I'm working on an Android app for an Engineering Design project that includes a drawer. One of my group members elected to use the android.support.design.widget.NavigationView API to do this, and it's been causing us some problems. Our MainActivity class implements onNavigationItemSelectedListener, which I understand acts as a listener for the items in the drawer and other navigation bars. The problem is, when one of these navigation items is selected, the onNavigationItemSelected method that has been implemented is not called (I know this because it's supposed to put out a message through LogCat if it is called). All the references I've found for this API suggest that I've done everything right so far, but I've apparently missed something, so any help is appreciated.
Here is the relevant code from the MainActivity class:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setUpNavComponents();
setUpMapComponents();
PathfinderDataHandler handler = new PathfinderDataHandler();
}
private void setUpNavComponents()
{
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
navigationView.setNavigationItemSelectedListener(this);
}
private void setUpMapComponents()
{
mapFrag = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
mapFrag.getMapAsync(this);
}
#Override
public boolean onNavigationItemSelected(MenuItem item)
{
// Handle navigation view item clicks here.
int id = item.getItemId();
Log.d(null, "onNavigationItemSelected Called");
if (id == R.id.buildings)
{
// Handle the camera action
Log.d(null, "Buildings selected");
}
else if (id == R.id.blue_phones)
{
Log.d(null, "Blue Phones selected");
}
else if (id == R.id.bus_stops)
{
Log.d(null, "Bus Stops selected");
}
else if (id == R.id.pedways)
{
Log.d(null, "Pedways selected");
}
DrawerLayout drawer = findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Here is the code from activity_main_drawer.xml (Which holds all the items for the drawer)
<?xml version="1.0" encoding="utf-8"?>
<menu 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"
tools:showIn="navigation_view">
<group
android:checkableBehavior="all"
android:enabled="true">
<item
android:id="#+id/buildings"
android:title="#string/building_show_select"
app:actionLayout="#layout/switch_item"
app:showAsAction="always" />
<item
android:id="#+id/blue_phones"
android:title="#string/blue_phone_select"
app:actionLayout="#layout/switch_item"
app:showAsAction="always" />
<item
android:id="#+id/bus_stops"
android:title="#string/bus_stop_select"
app:actionLayout="#layout/switch_item"
app:showAsAction="always" />
<item
android:id="#+id/pedways"
android:title="#string/pedway_select"
app:actionLayout="#layout/switch_item"
app:showAsAction="always" />
</group>
Here is the code for activity_main.xml, which adds the activity_main_drawer to the NavigationView.
<?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:visibility="visible" />
<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.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
Another thing to note is that I'm using Switch items instead of regular Menu items.
And before anyone says anything, YES I know this API is depreciated and I should be using NavigationUI in AndroidX, but I don't have time to refactor the app so I have to make do with this.
You have to provide a non null tag for Log.d(String, String), else there will be nothing written to Logcat.
I tried with
Log.d(null, "HelloWorld");
Log.d("TEST", " HelloWorld");
and got only one line in Logcat:
I am trying to use NavigationView from Android Support Design library in my app. For some reason, OnNavigationItemSelected listener is not being called. Here is my code
Activity Layout
<?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"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/drawer_header"
app:menu="#menu/drawer_menu" />
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.DrawerLayout>
Activity onCreate()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(getLayoutID());
toolbar = (Toolbar) findViewById(R.id.activity_toolbar);
setSupportActionBar(toolbar);
toolbar.inflateMenu(R.menu.common_menu);
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
actionBar.setDisplayHomeAsUpEnabled(true);
}
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(final MenuItem menuItem) {
Snackbar.make(contentLayout, menuItem.getTitle() + " pressed", Snackbar.LENGTH_LONG).show();
menuItem.setChecked(true);
// allow some time after closing the drawer before performing real navigation
// so the user can see what is happening
drawerLayout.closeDrawer(GravityCompat.START);
mDrawerActionHandler.postDelayed(new Runnable() {
#Override
public void run() {
navigate(menuItem.getItemId());
}
}, DRAWER_CLOSE_DELAY_MS);
drawerLayout.closeDrawers();
return true;
}
});
usernameTextView = (TextView) findViewById(R.id.drawer_header_username);
usernameTextView.setText(getAppDContext().getAccount().getUsername());
}
When you make XML layout, you should write down NavigationView after BaseLayout (FrameLayout, LinearLayout, etc..)
