As I liked the design from BottomNavigationView I decided to implement a new Menu for my App with it, instead of just using simple buttons.
I took this post as a guideline.
According to BottomNavigationView's documentation, its purpose is to
provide quick navigation between top-level views of an app. It is
primarily designed for use on mobile.
In my case, I just want each MenuItem to launch an activity, but by default there is always one MenuItem selected:
I tried to set the color to white with:
app:itemIconTint="#color/white"
app:itemTextColor="#color/white"
Still, visibly selected MenuItem is different from others (Title size bigger), which is still bothering me:
I came with the idea to place a hidden MenuItem to select like:
<item
android:id="#+id/uncheckedItem"
android:title="" />
and make its view GONE:
bottomNavigationView.getMenu().findItem(R.id.uncheckedItem).setChecked(true);
bottomNavigationView.findViewById(R.id.uncheckedItem).setVisibility(View.GONE);
This makes all MenuItems unchecked, but by default BottomNavigationView is hidding Titles, as it has more than 3 MenuItems to display, even if the fourth MenuItem is settle to GONE:
So my question remains, is there away/hack to unselect all MenuItems and keep its titles being displayed?
mNavigationBottom.getMenu().setGroupCheckable(0, false, true);
To unselect all items I have create this extension:
fun BottomNavigationView.uncheckAllItems() {
menu.setGroupCheckable(0, true, false)
for (i in 0 until menu.size()) {
menu.getItem(i).isChecked = false
}
menu.setGroupCheckable(0, true, true)
}
menu.setGroupCheckable(0, true, false) make it possible.
The third parameter made the menu not exclusive and then within the loop you change the checked status.
To finish set the menu to exclusive again.
Here the doc
Thanks for your idea. I have implement it in my lib.
I have a better way do it by reflect. So it won't show space.
If you have interest. Click here : https://github.com/ittianyu/BottomNavigationViewEx
private void initBottomViewAndLoadFragments(final BottomNavigationViewEx bnve) {
bnve.enableAnimation(false);
bnve.enableShiftingMode(false);
bnve.enableItemShiftingMode(false);
// use the unchecked color for first item
bnve.setIconTintList(0, getResources().getColorStateList(R.color.bnv_unchecked_black));
bnve.setTextTintList(0, getResources().getColorStateList(R.color.bnv_unchecked_black));
bnve.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
private boolean firstClick = true;
private int lastItemId = -1;
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
// restore the color when click
if (firstClick) {
firstClick = false;
bnve.setIconTintList(0, getResources().getColorStateList(R.color.selector_bnv));
bnve.setTextTintList(0, getResources().getColorStateList(R.color.selector_bnv));
}
if (firstClick || lastItemId == -1 || lastItemId != item.getItemId()) {
lastItemId = item.getItemId();
} else {
return false;
}
// do stuff
return fillContent(item.getItemId());
}
});
}
-- res/color/selector_bnv.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/bnv_checked_white" android:state_checked="true" />
<item android:color="#color/bnv_unchecked_black" />
</selector>
-- res/values/colors.xml
<color name="bnv_checked_white">#android:color/white</color>
<color name="bnv_unchecked_black">#android:color/black</color>
Your solution seems change the space between items
There is my solution :
"Just set color of clicked same as color of un-clicked."
for example:
private void changeMenuItemCheckedStateColor(BottomNavigationView bottomNavigationView, String checkedColorHex, String uncheckedColorHex) {
int checkedColor = Color.parseColor(checkedColorHex);
int uncheckedColor = Color.parseColor(uncheckedColorHex);
int[][] states = new int[][] {
new int[] {-android.R.attr.state_checked}, // unchecked
new int[] {android.R.attr.state_checked}, // checked
};
int[] colors = new int[] {
uncheckedColor,
checkedColor
};
ColorStateList colorStateList = new ColorStateList(states, colors);
bottomNavigationView.setItemTextColor(colorStateList);
bottomNavigationView.setItemIconTintList(colorStateList);
}
if you want to un-check all items, you can
changeMenuItemCheckedStateColor(mBottomNavigationView, "#999999", "#999999");
if you want to restore the color setting, you can
changeMenuItemCheckedStateColor(mBottomNavigationView, "FF743A", "999999");
I found my own solution merging my progress with this post.
