[android] ArrayAdapter in android to create simple listview

But again main doubt why TextView resource id it needs?

Look at the constructor and the params.

public ArrayAdapter (Context context, int resource, int textViewResourceId, T[] objects)

Added in API level 1 Constructor

Parameters

context The current context.

resource The resource ID for a layout file containing a layout to use when instantiating views.

textViewResourceId The id of the TextView within the layout resource to be populated objects The objects to represent in the ListView.

android.R.id.text1 refers to the id of text in android resource. So you need not have the one in your activity.

Here's the full list

http://developer.android.com/reference/android/R.id.html

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1, android.R.id.text1, values);

this refers to activity context

android.R.layout.simple_list_item_1 simple_list_item_1 is the layout in android.R.layout.

android.R.id.text1 refers to the android resource id.

values is a string array from the link you provided
