Showing hamburger icon on a custom toolbar?

I made a NavigationView and included getSupportActionBar().setDisplayHomeAsUpEnabled(true);in my code to show the hamburger button, and it worked. but then i removed the default toolbar (by setting AppTheme in styles values to parent="Theme.AppCompat.Light.NoActionBar"), and implemented my own toolbar in the layout. And now instead of the Hamburger button, it shows the back button, although clicking on it draws the NavigationView. What should i do?
My Java code:
private DrawerLayout sideBar;
private ActionBarDrawerToggle sideBarToggle;
private Toolbar actionToolbar;
#Override
public void onCreate(...) {
sideBar = (DrawerLayout) findViewById(R.id.sqliteLayout);
sideBarToggle = new ActionBarDrawerToggle(this, sideBar, actionToolbar, R.string.sideBarOpen, R.string.sideBarClose);
actionToolbar = (Toolbar) findViewById(R.id.navAction);
sideBar.addDrawerListener(sideBarToggle);
sideBarToggle.syncState();
setSupportActionBar(actionToolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(sideBarToggle.onOptionsItemSelected(item)){
return true;}
return super.onOptionsItemSelected(item);
}
My Toolbar code:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/navAction"
android:background="#color/colorPrimary"
app:theme="#style/Base.Theme.AppCompat.Light.DarkActionBar">
</android.support.v7.widget.Toolbar>
SOLUTION:
I reordered the java code to this, and removed the 3rd argument in new ActionBarDrawerToggle(...) and it worked!
actionToolbar = (Toolbar) findViewById(R.id.navAction);
setSupportActionBar(actionToolbar);
sideBar = (DrawerLayout) findViewById(R.id.sqliteLayout);
sideBarToggle = new ActionBarDrawerToggle(this, sideBar, R.string.sideBarOpen, R.string.sideBarClose);
sideBar.addDrawerListener(sideBarToggle);
sideBarToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);

Call setSupportActionBar(actionToolbar); before you set up your ActionBarDrawerToggle.
ActionBarDrawerToggle uses getSupportActionBar() under the hood, so all the work it is doing is wiped out when you call setSupportActionBar afterwards.

Make sure you have added:
actionBar.setDisplayHomeAsUpEnabled(true);
Not this one:
getSupportActionBar().setHomeAsUpIndicator(true);

How to load the drawer as in the image on a button click

I have an app that displays the default activity as:
When clicked the hamburger icon opens left main navigation drawer as:
And when clicked the FILTER button opens another drawer from the right as:
I know how the left navigation drawer is displayed (all java codes and layouts)
What is the code for displaying the drawer that is opening from the right ?
and also i wanna know, how the on click listener is set up even if the FILTER button is outside the toolbar ?
Can anyone help?

Just change the value of tools:openDrawer to end (i.e tools:openDrawer="end"), also add android:layout_gravity="end" in <android.support.design.widget.NavigationView>. Here's the solution.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
//Add this piece of code
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(drawer.isDrawerOpen(Gravity.RIGHT)){
drawer.closeDrawer(Gravity.RIGHT);
}else{
drawer.openDrawer(Gravity.RIGHT);
}
}
});
}

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);

}
}'

I would rewrite the app using API level 8. Level 8 goes on 95% of android devices. Also you can check your manifest and try to set your "miniSdk to 8" "targetSdk to 18" and "maxSdk to 24".
You want to search your manifest for something that looks like this
<uses-sdk android:minSdkVersion="integer"
android:targetSdkVersion="integer"
android:maxSdkVersion="integer" />

Navigation drawer: unable to show the back icon instead of hamburger icon on the toolbar in the children activities

I am using the DrawerLayout with the v7 Toolbar, and I want to show the hamburger icon in the main activity, and the back icon in the children activities.
I am not able to do that, the hamburger icon is always shown, also in the children activities.
I already searched on so without success (if I lost some usefull questions I apologize).
This is the Android manifest:
<activity android:name=".activities.MainActivity"></activity>
<activity
android:name=".activities.BuyActivity"
android:windowSoftInputMode="adjustResize"
android:parentActivityName=".activities.MainActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".activities.MainActivity" />
</activity>
This is the activity code (the BaseActivity is the superclass for the parent and children activities):
public class BaseActivity extends AppCompatActivity implements NavigationDrawerFragment.NavigationDrawerCallbacks {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_buy);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.app_name, R.string.app_name);
drawerLayout.addDrawerListener(actionBarDrawerToggle);
getSupportActionBar().setDisplayShowTitleEnabled(false);
mNavigationDrawerFragment = (NavigationDrawerFragment)
getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
}
}
This is the part of the layout of the toolbar:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:background="?attr/colorPrimary">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/txtTitle"
android:textColor="#android:color/white"
android:text="#string/title_buy"
android:textAppearance="#android:style/TextAppearance.Large" />
<ImageView
android:layout_width="#dimen/toolbar_image"
android:layout_height="#dimen/toolbar_image"
android:src="#drawable/done"
android:background="#drawable/bg_border_white_l"
android:layout_marginRight="#dimen/toolbar_margin_right"
android:layout_marginEnd="#dimen/toolbar_margin_right"
android:contentDescription="#string/app_name"
android:layout_gravity="end"
android:id="#+id/imgDone" />
</android.support.v7.widget.Toolbar>
I tried:
checked to import the correct android.support.v7.app.ActionBarDrawerToggle
I don't know what I am doing wrong.

