How can I close an android DrawerLayout when touched outside of it?

I have created a DrawerLayout and it works fine. But I want it to close when the user touches the background. This can be implemented with a DrawerLayout with listView but here i'm using a NavigationView. So is there a way to accomplish this?
Here is the menu layout for the NavigationView
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/home" android:title="Home Parent" android:icon="#drawable/ic_home_black"/>
<item android:id="#+id/send" android:title="Send" android:icon="#drawable/ic_send_black"/>
<item android:id="#+id/add" android:title="Add" android:icon="#drawable/ic_add_black"/>
</menu>
Here is the java code
public class ParentActivity extends AppCompatActivity {
private NavigationView mNavigationView;
private User mCurrentUser;
private UserLocalStore mUserLocalStore;
private CircleImageView mProfilePic;
private TextView mProfileName;
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_parent);
mUserLocalStore = new UserLocalStore(this);
mCurrentUser = mUserLocalStore.getUserDetails();
mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer);
mToggle = new ActionBarDrawerToggle(this,mDrawerLayout,R.string.open,R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mNavigationView = (NavigationView)findViewById(R.id.navigationView);
setNavigationViewMenu(mCurrentUser.userType);
mProfileName = (TextView) mNavigationView.getHeaderView(0).findViewById(R.id.profileName);
mProfileName.setText(mCurrentUser.getName());
mProfilePic = (CircleImageView) mNavigationView.getHeaderView(0).findViewById(R.id.circleImageProfile);
Picasso.with(this).load("https://www.sonypark360.net/wp-content/uploads/2017/08/profile-pictures.png").into(mProfilePic);
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
mDrawerLayout.closeDrawers();
return false;
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(mToggle.onOptionsItemSelected(item)){
return true;
}
return super.onOptionsItemSelected(item);
}
private void setNavigationViewMenu(String userType) {
switch (userType){
case "s":
mNavigationView.inflateMenu(R.menu.menu_student_navigation_drawer);
break;
case "pa":
mNavigationView.inflateMenu(R.menu.menu_parent_navigation_drawer);
break;
case "pr":
mNavigationView.inflateMenu(R.menu.menu_principal_navigation_drawer);
break;
case "t":
mNavigationView.inflateMenu(R.menu.menu_teacher_navigation_drawer);
break;
}
}
}
Here is the DrawerLayout code
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.mlpj.www.morascorpions.ParentActivity">
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/navigation_header_layout"
>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
I have also looked into this question, but it does not solve my problem

Try this
#Override
public boolean dispatchTouchEvent(MotionEvent ev) {
Rect viewRect = new Rect();
mNavigationView.getGlobalVisibleRect(viewRect);
if (!viewRect.contains((int) ev.getRawX(), (int) ev.getRawY())) {
//hide your navigation view here.
}
return super.dispatchTouchEvent(ev);;
}

Android menu with ActionBarDrawerToggle

I have a simple task:
Create a menu with few items which opens on a toggle action bar button.
My activity_main is:
<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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.mt.gmtelandroid.MainActivity"
android:id="#+id/drawer_layout">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
<android.support.design.widget.NavigationView
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:menu="#menu/navigation_menu"
android:layout_gravity="start"
app:headerLayout="#layout/navigation_header"
>
</android.support.design.widget.NavigationView>
and navigation menu
<menu xmlns:android="http://schemas.android.com/apk/res/android" android:id="#+id/meni1" >
<item android:id="#+id/navhome"
android:title="Home"
android:icon="#mipmap/ic_home_black_24dp"
>
</item>
<item android:id="#+id/navtasks" android:title="Zadaci"
android:icon="#mipmap/ic_drive_eta_black_24dp"
></item>
<item android:id="#+id/navlogout" android:title="Odjava"
android:icon="#mipmap/ic_close_black_24dp">
</item>
<item android:id="#+id/myname" android:title="Moj Nalog"
android:icon="#mipmap/ic_account_circle_black_24dp">
</item>
Main activity is
public class MainActivity extends AppCompatActivity
{
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mtogle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
mtogle = new ActionBarDrawerToggle(this, mDrawerLayout,R.string.open_menu, R.string.close_menu);
mDrawerLayout.addDrawerListener(mtogle);
mtogle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mtogle.onOptionsItemSelected(item))
{
return true;
}
return super.onOptionsItemSelected(item);
}
}
I don't know how to add a listener onMenuItemClick so I can handle what happens when a user clicks on a menu item.
I have tried adding some code to onOptionsItemSelected method, but when I was debuging it I found out that this method is only called on toggle buton click, not on menu item click!?

