drawable states won't update on action bar

I have an action bar which contains an item shuffle_action.
I have used below case in the onOptionsItemSelected(MenuItem item) function.
switch (item.getItemId()){
case R.id.action_shuffle:
if(MusicService.shuffle) {
item.setChecked(false);
Toast.makeText(this,String.valueOf(item.isChecked()),
Toast.LENGTH_SHORT).show();// returns false
musicService.clearShuffle();
}
else {
item.setChecked(true);
Toast.makeText(this,String.valueOf(item.isChecked()),
Toast.LENGTH_SHORT).show();// returns true
}
musicService.setShuffle();
break;
}
Now this thing works perfectly as i want it to work.
<item
android:id="#+id/action_shuffle"
android:icon="#drawable/shuffle_drawable"
android:title="Shuffle"
app:showAsAction="ifRoom"
android:checkable="true"
android:checked="false"
/>
shuffle_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#drawable/shuffle_pressed"/>
<item
android:state_checked="false"
android:drawable="#drawable/ic_shuffle_black_18dp"/>
</selector>
The thing is that when the state changes the drawable won't change.Why is this happening?

Action Bar Menu Items Duplicating on Run

I am very new to Java Programming and Android Studio.
While creating an Options Menu, I created a list of options in the main menu with two items in a group sub menu.
This is my menu.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/giveup_setting"
android:orderInCategory="1"
app:showAsAction="ifRoom"
android:title="#string/action_option1"/>
<item
android:id="#+id/new_game_setting"
android:orderInCategory="2"
app:showAsAction="never"
android:title="#string/action_option2"/>
<item
android:id="#+id/help_setting"
android:orderInCategory="3"
app:showAsAction="never"
android:title="#string/action_option3"/>
<item
android:id="#+id/settings_setting"
android:orderInCategory="4"
app:showAsAction="never"
android:title="#string/action_option4" />
<menu>
<group android:checkableBehavior="single">
<item
android:id="#+id/menu_color"
android:orderInCategory="1"
app:showAsAction="never"
android:title="#string/layout_color"/>
<item
android:id="#+id/menu_text"
android:orderInCategory="2"
app:showAsAction="never"
android:title="#string/layout_text"/>
</group>
</menu>
<item
android:id="#+id/about_setting"
android:orderInCategory="5"
app:showAsAction="never"
android:title="#string/action_option5"/>
<item
android:id="#+id/exit_setting"
android:orderInCategory="6"
app:showAsAction="never"
android:title="#string/action_option6"/>
</menu>
An this is how I inflate the menu in my MainActivity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
menu.clear();
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem menu) {
// Handle item selection
switch (menu.getItemId()) {
case R.id.help_setting:
//show help screens
return true;
case R.id.menu_color:
//change a layout of my main activity
return true;
case R.id.menu_text:
//change another layout of my main activity
return true;*/
case R.id.about_setting:
//show my about screen
return true;
case R.id.giveup_setting:
//resets the game
case R.id.new_game_setting:
//restarts the app
return true;
case R.id.exit_setting:
//exits the app
return true;
default:
return super.onOptionsItemSelected(menu);
}
}
On running the app, the menu populates but the "Settings" item (which has the nested group radio buttons) displays twice.

What am I doing wrong?

if android:id="#+id/settings_setting" is the one you want to have a submenu don't close the item tag. Instead inflate <menu> inside the <item> tag.
<item
android:id="#+id/settings_setting"
android:orderInCategory="4"
app:showAsAction="never"
android:title="#string/action_option4">
<menu>
<group android:checkableBehavior="single">
<item
android:id="#+id/menu_color"
android:orderInCategory="1"
app:showAsAction="never"
android:title="#string/layout_color"/>
<item
android:id="#+id/menu_text"
android:orderInCategory="2"
app:showAsAction="never"
android:title="#string/layout_text"/>
</group>
</menu>
</item>

Deeply nested menu items do not fire on click - Android

It may be worth noting that my R.java file disappeared this morning because I used an incorrect menu icon name in this menu XML file. I have since corrected the name and regenerated the R.java file.
What I have found out by debugging:
Any menu item that takes 4 clicks to get to does not fire the onOptionsItemSelected listener in Android.
Can I make these 4-click menuItems fire the onOptionsItemSelected listener? Thanks.

Nest your <items> of the second level of <menu> into <group>, for example:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu1"/>
<item android:id="#+id/menu2">
<menu>
<group android:id="#+id/group2">
<item android:id="#+id/submenu1" />
<item android:id="#+id/submenu2" />
</group>
</menu>
</item>
</menu>

From the Android documentation on menus:
You can add a submenu to an item in any menu (except a submenu) by
adding a <menu> element as the child of an <item>

Having trouble adding extra items to my options menu Android

A the moment I have this options menu
I would like to add to options at the bottom below hybrid map. Here is my code. I have added in where I would like the two other menu options to be but they don't work.
#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;
case R.id.games2014:
games2014=true;
break;
case R.id.games_past:
games2014=false;
break;
}
googleMap.setMapType(mapType);
return true;
}
<?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"/>
<Item android:id="#+id/games2014"
android:title="2014 Games"/>
<Item android:id="#+id/games_past"
android:title="Previous Games"/>
</menu>
</item>

In your item you declared it as Item which would cause it not to add
#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;
case R.id.games2014:
games2014=true;
break;
case R.id.games_past:
games2014=false;
break;
}
googleMap.setMapType(mapType);
return true;
}
<?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="Hybrid map"/>
<item android:id="#+id/games2014"
android:title="2014 Games"/>
<item android:id="#+id/games_past"
android:title="Previous Games"/>
</menu>
</item>

<Item android:id="#+id/games2014"
android:title="2014 Games"/>
<Item android:id="#+id/games_past"
android:title="Previous Games"/>
Your "I" in "Item" is capital. It should be a lowercase "i" - "item"

handle clicks on submenus in android

I am new to android and stuck at the point where i have to detect clicks on submenus that are defined in XML file
my XML file is :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/ccard_menu1"
android:title="Select from Profile?"
></item>
<item android:id="#+id/ccard_menu2"
android:title="Add Field"
>
<menu >
<item android:id="#+id/submenu1"
android:title="Add Products"
></item>
<item android:id="#+id/submenu2"
android:title="Add Clients"
></item>
<item android:id="#+id/submenu3"
android:title="Add a Custom Field">s</item>
</menu>
</item>
</menu>
how do i detect clicks on "submenu 1,2,3" in onOptionsItemSelected method?
how do i have to structure the switch case?

I you are looking for something like this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.your_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.submenu1:
// do something
return true;
case R.id.submenu2:
//do something else
return true;
// etc..
default:
return super.onOptionsItemSelected(item);
}
}
Please correct me if I am mistaken.
