I am developing an android app through support design library for navigation drawer and toolbar.I am switching to fragment on click of navigation drawer item such as rootfragment->fragment1 ->fragment2 ->fragment3. So far there is no problem.but when i want to come back on rootFragment such as rootfragment<-fragment1 <- fragment2 <- fragment3.On this toolbar is going invisible on each fragment. How to solve that problem.

Main Activity code is:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
private TextView userName,userEmailId;
private ImageView profileImage;
#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);
navigationView.getMenu().getItem(0).setChecked(true);
Fragment fragment = new HomeFragment();
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();

fragmentTransaction.commit();
}
#Override
public void onBackPressed()
{
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
finish();
}
}
#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

return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item)
{
// Handle navigation view item clicks here.
//int id = item.getItemId();
Fragment fragment;
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
switch(item.getItemId()) {
case R.id.home:
fragment = new HomeFragment();
fragmentTransaction.replace(R.id.containerView, fragment, null);
fragmentTransaction.commit();
break;
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
Toolbar is inside of "containerView". Then you replace the "containerView" with the content of the fragments => the toolbar is not visible. To fix the problem move the Toobar outside of the "containerView".
Another approach is to have the "containerView" below the toolbar, like in the code below:
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:minHeight="?android:attr/actionBarSize"
android:background="?attr/colorPrimary"
android:id="#+id/toolbar"
android:theme="#style/ThemeOverlay.AppCompat.Dark"/>
<FrameLayout
android:id="#+id/containerView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
Please replace MainActivity XML with this:
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

In my app, I am using a custom action bar. Then I tried to add a Home Button to open the Navigation Drawer. But when I tried to click the button, nothing happened. The Home Button isn't responding to clicks.
Here's my code:
activity_main.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

MainActivity.java:
public class MainActivity extends AppCompatActivity {
DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.main_toolbar);
setSupportActionBar(toolbar);
ActionBar bar = getSupportActionBar();
bar.setDisplayHomeAsUpEnabled(true);
bar.setHomeAsUpIndicator(R.drawable.ic_menu);
bar.setHomeButtonEnabled(true);
drawerLayout = findViewById(R.id.main_drawer_layout);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
drawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
How can I fix this?
I want when a button from the navigation menu is clicked to start a new activity. With the current code nothing happens when the button is clicked. I'm new to Android so plese don't get mad if I don't understand your code and ask some questions.
Here is my navigation_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/nav_account"
android:title="Home"
android:icon="#mipmap/ic_home_black_24dp">
</item>
<item android:id="#+id/nav_delete"
android:title="Delete Boards"
android:icon="#mipmap/ic_close_black_24dp">
</item>
<item android:id="#+id/nav_settings"
android:title="Settings"
android:icon="#mipmap/ic_settings_black_24dp">
</item>
And here is my mainActivity.java code for the drawer:
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mToggle.onOptionsItemSelected(item)){
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.nav_delete) {
//call new activity
}
}
return super.onOptionsItemSelected(item);
}
}
MainActivity.xml code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout

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 XML file is like this:
<?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"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
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.nav_delete) {
//call new activity
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Hope this may help you
Did you inflate the navigation menu?
If not, make sure your navigation menu is in the res/menu folder and then add:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.navigation_menu, menu);
return true;
}
try this :
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item)
{
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_account)
{
//your intent
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
In main activity implement listner for navigation menu.
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener
and in activity find navigation view reference and set the listner.
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
Full code :
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);

My Activity code:
#Override

super.onCreate(savedInstanceState);
Overview overview = new Overview();
Intent intent = getIntent();
user.setUserName(intent.getStringExtra("Username"));
setContentView(R.layout.activity_second);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.mycontainer, overview)
.commit();
}
Toolbar toolbar = (Toolbar) findViewById(R.id.my_toolbar);
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
toggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.addDrawerListener(toggle);
toggle.syncState();
NavigationView navView = (NavigationView) findViewById(R.id.navview);
navView.setNavigationItemSelectedListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {

return true;
}
// Toggle function for the navigational drawer
#Override
public boolean onOptionsItemSelected(MenuItem item){
if(toggle.onOptionsItemSelected(item)){
return true;
}
return super.onOptionsItemSelected(item);
}
After adding this line:
getSupportActionBar().setDisplayShowTitleEnabled(false);
My drawer dissapeared. So all I have left is my actionbar_menu.

So basically, how do I get both my actionbar, my DrawerLayout and a custom title to work? I have to disable the showTitleEnabled to set a custom title, but it makes my menu dissapear. So how do I fix this?
You can create a custom toolbar layout and include it in your XML instead of <android.support.v7.widget.Toolbar>
and in your custom toolbar layout put a TextView.
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Was missing. This fixes it
I am using android default navigation drawer and i want that same layout for all the activities i tried searching on internet i got some ideas for customized drawer but not on android studio default drawer. Kindly help me.

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton)
findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override

Here in app_bar_main layout i would like to change that
include layout="#layout/content_main" with my activity or fragment so that i can have the same layout.
Thanks in advance.
Create an Activity containing only NavigationDrawer and after that OnItemSelected from NavigationDrawer call every activity you want. Then NavigationDrawer will be available in all the activities.
The other solution is create MainActivity with NavigationDrawer and create other Fragments instead of Activities. Call those Fragmnets OnItemSelected from NavigationDrawer. There are alot of example available there.
Edit
In your activity where you have defined navigationDrawer, do the following. And instead of creating new activities for next layouts, create fragments and call them on OnItemSelected on navigationDrawer like below:
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()) {
//Replacing the main content with ContentFragment Which is our Inbox View;
case R.id.drawer_home:
Intent intent=new Intent(HomeActivity.this, HomeActivity.class);
startActivity(intent);
overridePendingTransition(0, 0);
finish();
return true;
// For rest of the options we just show a toast on click
case R.id.drawer_artist:
android.support.v4.app.FragmentManager fragmentManager=getSupportFragmentManager();
android.support.v4.app.FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.content_frame, new ArtistsFragment());
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
return true;
default:
Toast.makeText(getApplicationContext(), "Somethings Wrong", Toast.LENGTH_SHORT).show();
return true;
}
}
});
Fragment code will be like:
public class ArtistsFragment extends Fragment {
public ArtistsFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootview= inflater.inflate(R.layout.fragment_artists, container, false);
return rootview;
}}

I'm trying to develop an app with multiple activities and the same navigation drawer and toolbar.
I've created a BaseActivity for initialization of drawer and other activities extend it, but I have problems with toolbar, in particular when using setSupportActionBar(toolbar).
How can I fix this problem?
BaseActivity.java
public abstract class BaseActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
private DrawerLayout drawer;
private ActionBarDrawerToggle toggle;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(getLayoutResourceId());
}
protected abstract int getLayoutResourceId();
public void initDrawer() {
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toggle = new ActionBarDrawerToggle(
(Activity) this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.setDrawerIndicatorEnabled(true);
toggle.syncState();
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.food) {
final Intent intent = new Intent(this, FoodDiary.class);
startActivity(intent);
}
drawer.closeDrawer(GravityCompat.START);

You can't use same Navigation Drawer and Toolbar with different Activities.
If you want different screens with the same components, you have to use Fragments with one Activity, for example FragmentActivity.