You have to implement the callbacks for NavigationView.OnNavigationItemSelectedListener in Activity as below,
public class HomeActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener
than handle click event of NavigationView like below code
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Intent i;
if (id == R.id.navhome) {
// perform your action here
} else if (id == R.id.navtasks) {
// perform your action here
} else if (id == R.id.navlogout) {
// perform your action here
}else if (id == R.id.myname) {
// perform your action here
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}

Try to add:
callback implements NavigationView.OnNavigationItemSelectedListener,
It will override onNavigationItemSelected(MenuItem item) {... }. You can put your click code here by item.getItemId().
I hope this helps you.

Update These lines of code works for me.. after update clean and rebuild Project.
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.bringToFront();

Here is a simple solution to address this issue. You can just link your HomeActivity methods to the menu items (whichever you want to). Now just create your methods and go to the menu layout. In the menu layout just add the android:onClick inside the item tag and put the particular method name inside it. And you are done. Let me know if this was useful.

Navigation drawer, listen to item clicked events

I have this menu layout "navigation_menu.xml":
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/item1"
android:title="#string/item1"/>
<item
android:id="#+id/item2"
android:title="#string/item2"/>
<item
android:id="#+id/item3"
android:title="#string/item3"/>
</menu>
My main activity layout "activity_main.xml" is this:
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".MainActivity">
<android.support.design.widget.NavigationView
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:menu="#menu/navigation_menu"
android:layout_gravity="start">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
And this is the Java code of the main activity where I initialize the drawer:
private DrawerLayout drawer_layout;
private ActionBarDrawerToggle toggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
// ...
drawer_layout = (DrawerLayout)findViewById(R.id.drawer_layout);
toggle = new ActionBarDrawerToggle(this, drawer_layout, R
.string.open_drawer, R.string.close_drawer);
drawer_layout.addDrawerListener(toggle);
toggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// ...
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (toggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
The drawer opens and closes correctly, but I don't know how to do something when an item is clicked, for example showing a log.
Does anyone know?
Thanks

Use onNavigationItemSelected() method to handle Navigation Drawer Item Click. See Below Code.
private NavigationView mNavigationView;
#Override
protected void onCreate(Bundle savedInstanceState)
{
// ...
mNavigationView = (NavigationView) findViewById(R.id.nav_view);
mNavigationView.setNavigationItemSelectedListener(this);// you need to set Listener.
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item)
{
// mDrawer.closeDrawer(GravityCompat.START);
switch (item.getItemId()) {
case R.id.item1: {
}
break;
case R.id.item2: {
}
break;
case R.id.item3: {
}
break;
}
return true;
}

Navigation Drawer stops working after implementing MaterialSearchView

My main activity consists of a navigation drawer and switching between fragments was working fine. Now i tried to implement Material Searchview using this library which requires the toolbar to be set last inside the xml file. So now my serachview is working fine but onNavigationItemSelected stops working and i cant switch between fragments. If inside the xml i write navigation drawer below the toolbar navigation starts working again but searchview stops working. Please help me.

I think you forgot to add actionviewclass
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_search"
android:title="Search"
app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="com.miguelcatalan.materialsearchview.MaterialSearchView" />