In child activities you should not add ActionBarDrawerToggle, as this is what sets a hamburger icon. Move the ActionBarDrawerToggle to the main activity instead.

Different toolbar for fragments and Navigation Drawer

Please, explain to me... I have Navigation Drawer in my Activity and it syncs with Toolbar (like ActionBar). Activity has few fragments and in different fragments I need to use different AppBar modes (parallax in one, simple in another). So, I think that I should set CoordinatorLayout in each frament with AppBar and content.
But how I can replace last toolbar on new to save synchronization with Drawer? Or it's wrong way and I need make it some else?

Not sure if my approach is good, but I tried to add this public method to my activity:
public void setToolbar(Toolbar toolbar) {
if(toolbar != null) {
setSupportActionBar(toolbar);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
} else {
drawer.setDrawerListener(null);
}
}
and I added this in all fragments:
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
((MainActivity)getActivity()).setToolbar(toolbar);
}
#Override
public void onDestroyView() {
((MainActivity)getActivity()).setToolbar(null);
super.onDestroyView();
}
It's working fine, but I'm not sure if it may cause a memory leak or any other performance issue. Maybe someone can help with it?

You can access main DrawerLayout from each Fragment just like the following code:
AppCompatActivity actionBar = (AppCompatActivity) getActivity();
actionBar.setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) actionBar.findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
getActivity(), drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();

If you want to use appbar(toolbar) that you specified in navigation drawer in different fragments with, for example different options menu items, you could make a public method in Main Activity where you specified your navigation drawer logic.
public void setToolbar(Toolbar toolbar, String title){
AppCompatActivity actionBar = this;
actionBar.setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout)actionBar.findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toogle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.drawer_open, R.string.drawer_close);
drawer.addDrawerListener(toogle);
toogle.setDrawerIndicatorEnabled(true);
toogle.syncState();
if(toolbar != null)
toolbar.setTitle(title);
}
Now you can use this method in your fragments to access the main toolbar and override it with your custom title, options menu...
You can do this by creating a new toolbar variable in your fragment and then inflate it in onCreateView() method like this
toolbarFragment = (Toolbar)getActivity().findViewById(R.id.toolbar);
R.id.toolbar is the id of a toolbar that you specified in your layout file and it is the same id that you used in your main activity for the main toolbar.
Now you can call the method setToolbar(Toolbar toolbar, String title) in fragment like this
((MainActivity)getActivity()).setToolbar(toolbarFragment, "Some title");
If you want to use options menu for this fragment you have to call
setHasOptionsMenu(true);
in fragments onCreate() or onCreateView() methods. After that you can override method onCreateOptionsMenu() like this
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.custom_menu1, menu);
}
You can repeat this procedure for other fragments in your navigation drawer as well. Although it worked for me, I don't know if this violates activities or fragments lifecycle or causes memory leeks.

I have the same problem. I wanted to add CollapsingToolbar only in the main fragment. By removing the toolbar from Activity, I lost the hamburger button and the connection to drawerLayout. To solve this problem, I didn't delete the Toolbar in activity and made it transparent. And for each fragment, I created my own custom toolbar. In the end, I have a hamburger button linked to the Drawer and a well-functioning CollapsingToolbar. I know it's a crutch. But I couldn't find another way
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".activity.MainActivity">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.appbar.AppBarLayout

android:theme="#style/AppTheme.AppBarOverlay"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</com.google.android.material.appbar.AppBarLayout>
<include
android:id="#+id/include"
layout="#layout/content_main"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
To make the AppBar completely invisible, I added
AppBarLayout appBarLayout = findViewById(R.id.appbar);
appBarLayout.setOutlineProvider(null);
This works for Android with sdk version 21.

If you are using DrawerLayout and NavigationView for your navigation drawer, best solution according to me would be to use individual DrawerLayout for each of the fragment layouts and use the AppBarLayout in the body of the DrawerLayout differently for each of the fragments.
