override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    val inflater = menuInflater
    super.onCreateOptionsMenu(menu)
    inflater.inflate(R.menu.main_menu, menu)

    val manager = getSystemService(Context.SEARCH_SERVICE) as SearchManager
    val searchItem = menu?.findItem(R.id.search)
    val searchView = searchItem?.actionView as SearchView
    searchView.setSearchableInfo(manager.getSearchableInfo(componentName))
    searchView.setOnQueryTextListener(object : SearchView.OnQueryTextListener {
        override fun onQueryTextSubmit(query: String?): Boolean {
            searchView.clearFocus()
            searchView.setQuery("", false)
            searchItem.collapseActionView()
            Toast.makeText(this@MainActivity, "looking for $query", Toast.LENGTH_LONG).show()
            return true
        }

i have this in the main activity. if I want to reuse this(it's a search bar on the actionbar) in another activity, do i have to copy and paste the code every time? or is there an easier/efficient way to do this?

[Steve]

The suggested way would probably be to see if you can combine those activities into one, so you don't have to duplicate, and have the contents be fragments

[Steve]

if that's not possible, I would suggest trying to take the search view stuff and try to make it an independent component, so you just have to instantiate it

[ZariApps]

@Steve - its different screens so can i have fragments with different screens. i am just started to build so wont be a lot of rework. need to read up on fragments since idk how to do that just yet

[Steve]

the general suggestion nowadays is to only use activities where they're absolutely needed, and use fragments everywhere else

[ZariApps]

good to know. i'll read up on fragments so i can leverage

[Ian Lake]

I'd strongly suggest starting with Navigation rather than raw fragments: https://developer.android.com/guide/navigation

[Ian Lake]

And check out the Navigation code lab for a hands on approach for how it works: https://codelabs.developers.google.com/codelabs/android-navigation/

[ZariApps]

are there any youtube videos you recommend?

[Ian Lake]

That first link has an overview video right at the top, plus a ton of video links at the bottom

[ZariApps]

@Ian Lake im going to try this but i dont have a buttom navigation. i only have a top action bar with the app name, a search icon and a menu option list

[ZariApps]

is that okay?

[Ian Lake]

Yep

[ZariApps]

great, going to try now

[ZariApps]

thanks

[ZariApps]

@Steve read up on fragments, it's a lot harder to code than activities it seems. will keep learning

[Colton Idle]

@ZariApps I agree with what Ian said. The "Navigation" architecture component makes it dead easy to work with fragments.

[ZariApps]

Yeah I am pretty new so I'm learning and implimeting slowly. It seems to be successful so far!

[ZariApps]

@Steve @Ian Lake with fragments, its is possible to change menus?

[ZariApps]

so if you're in one fragment, one menu and when you go to another, another menu?

[Ian Lake]

I mean, that's how it works automatically - fragments on the back stack won't have their menu items displayed

[ZariApps]

so i have the title of the page youre on in teh menu

[ZariApps]

right now, all of them are showing the same title

[ZariApps]

@Ian Lake

[Ian Lake]

Did you read the documentation on how to set up the top bar with Navigation? It specifically points out how to set a label for each destination https://developer.android.com/guide/navigation/navigation-ui#top_app_bar

[ZariApps]

oh shoot no sorry. i have been youtubing to learn and completely forgot abotu that link

[ZariApps]

i will read now!

[ZariApps]

im a visual learner sorry

[ZariApps]

@Ian Lake it works!!!

[ZariApps]

thank you so much man

[ZariApps]

sorry i didnt read your document earlier lol

[ZariApps]

quick question though, my titles of the toolbars are not good

[ZariApps]

meaning they are like the schema names

[ZariApps]

trying to fix, i think i know how

[ZariApps]

yup got it, updating the label in the navigation

[ZariApps]

this is awesomeeeeeeeeeee

[ZariApps]

i literally started learning a week ago and i have a pretty good understanding now. thank you to everyone who has helped me

[ZariApps]

@Ian Lake @Steve @Colton Idle

[Colton Idle]

Good luck! The docs sometimes still seem to escape me, but its nice that people will point you in the right direction.

[ZariApps]

any reason my menu wont show up in the toolbar?

[ZariApps]

override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    val inflater = menuInflater
    super.onCreateOptionsMenu(menu)
    inflater.inflate(R.menu.main_menu, menu)

[ZariApps]

return true

[Ian Lake]

Does your fragment call setHasOptionsMenu(true) (say, in onCreate())?

[ZariApps]

current focus is on the title menu and no, i dont see that anywhere

[ZariApps]

let me try adding it

[Ian Lake]

That is a requirement as per the Javadoc: https://developer.android.com/reference/androidx/fragment/app/Fragment?hl=en#onCreateOptionsMenu(android.view.Menu,%20android.view.MenuInflater)

[ZariApps]

added it, no luck. let me read the doc

[ZariApps]

setSupportActionBar(toolbar)

i was missing this

[ZariApps]

i converted my actionbar into a toolbar and i guess didnt set that

[Ian Lake]

Yeah, the fragment menu APIs plug into the ActionBar

[ZariApps]

@Ian Lake thanks again man. you're the best

[Ian Lake]

Just make sure to use the instructions on the Action Bar part of the Navigation UI page as they do differ quite a bit from the Toolbar that isn't an ActionBar instructions

[ZariApps]

will keep an eye out. i am facing a UI error when i click on the search box and click on menu option and backout, it removes the search icon

[ZariApps]

image.png,image.png,image.png,image.png

[ZariApps]

see search icon gone....

[ZariApps]

and search option shoes up in menu when it shouldnt

[ZariApps]

<item
    android:id="@+id/search"
    android:icon="@drawable/ic_search_black_24dp"
    android:title="@string/search"
    app:actionViewClass="androidx.appcompat.widget.SearchView"
    app:showAsAction="ifRoom|collapseActionView" />

[ZariApps]

@Ian Lake can you help?

[Ian Lake]

Probably a better stack overflow question

[ZariApps]

will ask, thank you