<DrawerLayout>
<FrameLayout />
<NavigationView />
</DrawerLayout>
For me this did the trick!
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.bringToFront();
Your activity main layout should look like this:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/navigationDrawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/activity_main_content" />
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
style="#style/NavigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right"
app:headerLayout="#layout/header"
app:menu="#menu/menu_drawer"/>
</android.support.v4.widget.DrawerLayout>
In this NavigationView I linked header.xml and menu_drawer.xml (from menu folder)
for example menu_drawer.xml :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav1"
android:checked="true"
android:icon="#drawable/logo"
android:title="Navigation item 1"/>
<item
android:id="#+id/nav2"
android:icon="#drawable/logo"
android:title="Navigation item 2"/>
</group>
</menu>
than your java code:
public class ActivityMain extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setUpToolbar();
setUpNavDrawer();
}
private void setUpNavDrawer() {
NavigationView view = (NavigationView) findViewById(R.id.navigationView);
mDrawerLayout = (DrawerLayout) findViewById(R.id.navigationDrawer);
view.setNavigationItemSelectedListener(this);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.drawerOpen, R.string.drawerClose);
mDrawerLayout.addDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
}
Check if this work for you. In my project works like a charm.
Saw the new guideline came out, and used in google photos latest app.
Have no idea how to use the new Bottom Navigation Bar.
See through the new support lib, didn't find any lead.
Can not find any official sample.
How to use the new Bottom bar? Don't want to do any customize.
I think you might looking for this.
Here's a quick snippet to get started:
public class MainActivity extends AppCompatActivity {
private BottomBar mBottomBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Notice how you don't use the setContentView method here! Just
// pass your layout to bottom bar, it will be taken care of.
// Everything will be just like you're used to.
mBottomBar = BottomBar.bind(this, R.layout.activity_main,
savedInstanceState);
mBottomBar.setItems(
new BottomBarTab(R.drawable.ic_recents, "Recents"),
new BottomBarTab(R.drawable.ic_favorites, "Favorites"),
new BottomBarTab(R.drawable.ic_nearby, "Nearby"),
new BottomBarTab(R.drawable.ic_friends, "Friends")
);
mBottomBar.setOnItemSelectedListener(new OnTabSelectedListener() {
#Override
public void onItemSelected(final int position) {
// the user selected a new tab
}
});
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mBottomBar.onSaveInstanceState(outState);
}
}

EDIT New Releases.
The Bottom Navigation View has been in the material design guidelines for some time, but it hasn’t been easy for us to implement it into our apps. Some applications have built their own solutions, whilst others have relied on third-party open-source libraries to get the job done. Now the design support library is seeing the addition of this bottom navigation bar, let’s take a dive into how we can use it!
How to use ?
To begin with we need to update our dependency!
compile ‘com.android.support:design:25.0.0’
Design xml.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Content Container -->
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:itemBackground="#color/colorPrimary"
app:itemIconTint="#color/white"
app:itemTextColor="#color/white"
app:menu="#menu/bottom_navigation_main" />
</RelativeLayout>
Create menu as per your requirement.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_favorites"
android:enabled="true"
android:icon="#drawable/ic_favorite_white_24dp"
android:title="#string/text_favorites"
app:showAsAction="ifRoom" />
<item
android:id="#+id/action_schedules"
android:enabled="true"
android:icon="#drawable/ic_access_time_white_24dp"
android:title="#string/text_schedules"
app:showAsAction="ifRoom" />
<item
android:id="#+id/action_music"
android:enabled="true"
android:icon="#drawable/ic_audiotrack_white_24dp"
android:title="#string/text_music"
app:showAsAction="ifRoom" />
</menu>
Handling Enabled / Disabled states. Make selector file.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_checked="true"
android:color="#color/colorPrimary" />
<item
android:state_checked="false"
android:color="#color/grey" />
</selector>
Handle click events.
BottomNavigationView bottomNavigationView = (BottomNavigationView)
findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_favorites:
break;
case R.id.action_schedules:
break;
case R.id.action_music:
break;
}
return false;
}
});
Edit : Using Androidx you just need to add below dependencies.
implementation 'com.google.android.material:material:1.2.0-alpha01'
Layout
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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">
<com.google.android.material.bottomnavigation.BottomNavigationView
android:layout_gravity="bottom"
app:menu="#menu/bottom_navigation_menu"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</FrameLayout>
If you want to read more about it's methods and how it works read this.
