Hi guys.

I have a question here.
I have a BaseActivity which has the showProgressBar(visibility: Boolean) function, this will toggle the ProgressBar visibility based on the value.

Then, I have a RecipeListActivity which extends BaseActivity that will send the boolean data type in the showProgressBar when the button is clicked.

BaseActivity .kt

fun showProgressBar(visibility: Boolean) {
    progressBar.visibility = if (visibility) View.INVISIBLE else View.VISIBLE
}

RecipeListActivity.kt

activity_content.test.setOnClickListener(View.OnClickListener { view ->
    val visibility = view.visibility != View.VISIBLE
    showProgressBar(visibility)
})

But right now the value of the visibility in the showProgressBar is showing 8 or 0 instead of true or false.

Did I miss out anything?

val visibility = !(view.visibility == View.VISIBLE)

That does not help. Lol.

[suhas]

sorry 🙂

[Ayden]

No problem.

View.VISIBLE and View.INVISIBLE are constants under the hood, so it makes sense that you’re seeing “0” and “8” as values in the debugger! Here’s a stack overflow post about similar: https://stackoverflow.com/questions/8636133/whats-the-difference-of-setvisibilityview-invisible-setvisibility0