Steps:
Update proguard-rules.pro and sync build
Create Helper to disable BottomNavigationView Shift Mode
Create an Item to hide on Menu.xml
Inflate BottomNavigationView
Set Item to be hidden as Checked GONE
Use Helper to disable Shifting Mode
Output:
Working code:
proguard-rules.pro:
-keepclassmembers class android.support.design.internal.BottomNavigationMenuView {
boolean mShiftingMode;
}
BottomNavigationShiftHelper.java:
public class BottomNavigationShiftHelper {
private final static String TAG = "DEBUG_BOTTOM_NAV_UTIL";
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);
item.setShiftingMode(false);
// set once again checked value, so view will be updated
item.setChecked(item.getItemData().isChecked());
}
} catch (NoSuchFieldException e) {
Log.d(TAG, "Unable to get shift mode field");
} catch (IllegalAccessException e) {
Log.d(TAG, "Unable to change value of shift mode");
}
}
}
Activity Sample.java:
private void loadNavigationBar() {
BottomNavigationView bottomNavigationView = (BottomNavigationView)
findViewById(R.id.navigation_bar);
bottomNavigationView.getMenu().findItem(R.id.uncheckedItem).setChecked(true);
bottomNavigationView.findViewById(R.id.uncheckedItem).setVisibility(View.GONE);
BottomNavigationViewUtils.disableShiftMode(bottomNavigationView);
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.newList:
//Do The Math
break;
case R.id.loadList:
//Do The Math
break;
case R.id.settings:
//Do The Math
break;
}
return false;
}
});
}
BottomNavigationMenu.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/newList"
android:enabled="true"
android:icon="#drawable/new_list"
android:title="#string/common.button.list.new"
app:showAsAction="withText" />
<item
android:id="#+id/loadList"
android:enabled="true"
android:icon="#drawable/load"
android:title="#string/common.button.list.load"
app:showAsAction="withText" />
<item
android:id="#+id/settings"
android:enabled="true"
android:icon="#drawable/settings"
android:title="#string/common.label.settings"
app:showAsAction="withText" />
<item
android:id="#+id/uncheckedItem"
android:title="" />
</menu>
BottomNavigationComponent (inside Activity.xml):
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation_bar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
app:itemIconTint="#color/white"
app:itemTextColor="#color/white"
android:background="#drawable/BottomNavigationMenu.xml"
app:menu="#menu/supercart_bottom_navigation" />
Try this, it worked for me
<item
android:id="#+id/uncheckedItem"
android:visible="false"
android:title="" />
and set
bottomNavigationView.getMenu().findItem(R.id.uncheckedItem).setChecked(true);
you get all menu item view as unselected; since the selection is given for uncheckedItem which is invisible
Hope it helped you.
There is an exception in accepted answer which we set maximum item we cant implement that code.So I got a code that is more simple than accepted code and it's also working with maximum item.
I referred from here Custom TextSize of BottomNavigationView support android
In your dimen.xml you can put:
<dimen name="design_bottom_navigation_text_size" tools:override="true">10sp</dimen>
<dimen name="design_bottom_navigation_active_text_size" tools:override="true">10sp</dimen>
Doing this you are overriding the default value of dimen that the internal classes of BottomNavigationView use. So be carreful.
Set this code in your onCreate method where the bottom navigation view initialized
mNavigationBottom.getMenu().setGroupCheckable(0, false, true);
and Last set your bottom navigation bar like this :
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/nav_view"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
android:background="?android:attr/windowBackground"
android:fitsSystemWindows="true"
app:labelVisibilityMode="labeled"
app:layout_anchorGravity="fill"
app:menu="#menu/bottom_nav_menu" />
In this set your app:labelVisibilityMode to labeled
This is the same as the accepted answer except I have changed two lines of code marked below. When looping through the BottomNavigationItemViews, I set checked to false always and I also set checkable to false. This prevents the Menu Items from changing size. You still need this proguard rule:
-keepclassmembers class android.support.design.internal.BottomNavigationMenuView {
boolean mShiftingMode;
}
Updated code:
static void removeShiftMode(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);
item.setShiftingMode(false);
item.setChecked(false); // <--- This line changed
item.setCheckable(false); // <-- This line was added
}
}
catch (NoSuchFieldException e)
{
Log.e("ERROR NO SUCH FIELD", "Unable to get shift mode field");
}
catch (IllegalAccessException e)
{
Log.e("ERROR ILLEGAL ALG", "Unable to change value of shift mode");
}
}
The best answer mNavigationBottom.getMenu().setGroupCheckable(0, false, true) did not work for me. It still showed the first item as being selected.
What did work for me is to have an invisible item and to select that, exactly like you did in the question.
Add app:labelVisibilityMode="labeled" to your BottomNavigationView so that all items remain in view with their titles.
if(isDarkMode(context)) {
mBotNavView.setItemIconTintList(ColorStateList.valueOf(Color.parseColor("#FFFFFF")));
} else {
mBotNavView.setItemIconTintList(ColorStateList.valueOf(Color.parseColor("#000000")));
}
public boolean isDarkMode(Context context) {
int nightModeFlags = context.getResources().getConfiguration().uiMode & Configuration.UI_MODE_NIGHT_MASK;
return darkMode = (nightModeFlags == Configuration.UI_MODE_NIGHT_YES);
}
I have a problem with searchview implementation in android toolbar.
The empty space padding is too big.
I don't want to hide other actions, but these actions are
overlapped by SearchView.