Surely it will help you.
You should use BottomNavigationView from v25 Android Support Library.
It represents a standard bottom navigation bar for application.
Here is a post on Medium that has a step by step guide:
https://medium.com/#hitherejoe/exploring-the-android-design-support-library-bottom-navigation-drawer-548de699e8e0#.9vmiekxze
My original answer dealt with the BottomNavigationView, but now there is a BottomAppBar. I added a section at the top for that with an implementation link.
Bottom App Bar
The BottomAppBar supports a Floating Action Button.
Image from here. See the documentation and this tutorial for help setting up the BottomAppBar.
Bottom Navigation View
The following full example shows how to make a Bottom Navigation View similar to the image in the question. See also Bottom Navigation in the documentation.
Add the design support library
Add this line to your app's build.grade file next to the other support library things.
implementation 'com.android.support:design:28.0.0'
Replace the version number with whatever is current.
Create the Activity layout
The only special thing we have added to the layout is the BottomNavigationView. To change the color of the icon and text when it is clicked, you can use a selector instead of specifying the color directly. This is omitted for simplicity here.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:menu="#menu/bottom_nav_menu"
app:itemBackground="#color/colorPrimary"
app:itemIconTint="#android:color/white"
app:itemTextColor="#android:color/white" />
</RelativeLayout>
Notice that we used layout_alignParentBottom to actually put it at the bottom.
Define the menu items
The xml above for Bottom Navigation View referred to bottom_nav_menu. This is what defines each item in our view. We will make it now. All you have to do is add a menu resource just like you would for an Action Bar or Toolbar.
bottom_nav_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_recents"
android:enabled="true"
android:icon="#drawable/ic_action_recents"
android:title="Recents"
app:showAsAction="ifRoom" />
<item
android:id="#+id/action_favorites"
android:enabled="true"
android:icon="#drawable/ic_action_favorites"
android:title="Favorites"
app:showAsAction="ifRoom" />
<item
android:id="#+id/action_nearby"
android:enabled="true"
android:icon="#drawable/ic_action_nearby"
android:title="Nearby"
app:showAsAction="ifRoom" />
</menu>
You will need to add the appropriate icons to your project. This is not very difficult if you go to File > New > Image Asset and choose Action Bar and Tab Icons as the Icon Type.
Add an item selected listener
There is nothing special happening here. We just add a listener to the Bottom Navigation Bar in our Activity's onCreate method.
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationView bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_recents:
Toast.makeText(MainActivity.this, "Recents", Toast.LENGTH_SHORT).show();
break;
case R.id.action_favorites:
Toast.makeText(MainActivity.this, "Favorites", Toast.LENGTH_SHORT).show();
break;
case R.id.action_nearby:
Toast.makeText(MainActivity.this, "Nearby", Toast.LENGTH_SHORT).show();
break;
}
return true;
}
});
}
}
Need more help?
I learned how to do this watching the following YouTube video. The computer voice is a little strange, but the demonstration is very clear.

You can also use Tab Layout with custom tab view to achieve this.

Google has launched the BottomNavigationView after the version 25.0.0 of the design support library. But it came with the following limitations:
You can't remove titles and center icon.
You cant't change titles text size.
Y̶o̶u̶ ̶c̶a̶n̶'̶t̶ ̶c̶h̶a̶n̶g̶e̶ ̶t̶h̶e̶ ̶b̶a̶c̶k̶g̶r̶o̶u̶n̶d̶ ̶c̶o̶l̶o̶r̶ ̶i̶t̶ ̶i̶s̶ ̶a̶l̶w̶a̶y̶s̶ ̶t̶h̶e̶ ̶c̶o̶l̶o̶r̶P̶r̶i̶m̶a̶r̶y̶.̶
It doesn't have a BottomNavigationBehavior: so no integration with FAB or SnackBar through CordinatorLayout.
Every menuItem is a pure extension of FrameLayout so it doesn't have any nice circle reveal effect
So the max you can do with this fist version of BottomNavigationView is: (without any reflection or implementing the lib by yourself).
So, If you want any of these. You can use a third part library like roughike/BottomBar or implement the lib by yourself.
