I am new to android app development and in the process of making my first app.
I am trying to create a bottom navigation bar. I have created the actual navigation bar but i am trying to now get it so when i click on that icon it will go to a different page. I currently have it so it will show some text saying you clicked on this button etc. but i am unsure how to make it so it will go to a different page.
This is the code i currently have
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_page);
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_add:
Toast.makeText(MainActivity.this, "Action Add Clicked", Toast.LENGTH_SHORT).show();
break;
case R.id.action_exercise:
Toast.makeText(MainActivity .this, "Action Exercise Clicked", Toast.LENGTH_SHORT).show();
break;
case R.id.action_timer:
Toast.makeText(MainActivity.this, "Action Timer Clicked", Toast.LENGTH_SHORT).show();
break;
}
return true;
}
});
}
}
This is my layout:
<?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"

</RelativeLayout>
This is also the code I'm using within the res/menu
<?xml version="1.0" encoding="utf-8"?>

android:enabled="true"

android:title="Timer"
android:showAsAction="ifRoom"
/>
</menu>

Put this anywhere in your MainActivity
invalidateOptionsMenu();
Override
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
MenuItem item = menu.findItem(R.id.home);
if (item.getTitle().equals("Home")) {
item.setTitle("Your new title"); }
return super.onPrepareOptionsMenu(menu);
}
It would be even better if the text appears below the respective icon while the icons are evenly distributed.
Currently, the items appear stacked in landscape mode.
Current implementation:
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottom_nav_bar"
style="#style/Widget.MaterialComponents.BottomNavigationView.Colored"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:itemIconTint="#color/selector_icon_tint_bottom_nav"
app:itemTextColor="#color/selector_icon_tint_bottom_nav"
app:labelVisibilityMode="labeled"
app:menu="#menu/bottom_nav" />
Try this out I hope it will work.Its working for me
<FrameLayout
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="wrap_content">
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#color/colorPrimary"
app:labelVisibilityMode="labeled"
app:itemIconTint="#color/white"
app:itemTextColor="#color/white"
app:menu="#menu/bottom_navigation_menu" />
</FrameLayout>
Make a menu directory under res and in that directory make an XML layout
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/navigation_home"
android:icon="#drawable/ic_home"
android:title="Home" />
<item
android:id="#+id/navigation_profile"
android:icon="#drawable/ic_profile"
android:title="Profile" />
<item
android:id="#+id/navigation_about"
android:icon="#drawable/ic_aboutUs"
android:title="About Us" />
<item
android:id="#+id/navigation_logout"
android:icon="#drawable/ic_logout"
android:title="Logout" />
</menu>
In main activity implement BottomNavigationView.OnNavigationItemSelectedListener and implements its all method then you can do your desire action on each icon
bottomNavigationView = findViewById(R.id.bottom_navigation_view);
bottomNavigationView.setOnNavigationItemSelectedListener(this);
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_home:
Toast.makeText(this, "Home", Toast.LENGTH_SHORT).show();
return true;
case R.id.navigation_profile:
Toast.makeText(this, "Profile", Toast.LENGTH_SHORT).show();
return true;
case R.id.navigation_about:
Toast.makeText(this, "About Us", Toast.LENGTH_SHORT).show();
return true;
case R.id.navigation_logout:
Toast.makeText(this, "Logout", Toast.LENGTH_SHORT).show();
return true;
}
return false;
}

I'm working on bottom navigation. The problem is that, when I click on one icon on the navigation bar, it is open the activity I want but the icon is appeared it doesn't clicked it just by default the first icon appear as it clicked all the time
public class MainActivity
extends AppCompatActivity
implements
BottomNavigationView.OnNavigationItemSelectedListener {
BottomNavigationView nav;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
nav = (BottomNavigationView) findViewById(R.id.navigation);
nav.setOnNavigationItemSelectedListener(this);
} // ------------------end of on create--------------------
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.prof:
Intent intent = new Intent(MainActivity.this,
profile.class);
menuItem.setIcon(R.drawable.profile);
nav.setItemTextColor(ColorStateList.valueOf(Color.WHITE));
startActivity(intent);
break;
case R.id.hm:
Intent intent1 = new Intent(MainActivity.this,
MainActivity.class);
nav.setItemTextColor(ColorStateList.valueOf(Color.WHITE));
startActivity(intent1);
break;
case R.id.consult:
Intent intent3 = new Intent(MainActivity.this, tabs.class);
nav.setItemTextColor(ColorStateList.valueOf(Color.WHITE));
startActivity(intent3);
break;
case R.id.dash:
Intent intent2 = new Intent(MainActivity.this,

nav.setItemTextColor(ColorStateList.valueOf(Color.WHITE));
startActivity(intent2);
break;
}
return false;