SearchView's underline is not visible
How do i fix issues mentioned above ?
menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"

fragment
#Override
public void onCreateOptionsMenu(final Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_fragment_reg_vehicles, menu);
final MenuItem item = menu.findItem(R.id.action_search);
searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setQueryHint("Search");
searchView.setMaxWidth(Integer.MAX_VALUE);
searchView.setIconifiedByDefault(false);
searchView.setOnQueryTextListener(this);
searchView.setOnCloseListener(new SearchView.OnCloseListener() {
#Override
public boolean onClose() {
setItemsVisibility(menu, item, true);
return false;
}
});
searchView.setOnSearchClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
setItemsVisibility(menu, item, false);
searchView.requestFocus();
}
});
}
Regarding your posted code, this is the output:
As you can see, there is two left margins: the widget's container and the magnify icon. This is why you have an empty space bigger than an another window with a title. And the menu items are pushed outside the toolbar which, I think, it's the default SearchView ActionView when it's not a CollapseActionView so it fills the parent.
From the source of SearchView widget and its layout abc_search_view.xml, I tried to remove the extra margins and avoid pushing the other items outside the toolbar.
But after many manipulations, my guess is you have to use a custom widget and/or a custom layout. Or to play with setIconifiedByDefault(true) which removes the magnify icon and its extra margin and to use setMaxWidth(MAX_SIZE) where MAX_SIZE is calculated dynamically by Integer.MAX_VALUE - (SIZE_OF_A_MENU_ITEM * NB_OF_MENU_ITEMS)... But it requires a lot of work for nothing. So using a custom layout could be the solution.
However, there is a possible way to keep the appcompat widget, some little workarounds. First, to avoid puhsing out the other items, you can use the CollapseActionView.
<item
...
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always|collapseActionView"/>
And to maintain your requirements, you have to expand it when you initialize it:
final SearchView searchView =
(SearchView) MenuItemCompat.getActionView(item);
MenuItemCompat.expandActionView(item);
Be aware that you have to use setOnActionExpandListener() in order to close the window if you don't want to collapse the item. This suggestion will give you this result:
Still the extra margins, right? Therefore, you have to retrieve the container and the magnify icon by their ids (which you can find in abc_search_view.xml... but let's save some time: they are R.id.search_edit_frame and R.id.search_mag_icon). You can remove their margins by using this method:
private void changeSearchViewElements(View view) {
if (view == null)
return;
if (view.getId() == R.id.search_edit_frame
|| view.getId() == R.id.search_mag_icon) {
LinearLayout.LayoutParams p =
(LinearLayout.LayoutParams) view.getLayoutParams();
p.leftMargin = 0; // set no left margin
view.setLayoutParams(p);
}
if (view instanceof ViewGroup) {
ViewGroup viewGroup = (ViewGroup) view;
for (int i = 0; i < viewGroup.getChildCount(); i++) {
changeSearchViewElements(viewGroup.getChildAt(i));
}
}
}
By calling it in a thread:
final SearchView searchView =
(SearchView) MenuItemCompat.getActionView(item);
...
searchView.post(new Runnable() {
#Override
public void run() {
changeSearchViewElements(searchView);
}
});
Here's the output:
Finally, to get the line under the field, there is a possible workaround as using a 9-patch drawable and set it as a background. You can easily find how-to on Google. So the condition will be:
private void changeSearchViewElements(View view) {
...
if (view.getId() == R.id.search_edit_frame
|| view.getId() == R.id.search_mag_icon) {
LinearLayout.LayoutParams p =
(LinearLayout.LayoutParams) view.getLayoutParams();
p.leftMargin = 0; // set no left margin
view.setLayoutParams(p);
} else if (view.getId() == R.id.search_src_text) {
AutoCompleteTextView searchEdit = (AutoCompleteTextView) view;
searchEdit.setBackgroundResource(R.drawable.rect_underline_white);
}
...
}
From the OP's comment below, the underline's field can also be done with the following statement:
searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text)
.setBackgroundResource(R.drawable.abc_textfield_search_default_mtrl_alpha);
After these workarounds, as I said, it might be easier to use a custom layout. But if you want to keep the default SearchView widget, this might help.
So I have a menu item, that's defined as:
<item
android:id="#+id/action_live"
android:title="#string/action_live"
android:orderInCategory="1"
app:showAsAction="ifRoom|withText" />
It shows as text, as you can see below:
And I want to programmatically change the "LIVE" text color. I've searched for a while and I found a method:
With globally defined:
private Menu mOptionsMenu;
and:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
mOptionsMenu = menu;
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
I do:
MenuItem liveitem = mOptionsMenu.findItem(R.id.action_live);
SpannableString s = new SpannableString(liveitem.getTitle().toString());
s.setSpan(new ForegroundColorSpan(Color.RED), 0, s.length(), 0);
liveitem.setTitle(s);
But nothing happens!
If I do the same for an item of the overflow menu, it works:
Is there some limitation for app:showAsAction="ifRoom|withText" items? Is there any workaround?
Thanks in advance.
Bit late to the party with this one, but I spent a while working on this and found a solution, which may be of use to anyone else trying to do the same thing. Some credit goes to Harish Sridharan for steering me in the right direction.
