AppCompatActivity instead of ComponentActivity in Jetpack compose


I want to open datePicker dialog on a button click in Jetpack compose.
For that, I am using the below code inside the button's onClick action.

val context = LocalContext.current
Button(onClick = {
    (context as AppCompatActivity).let {
        val picker = MaterialDatePicker.Builder.datePicker().build()
        picker.show(it.supportFragmentManager, picker.toString())
        picker.addOnPositiveButtonClickListener {
            // some code
        }
    }
})

If I am using the ComponentActivity, supportFragmentManager is not supported.
Is it fine to extend the activity from AppCompatActivity?
Or is there any other way, I can get the solution if the above-mentioned solution is not correct?


Solution

  • You can use the AppCompatActivity since it extends FragmentActivity which extends ComponentActivity.

    class MainActivity : AppCompatActivity() {
    
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
    
            setContent {
               val activity = LocalContext.current as AppCompatActivity
                    Button(onClick={ showDatePicker(activity)}){
                    Text("Picker")
               }
            }
        }
    }
    
    fun showDatePicker(activity: AppCompatActivity){
        val picker = MaterialDatePicker.Builder.datePicker().build()
        activity?.let {
            picker.show(it.supportFragmentManager, picker.toString())
            picker.addOnPositiveButtonClickListener {
            }
        }
    }
    

    Note: it requires at least the AppCompat 1.3.0 version.
