How to use this two ArrayAdapter constructor
<p>When I read the API doc, I found 2 weird constructor in ArrayAdapter class:</p>

<pre><code>public ArrayAdapter (Context context, int textViewResourceId)

public ArrayAdapter (Context context, int resource, int textViewResourceId)
</code></pre>

<p>There is no List or Array to insert into this 2 public constructor (the rest has), then what are the purpose to have these 2 constructor? How to use them?</p>
