Android ToolBar menu items selected state color (Over flow menu items selected color )

I want to change selected state text color of overflow menu items as shown.
OverFlow menu
I have tried with styling activity as <item name="actionMenuTextColor">#color/text_color</item> but this changes the entire color of menu text whether it is selected or not . Is there any way to do this by custom styling ? or i have to do this programmatically ?
I am using Xamarin.Android

You could create a menu :
Create a menu folder place in Resource folder, then create a file.For example, menu_main.xml file :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/add_item"
android:title="Add" />
<item
android:id="#+id/remove_item"
android:title="Remove" />
</menu>
Then in your Activity add the menu in OnCreateOptionsMenu method :
public override bool OnCreateOptionsMenu(IMenu menu)
{
MenuInflater.Inflate(Resource.Menu.menu_main, menu);
return true;
}
public override bool OnOptionsItemSelected(IMenuItem item)
{
switch (item.ItemId)
{
case Resource.Id.add_item:
Toast.MakeText(this, "You Clicked Add", ToastLength.Short).Show();
break;
case Resource.Id.remove_item:
Toast.MakeText(this, "You Clicked Remove", ToastLength.Short).Show();
break;
default:
break;
}
return true;
}
Effect.
Update :
You can change the color of the MenuItem text by using SpannableString, for example :
public override bool OnOptionsItemSelected(IMenuItem item)
{
switch (item.ItemId)
{
case Resource.Id.add_item:
Android.Text.SpannableString s = new Android.Text.SpannableString(item.ToString());
s.SetSpan(new ForegroundColorSpan(Color.Blue), 0, s.Length(), 0);
item.SetTitle(s);
break;
...
}
}

How to change a boolean value in onOptionsItemMenuSelected Android

I've got an options menu that allows the user to change map type on google maps. That works fine, but I'd like to offer the functionality to change the markers presently showing which I control with a boolean value. Here is my current code.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.menu.map_styles_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
switch(item.getItemId()) {
case R.id.normal_map:
mapType=GoogleMap.MAP_TYPE_NORMAL;
break;
case R.id.satellite_map:
mapType=GoogleMap.MAP_TYPE_SATELLITE;
break;
case R.id.terrain_map:
mapType=GoogleMap.MAP_TYPE_TERRAIN;
break;
case R.id.hybrid_map:
mapType=GoogleMap.MAP_TYPE_HYBRID;
break;
}
googleMap.setMapType(mapType);
return true;
}
I guess what I'd like to do is create another case statement like so
case R.id.present:
mapChange=true;
break;
case R.id.past:
mapChange=false;
break;
I use items in the menu XML file to represent the maps, could I use items for changing a boolean too?
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/map_types"
android:title="Menu"
android:showAsAction="always">
<menu>
<item android:id="#+id/normal_map"
android:title="Mormal map"/>
<item android:id="#+id/satellite_map"
android:title="Satellite map"/>
<item android:id="#+id/terrain_map"
android:title="Terrain map"/>
<item android:id="#+id/hybrid_map"
android:title="Hybrid map"/>
</menu>
</item>
So I would add an item below the above like
<item android:id="#+id/past"
android:title="Change to past markers"/>

First of all I would suggest to try everything that you think can work. And if still not finding an answer then post on SO.
With the explanation that you have mentioned and with my limited knowledge I conclude that you need one option in your option menu which will toggle between your markers screen and other markers screen.
So add the option in your xml:
<item android:id="#+id/past"
android:title="Change to past markers"/>
then in your java file add this code:
case R.id.past:
if(mapChange){
mapChange=false;
//your code to show other markers
}else{
mapChange=true;
//your code to show same markers etc
}
break;

Well if you want you can just create another method named "changeState()" and put your suggested switch case in that method
Private void changeState() {
Switch(VARIABLE-HERE)
{
case R.id.present:
mapChange=true;
break;
case R.id.past:
mapChange=false;
break;
}
}
And call it after.
googleMap.setMapType(mapType);

how to highlight action bar item select in android

I am creating an app wherein I have three items in the action bar. I want that when I click on one of the item, it should get highlighted.
I went through few examples available but concluded that I will have to create style using
ActionBar Style Generator tool.
I referred the following link.. but was not satisfied
how to highlight a menu item on selection?
Is this the only way to go about?
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:actionBarItemBackground">#drawable/action_bar_item_selector</item>
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_focused="true"
android:drawable="#drawable/ic_action_blue" />
<item android:state_pressed="true"
android:drawable="#drawable/ic_action_green" />
<item android:drawable="#android:color/transparent" />
</selector>
But the selection does not remain stagnant as it is for state_pressed and state_focused.
I want the item to remain highlighted till the user is on that activity.

