Hamburger Icon not opening Navigation Drawer on parent fragment after returning from child fragment by clicking back arrow on toolbar

The app I am building uses navigation drawer android.support.v4.widget.DrawerLayout and MainActivity extends android.support.v7.app.AppCompatActivity. I have a parent fragment that is replaced by child fragment. On parent fragment default hamburger icon is properly toggling the navigation drawer. While on child fragment, hamburger icon is replaced by back arrow icon using this snippet
((MainActivity)getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar = (Toolbar) (getActivity()).findViewById(R.id.toolbar);
((MainActivity)getActivity()).setSupportActionBar(toolbar);
On child fragment back button click event is handled on onOptionsItemSelected() and hamburger icon is shown again for parent fragment on onStop().
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
getActivity().onBackPressed();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public void onStop() {
super.onStop();
((MainActivity)getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(false);
MainActivity.toggle.syncState();
}
On parent fragment hamburger icon is now showing properly but on clicking it the navigation drawer doesn't show up again.
Could anyone please help on what am I doing wrong?
Here are the relevant files:
MainActivity.java
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
public static ActionBarDrawerToggle toggle;
#Override

setSupportActionBar(toolbar);
try {
Fragment fragment = (Fragment) ParentFragment.class.newInstance();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_content, fragment).commit();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {

}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

toggle = MainActivity.toggle;

toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentManager manager = getActivity().getSupportFragmentManager();
manager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
toggle.setDrawerIndicatorEnabled(true);
}
});
toolbar = (Toolbar) (getActivity()).findViewById(R.id.toolbar);
toolbar.setNavigationIcon(((MainActivity)getActivity()).getDrawerToggleDelegate().getThemeUpIndicator());
}
#Override
public void onStop() {
super.onStop();
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
default:
return super.onOptionsItemSelected(item);
}
}
}

android toolbar with fragments

I have toolbar and framelayout(for fragments) in my main activity layout. I have to show the toolbar in every fragments. But the issue is each fragment has different background image that is dynamically changing. Toolbar menu icon is used for navigation drawer open and close operation. How I will handle these issue?

Before posting the code block let's first understand what are we are going to do.
1.Create a HomeActivity that holds all the fragments.
Here is the activity_home.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_home"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_home"
app:menu="#menu/activity_home_drawer" />
</android.support.v4.widget.DrawerLayout>
Here is the app_bar_home.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
the other xmls of navigationview -- activity_home_drawer.xml contains navigation drawer contents and nav_header_home.xml is the navigation drawer header layout.
2.Let's come to java part of the HomeActivity.java
public class HomeActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener{
private HomeBean bean;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
ButterKnife.bind(this);
initListener();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//this menu contains all the common menu item actions
getMenuInflater().inflate(R.menu.home, menu);
return true;
}
//common options bar item click here i have notifications icon common for all the fragments
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
switch (item.getItemId()){
case R.id.action_notifications:
AppUtils.launchActivity(HomeActivity.this, NotificationActivity.class,intentData);
return false;
default:
return super.onOptionsItemSelected(item);
}
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
// Handle navigation view item clicks here.
Fragment selectedFragment = null;
switch (item.getItemId()){
case R.id.nav_dashboard:
//you can cache this fragment in case of repeated creations
selectedFragment = new DashBoardFragment();
}
break;
}
if(selectedFragment != null){
displayFragment(selectedFragment);
DrawerLayout drawer = ButterKnife.findById(this,R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
}
return true;
}
private void displayFragment(Fragment fragment) {
if(fragment !=null){
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.content_frame, fragment);
ft.commit();
}
}
#Override
public void initToolBar() {}
public void setToolbar(Toolbar toolbar){
setSupportActionBar(toolbar);
setActionBarToggle(toolbar);
}
private void setActionBarToggle(Toolbar toolbar) {
DrawerLayout drawer = ButterKnife.findById(this, R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open,
R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
}
#Override
public void initListener() {
NavigationView navigationView = ButterKnife.findById(this,R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
//as the first item is show by default
navigationView.getMenu().getItem(0).setChecked(true);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
}
Now as an example let see how the fragments are written.
public class SettingsFragment extends Fragment {
#BindView(R.id.toolbar)
Toolbar toolbar;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_settings,container,false);
ButterKnife.bind(this,view);
return view;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
((HomeActivity)getActivity()).setToolbar(toolbar);
}
}

<?xml version="1.0" encoding="utf-8"?>

app:layout_behavior="#string/appbar_scrolling_view_behavior">
// your content goes here
</<android.support.v4.widget.NestedScrollView>
I hope this gives clear picture on how to do in case if you have any other doubts please comment.

