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:background="#android:color/white"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_home_navigation"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<com.google.android.material.navigation.NavigationView
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);
}

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.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_main"
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" <!-- 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"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:background="#drawable/side_nav_bar"
android:gravity="bottom"
android:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:theme="#style/ThemeOverlay.AppCompat.Dark">
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="#dimen/nav_header_vertical_spacing"
app:srcCompat="#android:drawable/sym_def_app_icon" />
<TextView
android:id="#+id/user_name_nav"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="#dimen/nav_header_vertical_spacing"
android:textAppearance="#style/TextAppearance.AppCompat.Body1" />
<TextView
android:id="#+id/full_name_nav"
android:layout_width="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.

Open Navigation Drawer onCreate

I'm currently trying to implement a Navigation Drawer into my Application. For that i want the Drawer to be opened when the activity is started. This is my onCreate:
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_master);
isInLandscapeMode = getResources().getBoolean(R.bool.isInLandscape);
if (!isInLandscapeMode)
{
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.ic_drawer, R.string.date, R.string.applicationName)
{
/**
* 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);
drawerView.bringToFront();
drawerView.requestLayout();
}
};
// Set the drawer toggle as the DrawerListener
drawerLayout.setDrawerListener(drawerToggle);
drawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
}
drawerLayout.openDrawer(Gravity.START);
}
The Drawer is opening as it should but if i try to click one of my list entries it closes. If I open it manually afterwards everything is working perfectly. Do I have to set the focus on my drawerLayout somehow? I have tried several things but nothing seems to work.
UPDATE
Finally found my error:
I had the following code in my layout xml file:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/list_container"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#f1f1f1"
android:orientation="horizontal" >
</LinearLayout>
<FrameLayout
android:id="#+id/detail_container"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal" >
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
</FrameLayout>
The main content view(detail_container) must be the first child in the navigation drawer thought. So i changed it to this:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/detail_container"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal" >
</FrameLayout>
<LinearLayout
android:id="#+id/list_container"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#f1f1f1"
android:orientation="horizontal" >
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</FrameLayout>
And it worked.

Use drawer.openDrawer(Gravity.LEFT);

After you find your drawer layout and Data(list or expandable list) then put
drawerLayout.openDrawer("Name of Data Contained By Drawer");

Toolbar buttons don't respond to touch when a Navigation Drawer is open

I'm working on a material design version of my app using the appcompat v7 libraries, and I've hit an issue with the navigation drawer. When it opens, buttons in the material design toolbar cease to function - any touch outside the navigation drawer just closes the drawer. A following is a gif of what I mean
Here is the xml layout I'm using for the activity:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/action_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:elevation="4dp"
/>
<FrameLayout
android:id="#+id/note_list_container"
android:layout_marginTop="?attr/actionBarSize"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<net.rymate.notes.ui.FloatingActionButton
android:id="#+id/fabbutton"
android:layout_width="72dp"
android:layout_height="72dp"
android:layout_gravity="bottom|right"
android:layout_marginBottom="16dp"
android:layout_marginRight="16dp" />
</FrameLayout>
<!-- The navigation drawer -->
<LinearLayout
android:id="#+id/left_drawer"
android:layout_width="300dp"
android:layout_marginTop="?attr/actionBarSize"
android:layout_height="match_parent"
android:layout_gravity="start"
android:orientation="vertical">
<ListView
android:id="#+id/cat_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="?catBackColour" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
And here is the onCreate code that initialises the drawer and the toolbar.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ROBOTO_LIGHT = Typeface.createFromAsset(this.getAssets(), "Roboto-Light.ttf");
ROBOTO_LIGHT_ITALICS = Typeface.createFromAsset(this.getAssets(), "Roboto-LightItalic.ttf");
setContentView(R.layout.activity_notes);
if (findViewById(R.id.note_container) != null) {
// The detail container view will be present only in the
// large-screen layouts (res/values-large and
// res/values-sw600dp). If this view is present, then the
// activity should be in two-pane mode.
mTwoPane = true;
// In two-pane mode, list items should be given the
// 'activated' state when touched.
FragmentManager fm = getSupportFragmentManager();
//list.setActivateOnItemClick(true);
}
if (!mTwoPane) {
final FloatingActionButton mFab = (FloatingActionButton) findViewById(R.id.fabbutton);
mFab.init(Color.parseColor("#1e90ff"));
mFab.setFabDrawable(getResources().getDrawable(R.drawable.ic_action_new));
mFab.showFab();
mFab.setOnClickListener(this);
list = new NotesListFragment(mFab);
} else {
list = new NotesListFragment();
}
Toolbar toolbar = (Toolbar) findViewById(R.id.action_toolbar);
setSupportActionBar(toolbar);
getSupportFragmentManager().beginTransaction()
.replace(R.id.note_list_container, list)
.commit();
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); // the layout
mDrawerLinear = (LinearLayout) findViewById(R.id.left_drawer);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerLayout.setScrimColor(getResources().getColor(android.R.color.transparent));
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
toolbar, /* toolbar */
R.string.drawer_open, /* "open drawer" description */
R.string.drawer_close /* "close drawer" description */
) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle("Rymate Notes");
supportInvalidateOptionsMenu();
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setTitle("Categories");
supportInvalidateOptionsMenu();
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
pref = getSharedPreferences("rymatenotesprefs", MODE_PRIVATE);
mDrawerList = (ListView) findViewById(R.id.cat_list);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
mDbHelper = new NotesDbAdapter(this);
mDbHelper.open();
if (mDbHelper.fetchAllNotes().getCount() == 0) {
IntroFragment fragment = new IntroFragment();
getSupportFragmentManager().beginTransaction()
.replace(R.id.note_list_container, fragment)
.commit();
}
getCategories(); // calls a function which populates the listview
}
Is there a way to possibly fix this?

