When I try to view activity_home.xml as a design it will not showing left drawer but when I install the app on device it will show the left drawer on click but when I click on any time it will not showing check able box and not working.

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.

OnClick Event for Navigation Drawer items

I have a trouble with my app. I want to make an app that has WebView and will change the URL when I click one of the items on the navigation drawer. For example:
Facebook
Twitter
Github
and so on. But I couldn't implement the onClick event. I am new in Android development. Thanks in advance.
This is my Java File
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
private Toolbar mToolBar;
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mToolBar = (Toolbar) findViewById(R.id.nav_action_bar);
setSupportActionBar(mToolBar);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mToggle = new ActionBarDrawerToggle(this,mDrawerLayout,R.string.open,R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
webView = (WebView) findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.loadUrl("https://www.facebook.com/groups/276912206003690/");
webView.setWebViewClient(new WebViewClient());
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mToggle.onOptionsItemSelected(item)){
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public void onBackPressed() {
if(webView.canGoBack()){
webView.goBack();
}else{
super.onBackPressed();
}
}
}
This my Main_activity.xml

Your MainActivity needs to implement NavigationView.OnNavigationItemSelectedListener and override onNavigationItemSelected
Create an instance of NavigationView(e.g. mNavigationView) and bind it to your view.
Set listener as mNavigationView.setNavigationItemSelectedListener(this);
Override onNavigationItemSelected()
Here's how that method looks:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.settings) {
//do something
} else if (id == R.id.log_out){
//do something
} else if (id == R.id.google) {
//do something
}
mDrawerLayout.closeDrawer(GravityCompat.START);
return true;
}

onClick event in navigation drawer

I have made a navigation drawer in Android in which I want to implement onClick for it. This is my main activity:
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle aToggle;
private Toolbar toolbar;
private RecyclerView recyclerView;
private RecyclerAdapter recyclerAdapter;
private RecyclerView.Adapter adapter;
private NavigationView navigationView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
aToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.navig, R.string.open, R.string.Close);
navigationView = (NavigationView) findViewById(R.id.nav_view);
mDrawerLayout.addDrawerListener(aToggle);
toolbar = (Toolbar) findViewById(R.id.nav_action);
toolbar.setNavigationIcon(R.drawable.navig);
setSupportActionBar(toolbar);
aToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
navigationView.setItemIconTintList(null);
recyclerView = (RecyclerView) findViewById(R.id.recycler);
recyclerAdapter = new RecyclerAdapter(getApplicationContext());
RecyclerView.LayoutManager layoutManager = new GridLayoutManager(this, 2);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(recyclerAdapter);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (aToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}}
This is my XML layout for the activity:
<?xml version="1.0" encoding="utf-8"?>

android:title="Remove Ads" />
<item
android:id="#+id/aboutus"
android:icon="#drawable/aboutus"
android:title="About Us" />
</group>
</menu>
The problem is I am not able to understand how to implement the onClick on the navigation drawer as it is populated by the list given by us not by any listView.
How can I implement onClick on the items of navigation drawer?

You need to add implements NavigationView.OnNavigationItemSelectedListener
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener
and add method
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
// Handle navigation view item clicks here.
switch (item.getItemId()) {
case R.id.nav_maths: {
//do somthing
break;
}
}
//close navigation drawer
mDrawerLayout.closeDrawer(GravityCompat.START);
return true;
}
method to set Listener
private void setNavigationViewListener() {
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
call method in onCreate()
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setNavigationViewListener()
}

Add NavigationItemSelectedListener event to nav_view
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
Implement your Activity with NavigationView.OnNavigationItemSelectedListener
and add this code for click item
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_camera) {
// Handle the camera action
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}

class MainActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val nav_view: NavigationView = findViewById(R.id.nav_view)
nav_view.setNavigationItemSelectedListener(this)
nav_view.bringToFront();
}
override fun onNavigationItemSelected(item: MenuItem): Boolean {
when(item.itemId){
R.id.miid_log_out -> Toast.makeText(this, "Working", Toast.LENGTH_SHORT).show()
}
return false
}
}

in your
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (aToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}}
add these lines:
switch (item.getItemId()) {
case R.id.nav_maths:
// your logic here.
return true;
case R.id.nav_physics:
//your logic here
return true;
default:
return super.onOptionsItemSelected(item);
}

Below code is for adding toggle to DrawerLayout
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);
And to add listener to Navigation menu items
implements NavigationView.OnNavigationItemSelectedListener
and override below method
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if(id == R.id. nav_maths){
//Handle your stuff here
}
}
Add below code to onCreate method
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);

Step-1: Extends the NavigationView.OnNavigationItemSelectedListener on your Activity
Step2:
Then there will show an error then override the method:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
return false;
}
get the Id with menuItem.getId() .And Perform Your Action as per your need.
final Step: Add This line in onCreate navigationView.setNavigationItemSelectedListener(this);
That's it.

binding.navigationView.setNavigationItemSelectedListener {
when(it.itemId){
R.id.book -> Toast.makeText(applicationContext, "Booked", Toast.LENGTH_SHORT).show()
}
true
}

fab=(FloatingActionButton)findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
}

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;
}

NavigationView: background color of pressed item alternates randomly on Jellybean

My app has two activities with a DrawerLayout and a NavigationView (android.support.design.widget.NavigationView).
I use an app theme with parent Theme.AppCompat.Light.DarkActionBar, and for my Lollipop emulator, there are no problems.
But for my Jellybean device and emulator, I have a very strange behaviour:
The background of the NavigationView items is sometimes rendered as light grey (which would be ok for me), sometimes as a light blue shade (I think it's the Theme Holo default).
For my "real" app, the grey tint would always appear on the first drawer and the blue tint always on the other one. At first I thought the difference may be due to some detail like the first uses an ActionBarDrawerToggle and the other one doesn't, so maybe I had to somehow set the android:listSelector for the second one only.
So I created a MCVE-like sample and noticed that both drawers show both tints now and then. Is this a bug or am I missing something?
What can I do to get rid of Theme Holo?
Screenshots:
By the way, I have the same random behaviour for the ActionButton background:
My code (~ 95% of it for those who like to run their own tests):
activity_main.xml just a 'Blank Activity' with a big "Hello World" at the center:

OtherActivity - the drawer is like a context menu and appears from the right without overlapping the ActionBar:

UPDATE (May 2016)
Meanwhile I've also tried setting my own background for the NavigationView items. The background is changed but on touching I still get a ripple for Lollipop and higher (which is ok) and unfortunately still the alternating effect on Jellybean, probably from some kind of list selector which I don't know how to manipulate.
UPDATE 2 (September 2016)
I installed a new version of Android Studio, am using the newest versions of build tools and all the libraries (24.0.2 respectively 24.2.0) and even ditched the ActionBar in favour of Toolbar. The last means I won't have to use the hack in Main to get the nav drawer to cover the ActionBar, so I'm not using a LayoutInflater in my code any more.
But still no luck :(
I'm pretty sure that this is a bug: the same code behaving differently from one app run to the next and the inconsistency between activities Main and Other during one and the same run.
