How to prevent popup menu from closing on checkbox click

Question

I search a lot on net but there is nothing about preventing popup menu from closing.

Whenever i click on checkbox item or any other popup menu item, popup menu dismiss itself. How can i prevent it from dismissing when user check/uncheck checkbox in popup menu.

I'm showing popup menu on actionbar-menu item's click event.

//main_menu.xml
<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"
tools:context="com.worldofjobs.woj.MainActivity" >

<item
    android:id="@+id/action_popUpMenu"
    android:icon="@drawable/ic_action_overflow"
    android:title="@string/main_action_popUpMenu"
    app:showAsAction="always"/>

</menu>

//popup_items.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@+id/refresh_item"
    android:title="@string/main_refresh"/>
<item
    android:id="@+id/checkbox_item"
    android:checkable="true"
    android:title="Start notification"/>
<item
    android:id="@+id/changePasswrod_item"
    android:title="@string/main_changePassword"/>
<item
    android:id="@+id/deleteAccount_item"
    android:title="@string/main_deleteAccount"/>
<item
    android:id="@+id/logout_item"
    android:title="@string/main_logout"/>

</menu>

/**

private void showPopup() {

    try {

        View v = findViewById(R.id.action_popUpMenu);

        PopupMenu popup = new PopupMenu(this, v);
        popup.setOnMenuItemClickListener(MainActivity.this);

        MenuInflater inflater = popup.getMenuInflater();
        inflater.inflate(R.menu.pop_items, popup.getMenu());
        popup.show();

    } catch (Exception e) {

        Log.e("MainActivity-showPopup:", e.toString());
    }
}

/**

@Override
public boolean onMenuItemClick(MenuItem item) {

    super.onMenuItemSelected(1, item);
    switch (item.getItemId()) {

    case R.id.refresh_item:
        refresh();
        return true;

    case R.id.checkbox_item:
        return true;

    case R.id.changePasswrod_item:
        changePasswordPopup();
        return true;

    case R.id.deleteAccount_item:
        deleteAccount();
        return true;

    case R.id.logout_item:
        session.logout();
        finish();
        return true;
    }
    return true;
}

Using popupMenu.show() to immediately re-show the popup menu does not work correctly with checkable menu items when changing their checked states.

Here a method that prevents closing the popup menu in the first place. Make sure that onMenuItemClick returns false.

popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
    @Override
    public boolean onMenuItemClick(MenuItem item) {

        item.setChecked(!item.isChecked());

        // Do other stuff

        // Keep the popup menu open
        item.setShowAsAction(MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
        item.setActionView(new View(context));
        item.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                return false;
            }

            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                return false;
            }
        });
        return false;
    }
});
