I’ve been trying to figure how the ArrayAdapter class can be used, and from the docs : http://developer.android.com/reference/android/widget/ArrayAdapter.html, I see the constructor expects an integer called textViewResourceId.

What is this exactly?

Edit:
From a little more research and the answers here, it looks like it must be the id of a TextView that I defined in the xml file that contains the interface code. But I saw this example here:

ArrAdapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,myArrayList)

So how can android.R.layout.simple_list_item_1 be used here? What does this mean really? I am only familiar with using R.id.idOfMyViewHere

    it is the id of the textview in which the adapter will update the info you will provide. You can use textview provided by android:

    android.R.id.text1

    for instance. Or you can provide your own textView whit your custom id

    Edit

    change:

    ArrayAdapter(this,android.R.layout.simple_list_item_1,myArrayList)

    with

    ArrayAdapter(this,android.R.id.text1,myArrayList)
