## Usage
- Create menu.xml under your res/menu/ folder
```xml
```
- Add view into your layout file
```xml
```
- Use SmoothBottomBar callbacks in your activity
```kotlin
bottomBar.onItemSelected = {
status.text = "Item $it selected"
}
bottomBar.onItemReselected = {
status.text = "Item $it re-selected"
}
```
OR
```kotlin
bottomBar.setOnItemSelectedListener(object: OnItemSelectedListener {
override fun onItemSelect(pos: Int) {
status.text = "Item $pos selected"
}
})
bottomBar.setOnItemReselectedListener(object: OnItemReselectedListener {
override fun onItemReselect(pos: Int) {
status.text = "Item $pos re-selected"
}
})
```
>**Note:** For projects without kotlin, you may need to add `org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion` to your dependencies since this is a Kotlin library.
## **Use SmoothBottomBar with [Navigation Components](https://developer.android.com/guide/navigation/).**
Coupled with the Navigation Component from the [Android Jetpack](https://developer.android.com/jetpack), SmoothBottomBar offers easier navigation within your application by designating navigation to the Navigation Component. This works best when using fragments, as the Navigation component helps to handle your fragment transactions.
- Setup Navigation Component i.e. Add dependenccy to your project, create a Navigation Graph etc.
- For each Fragment in your Navigation Graph, ensure that the Fragment's `id` is the same as the MenuItems in your Menu i.e res/menu/ folder
```xml
```
Navigation Graph i.e res/navigation/ folder
```xml
```
- In your activity i.e `MainActivity`, create an instance of `PopupMenu` which takes a `context` and an `anchor`(pass in null) and then inflate this `PopupMenu` with the layout menu for the `SmoothBottomBar`.
- Get a reference to your `SmoothBottomBar` and call `setupWithNavController()` which takes in a `Menu` and `NavController`, pass in the menu of the previously instantiated `PopupMenu` i.e.(`popUpMenu.menu`) and your `NavController`.
- Preferably set this up in a function as shown below and call this function i.e. (`setupSmoothBottomMenu()`) in the `onCreate` method of your activity.
**N.B:** Sample app makes use of [ViewBinding](https://developer.android.com/topic/libraries/view-binding) to get reference to views in the layout.
```kotlin
private fun setupSmoothBottomMenu() {
binding.bottomBar.setupWithNavController(navController)
}
```
### ActionBar
You can also setup your `ActionBar` with the Navigation Component by calling `setupActionBarWithNavController` and pass in your `NavController`.
**N.B:** Your app needs to have a `Toolbar` for `setupActionBarWithNavController` to work. If your app theme doesn't have a `Toolbar` i.e. (Theme.AppCompat.Light.NoActionBar) you would need to:
- Add one to your layout i.e.
```xml
```
- Set the support action bar to your `Toolbar` using `setSupportActionBar(your_toolbar_id)` in this case `setSupportActionBar(binding.toolBar)`
We now have something like this:
```kotlin
private lateinit var navController: NavController
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
navController = findNavController(R.id.main_fragment)
setupActionBarWithNavController(navController)
setupSmoothBottomMenu()
}
private fun setupSmoothBottomMenu() {
binding.bottomBar.setupWithNavController(navController)
}
//set an active fragment programmatically
fun setSelectedItem(pos:Int){
binding.bottomBar.setSelectedItem(pos)
}
//set badge indicator
fun setBadge(pos:Int){
binding.bottomBar.setBadge(pos)
}
//remove badge indicator
fun removeBadge(pos:Int){
binding.bottomBar.removeBadge(pos)
}
override fun onSupportNavigateUp(): Boolean {
return navController.navigateUp() || super.onSupportNavigateUp()
}
```
### Result Demo:
### Update [8th May, 2021]
Prior to the [initial addition of this feature](https://github.com/ibrahimsn98/SmoothBottomBar/pull/33), you can now inflate separate menu items for the `SmoothBottomBar` and your `Toolbar`.
- Create the menu item you want to inflate in the `Toolbar` i.e.
```xml
```
- Override `OnCreateOptionsMenu` and `onOptionsItemSelected` (ensure it returns `super.onOptionsItemSelected(item)`). Now we have:
```kotlin
class MainActivity : AppCompatActivity() {
private lateinit var navController: NavController
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
navController = findNavController(R.id.main_fragment)
setupActionBarWithNavController(navController)
setupSmoothBottomMenu()
}
override fun onCreateOptionsMenu(menu: Menu?): Boolean {
menuInflater.inflate(R.menu.another_menu, menu)
return true
}
override fun onOptionsItemSelected(item: MenuItem): Boolean {
when (item.itemId) {
R.id.another_item_1 -> {
showToast("Another Menu Item 1 Selected")
}
R.id.another_item_2 -> {
showToast("Another Menu Item 2 Selected")
}
R.id.another_item_3 -> {
showToast("Another Menu Item 3 Selected")
}
}
return super.onOptionsItemSelected(item)
}
private fun showToast(msg: String) {
Toast.makeText(this, msg, Toast.LENGTH_SHORT).show()
}
private fun setupSmoothBottomMenu() {
binding.bottomBar.setupWithNavController(navController)
}
//set an active fragment programmatically
fun setSelectedItem(pos:Int){
binding.bottomBar.setSelectedItem(pos)
}
//set badge indicator
fun setBadge(pos:Int){
binding.bottomBar.setBadge(pos)
}
//remove badge indicator
fun removeBadge(pos:Int){
binding.bottomBar.removeBadge(pos)
}
override fun onSupportNavigateUp(): Boolean {
return navController.navigateUp() || super.onSupportNavigateUp()
}
}
```
### Select Bottom Item from any fragment
```kotlin
buttonId.setOnClickListener {
(requireActivity() as MainActivity).setSelectedItem(2)
}
```