this my interface in all my activity
enter image description here
please help me I update the question
You don't bind any onNavigationItemSelected() listener there; for example:
nav = (BottomNavigationView) findViewById(R.id.navigation);
nav.setNavigationItemSelectedListener(this);
Now I have this
But I want to make this:
<?xml version="1.0" encoding="utf-8"?>
<item
android:id="#+id/menu"
android:icon="#drawable/ic_menu"
android:title="#string/title_menu"
app:showAsAction="always" />
<item
android:id="#+id/file"
android:icon="#drawable/ic_file"
android:title="#string/title_file"
app:showAsAction="always" />
<item
android:id="#+id/new_file"
android:icon="#drawable/ic_new_file"
android:title="#string/title_new_file"
app:showAsAction="always" />
<item
android:id="#+id/visual"
android:icon="#drawable/ic_eye"
android:title="#string/title_eye"
app:showAsAction="always" />
<item
android:id="#+id/print"
android:icon="#drawable/ic_print"
android:title="#string/title_print"
app:showAsAction="always" />
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/title_help" />
This menu I add in activity
override fun onCreateOptionsMenu(menu: Menu): Boolean {
val inflater = menuInflater
inflater.inflate(R.menu.designer_options_menu, menu)
return true
}
And I don't understand how I can install ic_menu at the left side
You can use the Up/Home button for doing that by using a custom toolbar within a CoordinatorLayout:
1. Main layout
<android.support.design.widget.CoordinatorLayout 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"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<!-- My Layout -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
2. Your 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/folder"
android:icon="#drawable/ic_folder_black_24dp"
android:orderInCategory="1"
android:title=""
app:showAsAction="always" />
<item
android:id="#+id/file"
android:icon="#drawable/ic_insert_drive_file_black_24dp"
android:orderInCategory="2"
android:title=""
app:showAsAction="always" />
<item
android:id="#+id/eye"
android:icon="#drawable/ic_remove_red_eye_black_24dp"
android:orderInCategory="3"
android:title=""
app:showAsAction="always" />
<item
android:id="#+id/print"
android:icon="#drawable/ic_print_black_24dp"
android:orderInCategory="4"
android:title=""
app:showAsAction="always" />
</menu>
3. Java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_menu_black_24dp);
getSupportActionBar().setTitle("");
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
Toast.makeText(this, "Home", Toast.LENGTH_SHORT).show();
break;
case R.id.eye:
Toast.makeText(this, "Eye", Toast.LENGTH_SHORT).show();
break;
case R.id.file:
Toast.makeText(this, "File", Toast.LENGTH_SHORT).show();
break;
case R.id.folder:
Toast.makeText(this, "Folder", Toast.LENGTH_SHORT).show();
break;
case R.id.print:
Toast.makeText(this, "Print", Toast.LENGTH_SHORT).show();
break;
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
}
4. Style: use NoActionBar theme
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
</resources>
5. Gradle:: add design support library for coordinator layout
implementation 'com.android.support:design:28.0.0'
The result
Simpler Version
Add android:icon to your Main Activity or whatever Activity you want this icon:
<activity
android:name=".Main"
android:icon="#drawable/ic_settings_white_24dp"
android:launchMode="singleTop">
Enable the "home" icon in your Main.java:
getActionBar().setDisplayShowHomeEnabled( true ); // In your onCreate() or wherever.
You might also want to hide the back icon in the top left and the app name in the top left. You can do that with these two commands:
// Disable back icon in top left and hide app name.
getActionBar().setDisplayHomeAsUpEnabled( false );
getActionBar().setDisplayShowTitleEnabled( false );
To handle the click event you just need to capture the home in onOptionsItemSelected:
#Override
public boolean onOptionsItemSelected( MenuItem item ) {
switch( item.getItemId() ) {
case android.R.id.home:
// Do something.
return true;
}
}
Worked for us and the end result is something like this:
With AppCompatActivity
You need to do this slightly differently if your Activity is extending from AppCompatActivity. Here are the changes to the steps above:
No need to add android:icon to AndroidManifest.xml.
Set the Icon to use in your Main.java Activity and use getSupportActionBar():
getSupportActionBar().setHomeAsUpIndicator( R.drawable.ic_settings_white_24dp );
Android 5.0 Material Design it seems impossible.
You can get that kind of effect using Bottom Navigation Tab.
Try this code hope it helps you
For Bottom Navigation Tab you have to add this line into dependency
compile ‘com.android.support:design:25.0.0’
Here is MainActivity.Java
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);
}
}

Handle click event using this
BottomNavigationView bottomNavigationView = (BottomNavigationView)
findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override

case R.id.action_favorites:
break;
case R.id.action_schedules:
break;
case R.id.action_music:
break;
}
return false;
}
});
Add view in layout
<View
android:layout_width="fill_parent"
android:layout_height="5dip"
android:background="#drawable/drop_shadow" >
</View>
add in your drawable folder drop_shadow.xml
<?xml version="1.0" encoding="utf-8"?>
