle.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, toolbartitle.getText());
// 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) {
FragmentManager fragmentManager = getSupportFragmentManager();
Fragment fragment = new InstituicoesFragment();
switch (position) {
case 0:
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
break;
}
// Load your conten here
Toast.makeText(NavigationMain.this, "Position" + position, Toast.LENGTH_LONG).show();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerLayout.closeDrawer(mDrawerList);
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
//getSupportActionBar().setTitle(mTitle);
toolbartitle.setText(mTitle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public void onBackPressed() {
super.onBackPressed();
}
}
In my Fragment I add the following:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.main, menu);
menu.removeItem(R.id.action_websearch);
super.onCreateOptionsMenu(menu, inflater);
}
i used this method :
i inflate the menu for the actionbar with all the items already in.
then in the Activity onCreateOptionsMenu() i check wich fragment is displayed and i set the visibility of the items accordingly.
then in the onSectionAttached method i call invalidateOptionsMenu(); that will reload the onCreateOptionsMenu so i can have different menu items on each fragment selected
for checking i use boolean flags and if the flag is true it means that the fragment is n view, like:
viewing the first fragment:
ft.replace(R.id.container, firstFragment);
firstfragmentIsOn=true;
secondFragmentIsOn=false;
viewing the second fragment:
ft.replace(R.id.container, secondFragment);
firstfragmentIsOn=false;
secondFragmentIsOn=true;
and in the onCreateOptionsMenu:
MenuItem item1=menu.findItem(R.id.item1);
MenuItem item2=menu.findItem)(R.id.item2);
if(firstfragmentIsOn)
{
item1.setVisible(true);
item2.setVisible(false);
}
if(secondFragmentIsOn)
{
item1.setVisible(false);
item2.setVisible(true);
}
Please I have a problem, in my code like its nothing wrong, why when I select content on Sliding Menu, Sliding menus are not automatically covered? What's wrong with my code? I do not use a fragment only uses a switch to display the menu

When I select an item from the drawer, it will add a new Fragment to the activity container.
Each fragment have it's own menu, as shown in the following example:
EventInformationFragment.java
public class EventInformationFragment extends Fragment
{
private View rootView = null;
private EventActivity mainActivity = null;
private GoogleMap mMap;
private boolean isStaff = false;
private LayoutInflater inflater = null;
private ViewGroup container = null;
private TextView forCopy = null;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
if(EventActivityHelper.getHelper().inSchedule)
{
return null;
}
mainActivity = (EventActivity) GlobalContents.getNowActivity();
mainActivity.getActionBar().setTitle(R.string.Event);
this.inflater = inflater;
this.container = container;
GlobalContents.dismissProgressBar();
if(!GlobalContents.getGlobalContents().getAuthenticatedUser().isStaff())
{
return elaborateAttendeeView();
}
isStaff = true;
return elaborateStaffView();
}
private View elaborateAttendeeView()
{
... NOT IMPORTANT ...
}
private View elaborateStaffView()
{
... NOT IMPORTANT ...
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
if(menu.hasVisibleItems())
menu.clear();
if(isStaff)
inflater.inflate(R.menu.event, menu);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public void onPrepareOptionsMenu(Menu menu)
{
if(menu.hasVisibleItems())
menu.clear();
MenuInflater inflater = getActivity().getMenuInflater();
if(isStaff)
inflater.inflate(R.menu.event, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.action_edit:
mainActivity.getSupportFragmentManager()
.beginTransaction()
.remove(mainActivity.currentFragment)
.remove(getFragmentManager().findFragmentById(R.id.map))
.commit();
mainActivity.currentFragment = new EventEditInformationFragment();
mainActivity.getSupportFragmentManager().beginTransaction()
.add(R.id.container, mainActivity.currentFragment).commit();
break;
}
return super.onOptionsItemSelected(item);
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
{
... NOT IMPORTANT ...
}
#Override
public boolean onContextItemSelected(MenuItem item)
{
... NOT IMPORTANT ...
}
}
Here is the exact part of EventInformationFragment that I inflates the menu:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
if(menu.hasVisibleItems())
menu.clear();
if(isStaff)
inflater.inflate(R.menu.event, menu);
super.onCreateOptionsMenu(menu, inflater);
}
The problem is: when I open the Fragment through the NavigationDrawerFragment, the menu doesn't inflate!
In the EventInformationFragment, I intent to another activity, and, onResume this activity, the menu inflates!
What am I doing wrong?
Here is the activity that has the NavigationDrawerFragment and, at some point, EventInformationFragment
EventActivity.java
public class EventActivity extends ActionBarActivity

After a lot of search and tries, I've managed to make it work.
Before I commit the Fragment, I've placed an invalidateOptionsMenu().
It works now.
Can someone suggest me a tutorial how to create a BaseActivity for the Android Navigation Drawer ?
Or can anyone post a sample BaseActivity for the Navigation Drawer including the layout ?
Download sample Code from Google n i have edited that code as basic navigation drawer with fragment no imageview

You can achieve this with the help of fragments. Go through following which have sample code and video tutorial.

I have one problem, how to implement a merchandising display before starting my navigation drawer. this is my code. Thanks for help guys.
This is my code merchan, but is wrong, I want to call this screen before the application itself, which is basically a navigation drawer.
public class Merchan extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.merchan);
Thread logoTimer = new Thread() {
public void run() {
try {
sleep(3000);
Intent menuIntent = new Intent("com.codehevea.menu.Main");
startActivity(menuIntent);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
finish();
}
}
};
logoTimer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
}
}
And this is my principal class. It should boot screen after merchandising.
public class Main extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mMenuTitles;
#Override

setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
mMenuTitles = getResources().getStringArray(R.array.menu_array);

mDrawerList = (ListView) findViewById(R.id.left_drawer);
// 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
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mMenuTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer

You're using the wrong Intent constructor. Change it to something like:
Intent menuIntent = new Intent(this, com.codehevea.menu.Main.class);
Note, if the current and target class are in the same package, you don't need the package name, so:
Intent menuIntent = new Intent(this, Main.class);
