How to store data on Android Room Database without any button?

How to save data in Android Room Database without clicking any button? For example: on Samsung notes, we just need to write text on the title or body and notes are saved automatically without clicking any button on it. do I have to use one of the listeners?

If you want consistent autosave, you really should use RxJava or Kotlin Coroutines (even better) as Room fully supports them. You'll need to add either one of these dependencies:

implementation "androidx.room:room-ktx:$room_version"
implementation "androidx.room:room-rxjava2:$room_version"
implementation "androidx.room:room-rxjava3:$room_version"

Then, you can schedule your coroutine to save to Room for every 5 minutes or any interval you like.

P.S. For Kotlin Coroutines, use withContext(NonCancellable) to guarantee your data gets saved when your activity/application is destroyed.

You can add TextChangeListener to the EditText and put logic of adding data to the afterTextChanged() method like this way.

binding.editText.addTextChangedListener(object :TextWatcher{

        var timer: CountDownTimer? = null
        override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {

        }

        override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {

        }

        override fun afterTextChanged(s: Editable?) {
            timer?.cancel()
            timer = object : CountDownTimer(1000, 1500) {
                override fun onTick(millisUntilFinished: Long) {}
                override fun onFinish() {
                    //Put your data storing code here
                }
            }.start()
        }
    })

And you can change time interval as per your requirement.

You can save data in onDestroy() of your view, or add a textChangeListener and update your DB here (Not recommended!)
