How do i show suggessions in AutoCompleteTextView Android?

Question

there

I have an problem like suggestions not showing automatically in AutoCompleteTextView,

So what is my flow?

1. I added an com.google.android.material.textfield.MaterialAutoCompleteTextView
2. initialize the variable in Kotlin using binding.
3. Set empty Adapter to MaterialAutoCompleteTextView
4. now i implement an logic in MaterialAutoCompleteTextView
   • If user input an word, after 1 second i hit an api for suggestions
   • i got success in fetching suggestions in API
   • where i got suggestions, there i notify MaterialAutoCompleteTextView adapter

Problem

- I did not show any suggestions in `MaterialAutoCompleteTextView`
- but i fetch suggestions successfully

If i remove one character or type one character then it show APIs suggestions properly

What is my requirement

• i need to show suggestions automatically when API fetch suggestions successfully
• do not wanna using

autoCompletetextView.text = autoCompletetextView.text.toString()

What i tried

• showDropDown()
• performCompletion()
• adapter.notifyDataSetChange()