You can use findViewById(R.id.MY_MENU_ITEM_ID) to locate the menu item (provided that the menu had been created and prepared), and cast it to a TextView instance as suggested by Harish, which can then be styled as required.
public class MyAwesomeActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
super.onCreate(savedInstanceState);
// Force invalidatation of the menu to cause onPrepareOptionMenu to be called
invalidateOptionsMenu();
}
private void styleMenuButton() {
// Find the menu item you want to style
View view = findViewById(R.id.YOUR_MENU_ITEM_ID_HERE);
// Cast to a TextView instance if the menu item was found
if (view != null && view instanceof TextView) {
((TextView) view).setTextColor( Color.BLUE ); // Make text colour blue
((TextView) view).setTextSize(TypedValue.COMPLEX_UNIT_SP, 24); // Increase font size
}
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean result = super.onPrepareOptionsMenu(menu);
styleMenuButton();
return result;
}
}
The trick here is to force the menu to be invalidated in the activity's onCreate event (thereby causing the onPrepareMenuOptions to be called sooner than it would normally). Inside this method, we can locate the menu item and style as required.
#RRP give me a clue ,but his solution does not work for me. And #Box give a another, but his answer looks a little not so cleaner. Thanks them. So according to them, I have a total solution.
private static void setMenuTextColor(final Context context, final Toolbar toolbar, final int menuResId, final int colorRes) {
toolbar.post(new Runnable() {
#Override
public void run() {
View settingsMenuItem = toolbar.findViewById(menuResId);
if (settingsMenuItem instanceof TextView) {
if (DEBUG) {
Log.i(TAG, "setMenuTextColor textview");
}
TextView tv = (TextView) settingsMenuItem;
tv.setTextColor(ContextCompat.getColor(context, colorRes));
} else { // you can ignore this branch, because usually there is not the situation
Menu menu = toolbar.getMenu();
MenuItem item = menu.findItem(menuResId);
SpannableString s = new SpannableString(item.getTitle());
s.setSpan(new ForegroundColorSpan(ContextCompat.getColor(context, colorRes)), 0, s.length(), 0);
item.setTitle(s);
}
}
});
}
In order to change the colour of menu item you can find that item, extract the title from it, put it in a Spannable String and set the foreground colour to it. Try out this code piece
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
MenuItem mColorFullMenuBtn = menu.findItem(R.id.action_submit); // extract the menu item here
String title = mColorFullMenuBtn.getTitle().toString();
if (title != null) {
SpannableString s = new SpannableString(title);
s.setSpan(new ForegroundColorSpan(Color.parseColor("#FFFFFF")), 0, s.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE); // provide whatever color you want here.
mColorFullMenuBtn.setTitle(s);
}
return super.onCreateOptionsMenu(menu);
}
It only becomes a text view after inspection, its real class is ActionMenuItemView, on which we can further set the text color like this:
public static void setToolbarMenuItemTextColor(final Toolbar toolbar,
final #ColorRes int color,
#IdRes final int resId) {
if (toolbar != null) {
for (int i = 0; i < toolbar.getChildCount(); i++) {
final View view = toolbar.getChildAt(i);
if (view instanceof ActionMenuView) {
final ActionMenuView actionMenuView = (ActionMenuView) view;
// view children are accessible only after layout-ing
actionMenuView.post(new Runnable() {
#Override
public void run() {
for (int j = 0; j < actionMenuView.getChildCount(); j++) {
final View innerView = actionMenuView.getChildAt(j);
if (innerView instanceof ActionMenuItemView) {
final ActionMenuItemView itemView = (ActionMenuItemView) innerView;
if (resId == itemView.getId()) {
itemView.setTextColor(ContextCompat.getColor(toolbar.getContext(), color));
}
}
}
}
});
}
}
}
}
You could put the change of the color in the onPrepareOptionsMenu:
override fun onPrepareOptionsMenu(menu: Menu?): Boolean
{
val signInMenuItem = menu?.findItem(R.id.menu_main_sign_in)
val title = signInMenuItem?.title.toString()
val spannable = SpannableString(title)
spannable.setSpan(
ForegroundColorSpan(Color.GREEN),
0,
spannable.length,
Spannable.SPAN_INCLUSIVE_INCLUSIVE)
SgnInMenuItem?.title = spannable
return super.onPrepareOptionsMenu(menu)
}
of course you can make it shorter above...
now you can change the color appearance upon other (ie. viewmodel) values...

