I have added BottomNavigationView
in my application like.
main.xml
<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" />
bottom_navigation_main.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_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>
MainActivity click
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_favorites:
//need change icon of favotites here.
case R.id.action_schedules:
case R.id.action_music:
}
return true;
}
});
I want to change the icon of the bottom navigation of selected position. How can we achieve this feature when user click one item?
(if user clicked one item then the icon change to another one)

By default android sets primary color as selected item color in navigation bars. If you set the desired selection color (e.g. blue) as
<item name="colorPrimary">@color/blue</item>
the selection color will be blue without doing anything else.

I found this is better approach to use selector drawable:
At first create an xml file in your drawable folder. For example, xml file name is child_selector.xml at drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/child" android:state_checked="false"/>
<item android:drawable="@drawable/child_fill" android:state_checked="true"/>
</selector>
Simply add child_selector in menu item of your bottom_navigation_main.xml:
Like: android:icon="@drawable/child_selector"
Example:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/navigation_child"
android:icon="@drawable/child_selector"
android:title="@string/title_child" />
</menu>
And must add following line in your activity-
bottomNavigationView.setItemIconTintList(null);

On Material 3
You need to create a style and put your colors on:
<style name="BottomNavigationView">
<item name="colorSecondaryContainer">@color/background_dark</item>
<item name="colorSurface">?attr/colorPrimaryVariant</item>
<!-- Icon color Active -->
<item name="colorOnSecondaryContainer">@color/yellow</item>
<!-- Text Color Active -->
<item name="colorOnSurface">@color/yellow</item>
</style>
To see inactive colors, check the documentation.

You can dynamically set your icon using this method.
R.id.navigation_menu
is your item id in your R.menu.menu_bottom_navigation
.
val menuItem = bottomNavigationView.menu.findItem(R.id.navigation_menu)
menuItem.setIcon(R.drawable.ic_icon)

The above answer from ajay singh https://stackoverflow.com/a/57248961/9793057 helped me out, as well as employing answers from above.
The following code within res->drawable folder (selector_stock_bottom_nav_view.xml)
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/button_and_tab_color" android:state_checked="true" />
<item android:color="@android:color/darker_gray" android:state_checked="false" />
</selector>
These are the attributes in my bottom navigation view
<com.google.android.material.bottomnavigation.BottomNavigationView
app:itemIconTint="@drawable/selector_stock_bottom_nav_view" //To change icon color
app:itemTextColor="@drawable/selector_stock_bottom_nav_view" //To change text color
app:itemTextAppearanceActive="@style/stockBottomNavigationView.Active" //To change size of text during active state
app:itemTextAppearanceInactive="@style/stockBottomNavigationView.InActive"
app:menu="@menu/bottom_navigation_menu"
app:labelVisibilityMode="labeled"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
app:selectedBackgroundVisible="false"
android:id="@+id/stock_bottom_navigation"/>
I DID-NOT use "BottomNavigationView.setItemIconTintList(null)" anywhere in my code.
Now here comes the most important piece of code, make sure to return "TRUE" in bottom navigation view's listener, i.e,
private BottomNavigationView.OnNavigationItemSelectedListener stockBottomNavListener = new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
return true;
}
};
Bonus: To change size of text active/inactive state Place the following code in styles.xml file
<style name="stockBottomNavigationView.InActive" parent="@style/TextAppearance.AppCompat.Caption">
<item name="android:textSize">7sp</item>
</style>
<style name="stockBottomNavigationView.Active" parent="@style/TextAppearance.AppCompat.Caption">
<item name="android:textSize">8sp</item>
</style>
The above answer is a compilation of answers from various answers in stackoverflow related to bottom navigation views, icon & text color/size change.

In the Latest material Design library default behavior of BottomNavigation is provided where you don't need to provide property itemIconTint
it will manage it automatically.
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="@+id/bottomNavigationView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="0dp"
android:layout_marginEnd="0dp"
android:layout_alignParentBottom="true"
android:background="?android:attr/windowBackground"
app:itemBackground="@color/white"
app:itemTextColor="@color/textBlue"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="@menu/bottom_navigation"
app:labelVisibilityMode="labeled"
app:itemTextAppearanceActive="@color/colorPrimary"
/>

Thanks for the selector
method, that works for me (api v26
)
For those who wondering how to set it back to origin unselected icon programmatically, consider add this to your OnNavigationItemSelectedListener
before your switch(Java)
or when(Kotlin)
:
private val mOnNavigationItemSelectedListener = BottomNavigationView.OnNavigationItemSelectedListener { item ->
navigation.menu.getItem(0).setIcon(R.drawable.ic_tab_home)
navigation.menu.getItem(1).setIcon(R.drawable.ic_tab_account)
navigation.menu.getItem(2).setIcon(R.drawable.ic_tab_trading)
navigation.menu.getItem(3).setIcon(R.drawable.ic_tab_wallet)
when (item.itemId) {
R.id.navigation_home -> {
message.setText(R.string.title_home)
item.setIcon(R.drawable.ic_tab_home_active)
return@OnNavigationItemSelectedListener true
}
R.id.navigation_account -> {
message.setText(R.string.title_account)
item.setIcon(R.drawable.ic_tab_account_active)
return@OnNavigationItemSelectedListener true
}
R.id.navigation_trading -> {
message.setText(R.string.title_trading)
item.setIcon(R.drawable.ic_tab_trading_active)
return@OnNavigationItemSelectedListener true
}
R.id.navigation_wallet-> {
message.setText(R.string.title_wallet)
item.setIcon(R.drawable.ic_tab_wallet_active)
return@OnNavigationItemSelectedListener true
}
}
false
}

Okay I wanted to understand how to have each item have their own image, and with some confusion in the comments on where it should go, I wanted to type up this answer.
First create your menu and its items. Your selector will go inside those items in the ICON value. Here we have 2 selectors, each made for its menu item.
item
android:id="@+id/navigation_home"
android:icon="@drawable/navigation_home_selector"
android:title="@string/title_home" />
item
android:id="@+id/navigation_profile"
android:icon="@drawable/navigation_profile_selector"
android:title="@string/title_profile" />
Now here is your selector file that will be housed in your drawable folder.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/menu_selected" android:state_checked="true"/>
<item android:drawable="@drawable/menu" android:state_checked="false"/>
</selector>
Final step was provided by @ KishanSolanki124
Add this line of code to your BottomNavigationView.
BottomNavigationView.setItemIconTintList(null);
There you have it. All works like a charm.

If above solutions are not working for you to change selected item icon then add below line to your code:
bottomNavigationView.setItemIconTintList(null);
This will disable tint effect of selected item icon.
I had the same problem. I have added selector drawable for changing icon of BottomNavigationView item when its checked/selected.

You can simply create drawable selector in drawable folder and image can be change according to the state of the widget used in view
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/calender_green" android:state_checked="true"/>
<item android:drawable="@drawable/calender_black" android:state_checked="false"/>
</selector>

You need to reset the icon onclick, and then on the switch case you need to set only the one you need to change, so only when selected the icon change.
Menu menu = bottomNavigationView.getMenu();
menu.findItem(R.id.action_favorites).setIcon(favDrawable);
switch (item.getItemId()) {
case R.id.action_favorites:
item.setIcon(favDrawableSelected);
case R.id.action_schedules:
case R.id.action_music:
}
