Changing Action Bar Menu Item Icon When Pressed in Android Studio

Question

I am working on this simple Android application. I have three Menu Items on the Action Bar and each of the menu items inflate 3 different fragments when clicked on them.

My Question: When I click on one of the Menu Items, I want that Menu Item's icon changing to another icon in the drawables folder and STAY like that until I click on another Menu Item and then it will change to the first icon before I clicked on it.

I tried to use a selector .xml with "state_pressed" and when I click on the Menu Item it changes the icon for a second but then it goes back to the first icon as soon as I stop clicking. You can find the related codes below. I'd appreciate it if you could help me with this one.

submenu.xml (Action Bar Menu):

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" >
    <item
        android:id="@+id/action_todo"
        android:title=""
        android:icon="@drawable/action_bar_selector"
        app:showAsAction="always" />
</menu>

action_bar_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:drawable="@drawable/ic_check_box_white_24dp"
        android:state_pressed="true" />
    <item
        android:drawable="@drawable/ic_check_box_white_24dp_unpressed" />
</selector>

ProjectTodo.java (Inflating Action Bar in Fragment Class):

public void onCreateOptionsMenu(Menu menu, MenuInflater inflater){
    inflater.inflate(R.menu.submenu, menu);
}

public boolean onOptionsItemSelected(MenuItem item){
    int id = item.getItemId();
    if(id == R.id.action_back){
        ProjectDetails frag = new ProjectDetails();
        ProjectMainListFragmentChanger fragInterface = (ProjectMainListFragmentChanger) getActivity();
        fragInterface.projectMainListChangeFragment(frag);
        return false;
    }

    if(id == R.id.action_details){
        return true;
    }

    if(id == R.id.action_todo){
        ProjectDetails frag = new ProjectDetails();
        ProjectTodoFragmentChanger fragInterface = (ProjectTodoFragmentChanger) getActivity();
        fragInterface.projectTodoChangeFragment(frag);      
        return false;
    }
    return super.onOptionsItemSelected(item);
}

You can see a quick .gif image of the current application. When I click on the Menu Item, it only changes to the 2nd icon for a second and then goes back to its original icon:

If you just want to toggle the item you can do so using onOptionsItemSelected and onPrepareOptionsMenu

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    boolean result = true;
    switch (item.getItemId()) {
        case R.id.menu_details_save_toggle:
            if (mIsSaved) { //you could modify this to check the icon/text of the menu item
                mIsSaved = false;
            } else {
                mIsSaved = true;
            }
            invalidateOptionsMenu(); //cause a redraw
            break;
        default:
            result = super.onOptionsItemSelected(item);

    }
    return result;
}

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    if (mIsSaved) {
        //in production you'd probably be better off keeping a reference to the item 
        menu.findItem(R.id.menu_details_save_toggle)
            .setIcon(R.drawable.action_saved_on)
            .setTitle(R.string.action_unsave);
    } else {
        menu.findItem(R.id.menu_details_save_toggle)
            .setIcon(R.drawable.action_saved_off)
            .setTitle(R.string.action_save);
    }
    return super.onPrepareOptionsMenu(menu);
}

As Simple as it goes !!

ToobarActivity.class:

    public class ToolbarActivity extends AppCompatActivity {

    private Menu menu;// Global Menu Declaration

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_toolbar);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

        setSupportActionBar(toolbar);


        //This is my Back Button View onClick on toolbar
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        this.menu = menu;
        getMenuInflater().inflate(R.menu.main_menu, menu);


        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //This is the Answer to your problem
        if (id == R.id.actionsignout) {
            menu.getItem(1).setVisible(true);
            menu.getItem(0).setVisible(false);
            return true;
        }else if (id == R.id.action) {
            menu.getItem(0).setVisible(true);
            menu.getItem(1).setVisible(false);
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {



        return super.onPrepareOptionsMenu(menu);
    }
}

On res/menu/main_menu.xml:

Set the second item Visibility to false

<?xml version="1.0" encoding="utf-8"?>

<item android:id="@+id/actionsignout"
    app:showAsAction="always"
    android:icon="@drawable/ic_pause_black_24dp"
    android:title="Sign Out"/>

<item android:id="@+id/action"
    app:showAsAction="ifRoom"
    android:visible="false" 
    android:icon="@drawable/ic_play_arrow_black_24dp"
    android:title=""/>