I spent a lot of hours on this and finally got it into work. There is easy solusion for Android 6 and 7 but it doesn't work on Android 5. This code works on all of them. So, if you are doing it in Kotlin this is my suggestion:
override fun onCreateOptionsMenu(menu: Menu): Boolean {
menuInflater.inflate(R.menu.my_menu, menu)
setToolbarActionTextColor(menu, R.color.black)
this.menu = menu
return true
}
private fun setToolbarActionTextColor(menu: Menu, color: Int) {
val tb = findViewById<Toolbar>(R.id.toolbar)
tb?.let { toolbar ->
toolbar.post {
val view = findViewById<View>(R.id.my_tag)
if (view is TextView) {
view.setTextColor(ContextCompat.getColor(this, color))
} else {
val mi = menu.findItem(R.id.my_tag)
mi?.let {
val newTitle: Spannable = SpannableString(it.title.toString())
val newColor = ContextCompat.getColor(this, color)
newTitle.setSpan(ForegroundColorSpan(newColor),
0, newTitle.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
it.title = newTitle
}
}
}
}
}
It's complicated, but you can use the app:actionLayout attribute. For example,
my_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/englishList"
android:orderInCategory="1"
app:showAsAction="ifRoom|withText"
app:actionLayout="#layout/custom_menu_item_english_list"
android:title=""/>
</menu>
custom_menu_item_english_list.xml:
<?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"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical">
<androidx.appcompat.widget.AppCompatTextView
android:id="#+id/englishListWhiteText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:lineHeight="16dp"
android:textSize="16sp"
android:text="英文"
android:layout_marginRight="8dp"/>
</LinearLayout>
MainActivity.java:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my_menu, menu);
MenuItem item = menu.findItem(R.id.englishList);
item.getActionView().findViewById(R.id.englishListWhiteText)
.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v){
//Handle button click.
}
});
return true;
}

if you are using popup menu function to show the menu items in the application and trying to change the design or color of your text items in the menu list, first create a style item in your style.xml file:
<style name="PopupMenuStyle" parent="Widget.AppCompat.PopupMenu">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_gravity">center</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:textColor">#color/ColorPrimary</item>
<item name="android:textSize">#dimen/textsize</item>
<item name="android:fontFamily">#font/myfonts</item></style>
and use this style in your code as:
val popupWrapper = ContextThemeWrapper(this, R.style.PopupMenuStyle)
val popup = PopupMenu(popupWrapper, your_menu_view)
MenuItem as defined by documentation is an interface. It will definitely be implemented with a view widget before being portrayed as an menu. Most cases these menu items are implemented as TextView. You can use UiAutomatorViewer to see the view hierarchy or even use hierarchyviewer which will be found in [sdk-home]/tools/. Attached one sample uiautomatorviewer screenshot for a MenuItem
So you can always typecast your MenuItem and set the color.
TextView liveitem = (TextView)mOptionsMenu.findItem(R.id.action_live);
liveitem.setTextColor(Color.RED);
EDIT:
Since there was request to see how to use this tool, I'm adding a few more contents.
Make sure you have set environment variable $ANDROID_HOME pointing to your SDK HOME.
In your terminal:
cd $ANDROID_HOME
./tools/uiautomatorviewer
This tool will open up.
The second or third button (refer screenshot) in the menu will capture the screenshot of your attached device or emulator and you can inspect the view and their hierarchy. Clicking on the view will describe the view and their information. It is tool purposely designed for testing and you can inspect any application.
Refer developer site for more info: uiautomatorviewer
i have action bar in my application that displays menu items defined in my res/menu/activity_main.xml
My menu items are aligned to right on action bar. I want them to be aligned to left.
Only solutions i found for this used custom action bar, like this one:
Positioning menu items to the left of the ActionBar in Honeycomb
However, i dont want to create custom layout for my menu. I want to use default menu items generated from my res/menu/activity_main.xml.
Is this possible?
Well, i was curious about this, so i dug deep inside the SDK's source. I used AppCompatActivity with 3 menu item in it's XML file, and i used the default onCreateOptionMenu method, which was this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
After i move on from the inflate method with the debugger, i went through the following stack:

It ended in BaseMenuPresenter's updateMenuView method, this is where the revelant work is done.
the method's code:
public void updateMenuView(boolean cleared) {
final ViewGroup parent = (ViewGroup) mMenuView;
if (parent == null) return;
int childIndex = 0;
if (mMenu != null) {
mMenu.flagActionItems();
ArrayList<MenuItemImpl> visibleItems = mMenu.getVisibleItems();
final int itemCount = visibleItems.size();
for (int i = 0; i < itemCount; i++) {
MenuItemImpl item = visibleItems.get(i);
if (shouldIncludeItem(childIndex, item)) {
final View convertView = parent.getChildAt(childIndex);
final MenuItemImpl oldItem = convertView instanceof MenuView.ItemView ?
((MenuView.ItemView) convertView).getItemData() : null;
final View itemView = getItemView(item, convertView, parent);
if (item != oldItem) {
// Don't let old states linger with new data.
itemView.setPressed(false);
ViewCompat.jumpDrawablesToCurrentState(itemView);
}
if (itemView != convertView) {
addItemView(itemView, childIndex);
}
childIndex++;
}
}
}
// Remove leftover views.
while (childIndex < parent.getChildCount()) {
if (!filterLeftoverView(parent, childIndex)) {
childIndex++;
}
}
}
Here the getItemView and the addItemView methods do what their's name say. The first inflate a new view, and the second add it to parent. What is more important, under the debugger the parent object can be checked, it's an ActionMenuView, which inherits from the LinearLayout and inflated form abc_action_menu_layout.xml.
