Android, Toolbar 생성

1. Actionbar 제거

• 프로젝트 전체 ActionBar 없애기

<application android:theme = "@style/Theme.AppCompat.Light.NoActionBar"/>

<reosource xmlns:tools="http://schemas.android.com/tools">
	<!-- Base application theme. -->
	<style name = "Theme.IntoDig" parent = "Theme.MaterialComponents.DayNight.DarkActionBar">
		<!-- chande parent -> ...DayNight.NoActionBar -->
		<!-- Primary brand color. -->
		<item name = "colorPrimary">@color/purple_500</item>
		<item name = "colorPrimary">@color/purple_700</item>

• 일부 Activity에만 적용하는 경우

1) style - parent

<style name = "Themename" parent "Theme.AppCompat.NoActionBar">
	<item name = "android:windowBackground">@color/white</item>
</style>

2) item

<style name = "Theme.intoDig.NoActionBar">
	<item name = "windowActionBar">false</item>
	<item name = "windowNoTitle">true</item>
</style>

3) example(Fullscreen, No Actionbar)

<resources>
	<style name = "AppTheme" parent = "Theme.AppCompat.Light.DarkActionBar">
		<item name = "windowActionBar">false</item>
		<item name = "windowNoTitme">true</item>
		<item name = "android:windowFullscreen">false</item>
	</style>
</resources>

4) Manifest로 가서 적용할 activity에 theme추가

<activity
	android:name = ".ui.chatting.ChattingAcitivity"
	android:exported = "false"
	android:theme = "@style/Theme.intoDig.NoActionBar"
	android:windowSoftInputMode="adjustUnspecified"/>

2. Toolbar를 넣을 Activity의 xml파일로 가서 toolbar 추가

AppBarLayout: Toolbar를 포함하여 Toolbar이외에 액티비팉 상단을 조금 더 넓게 구성하거나 이미지를 포함하는 등 다양하게 구성할 수 있음

<com.google.android.material.appbar.AppBarLayout
	android:layout_width = "match_parent"
	android:layout_height="wrap_content"
	android:theme = "@style/Theme.intoDig.AppBarOverlay"
	app:elevation = "8dp"
	app:layout_constraintEnd_toEndOf="parent"
	app:layout_constraintStart_toStartOf="parent"
	app:layout_constraintTop_toTopOf="parent"

	<androidx.appcompat.widget.Toolbar
		android:id = "@+id/toolbar"
		android:layout_width = "match_parent"
		andorid:layout_height = "?attr/actionBarSize"
		android:background="?attr/colorPrimary/>
</com.google.android.material.appbar.AppBarLayout>

3. Toolbar가 있는 Activity에 Toolbar 선언

val toolbar = binding.Toolbar.toolbar
setSupportActionBar(toolbarBodyTemplate)
supportActionBar?.setDisplayHomeAsUpEnabled(true) // 뒤로가기 버튼 활성화
supportActionBar?.setDisplaySHowTitleEnabled(false) // 액션바에 표시되는 제목 표시여부. flase를 해야 custom한것 표시

4. Toolbar menu연결

<?xml version"1.9" encoding="utf-8"?>
<menu xmls:android="http://schemas.android.com/apk/res/android"
	xmlns:app = "http://schemas.android.com/apk/res-auto">
	<item
		android:id="@+id/toolbar_info"
		app:showAsAction = "always"
		android:icon="@drawable/ic_information_white_30"
		android:title="@string/title_addchat" />
</menu>

5. Toolbar menu 클릭 이벤트 설정

override fun onOptionsItemSeleted(item:MenuItem): Boolean {
	when(item.itemId) {
		android.R.id.home ->{ // 뒤로가기 버튼
			finish()
		}
		R.id.toolbar_info -> { // 툴팁
			val view = findVIewById<R.id.toolbar_info) //  툴팁 띄우기 위해서는 view가 필요함
	    balloon.showAlignBottom(view)
		}
	}
	return super.onOptionItemSeleted(item)
}
