Navigation item's title disappeared when clicked - android

I have created drawer with navigation view. I have Navigation item's on which I am calling other activities.
The issue is when I click on navigation item, the other activity launches,and if I come back to main activity and open a drawer the clicked navigation item's title is disappeared only I can see the icon of the item.
code:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setNavigationIcon(R.drawable.menu_icon);
setSupportActionBar(toolbar);
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, mDrawer , toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
mDrawer .addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.setItemIconTintList(null);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_list) {
startActivity(new Intent(MainActivity.this, LaunchVenueServiceActivity.class));
// Handle the camera action
}
else if (id == R.id.nav_dashboard) {
startActivity(new Intent(MainActivity.this, MainActivity.class));
}
else if (id == R.id.nav_config)
{
startActivity(new Intent(MainActivity.this,LaunchYourServiceStep2.class));
}
else if (id == R.id.nav_chat) {
} else if (id == R.id.nav_notes) {
startActivity(new Intent(MainActivity.this,NotesActivity.class));
} else if (id == R.id.nav_user_guide) {
}
else if(id == R.id.nav_log_out)
{
SharedPreferences.Editor editor = getSharedPreferences("username",MODE_PRIVATE).edit();
editor.remove("UserUsername");
editor.commit();
Intent intent1 = new Intent(MainActivity.this,LoginActivity.class);
intent1.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
finish();
startActivity(intent1);
}
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawer.closeDrawer(GravityCompat.START);
return true;
}
}
What can be the reason for this?? Can anyone help please? Thank you..

Got the solution.. Just tried to change the color of navigation item's text and it worked. Don't know why and how..
navigationView.setItemTextColor(ColorStateList.valueOf(Color.BLACK));

That may appear if you changed style of your layout in manifest. Check if you have defined all items from default style such as color especially.

Navigation drawer items click is not working on other activities

I'm trying to click on navigation drawer items but not working.
I made a NavigationDrawerActivity (by default: creating new project) and an AriesActivity (new activity). When I go with NavigationDrawerActivity, item click works. But when i go with AriesActivity, item clicks are not working.
Here I included drawer icon on AriesActivity, clicking on icon navigation drawer opens but item clicks are not working.
So the main question is How to handle clicks over navigation items on other activities by including drawer on other activities?
Here's my AriesActivity code
public class AriesActivity extends AppCompatActivity {
Toolbar mtoolbar;
private DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_aries);
//setting TOOLBAR on this activity(page)
mtoolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mtoolbar);
Objects.requireNonNull(getSupportActionBar()).setTitle(null);
//setting DRAWER on this activity(page)
drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, mtoolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.addDrawerListener(toggle);
toggle.syncState();
}
}
You have to override this method (onNavigationItemSelected) Example :
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_gallery) {
startActivity(new Intent(Activity1.this, Activity2.class));
finish();
} else if (id == R.id.nav_slideshow) {
startActivity(new Intent(Activity2.this, Activity1.class));
finish();
} 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;
}

Why menu items in android studio don't work on click?

I'm developing a project on android and completely new to this. I had made a drawer menu with some of menu items. Now when i want to put another activity on click from menu items, the drawer closes automatically, it doesn't work. Here
private DrawerLayout mdrawerLayout;
private ActionBarDrawerToggle mdrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mdrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
mdrawerToggle = new ActionBarDrawerToggle(this, mdrawerLayout, R.string.open, R.string.close);
mdrawerLayout.addDrawerListener(mdrawerToggle);
mdrawerToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mdrawerToggle.onOptionsItemSelected(item)) {
return true;
}
int id = item.getItemId();
if(id == R.id.setup){
Intent csetup = new Intent(MainActivity.this, Subactivity.class);
startActivity(csetup);
return false;
}
return super.onOptionsItemSelected(item);
}
}
`
Try this:
Add below code in your onCreate method:
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.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
Implement lister in your mainactivity class:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener
And after that in your onNavigationItemSelected method look like this:
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.setup) {
//call new activity
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Hope this may help you
This is because you are overriding the wrong method. You have to override onNavigationItemSelected() for drawer, instead of onOptionsItemSelected() which is for top-right settings menu. See the following code for reference:
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.setup) {
Intent csetup = new Intent(MainActivity.this, Subactivity.class);
startActivity(csetup);
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
First find the view for you NavigationView using findViewById method like below-NavigationView navView=(NavigationView)findViewById(R.id.navView)
then use this.
navView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
int id = item.getItemId();
if (id == R.id.setup) {
Intent csetup = new Intent(MainActivity.this, Subactivity.class);
startActivity(csetup);
}
return false;
}
});
then it will work.. onOptionsItemSelected(MenuItem item) is used to get the access to the MenuItems we have inflated on toolbar or on other layouts using onCreateOptionsMenu() method.