This means if you can get this view, you can do what you want. Theoretically, i think it can be done with lots of reflection, but it would painful.
Instead of that, you can reproduce it in your code. Implementations can be found here.
According to the things above, the answer for your question is YES, it can be done, but it will be tricky.
Edit:
I created a proof of concept for doing this with reflection. I've used com.android.support:appcompat-v7:23.1.0.
I've tried this on an emulator(Android 6.0) and on my Zuk Z1(CM Android 5.1.1), on both it works fine.

}
Although the gravity has been changed here, on the screen this does not make any revelant difference. To get a real visible change other layout params(e.g. width ) should be tuned.
All in all, a custom layout is much easier to use.
You can do it like this:
activity.getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM,
ActionBar.DISPLAY_SHOW_CUSTOM);
activity.getActionBar().setCustomView(mAutoSyncSwitch, new ActionBar.LayoutParams(
ActionBar.LayoutParams.WRAP_CONTENT,
ActionBar.LayoutParams.WRAP_CONTENT,
Gravity.CENTER_VERTICAL | Gravity.LEFT));
I'm having a bit of trouble customizing the search icon in the SearchView. On my point of view, the icon can be changed in the Item attributes, right? Just check the code bellow..
Can someone tell me what I'm doing wrong?
This is the menu I'm using, with my custom search icon icn_lupa. But when I run the app, I always get the default search icon...
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu_search"
android:title="#string/menu_search"
android:icon="#drawable/icn_lupa"
android:showAsAction="always"
android:actionViewClass="android.widget.SearchView" />
</menu>
I've found another way to change the search icon which goes in the same line as Diego Pino's answer but straight in onPrepareOptionsMenu.
In your menu.xml (same as before)
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/action_search"
android:icon="#drawable/ic_action_fav"
android:title="#string/action_websearch"
android:showAsAction="always|never"
android:actionViewClass="android.widget.SearchView" />
</menu>
In your activity:
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
MenuItem searchViewMenuItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) searchViewMenuItem.getActionView();
int searchImgId = getResources().getIdentifier("android:id/search_button", null, null);
ImageView v = (ImageView) mSearchView.findViewById(searchImgId);
v.setImageResource(R.drawable.your_new_icon);
mSearchView.setOnQueryTextListener(this);
return super.onPrepareOptionsMenu(menu);
}
I followed the example for changing the edittext in this example.
You should be able to do this for all icons/backgrounds in your SearchView, to find the right ID you can check here.
UPDATE November 2017:
Since this answer android has been updated with the possibility of changing the search icon through the XML.
If you target anything below android v21 you can use:
<android.support.v7.widget.SearchView
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:searchIcon="#drawable/ic_search_white_24dp"
app:closeIcon="#drawable/ic_clear_white_24dp" />
Or v21 and later:
<SearchView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:searchIcon="#drawable/ic_search_white_24dp"
android:closeIcon="#drawable/ic_clear_white_24dp" />
And there are even more options:
closeIcon
commitIcon
goIcon
searchHintIcon
searchIcon
voiceIcon
Nice answer from #just_user
For my case, since I am using the appcompat v7 library for the SearchView + ActionBar, i modified his solution a bit to make it compatible to my project, it should work so as long as you did not modify anything when you added appcompat v7 as library
XML:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:metrodeal="http://schemas.android.com/apk/res-auto" >
<item
android:id="#+id/main_menu_action_search"
android:orderInCategory="100"
android:title="#string/search"
metrodeal:showAsAction="always"
metrodeal:actionViewClass="android.support.v7.widget.SearchView"
android:icon="#drawable/search_btn"/>
</menu>
Java code:
#Override
public void onPrepareOptionsMenu(Menu menu) {
MenuItem searchViewMenuItem = menu.findItem(R.id.main_menu_action_search);
SearchView mSearchView = (SearchView) MenuItemCompat.getActionView(searchViewMenuItem);
int searchImgId = android.support.v7.appcompat.R.id.search_button; // I used the explicit layout ID of searchview's ImageView
ImageView v = (ImageView) mSearchView.findViewById(searchImgId);
v.setImageResource(R.drawable.search_btn);
super.onPrepareOptionsMenu(menu);
}
Excuse for the very big icon (I have not resized the icon just yet), but it should work as it is.
I was struggling with this too but then I accidentaly used 'collapseActionView' and that fixed it!
My menu.xml looks like this now:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu_search"
android:title="#string/menu_search"
android:showAsAction="always|withText|collapseActionView"
android:actionViewClass="android.widget.SearchView"
android:icon="#android:drawable/ic_menu_search" />
</menu>
The downside of this is that on tablets the SearchView will appear on the left side of the ActionBar instead of where the searchicon is, but I don't mind that.
I defined a style to do it .
here is my xml:
<android.support.v7.widget.SearchView
android:id="#+id/sv_search"
android:icon="#android:drawable/ic_menu_search"
android:layout_width="fill_parent"
**style="#style/CitySearchView"**
android:layout_height="wrap_content"/>
and this is my style:
<style name="CitySearchView" parent="Base.Widget.AppCompat.SearchView">
<item name="searchIcon">#drawable/ic_more_search</item>
</style>
That it！
After finish that，just take a look at Base.Widget.AppCompat.SearchView.