As Sanf0rd mentioned, Google launched the BottomNavigationView as part of the Design Support Library version 25.0.0. The limitations he mentioned are mostly true, except that you CAN change the background color of the view and even the text color and icon tint color. It also has an animation when you add more than 4 items (sadly it cannot be enabled or disabled manually).
I wrote a detailed tutorial about it with examples and an accompanying repository, which you can read here:
https://blog.autsoft.hu/now-you-can-use-the-bottom-navigation-view-in-the-design-support-library/
The gist of it
You have to add these in your app level build.gradle:
compile 'com.android.support:appcompat-v7:25.0.0'
compile 'com.android.support:design:25.0.0'
You can include it in your layout like this:
<android.support.design.widget.BottomNavigationView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/bottom_navigation_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:itemBackground="#color/darkGrey"
app:itemIconTint="#color/bottom_navigation_item_background_colors"
app:itemTextColor="#color/bottom_navigation_item_background_colors"
app:menu="#menu/menu_bottom_navigation" />
You can specify the items via a menu resource like this:
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/action_one"
android:icon="#android:drawable/ic_dialog_map"
android:title="One"/>
<item
android:id="#+id/action_two"
android:icon="#android:drawable/ic_dialog_info"
android:title="Two"/>
<item
android:id="#+id/action_three"
android:icon="#android:drawable/ic_dialog_email"
android:title="Three"/>
<item
android:id="#+id/action_four"
android:icon="#android:drawable/ic_popup_reminder"
android:title="Four"/>
</menu>
And you can set the tint and text color as a color list, so the currently selected item is highlighted:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:color="#color/colorAccent"
android:state_checked="false"/>
<item
android:color="#android:color/white"
android:state_checked="true"/>
</selector>
Finally, you can handle the selection of the items with an OnNavigationItemSelectedListener:
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment fragment = null;
switch (item.getItemId()) {
case R.id.action_one:
// Switch to page one
break;
case R.id.action_two:
// Switch to page two
break;
case R.id.action_three:
// Switch to page three
break;
}
return true;
}
});
Other alternate library you can try :- https://github.com/Ashok-Varma/BottomNavigation
<com.ashokvarma.bottomnavigation.BottomNavigationBar
android:layout_gravity="bottom"
android:id="#+id/bottom_navigation_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
BottomNavigationBar bottomNavigationBar = (BottomNavigationBar) findViewById(R.id.bottom_navigation_bar);
bottomNavigationBar
.addItem(new BottomNavigationItem(R.drawable.ic_home_white_24dp, "Home"))
.addItem(new BottomNavigationItem(R.drawable.ic_book_white_24dp, "Books"))
.addItem(new BottomNavigationItem(R.drawable.ic_music_note_white_24dp, "Music"))
.addItem(new BottomNavigationItem(R.drawable.ic_tv_white_24dp, "Movies & TV"))
.addItem(new BottomNavigationItem(R.drawable.ic_videogame_asset_white_24dp, "Games"))
.initialise();
i've made a private class which uses a gridview and a menu resource:
private class BottomBar {
private GridView mGridView;
private Menu mMenu;
private BottomBarAdapter mBottomBarAdapter;
private View.OnClickListener mOnClickListener;
public BottomBar (#IdRes int gridviewId, #MenuRes int menuRes,View.OnClickListener onClickListener) {
this.mGridView = (GridView) findViewById(gridviewId);

https://github.com/pocheshire/BottomNavigationBar
It's https://github.com/roughike/BottomBar ported to C# for Xamarin developers
There is a new official BottomNavigationView in version 25 of the Design Support Library
https://developer.android.com/reference/android/support/design/widget/BottomNavigationView.html
add in gradle
compile 'com.android.support:design:25.0.0'
XML
<android.support.design.widget.BottomNavigationView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:design="http://schema.android.com/apk/res/android.support.design"

This library, BottomNavigationViewEx, extends Google's BottomNavigationView. You can easily customise Google's library to have bottom navigation bar the way you want it to be. You can disable the shifting mode, change visibility of the icons and texts and so much more. Definitely try it out.
I have referred this github post and I have set the three layouts for three fragment pages in bottom tab bar.