Seems that touch event is stolen by the shadow of the drawer, i.e DrawerLayout keeps intercepting the touch events, because Toolbar is part of the content view, unlike the ActionBar being on top of the decor view.
Possible work around is intercepting the touch event:
If it s between 0 (top) and Toolbar height (bottom), dispatch the event directly to the Toolbar object. Otherwise keep the normal behaviour.
Is same case for drawer toggle clicks?

Turns out Nikola Despotoski had the right idea - the touch event was stolen by the DrawerLayout. However instead of intercepting the touch event I just adjusted the activity layout like so:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<android.support.v7.widget.Toolbar
android:id="#+id/action_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize" >
<!-- The main content view -->
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/note_list_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<net.rymate.notes.ui.FloatingActionButton
android:id="#+id/fabbutton"
android:layout_width="72dp"
android:layout_height="72dp"
android:layout_gravity="bottom|right"
android:layout_marginBottom="16dp"
android:layout_marginRight="16dp" />
</FrameLayout>
<!-- The navigation drawer -->
<LinearLayout
android:id="#+id/left_drawer"
android:layout_width="300dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:orientation="vertical">
<ListView
android:id="#+id/cat_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?catBackColour"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</FrameLayout>
This has the intended effect of allowing touch events to be registered by the Toolbar rather than the DrawerLayout.

Navigation Drawer's click event not working

This is my layout . I have a Navigation Drawer and a button in the activity buttons Click event is working but the Click event for Drawer is not working.
<android.support.v4.widget.Drawer Layout

</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
The code i have implemented:
public class MainActivity extends Activity {
private String[] drawerListViewItems;
private DrawerLayout drawerLayout;
private ListView drawerListView;
private ActionBarDrawerToggle actionBarDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// get list items from strings.xml
drawerListViewItems = getResources().getStringArray(R.array.items);
// get ListView defined in activity_main.xml
drawerListView = (ListView) findViewById(R.id.left_drawer);
// Set the adapter for the list view
drawerListView.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_listview_item, drawerListViewItems));
// 2. App Icon
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
// 2.1 create ActionBarDrawerToggle
actionBarDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
drawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description */
R.string.drawer_close /* "close drawer" description */
);
// 2.2 Set actionBarDrawerToggle as the DrawerListener
drawerLayout.setDrawerListener(actionBarDrawerToggle);
// 2.3 enable and show "up" arrow
getActionBar().setDisplayHomeAsUpEnabled(true);
// just styling option
// drawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
drawerListView.setOnItemClickListener(new DrawerItemClickListener());
Button btn = (Button)findViewById(R.id.button1);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_SHORT).show();
}
});
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
actionBarDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// call ActionBarDrawerToggle.onOptionsItemSelected(), if it returns true
// then it has handled the app icon touch event
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MainActivity.this, ((TextView)view).getText(), Toast.LENGTH_LONG).show();
drawerLayout.closeDrawer(drawerListView);
}
}
}

In XML layout You have provided following attribute to Button tag
android:onClick="actionbtn"
This means method actionbtn will be invoked when user will click Button.
Create method called actionbtn under MainActivity like below with parameter as object of View class.
public void actionbtn(View view){
<< Put your code for drawer action here
drawerLayout.openDrawer(drawerListView)>>;
Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_SHORT).show();
}
Please note that I am not sure about code to put in method, but creating above method in MainActivity class will solve your issue.
Update -
Please try using following XML layout
<android.support.v4.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"
tools:context=".MainActivity" >
<!-- The main content view -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#e5e5e5"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
>
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"

android:text="Button" />
</RelativeLayout>
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"

android:paddingLeft="15dp"
android:paddingRight="15dp" />
</android.support.v4.widget.DrawerLayout>

public void onDrawerOpened(View drawerView) {
drawerListView.bringToFront();}

Your java code is perfect. Problem here is with your xml file.
You need to remove this part from android.support.v4.widget.DrawerLayout of the xml code and try then it'll run like a champ.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Try This
Xml:-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relative"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!--
As the main content view, the view below consumes the entire
space available using match_parent in both dimensions.
-->
