Infinite loop while switch button isChecked-CodePudding

I am fairly new to kotlin and was wondering if there was to infinitely run a loop when a switch button is in the isChecked state. My code is as follows :

binding.switch1.setOnCheckedChangeListener { _, isChecked ->

        if(isChecked) {
            P1 = true
            try {
                while(P1) {
                    for (i in 0..10) {
                        Log.d(TAG, "The iterator number is $i")
                    }
                }
            } catch (e: NullPointerException) {
                Log.d(TAG, "Hii")

            }
        }
        else{
            try{
                // break while loop

            } catch(e: NullPointerException){

            }
        }

While the button is in the isChecked state, I want the loop to continuously loop the for loop. Thankyou in advance for the help!1

CodePudding user response：

This problem occurs when one process block the MAIN thread (or UI thread) the of problem is ANR, to solve this, you can run this process in another thread(ex: Coroutines).

example :

CoroutineScope(Dispatchers.IO).launch {
  try {
    while(true) {
       //the logic here 
    }
  } catch (e: NullPointerException) {}
 }

But, be careful when you access the view components in this thread because need a little treatment for this.