FourButtonsActivity.java:
bottomBar.setFragmentItems(getSupportFragmentManager(), R.id.fragmentContainer,
new BottomBarFragment(LibraryFragment.newInstance(R.layout.library_fragment_layout), R.drawable.ic_update_white_24dp, "Recents"),
new BottomBarFragment(PhotoEffectFragment.newInstance(R.layout.photo_effect_fragment), R.drawable.ic_local_dining_white_24dp, "Food"),
new BottomBarFragment(VideoFragment.newInstance(R.layout.video_layout), R.drawable.ic_favorite_white_24dp, "Favorites")
);
To set the badge count :
BottomBarBadge unreadMessages = bottomBar.makeBadgeForTabAt(1, "#E91E63", 4);
unreadMessages.show();
unreadMessages.setCount(4);
unreadMessages.setAnimationDuration(200);
unreadMessages.setAutoShowAfterUnSelection(true);
LibraryFragment.java:
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class LibraryFragment extends Fragment {
private static final String STARTING_TEXT = "Four Buttons Bottom Navigation";
public LibraryFragment() {
}
public static LibraryFragment newInstance(int resource) {
Bundle args = new Bundle();
args.putInt(STARTING_TEXT, resource);
LibraryFragment sampleFragment = new LibraryFragment();
sampleFragment.setArguments(args);
return sampleFragment;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = LayoutInflater.from(getActivity()).inflate(
getArguments().getInt(STARTING_TEXT), null);
return view;
}
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="?android:attr/windowBackground"
app:menu="#menu/navigation" />
navigation.xml(inside menu)
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/navigation_home"
android:icon="#drawable/ic_home_black_24dp"
android:title="#string/title_home"
app:showAsAction="always|withText"
android:enabled="true"/>
Inside onCreate() method,
BottomNavigationView navigation = (BottomNavigationView)findViewById(R.id.navigation);
//Dont forgot this line
BottomNavigationViewHelper.disableShiftMode(navigation);
And Create class as below.
public class BottomNavigationViewHelper {
public static void disableShiftMode(BottomNavigationView view) {
BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
try {
Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
shiftingMode.setAccessible(true);
shiftingMode.setBoolean(menuView, false);
shiftingMode.setAccessible(false);
for (int i = 0; i < menuView.getChildCount(); i++) {
BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
//noinspection RestrictedApi
item.setShiftingMode(false);
// set once again checked value, so view will be updated
//noinspection RestrictedApi
item.setChecked(item.getItemData().isChecked());
}
} catch (NoSuchFieldException e) {
Log.e("BNVHelper", "Unable to get shift mode field", e);
} catch (IllegalAccessException e) {
Log.e("BNVHelper", "Unable to change value of shift mode", e);
}
}
}
You can create the layouts according to the above-mentioned answers
If anyone wants to use this in kotlin:-
private val mOnNavigationItemSelectedListener = BottomNavigationView.OnNavigationItemSelectedListener { item ->
when (item.itemId) {
R.id.images -> {
// do your work....
return#OnNavigationItemSelectedListener true
}
R.id.videos ->
{
// do your work....
return#OnNavigationItemSelectedListener true
}
}
false
}
then in oncreate you can set the above listener to your view
mDataBinding?.navigation?.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener)
I'm changing locale programmatically from fragment and everything ok. There is one exception, the NavigationView menu, where language didn't changing. How to refresh it without recreate all activity.
Mainactivity code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = this;
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.setEnabled(false);
DrawerLayout mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
}
R.layout.activity_main
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<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>
fragment code after choose locale
LocaleHelper.setLocale(getActivity(), getResources().getStringArray(R.array.locale)[locale]);
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.detach(this).attach(this).commit();
<group android:checkableBehavior="single">
<item android:id="#+id/nav_contacts" android:icon="#drawable/ic_people_black_24dp"
android:title="#string/contacts" android:checked="true"/>
<item android:id="#+id/nav_invoices" android:icon="#drawable/ic_swap_horiz_black_24dp"
android:title="#string/invoices" />
<item android:id="#+id/nav_payments" android:icon="#drawable/ic_payment_black_24dp"
android:title="#string/payments" />
<item android:id="#+id/nav_history" android:icon="#drawable/ic_receipt_black_24dp"
android:title="#string/history" />
<item android:id="#+id/nav_settings" android:icon="#drawable/ic_settings_black_24dp"
android:title="#string/settings" />
<item android:id="#+id/nav_info"
android:title="#string/info" android:icon="#android:drawable/ic_dialog_info"/>
</group>
Thanx
I've decided this problem
private void refreshNavigationView(){
getActivity().setContentView(R.layout.activity_main);
NavigationView navigationView = (NavigationView) getActivity().findViewById(R.id.nav_view);
}
That's enought for refresh NavigationView after change locale
But I lose onNavigationItemSelected
As a result at Mainactivity
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the locale has changed
if (!currentLocale.equals(newConfig.locale)) {
currentLocale = newConfig.locale;
this.setContentView(R.layout.activity_main);
NavigationView navigationView = (NavigationView) this.findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(MainActivity.this);
}
}
At fragment
getActivity().onConfigurationChanged(getActivity().getResources().getConfiguration());
You can try below code. I haven't tested it but I hope it will work.
