Just Put your NavigationView bottom of all layout inside DrawerLayout
Like this
<android.support.v4.widget.DrawerLayout
xmlns:android="https://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"
tools:openDrawer="start">
---- Here is your layouts
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>

Try adding the logic manually:
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
drawerLayout.openDrawer(GravityCompat.START);
}
});

Please replace RelativeLayout as parent layout to DrawerLayout
<androidx.drawerlayout.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="match_parent"
android:layout_height="match_parent" />

android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"/>
..
..
</androidx.drawerlayout.widget.DrawerLayout>
In MainActivity
DrawerLayout drawer;
ActionBarDrawerToggle toggle;
drawer = findViewById(R.id.drawer_layout);
toggle = new ActionBarDrawerToggle(
this, drawer, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
and add This Functionality on menu button click to open and close
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
drawer.openDrawer(GravityCompat.START);
}

ActionBarDrawerToggle isn't working till the time i manually swipe right to open the navigation drawer. After this, it responds perfectly

Problem:
When I open my application and click on the ActionBarDrawerToggle, it doesn't open the navigation drawer. However, when i swipe right and then open and close the navigation drawer, after this the ActionBarDrawerToggle repsonds perfectly fine, like it should, by opening the drawer.
My HomeScreen.java
public class HomeScreen extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
private Toolbar toolbar;
private DrawerLayout drawerLayout;
private NavigationView navigationView;
private ActionBarDrawerToggle toggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home_screen);
instantiateViews();
setSupportActionBar(toolbar);
navigationView.setNavigationItemSelectedListener(this);
toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
drawerLayout.addDrawerListener(toggle);
toggle.syncState();
}
public void instantiateViews(){
toolbar = findViewById(R.id.drawer_menu_toolbar);
drawerLayout = findViewById(R.id.home_screen_main_drawer_layout);
navigationView = findViewById(R.id.home_screen_navigation_view);
}
#Override
public void onBackPressed(){
if(drawerLayout.isDrawerOpen(GravityCompat.START)){
drawerLayout.closeDrawer(GravityCompat.START);
}else {
super.onBackPressed();
}
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()){
case R.id.nav_home:
break;
case R.id.nav_account:
break;
case R.id.nav_share:
break;
case R.id.nav_logout:
session.logoutUser();
break;
}
drawerLayout.closeDrawer(GravityCompat.START);
return true;
}
}
I have tried everything from the following thread: Navigation Drawer ActionBar button not working even though for that person the ActionBarDrawerToggle wasn't working under all circumstances but mine isn't working till the time navigation drawer is opened. After that mine works perfectly
What I have tried doing:
1.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (toggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
2.
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
toggle.syncState();
3.
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
drawerLayout.openDrawer(GravityCompat.START);
}
});
None of these work for me

Try this, or Try to take out your Toolbar from Relative Layout.
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">

I have done some minor modification in your layout i hope it will help you.

Navigation drawer is not open when click on ImageView

I want to implement navigation drawer, it's working well when i swipe but it's not open when click on ImageView my code is look like below
MainActivity
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
imgMenu = (ImageView) findViewById(R.id.imgMenu);
imgMenu.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mDrawerLayout.isDrawerOpen(GravityCompat.START);
}
});

android:id="#+id/drawer_layout"

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_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
app_bar_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<include layout="#layout/home_details" />
</android.support.design.widget.CoordinatorLayout>
In home_details i have took
<ImageView
android:id="#+id/imgMenu"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="#dimen/padding_10"
android:src="#drawable/ic_menu" />
isDrawerOpen only checks if the drawer is opened or not. Use openDrawer method instead.
mDrawerLayout.isDrawerOpen(GravityCompat.START) actually tells you the state of your drawer and does not change the state of the drawer.
To change the state of the drawer, replace that line with mDrawerLayout.openDrawer(GravityCompat.START).
try this one...
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
imgMenu = (ImageView) findViewById(R.id.imgMenu);
imgMenu.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mDrawerLayout.openDrawer(GravityCompat.START);
}
});

How to use Butterknife in Combination with a navigation header?

I bind some Views with Butterknife but it doesn't work somehow.
The Exception i got is
java.lang.IllegalStateException: Required view 'full_name_nav'
which basically says that he can't find the view. So i think i am binding at the wrong position, but i don't know where i should do it correctly. I am including the Navigation Header Layout in the NavigationView and binding these views in my oncreate method.
My Code:
XML Layout of the Activity:
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"

android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main" <!-- Including the Navigation Header here-->
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
XML Layout of the Navigation Header
<?xml version="1.0" encoding="utf-8"?>

android:theme="#style/ThemeOverlay.AppCompat.Dark">
<ImageView

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_height="wrap_content" />
<TextView
android:id="#+id/motorcycle_model_nav"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
My Main Activity where i actually bind the views:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#BindView(R.id.full_name_nav)
TextView navigationName;
#BindView(R.id.motorcycle_model_nav)
TextView navigaitonMotorcycle;
#BindView(R.id.user_name_nav)
TextView navigationUsername;
SharedPreferences prefs;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
prefs = this.getSharedPreferences(
"package", Context.MODE_PRIVATE);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ButterKnife.bind(this); // Calling ButterKnife here
setNavInfo();
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){
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
I implemented the Viewbinding in the OnCreateOptionsMenu, now it works.

same navigation drawer in different activities, toolbar error

I'm trying to develop an app with multiple activities and the same navigation drawer and toolbar.
I've created a BaseActivity for initialization of drawer and other activities extend it, but I have problems with toolbar, in particular when using setSupportActionBar(toolbar).
How can I fix this problem?

drawer.closeDrawer(GravityCompat.START);
return true;

You can't use same Navigation Drawer and Toolbar with different Activities.
If you want different screens with the same components, you have to use Fragments with one Activity, for example FragmentActivity.

Android DrawerLayout not responding to button click event

I have a DrawerLayout component in my activity, but I'm not using ActionBar.
This is my main_activity.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white">
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/mainContainer"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
<ListView
android:id="#+id/drawer"
android:layout_width="650dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/white"
android:divider="#null"
android:choiceMode="singleChoice"
android:visibility="gone"/>
</android.support.v4.widget.DrawerLayout>
<ImageButton
android:id="#+id/categories_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_margin="20dp"
android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:background="#drawable/button_category"/>
In my MainActivity I try to open/close the DrawerLayout by clicking on my Button.
Here is my Activity:
public class MainActivity extends Activity {
private ImageButton categoriesButton;
private DrawerLayout drawerLayout;
private ListView drawerMenu;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
categoriesButton = (ImageButton)findViewById(R.id.categories_button);
categoriesButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(drawerLayout.isDrawerOpen(drawerMenu)) {
drawerLayout.closeDrawer(drawerMenu);
}else {
drawerLayout.openDrawer(drawerMenu);
}
}
});
drawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
drawerMenu = (ListView) findViewById(R.id.drawer);
MyAdapter myAdapter = new MyAdapter(context, getCategories());
drawerMenu.setAdapter(myAdapter);
}
}
When I click the Button the first time it does not respond, but after I open the DrawerLayout manually it works perfect.
Does anybody know what is wrong here?
Thanks!
I found the solution! In the xml, the Listview visibility needs to be set to visible. It was set to gone (I took this code from the oficial documentation).
<ListView
android:id="#+id/drawer"
android:layout_width="650dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/white"
android:divider="#null"
android:choiceMode="singleChoice"
android:visibility="visible"/>
Anyway now it works. Thanks for your help!
