I am creating an app in which I created a bottom navigation bar. Now what I want is to set separate colors for selected/unselected state of nav bar items. So I created an xml file and set it for item tint and text color for navigation bar as shown:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="#android:color/holo_blue_dark" />
<item android:color="#android:color/darker_gray" />
</selector>
and in main menu adding navigation bar as:
<android.support.design.widget.BottomNavigationView
android:id="#+id/mainNav"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:background="#android:color/white"
android:elevation="8dp"
app:itemIconTint="#color/nav_bar_item_state"
app:itemTextColor="#color/nav_bar_item_state"
app:menu="#menu/nav_items"></android.support.design.widget.BottomNavigationView>
I got this solution from this link:
Selected tab's color in Bottom Navigation View
But when I run the app it crashes with error "unable to inflate navigation bar". What am I doing wrong? Any help would be appreciated.
Update:
I tried the same thing by creating selector file in drawable file but unfortunately it also doesn't work.
Try this:-
Set item.setCheckable(true) inside onNavigationItemSelected()
public boolean onNavigationItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_home:
item.setCheckable(true);
mTextMessage.setText(R.string.title_home);
return true;
}
return false;
}
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)
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>
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);
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 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:
}
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>

Add this line of code to your BottomNavigationView.
BottomNavigationView.setItemIconTintList(null);
There you have it. All works like a charm.
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.
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
}
Found the answer. we can use
item.setIcon(R.drawable.icon_name)
to change the icon .. will try to imporve answer
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_favorites:
//change the icon
item.setIcon(R.drawable.icon_name);
case R.id.action_schedules:
case R.id.action_music:
}
return true;
}
});
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)
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.
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"
/>
I have exactly the same problem as in these threads:
No actions or icons showing on the actionbar; only in overflow
Menu items won't show up in the actiobar
No one has offered a solution, so I want to bring it up again.
I have a xml-file, my_menu.xml, that look like this:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/delete"
android:showAsAction="ifRoom|withText"
android:icon="#drawable/ic_delete_image"
android:title="delete"/>
</menu>
My activity extends ActionBarActivity and implements these methods:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.delete:
//delete something
break;
}
return(true);
}
In my book: "A value of ifRoom means that the menu item will appear in the action bar if there is space for it" - I have tested to use ifRoom, ifRoom|withText and always, but the item always ends up in the overflow menu. I have tested the application on different devices, and it's plenty of room. Do anyone have a solution to this?

My activity extends ActionBarActivity
As is covered in the documentation, if you are using the appcompat_v7 backport of the action bar, and its associated ActionBarActivity, your menu resource needs to have showAsAction in a namespace custom to your app:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
<item
android:id="#+id/delete"
yourapp:showAsAction="ifRoom|withText"
android:icon="#drawable/ic_delete_image"
android:title="delete"/>
</menu>
Here is a complete sample project demonstrating the use of the appcompat_v7 action bar.
Try changing it to
<item
android:id="#+id/delete"
android:showAsAction="always|withText"
android:icon="#drawable/ic_delete_image"
android:title="delete"/>
Hope this will help you.
I want to provide a image button in place of action bar and on clicking that I want to display list of options and again on clicking any particular option I want to pass Intent.
How can I achieve this?Does anybody know
If so help me out.
Thank you...
In order to display the imagebutton in Actionbar. First add an item in main.xml.Which is Under MENU Folder.
for ex:
main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/stopwatch"
android:orderInCategory="50"
android:icon="#drawable/ic_action_alarms"
android:showAsAction="always|withText"
android:title="Stopwatch"/>
</menu>
then add the following code in your mainActivity.java
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch(item.getItemId())
{
case (R.id.stopwatch):
Toast.makeText(getApplicationContext(), "Stopwatch", Toast.LENGTH_SHORT).show();
Intent i=new Intent(getApplicationContext(), Stopwatch.class);
startActivity(i);
break;
return super.onOptionsItemSelected(item);
}
and Don't forget to create another java class as Stopwatch.java
Go through the following link it will help you
https://developer.android.com/training/basics/actionbar/adding-buttons.html
You can set a custom view on your action bar, here is the link
How to display custom view in ActionBar?
It can be done in two ways
Options 1: Create an layout XML with your image button, and set that layout to action bar.
For example: In you activity copy the following lines.
ActionBar actionBar = getSupportActionBar();
LayoutInflater inflator = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.search, null);
actionBar.setCustomView(v);
Now display a PopUp menu when the user clicks a ImageButton.
Option 2:
Instead of setting the view for the ActionBar , you can use sub-Menu's in the action bar. For this you need to create sub-Menu.
for example:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/file"
android:icon="#drawable/ic_new_game"
android:title="#string/file" >
<!-- "file" submenu -->
<menu>
<item android:id="#+id/create_new"
android:title="#string/create_new" />
<item android:id="#+id/open"
android:title="#string/open" />
</menu>
</item>
</menu>
Set an icon for the main `MenuItem` so it looks like an `ImageButton`, when the user click the first MenuItem it displays the its sub-`Menu`
I'm using a normal Action Bar Sherlock Action Bar but noticed that, if I opted to hold down on the item as opposed to clicking on it, a black box would appear. I have two questions:
What is its intended purpose?
How do I get rid of it?
XML Code:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/refresh_button_actionbar"
android:icon="#drawable/refresh_circle"
android:showAsAction="always">
</item>
</menu>
onOptionsItemSelected:
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.refresh_button_actionbar:
this.refresh();
break;
default:
return false;
}
return true;
}
The black box is somekind of toast indicating the "description" of your button.
<item
android:id="#+id/refresh_button_actionbar"
android:icon="#drawable/refresh_circle"
android:title="Refresh"
android:showAsAction="always">
Add the android:title tag into your menu item and you will see it appear on black box, not sure how to get rid of it tough.