for (int i = 0, count = navigationView.getChildCount(); i < count; i++) {
final View child = navigationView.getChildAt(i);
if (child != null && child instanceof ListView) {
final ListView menuView = (ListView) child;
final HeaderViewListAdapter adapter = (HeaderViewListAdapter) menuView.getAdapter();
final BaseAdapter wrapped = (BaseAdapter) adapter.getWrappedAdapter();
wrapped.notifyDataSetChanged();
}
}
latest solution in kotlin:
upgrade your appcompat version to 1.6.0 or later
implementation 'androidx.appcompat:appcompat:1.6.0'
create a function
fun setLocale(language: String?) {
val appLocale: LocaleListCompat = LocaleListCompat.forLanguageTags(language)
AppCompatDelegate.setApplicationLocales(appLocale)
}
then use it like
setLocale("en-EN")
it will update and refresh all language change/locale including NavigationView
I'm planning to implement a navigation bar to let users navigate to different activites.
But here's the problem,
I've found plenty articles about creating a navigation drawer but it seems doesn't work for me , because my UI doesn't have any titlebar.
And what i actually want is to call up the navigation drawer whenever users press on a button near to the navigation drawer.
Is there any possible way to do this ?
It is very simple.
Here is your main activity's layout, activity_main.xml:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:layout_height="match_parent">
<FrameLayout
android:animateLayoutChanges="true"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
tools:ignore="MergeRootFrame" />
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/drawer_list_header"
app:menu="#menu/navigation"/>
</android.support.v4.widget.DrawerLayout>
And here's your MainActivity:
public class MainActivity extends AppCompatActivity {
NavigationView navigationView;
DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.navi_1:
// on 1st item in the menu, do something
break;
case R.id.navi_2:
// on 2nd item in the menu, do something
break;
}
drawerLayout.closeDrawers();
return false;
}
});
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
}
// [...]
private void openDrawer() {
if (!drawerLayout.isDrawerOpen(navigationView)) {
drawerLayout.openDrawer(navigationView);
}
}
private void closeDrawer() {
if (drawerLayout.isDrawerOpen(navigationView)) {
drawerLayout.closeDrawers();
}
}
}
Now you can open the drawer with openDrawer() and close it with closeDrawer().
A sample navigation.xml file which is located under the menu dir in the res (resources) folder:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="#+id/navi_1"
android:checked="true"
android:icon="#drawable/ic_android"
android:title="First item"/>
<item
android:id="#+id/navi_2"
android:icon="#drawable/ic_android"
android:title="Second item"/>
</group>
</menu>
Sample drawer_list_header.xml file, located under the layout dir in the res folder:
<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:paddingBottom="8dp"
android:src="#drawable/list_header_final">
</ImageView>
Here are some notes:
You have to declare a menu file for the drawer, see app:menu="#menu/navigation" in the layout file.
You might want to declare a header layout, which is displayed over the menu elements in the drawer, see app:headerLayout="#layout/drawer_list_header".
The drawer can be opened by a fling-like action from the edge of the screen. To prevent the users from doing that, you might want to lock/unlock your drawer on action using drawerLayout.setDrawerLockMode(...);, see the documentation for details.
Also note that in order to use NavigationView, you'll need the latest design support lib by adding the dependency to your module's gradle file: compile 'com.android.support:design:22.2.0'.
See more about it here.
Yes you can implement DrawerLayout with out ActionBar. You can manually open and close the DrawerLayout like
drawerLayout.openDrawer(Gravity.LEFT);
drawerLayout.closeDrawer(Gravity.LEFT);
