Question 36

Which of the following is true about object arrayAdapter declared in the code below?

String[] items = {"Item 1","Item 2","Item 3"};

ArrayAdapter arrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, items); listView.setAdapter(arrayAdapter);

It creates a TextView for each String in array items.

It creates Buttons for each String in array items.

It creates four views for listView.

It replaces the layout of the activity with three consecutive TextView items.

Correct Answer: A

ArrayAdapter is used to adapt an array of data (in this case, strings) into views that can be displayed in a ListView. Specifically, ArrayAdapter uses a specified layout (here, android.R.layout.simple_list_item_1) to create a view for each item in the array. The layout android.R.layout.simple_list_item_1 contains a TextView, so the ArrayAdapter will create a TextView for each String in the array items.