Using Navigation Bar Activity on different Activities with each Activity's content

I am trying to extend other activities into Navigation Bar Activity, I want to use content of the Activity with Navigation Drawer, but when I use setcontentView, Navigation Bar does not work.
This is my Navigation Bar Activity :
:
public class navigationdrawer extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigationdrawer);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.navigationdrawer, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_dashboard) {
Intent i = new Intent(navigationdrawer.this, dashboard.class);
startActivity(i);
// Handle the camera action
} else if (id == R.id.nav_community) {
} else if (id == R.id.nav_recipes) {
Intent i = new Intent(navigationdrawer.this, Recipe.class);
startActivity(i);
} else if (id == R.id.nav_leaderboard) {
} else if (id == R.id.nav_upload) {
} else if (id == R.id.nav_mypics) {
} else if (id == R.id.nav_myvideos) {
} else if (id == R.id.nav_settings) {
} else if (id == R.id.nav_contactus) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
This is my Second Activity :
public class Recipe extends navigationdrawer{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(new View(this));
// Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
// setSupportActionBar(toolbar);
}
}
I have commented setcontentview statement as I know that setcontentview is getting called in the Navigation Drawer Activity but I want Navigation Drawer and the content both. How to achieve this task?
Use fragment instead of activities
Fragment is an part of activity. so, if you want to use singledrawer throughout the app then it is better to use fragment inside your navigationbar activity
note :
use fragment view inside your navigation drawer activity
like
if (id == R.id.nav_dashboard) {
// write code for fragment replacement
}

How to change selected Item in the navigation drawer depending on the activity/view?

I have a Navigation Drawer Activity and different activities in which I get. I want the Items in the nav drawer being selected depending on the activity or view whatever.
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(view.getContext(), MainAddMedActivity.class);
/*EditText editText = (EditText) findViewById(R.id.search_medicament);
String medicament_search = editText.getText().toString();*/
/*intent.putExtra(EXTRA_MESSAGE, medicament_search);*/
startActivity(intent);
}
});
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);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.getMenu().getItem(0).setChecked(true);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
/*navigationView.getMenu().getItem(0).setChecked(true);*/
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_healthdiary) {
} else if (id == R.id.nav_appointment) {
} else if (id == R.id.nav_physician) {
} else if (id == R.id.nav_protocol) {
} 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;
For example, I get into the MainAddMedActivity and Press back. Then I want some code to check in which view or activity I am and select the item in the navigation drawer.
Seems like you have not yet implemented the switching of the content area. I suggest you use fragments for this.
So, if you use fragments, override onAttachFragment of your activity like:
#Override
public void onAttachFragment(Fragment fragment) {
super.onAttachFragment(fragment);
int id;
if(fragment instanceof HealthDiaryFragment) id = R.id.nav_healthdiary;
else
if(fragment instanceof AppointmentFragment) id = R.id.nav_appointment;
...
else return;
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setCheckedItem(id);
}
Also, modify your onBackPressed:
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
if(getFragmentManager().getBackStackEntryCount()>1) {
getFragmentManager().popBackStack();
}
else {
super.onBackPressed();
}
}
/*navigationView.getMenu().getItem(0).setChecked(true);*/
}
This is assuming that in your handling of drawer selection you replace fragments with pushing them on the back stack.

Have all the activities that need that drawer inherit from a custom abstract Activity class, that adds the drawer in its onCreate method.
make a class something like:
public abstract class MyNavigationActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
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);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
}
then:
public class MyActivity extends MyNavigationActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FragmentManager fm = getFragmentManager();
fm.beginTransaction().replace(R.id.content_frame, new MainFragment()).commit();
}
}