More elegant way of handling the issue , is to simply have a boolean value that will check
both states , If you are using the same drawable with different state colors , i will recommend
you to use the colorFilter method to apply to your drawables.
private boolean mSomeValue = true;
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// determine the menu item you want to highlight when selected
switch(item.getItemId) {
case yourItem : {
if (mSomeValue) {
item.getIcon().setColorFilter(YourColor, PorterDuff.Mode.MULTIPLY);
mSomeValue = false;
} else {
mSomeValue = true;
item.getIcon().setColorFilter(Default, PorterDuff.Mode.MULTIPLY);
}
break; ...
}
}
return super.onOptionsItemSelected(item);
}

You can define a theme and inherit the Action bar theme you want (for instance Theme.Sherlock.Light.DarkActionBar), set the value of the android:actionBarItemBackground attribute to override the default one in the inheritted theme.
<style name="MyTheme" parent="Theme.Sherlock.Light.DarkActionBar">
<item name="android:actionBarItemBackground">custom_selector</item>
</style>

I am creating an app wherein I have three items in the action bar. I
want that when I click on one of the item, it should get highlighted.
I am not sure if the following will work properly:
Create two sets of icons for each of the menu items: one for the default look, the other highlighted (in whatever way you feel: change the color, change the background color etc.). Declare a global Menu variable to hold the menu item:
// Global variable // Not good practice, but needed in this case
Menu mainMenu;
....
....
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_name, menu);
mainMenu = menu;
return true;
}
In onMenuItemSelected(int featureId, MenuItem item):
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
for (int i = 0; i < mainMenu.size(); i++) {
// Set default icons
if (mainMenu.getItem(i).getItemId() == R.id.action1) {
mainMenu.getItem(i).setIcon(R.drawable.icon_default1);
} else if (mainMenu.getItem(i).getItemId() == R.id.action2) {
mainMenu.getItem(i).setIcon(R.drawable.icon_default2);
} else if (.....) {
.....
}
}
if (item.getItemId() == R.id.action1) {
item.setIcon(R.drawable.icon_highlighted1);
} else if (item.getItemId() == R.id.action2) {
item.setIcon(R.drawable.icon_highlighted2);
} else if(.....) {
.....
}
return super.onMenuItemSelected(featureId, item);
}
I guess you can fine-tune this by checking against item.getItemId() inside the for-loop itself.

Ok, so i suggest you to create two different items in your menu.xml:
<item
android:id="#+id/action_item1"
/>
<item
android:id="#+id/action_item2"
android:visible="false"
/>
Then, in the activity in which you want to highlight your item, override the ononPrepareOptionsMenu , use the menu paremeter to catch your desired item by using the menu.findItem(R.id.your_item_id). And finally toggle the visibility of your items.
You will need to refresh your action bar items automatically by using invalidateOptionsMenu
Let me know if that helps !

Android action bar checkable menu item does not work/show properly?

so I am trying to get my menu item, that is show on the action bar to behave like a checkable menu option. The firs part works, meaning it is checkable and when I press it, and set in code the setChecked(true) it works. But what does not work is the visual part. There is no change in how a menu item looks on the action bar in checked and unchecked states? I tried using invalidateOptionsMenu() but that does not do the job, and not only that, with that line in my code I can't get out of the checked state?!?
What happens is that invalidate OptionsMenu() seams to unset the checked state and I end up 'looping', or on every press of that menu item I keep going to the unchecked part of the code where it gets checked and with invalidate it gets unchecked I guess...
Here is the code from my XML file for menu:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/lenslist_menu_add"
android:showAsAction="always"
android:title="#string/add"/>
<item android:id="#+id/lenslist_menu_delete"
android:showAsAction="always"
android:checkable="true"
android:title="#string/delete"/>
</menu>
And here is the java code:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.lenslist_menu_add:
return true;
case R.id.lenslist_menu_delete:
if (item.isChecked() == true) {
item.setChecked(false);
deleteMode = false;
lensAdapter.setDeleteMode(false);
} else {
item.setChecked(true);
deleteMode = true;
lensAdapter.setDeleteMode(true);
}
lensAdapter.notifyDataSetChanged();
return true;
}
return super.onOptionsItemSelected(item);
}
Thanks!