Use this code. I helped
public class MyFragment extends Fragment {
public void onCreate(Bundle savedInstanceState) {
setHasOptionsMenu(true);// To enable actionbar in fragments
super.onCreate(savedInstanceState);
}
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
//Here it is necessary to connect the layout menu
inflater.inflate(R.menu.fragment2, menu);
super.onCreateOptionsMenu(menu, inflater);
}
}

Check code output in gif image below

Make sure that everything within your left-drawer-layout is clickable. Otherwise, clicks will be passed to the underlying view, in this case to your main-content. You can do so by setting an OnClickListener to the rootview of your FragmentDrawer:
myFragmentInsideTheDrawer.getView().setOnClickListener(new OnClickListener() {
#Override
public void onClick(View pView) {
// do nothing here, just intercept click-events
}
});

In inDrawerOpen method you can use yourcontentlayout.setEnabled(false) and in onDrawerClosed method yourcontentlayout.setEnabled(true)
Hope this helps!

Up Navigation (Action Bar's back arrow) is not working for fragments

I've drawer-layout as a base layout of my activity and I'm replacing two fragments on a frame present inside this drawer-layout. The first fragment is not added in fragment's back stack. I'm displaying hamburger icon in my activity (I also want the drawer menu in my first fragment). In second fragment I disabled the hamburger icon by mActionBarDrawerToggle.setDrawerIndicatorEnabled(false) and enabled back button using actionBar.setDisplayHomeAsUpEnabled(true).
In first fragments onResume I enabled hamburger icon by mActionBarDrawerToggle.setDrawerIndicatorEnabled(true)` so that when user presses back button (both hardware and action-bar's up button) from second fragment,user will come back to first fragment and hamburger icon will be enabled. Everything is working fine only I'm not able to go back from second fragments action bar back button. I'm not able to click it.
Below is my code :-
Activity code
if (Utility.isLargeScreen(this))
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
else
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
mHiddenGemsApplication = (HiddenGemsApplication) getApplication();
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
initViews();
setSupportActionBar(mToolbar);
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
}
mTextViewActionBarTitle.setText(getString(R.string.app_name));
mActionBarDrawerToggle = new ActionBarDrawerToggle(HomeActivity.this, mDrawerLayout, mToolbar, R.string.open_drawer, R.string.close_drawer) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
mDrawerLayout.setDrawerListener(mActionBarDrawerToggle);
mActionBarDrawerToggle.syncState();
mFragmentManager = getSupportFragmentManager();
replaceFragment(new CategoryFragment(), getString(R.string.app_name), CategoryFragment.TAG);
#Override
public void onBackPressed() {
if (mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
mDrawerLayout.closeDrawers();
return;
}
super.onBackPressed();
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
if (mFragmentManager.getBackStackEntryCount() > 0) {
mFragmentManager.popBackStack();
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public void replaceFragment(Fragment fragment, String actionBarTitle, String tag) {
if (mFragmentManager == null)
return;
FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.content_frame, fragment, tag);
if (!tag.equals(CategoryFragment.TAG))
fragmentTransaction.addToBackStack(tag);
fragmentTransaction.commit();
setActionBarTitle(actionBarTitle);
}
public void setActionBarTitle(String actionBarTitle) {
if (!TextUtils.isEmpty(actionBarTitle))

Second Fragment

actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_trip_list, container, false);
}
#Override
public void onResume() {
super.onResume();
((HomeActivity) mActivity).setDrawerIndicatorEnabled(false);
}
Also, when I'm in second fragment I'm able to swipe and see the drawer menu. I don't want this behaviour, drawer menu should only open in fragment 1.
If any thing is wrong in my code please let me know.

