inline fun SearchView.onQueryTextChanged(crossinline listener: (String) -> Unit) {
    this.setOnQueryTextListener(object : SearchView.OnQueryTextListener {
        override fun onQueryTextSubmit(query: String?): Boolean {
            return true
        }

        override fun onQueryTextChange(newText: String?): Boolean {
            listener(newText.orEmpty())
            return true
        }
    })
}

Do I understand that correctly, the crossinline modifier assures that we can't call return in the lambda we are passing to this function? Because if we don't call return here, we would leave the onQueryTextChange method.

Return from onQueryTextChange should not happen iirc, but always do Tools -> Kotlin -> Show Kotlin Bytecode -> Decompile to Java for complete sure(ity). Create a check with a test lambda and decompile !

[Florian]

I decompiled the code but I don't understand it

[Florian]

that's why I'm asking for a verification of my understanding

Yep, the compiler prevents the passed listener to have suspend calls and return expressions. listener can still throw theoretically though.

thank you