<style name="Base.Widget.AppCompat.SearchView" parent="android:Widget">
<item name="layout">#layout/abc_search_view</item>
<item name="queryBackground">#drawable/abc_textfield_search_material</item>
<item name="submitBackground">#drawable/abc_textfield_search_material</item>
<item name="closeIcon">#drawable/abc_ic_clear_mtrl_alpha</item>
<item name="searchIcon">#drawable/abc_ic_search_api_mtrl_alpha</item>
<item name="goIcon">#drawable/abc_ic_go_search_api_mtrl_alpha</item>
<item name="voiceIcon">#drawable/abc_ic_voice_search_api_mtrl_alpha</item>
<item name="commitIcon">#drawable/abc_ic_commit_search_api_mtrl_alpha</item>
<item name="suggestionRowLayout">#layout/abc_search_dropdown_item_icons_2line</item>
</style>
every item can be override by define a new style .
Hope it helps!
There's a way to do this. The trick is to recover the ImageView using its identifier and setting a new image with setImageResource(). This solution is inspired on Changing the background drawable of the searchview widget.
private SearchView searchbox;
private void customizeSearchbox() {
setSearchHintIcon(R.drawable.new_search_icon);
}
private void setSearchHintIcon(int resourceId) {
ImageView searchHintIcon = (ImageView) findViewById(searchbox,
"android:id/search_mag_icon");
searchHintIcon.setImageResource(resourceId);
}
private View findViewById(View v, String id) {
return v.findViewById(v.getContext().getResources().
getIdentifier(id, null, null));
}
SearchView searchView = (SearchView) findViewById(R.id.address_search);
try {
Field searchField = SearchView.class
.getDeclaredField("mSearchButton");
searchField.setAccessible(true);
ImageView searchBtn = (ImageView) searchField.get(searchView);
searchBtn.setImageResource(R.drawable.search_glass);
} catch (NoSuchFieldException e) {
} catch (IllegalAccessException e) {
}
After some research I found the solution here. The trick is that the icon is not in an ImageView but in the Spannable object.
// Accessing the SearchAutoComplete
int queryTextViewId = getResources().getIdentifier("android:id/search_src_text", null, null);
View autoComplete = searchView.findViewById(queryTextViewId);
Class<?> clazz = Class.forName("android.widget.SearchView$SearchAutoComplete");
SpannableStringBuilder stopHint = new SpannableStringBuilder(" ");
stopHint.append(getString(R.string.your_new_text));
// Add the icon as an spannable
Drawable searchIcon = getResources().getDrawable(R.drawable.ic_action_search);
Method textSizeMethod = clazz.getMethod("getTextSize");
Float rawTextSize = (Float)textSizeMethod.invoke(autoComplete);
int textSize = (int) (rawTextSize * 1.25);
searchIcon.setBounds(0, 0, textSize, textSize);
stopHint.setSpan(new ImageSpan(searchIcon), 1, 2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
// Set the new hint text
Method setHintMethod = clazz.getMethod("setHint", CharSequence.class);
setHintMethod.invoke(autoComplete, stopHint);
In menu xml:
<item
android:id="#+id/menu_filter"
android:actionLayout="#layout/menu_filter"
android:icon="#drawable/ic_menu_filter"
android:orderInCategory="10"
android:showAsAction="always"
android:title="#string/menu_filter"/>
and create the layout/menu_filter:
<?xml version="1.0" encoding="utf-8"?>
<SearchView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:searchIcon="#drawable/ic_menu_filter"/>
then in activity's onCreateOptionsMenu or onPrepareOptionsMenu:
SearchView searchView = (SearchView) menu.findItem(R.id.menu_filter).getActionView();
searchView.setOnQueryTextListener(this);
It looks like the actionViewClass overides the icon and it doesn't look like you can change it from this class.
You got two solutions:
Live with it and I think it's the best option in terms of user experience and platform conformity.
Define your own actionViewClass
<SearchView
android:searchIcon="#drawable/ic_action_search"
..../>
use the searchIcon xml tag
This works with Material Design (MaterialComponents theme) and BottomAppBar.