Finally got the answer. In my scenario I'm disabling the drawer indicator by mActionBarDrawerToggle.setDrawerIndicatorEnabled(false); and due to this Navigation icon clicks got disabled. To enable this I've to add ToolbarNavigationClickListener to ActionBarDrawerToggle which will enable navigation icon clicks.
Below is the my working code :-
mActionBarDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});
Refer this link for more clarification

After struggling with the same problem for ages, I eventually managed to get the Up button to work in fragments with this code.
You must have setHasOptionsMenu set up in onCreate() or onCreateView()
setHasOptionsMenu(true);
Then, in onOptionsItemSelected() add this check for the up / home button being pressed to your switch() [or if...] statement:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
x.L();
switch (item.getItemId()) {
case android.R.id.home :
getActivity().onBackPressed();
break;
case R.id.mn_exit :
exitFragment();
break;
default :
break;
}
return super.onOptionsItemSelected(item);
}

The issue with toolbar and navigation View

I have one activity, inside I have toolbar and navigationView.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.start_page_activity);
getFragment(new MainFragment());
mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
mNavigationView = (NavigationView) findViewById(R.id.main_drawer);
mNavigationView.setNavigationItemSelectedListener(this);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_widget);
drawerToggle
= new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R.string.drawer_open, R.string.drawer_close);
mDrawerLayout.setDrawerListener(drawerToggle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
Log.i("StartPageActivity", "onPostCreate");
drawerToggle.syncState();
}
When starting activity at first called Main Fragment.
When I select item in NavigationView opens new Fragment.
when appear second fragment, inside I use
ActionBar a = ((AppCompatActivity) getActivity()).getSupportActionBar();
a.setDisplayHomeAsUpEnabled(true);
Up arrow appeared, but when I click on this Up arrow opens NavigationVIEW!!!
in fragment inside onOptionsItemSelected I HAVE
case android.R.id.home:{
Log.i("One", "Dude");
}
The program does not comply with this code. It does not come to it. I think the problem inside onCreate (activity). Maybe it conflict between ActionBarDrawerToggle, NavigationView and Toolbar.
ADD second fragment
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.reminder_list_fragment, container, false);
getActivity().setTitle("Fragment1");
mRecyclerView = (RecyclerView)v. findViewById(R.id.my_recycler_view);
//{RecyclerAdapter}
ActionBar a = ((AppCompatActivity) getActivity()).getSupportActionBar();
a.setDisplayHomeAsUpEnabled(true);
a.setHomeButtonEnabled(true);
return v;
}
#Override
public void onResume() {
super.onResume();
mRecyclerView.getAdapter().notifyDataSetChanged();
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
inflater.inflate(R.menu.reminder_toolbar, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
Log.d("Testing", "ID == " + id);
switch (id) {
case R.id.add_information : {
Forget f = new Forget();
ForgetLab.get(getActivity()).addForget(f);
FragmentManager fm = getFragmentManager();
Fragment mFragment = fm.findFragmentById(R.id.fragment_container);
Bundle bundle = new Bundle();
bundle.putSerializable(ReminderFragment.EXTRA_FORGET_ID, f.getId());
if (mFragment != null) {
mFragment = new ReminderPagerFragment();
mFragment.setArguments(bundle);
fm.beginTransaction().addToBackStack(null)
.replace(R.id.fragment_container, mFragment)
.commit();
}
return true;
}
case android.R.id.home:{
Log.i("One", "Dude");
}
}
return super.onOptionsItemSelected(item);
}

You should overRide onOptionsItemSelected(MenuItem item) and setHasOptionsMenu(true) should be called inside onCreate(Bundle savedInstanceState)
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == android.R.id.home) {
getActivity().onBackPressed();
}

} I hope this works....

Use this complete example.

return;
}
initToolbar();

You Main activity must extends BaseActivity
public class MainActivity extends BaseActivity {

super.onCreate(savedInstanceState);
if (!LoginManager.isFirstFlowFinished(this)) {
LoginManager.launchCurrentFragment(this);
finish();
return;
}
Intent intent = getIntent();
handleIntent(intent);
setContentView(R.layout.activity_main_new);
LogUtils.LOGD(">>Intent", "onCreate");
}
#Override
public void onResume() {
super.onResume();
LocationTracker.promptIfNeededForEnableLocation(this);
CommonUtils.checkIfPlayServicesNeedToUpdate(this);
AppEventsLogger.activateApp(this);
}
#Override
protected void onPause() {
super.onPause();
AppEventsLogger.deactivateApp(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_search, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_search_icon:
ActivityUtils.launchSearchActivity(this);
break;
}
return true;
}
#Override
public void onBackPressed() {
super.onBackPressed();
}
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
LogUtils.LOGD(">>Intent", "on handle Intent");
handleIntent(intent);
}
}