Checkable items appear only in submenus or context menus.
You are using them as main menu items, hence it will not work.
SOURCE: Download the API DEMOS, and open the file ApiDemos/res/menu/checkable.xml, you'll see it as a comment on line 13. I don't know why they don't mention this in the Developer Documentation
reference with comment.:
http://alvinalexander.com/java/jwarehouse/android-examples/platforms/android-2/samples/ApiDemos/res/menu/checkable.xml.shtml

Or just do it yourself
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
menu.findItem(R.id.item1).setIcon(menu_checked?R.drawable.menu_ico_checked:R.drawable.menu_ico_unchecked);
return super.onPrepareOptionsMenu(menu);
}
and in onOptionsItemSelected do:
....
menu_checked=!menu_checked;
invalidateOptionsMenu();

The best solution is to set the actionLayout of the <Item> to a CheckBox. This solution gives you a native-looking checkbox (with material animations etc), with a font that matches the other items, and it works both as an action and in the submenu.
Create a new layout called action_checkbox.html:
<?xml version="1.0" encoding="utf-8"?>
<CheckBox xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingStart="8dp"
android:paddingEnd="8dp"
android:checked="false"
android:textAppearance="#android:style/TextAppearance.DeviceDefault.Widget.ActionBar.Menu"
android:id="#+id/action_item_checkbox"
/>
Set your <Item> like this. Note that you need the Checkable and Checked still in case it is shown in a sub-menu (in which case the actionLayout is ignored.
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity">
<item android:id="#+id/menu_action_logging"
android:title="#string/action_logging"
android:orderInCategory="100"
android:showAsAction="always"
android:checkable="true"
android:checked="false"
android:actionLayout="#layout/action_checkbox"
/>
</menu>
In your code, when the menu is created we need to a) set the title of the checkbox to match the menu item title, b) restore the checked state of both the menu checkable, and our extra checkbox, and c) add an onClicked() listener for our extra checkbox. In this code I am persisting the state of the checkbox in a RetainedFragment.
// Set the check state of an actionbar item that has its actionLayout set to a layout
// containing a checkbox with the ID action_item_checkbox.
private void setActionBarCheckboxChecked(MenuItem it, boolean checked)
{
if (it == null)
return;
it.setChecked(checked);
// Since it is shown as an action, and not in the sub-menu we have to manually set the icon too.
CheckBox cb = (CheckBox)it.getActionView().findViewById(R.id.action_item_checkbox);
if (cb != null)
cb.setChecked(checked);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
inflater.inflate(R.menu.menu_main, menu);
super.onCreateOptionsMenu(menu, inflater);
// Restore the check state e.g. if the device has been rotated.
final MenuItem logItem = menu.findItem(R.id.menu_action_logging);
setActionBarCheckboxChecked(logItem, mRetainedFragment.getLoggingEnabled());
CheckBox cb = (CheckBox)logItem.getActionView().findViewById(R.id.action_item_checkbox);
if (cb != null)
{
// Set the text to match the item.
cb.setText(logItem.getTitle());
// Add the onClickListener because the CheckBox doesn't automatically trigger onOptionsItemSelected.
cb.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(logItem);
}
});
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_action_logging:
// Toggle the checkbox.
setActionBarCheckboxChecked(item, !item.isChecked());
// Do whatever you want to do when the checkbox is changed.
mRetainedFragment.setLoggingEnabled(item.isChecked());
return true;
default:
break;
}
return false;
}

Android Checkable Menu Item

I have the following menu layout in my Android app:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/item1"
android:titleCondensed="Options"
android:title="Highlight Options"
android:icon="#android:drawable/ic_menu_preferences" />
<item android:id="#+id/item2"
android:titleCondensed="Persist"
android:title="Persist"
android:icon="#android:drawable/ic_menu_preferences"
android:checkable="true" />
</menu>
My problem is that the second menu item doesn't appear to be "checkable" when I run my app in the Android emulator. There should be a green tick about the item, right? To indicate that its checkable.
Am I doing something wrong?