If you are using androidx library, for example:
<item
android:id="#+id/sv"
android:title="#string/search"
app:actionViewClass="androidx.appcompat.widget.SearchView"
app:showAsAction="always" />
You can create a method and invoke it from wherever you want:
/**
* Set SearchView Icon
* #param i Drawable icon
*/
private void setSVIcon(int i) {
ImageView iv = searchView.findViewById(androidx.appcompat.R.id.search_button);
iv.setImageDrawable(ResourcesCompat.getDrawable(getResources(), i, null));
}
Usage example:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(m, menu);
MenuItem mn = menu.findItem(R.id.sv);
if (mn != null) {
searchview = (SearchView) mn.getActionView();
setSVIcon(R.drawable.ic_sr);
}
}
Update hint of AutocompleteTextView for updating search icon in the expanded mode, copied from android source,
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
mSearchMenuItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) mSearchMenuItem.getActionView();
int searchImgId = getResources().getIdentifier("android:id/search_button", null, null);
ImageView v = (ImageView) searchView.findViewById(searchImgId);
v.setImageResource(R.drawable.search_or);
int searchTextViewId = searchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
AutoCompleteTextView searchTextView = (AutoCompleteTextView) searchView.findViewById(searchTextViewId);
searchTextView.setHintTextColor(getResources().getColor(R.color.hint_color_white));
searchTextView.setTextColor(getResources().getColor(android.R.color.white));
searchTextView.setTextSize(18.0f);
SpannableStringBuilder ssb = new SpannableStringBuilder(" "); // for the icon
ssb.append(hintText);
Drawable searchIcon = getResources().getDrawable(R.drawable.search_or);
int textSize = (int) (searchTextView.getTextSize() * 1.25);
searchIcon.setBounds(0, 0, textSize, textSize);
ssb.setSpan(new ImageSpan(searchIcon), 1, 2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
searchTextView.setHint(ssb);
return super.onPrepareOptionsMenu(menu);
}
From API 21 you can change it in xml:
android:searchIcon="#drawable/loupe"
android:closeIcon="#drawable/x_white"
for api level < 21, i did this:
int searchImgId = getResources().getIdentifier("android:id/search_mag_icon", null, null);
ImageView ivIcon = (ImageView) searchView.findViewById(searchImgId);
if(ivIcon!=null)
ivIcon.setImageResource(R.drawable.ic_search);
from this
to this
There are three magnifying glass icons. two of them are shown when IconizedByDefault is true(one which is shown before pressing and one is shown in the "hint") and one is shown all the time when IconizedByDefault is false. all the fields are private so the way to get them is by their xml id. (most of the code is mentioned separately in other answers in this post already)
when IconizedByDefault is true change the icon in the hint (which is seen only after pressing the icon) by :
mSearchSrcTextView = (SearchAutoComplete)findViewById(R.id.search_src_text);
then do the same as in the android source code:
final int textSize = (int) (mSearchSrcTextView.getTextSize() * 1.25);
newSearchIconDrawable.setBounds(0, 0, textSize, textSize);
final SpannableStringBuilder ssb = new SpannableStringBuilder(" ");
ssb.setSpan(new ImageSpan(newSearchIconDrawable), 1, 2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
ssb.append(hintText);
mSearchHintIcon was replaced with newSearchIconDrawable which is your new search icon.
Then set the hint with
mSearchSrcTextView.setHint(ssb);
The other 2 icons are in an ImageView, which can be found by their Id.
for the icon when searchview is closed (when iconizedByDefault is true) do:
mSearchButton = (ImageView) findViewById(R.id.search_button);
and for the one that always appears (if iconizedByDefault is false)
mCollapsedIcon = (ImageView) findViewById(R.id.search_mag_icon);
Desperate solution using Kotlin
val s = (searchView.getAllChildren().firstOrNull() as? LinearLayout)?.getAllChildren()?.filter { it is AppCompatImageView }?.firstOrNull() as? AppCompatImageView
s?.setImageResource(R.drawable.search)
getAllChildren:
fun ViewGroup.getAllChildren() : ArrayList<View> {
val views = ArrayList<View>()
for (i in 0..(childCount-1)) {
views.add(getChildAt(i))
}
return views
}
Hope it helps someone.
My solution:
Use two menu xml files. In one of the xmls the menu item has an actionView and in the other one no. Initially inflate the collapsed menu and when the menu item is clicked, invalidate the menu and inflate the expanded menu xml and make sure you call setIconified(false);
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
if(!mShowSearchView)
{
inflater.inflate(R.menu.menu_collapsed, menu);
}
else
{
inflater.inflate(R.menu.menu_expanded, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
searchView.setIconified(false);
searchView.setOnCloseListener(new OnCloseListener()
{
#Override
public boolean onClose()
{
mShowSearchView = false;
ActivityCompat.invalidateOptionsMenu(getActivity());
return false;
}
});
}
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (item.getItemId() == R.id.action_filter)
{
menu.showMenu();
}
else if (item.getItemId() == R.id.action_search)
{
mShowSearchView = true;
ActivityCompat.invalidateOptionsMenu(getActivity());
}
return super.onOptionsItemSelected(item);
}
Just name your icon the same name as the icon that is used by the search view. When it compiles it takes the resource in the project over the icon in the library.
I use the AppCompat library. Yes, specifying android:icon="#drawable/search_icon_png" doesnt work.
So i looked into the source code of #style/Theme.AppCompat and found the icon that android uses.
<item name="searchViewSearchIcon">#drawable/abc_ic_search</item>
So if you rename your search icon inside your drawables to abc_ic_search.png, this icon is rendered as its found in your app drawable first, rather than the appcompat drawable folder.
Works for me :)
Using this approach you can customize the close and clear icons for the search widget as well.
