In android navigation menu, menu item is not clickable

I'm working on a menu navigation drawer , in that I'm not able to click items when I'm adding a constraint layout inside the drawer layout. But after removing that click, the menu item works fine. So please tell me how can I fix this issue.
here below is my activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout
tools:context=".MainActivity"
android:id="#+id/drawerlayout"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include layout="#layout/appbar">
</include>
<com.google.android.material.navigation.NavigationView
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:menu="#menu/navigationitem"
android:id="#+id/navigationview"
app:headerLayout="#layout/header_layout"
android:layout_gravity="start">
</com.google.android.material.navigation.NavigationView>
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test"
android:textColor="#color/white">
</TextView>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.drawerlayout.widget.DrawerLayout>
And here below is my mainactivity
public class MainActivity extends AppCompatActivity {
DrawerLayout drawerLayout;
Toolbar toolbar1;
NavigationView navigationView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
drawerLayout=findViewById(R.id.drawerlayout);
toolbar1=findViewById(R.id.tbar);
navigationView=findViewById(R.id.navigationview);
toolbar1.inflateMenu(R.menu.navigationitem);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar1,R.string.nav_open,R.string.nav_close);
drawerLayout.addDrawerListener(toggle);
toggle.syncState();
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
int id = item.getItemId();
if (id==R.id.profile){
Toast.makeText(MainActivity.this, "Profile", Toast.LENGTH_SHORT).show();
}
else if(id==R.id.contact){
Toast.makeText(MainActivity.this, "Contact", Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(MainActivity.this, "Logoutact", Toast.LENGTH_SHORT).show();
}
drawerLayout.closeDrawer(GravityCompat.START);
return true;
}
});
}
}
Now, How Can Solve This Problem?

How add custom navigation view in Android

I have created the layout as attached below, I haven't used any drawerlayout or navigation view. top bar is created using toolbar tag. Now I want to add a navigation view which will invoke once user clicks that hamburger icon. And it should be accessible from other activities as well

You should use the navigation drawer.
You can do this this by creating one common class named BaseActivity and put your code of navigation drawer in this class. and extend your classes/Activities with BaseActivity, where you want to show navigation drawer.
public class BaseActivity extends AppCompatActivity {
public Toolbar toolbar;
ActionBarDrawerToggle mDrawerToggle;
Context context;
private NavigationView navigationView;
private DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
protected boolean useToolbar() {
return true;
}
#Override
public void setContentView(int layoutResID) {
context = this;
DrawerLayout fullView = (DrawerLayout) getLayoutInflater().inflate(R.layout.drawer_main, null);
FrameLayout activityContainer = (FrameLayout) fullView.findViewById(R.id.frame);
getLayoutInflater().inflate(layoutResID, activityContainer, true);
super.setContentView(fullView);
toolbar = (Toolbar) fullView.findViewById(R.id.tool_bar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("");
toolbar.setTitle("");
this.getSupportActionBar().setElevation(0);
getSupportActionBar().setLogo(R.drawable.ic_arrahm);
// toolbar.setLogo(R.drawable.ic_main);
if (useToolbar()) {
setSupportActionBar(toolbar);
setTitle("Places Near Me");
} else {
toolbar.setVisibility(View.GONE);
}
//Initializing NavigationView
navigationView = (NavigationView) findViewById(R.id.navigation_view);
//Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
// This method will trigger on item Click of navigation menu
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Checking if the item is in checked state or not, if not make it in checked state
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
case R.id.edit_profile:
return true;
case R.id.change_password:
return true;
default:
Toast.makeText(getApplicationContext(), "Work in progress", Toast.LENGTH_SHORT).show();
return true;
}
}
});
// Initializing Drawer Layout and ActionBarToggle
drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
View header = navigationView.getHeaderView(0);
TextView tvName = (TextView) header.findViewById(R.id.name);
TextView tvEmail = (TextView) header.findViewById(R.id.email);
String name = Preferences.getDataFromStringPreferences(context,Constants.USER_DETAILS, Constants.USER_NAME);
if (name != null) {
tvName.setText(name);
}
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.openDrawer, R.string.closeDrawer) {
#Override
public void onDrawerClosed(View drawerView) {
// Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
//Setting the actionbarToggle to drawer layout
drawerLayout.setDrawerListener(actionBarDrawerToggle);
//calling sync state is necessay or else your hamburger icon wont show up
actionBarDrawerToggle.syncState();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
return super.onPrepareOptionsMenu(menu);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
return mDrawerToggle.onOptionsItemSelected(item);
}
}

I want to create both navigation drawer and bottom navigation in the same activity. I created XML design now I have to write java code for both. Bottom navigation is working perfectly but navigation item clicklistener is not working. I created fragments for navigation drawer and also for bottom navigation. When I click the items in navigation drawer it's not redirecting to respective fragment. The given clicklistener for navigation drawer is not at all working.

Solution:
Try the following steps to get it working:
Step1: Implement onNavigationItemSelected as shown below:
.... extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
Step2: Use the method generated by the interface as:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.your_drawer_item_id:
....
....
case R.id.your_drawer_item_id:
....
....
}
}
Step3: In your class declare a Global variable:
public NavigationView navigationView;
Step4: In your onCreate() initialize the variable as:
navigationView = (NavigationView) findViewById(R.id.your_nav_view);
Finally: Setup the navigationView:
navigationView.setNavigationItemSelectedListener(this);
That's it.
Hope it works.

Try it.

You can use on the same activity using a method that recive a MenuItem parameter like this:
private void myClickItem(MenuItem item){
switch (item.getItemId()) {
case R.id.bottom_home:
// DO SOMETHING
break;
case R.id.drawer_main:
// DO SOMETHING
break;
}
}
Then, call like this:
BottomNavigationView bottomNavigationView = findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(item -> { // using lamda
myClickItem(item); //call here
return true;
});
NavigationView navigationView = findViewById(R.id.nv);
navigationView.setNavigationItemSelectedListener(item -> {
myClickItem(item); // call the same method here
drawerLayout.closeDrawers(); // bonus: hide navigation after click
return false;
});
You don't need to modify your xml res, it'll work fine.

Try by adding Toolbar to your ActionBarDrawerToggle.
mActionBarDrawerToggle = new ActionBarDrawerToggle(this,mDrawerLayout,toolbar,R.string.drawer_opened,R.string.drawer_closed)
{
#Override
public void onDrawerOpened(View drawerView) {
if (getSupportActionBar()!= null ) {
getSupportActionBar().setTitle(R.string.drawer_opened);
}
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
if (getSupportActionBar()!= null ) {
getSupportActionBar().setTitle(R.string.drawer_closed);
}
}
};
mDrawerLayout.setDrawerListener(mActionBarDrawerToggle);

try changing your xml file to
<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">
<LinearLayout
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?android:attr/actionBarSize" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world" />
</LinearLayout>
<ListView
android:id="#+id/drawerList"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start" />
</android.support.v4.widget.DrawerLayout>
Hope it helps