Layout looks right. But you must check and uncheck menu item in code.
From the documentation:
When a checkable item is selected, the system calls your respective item-selected callback method (such as onOptionsItemSelected()). It is here that you must set the state of the checkbox, because a checkbox or radio button does not change its state automatically. You can query the current state of the item (as it was before the user selected it) with isChecked() and then set the checked state with setChecked().

Wrap the items in a group element, like this:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="all">
<item android:id="#+id/item1"
android:titleCondensed="Options"
android:title="Highlight Options"
android:icon="#android:drawable/ic_menu_preferences">
</item>
<item android:id="#+id/item2"
android:titleCondensed="Persist"
android:title="Persist"
android:icon="#android:drawable/ic_menu_preferences"
android:checkable="true">
</item>
</group>
</menu>
From the Android docs:
The android:checkableBehavior attribute accepts either:
single - Only one item from the group can be checked (radio buttons)
all - All items can be checked (checkboxes)
none - No items are checkable

You can create a checkable menu item by setting the actionViewClass to a checkable widget like android.widget.CheckBox
res/menu/menu_with_checkable_menu_item.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_favorite"
android:checkable="true"
android:title="#string/action_favorite"
app:actionViewClass="android.widget.CheckBox"
app:showAsAction="ifRoom|withText" />
</menu>
And you can can even style it to be a checkable star if you set actionLayout to a layout with a styled android.widget.CheckBox
res/layout
/action_layout_styled_checkbox.xml
<CheckBox xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/starStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
res/menu/menu_with_checkable_star_menu_item.xml
<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:checkable="true"
android:title="#string/action_favorites"
app:actionLayout="#layout/action_layout_styled_checkbox"
app:showAsAction="ifRoom|withText" />
</menu>
To set the value
menuItem.setChecked(true/false);
To get the value
menuItem.isChecked()
Cast MenuItem to CheckBox
CheckBox checkBox= (CheckBox) menuItem.getActionView();

I've found that the best solution was to just use the onOptionsItemSelected() method as of my current API (27-28).
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
//Copy from here...
int itemId = item.getItemId();
if(item.isChecked())
{
if(R.id.edit_tile_checkbox == itemId) //Individual checkbox logic
{ /*TODO unchecked Action*/}
item.setChecked(false); //Toggles checkbox state.
}
else
{
if(R.id.edit_tile_checkbox == itemId) //Individual checkbox logic
{/*TODO checked Action*/}
item.setChecked(true); //Toggles checkbox state.
}
//...To here in to your onOptionsItemSelected() method, then make sure your variables are all sweet.
return super.onOptionsItemSelected(item);
}
I spent way to long on here for this answer. and for whatever reason, the answers above didn't help (I'm a returning newbie I probably mucked something up I'm sure).
There could be a better way of doing this so helpful criticism is welcomed.

READ THIS
As has been said the "manual checking" is only the tip of the iceberg. It flashes the menu away so fast the users don't see anything happen and it is very counter intuitive, frustrating, and effectively utter crap. The REAL TASK (therefore) is allowing the check box event to be digested by the users mind.
Good news: this can be done and it does work and this is how you do it. #TouchBoarder had it best so I will copy his code. then develop it.
the idea is to detect if the checkbox is clicked, then (and only if that one is picked) slightly suppress the menu removal, add a timer for 500ms then close the menu, this give the "tick" animation of the checkbox time to run and creates the right "feel"
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_favorite"
android:checkable="true"
android:title="#string/action_favorite"
app:actionViewClass="android.widget.CheckBox"
app:showAsAction="ifRoom|withText" />
</menu>
then you make this method as usual, but you make sure you add all this extra bumpf
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the bottom bar and the top bar (weird)
BottomAppBar bottomBar = findViewById(R.id.bottom_app_bar_help);
Menu bottomMenu = bottomBar.getMenu();
getMenuInflater().inflate(R.menu.bottom_nav_menu, bottomMenu);
for (int i = 0; i < bottomMenu.size(); i++) {
bottomMenu.getItem(i).setOnMenuItemClickListener(item -> {
if (item.getItemId()==R.id.action_favorite){
item.setChecked(!item.isChecked());
// Keep the popup menu open
item.setShowAsAction(MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
item.setActionView(new View(frmMain.this));
item.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
final Handler handler = new Handler();
handler.postDelayed(() -> bottomMenu.close(), 500);
return false;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
final Handler handler = new Handler();
handler.postDelayed(() -> bottomMenu.close(), 500);
return false;
}
});
return false;
}
else {
return onOptionsItemSelected(item);
}
});
}
return true;
}
the other menu events are here
public boolean onOptionsItemSelected(MenuItem item) {
// Bottom Bar item click
try {
switch (item.getItemId()) {
case R.id.mnuExit:
MenuClick(ClickType.LOGOUT);
return true;
case R.id.mnuList:
MenuClick(ClickType.LIST);
return true;
default:
return super.onOptionsItemSelected(item);
}
} catch (Exception e) {
e.printStackTrace();
}
return super.onOptionsItemSelected(item);
}

Answering because the answers here seem long and convoluted.. I have some exact Kotlin code here
Override your activity at the top and override the function onMenuItemClick, Have a function to handle the button click to open the menu.
Have an array or list which holds the checked value and sets the check when the menu is re-created
Note: This code does not keep the menu open, It only ensures that checked items remain checked.
I noted there are lots of solutions to that on stack overflow, so have a look at them if that's what you desire
class exampleActivity : AppCompatActivity(), PopupMenu.OnMenuItemClickListener {
private var checkChecked = arrayListOf(false,false)
//some code
fun clickBTN(v: View){
val popup = PopupMenu(this,v)
popup.setOnMenuItemClickListener(this)
popup.inflate(R.menu.yourmenufilename)
//assuming you have 2 or more menu items
popup.menu[0].isChecked = checkChecked[0]
popup.menu[1].isChecked = checkChecked[1]
popup.show()
}
override fun onMenuItemClick(item: MenuItem?): Boolean {
when(item?.itemID){
R.id.item0 -> {
item.isChecked = !item.isChecked
checkChecked[0] = item.isChecked
return true
}
R.id.item1 -> {
item.isChecked = !item.isChecked
checkChecked[1] = item.isChecked
return true
}
}
}
of course in XML you should have your Button and Menu setup. An example menu is here
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/item0"
android:title="#string/hi"
android:checkable="true"/>
<item android:id="#+id/item1"
android:title="#string/yo"
android:checkable="true"/>
</menu>

This may be theme dependant but my menu didn't show a checkbox. I found this :
Note: Menu items in the Icon Menu cannot display a checkbox or radio
button. If you choose to make items in the Icon Menu checkable, then
you must personally indicate the state by swapping the icon and/or
text each time the state changes between on and off.

For Adding Menu items Programmatically,
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add("Item1").setActionView(R.layout.action_layout_checkbox).setCheckable(true);
return super.onCreateOptionsMenu(menu);
}
res/layout /action_layout_checkbox.xml
<CheckBox xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

I have two items in the menu and set to checkable in menu.xml file like below
<item
android:id="#+id/A"
android:title="A"
app:showAsAction="never"
android:checkable="true"/>
<item
android:id="#+id/B"
android:title="B"
app:showAsAction="never"
android:checkable="true"/>
and logic for the menu checkboxes is below.
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.A:
//logic goes here
if(item.isChecked())
{
//logic is it is checked
item.setChecked(false);
}
else
{
//logic is it is not checked
item.setChecked(true);
}
return true;
case R.id.B:
//logic for second checkbox goes here
if(item.isChecked())
{
//logic is it is checked
item.setChecked(false);
}
else
{
//logic is it is not checked
item.setChecked(true);
}
return true;
default:
return super.onOptionsItemSelected(item);
}
