title: Get View from ListView
body: <p>I have to find the coordinates of a ImageView inside my ListView but I can't make it. I have tried with getItemAtPosition() but the APP crashes. Each ImageView has a different tag and in each row of my ListView. </p>
  
  <p>My function:</p>
  
  <pre><code>ListView listStudents = (ListView) findViewById(R.id.listStudents);
  View view = (View) listStudents.getItemAtPosition(0);
  </code></pre>
  
  <p>This is my ListViewAdapter:</p>
  
  <pre><code>private ArrayList&lt;HashMap&lt;String,String&gt;&gt; list = new ArrayList&lt;HashMap&lt;String,String&gt;&gt;();
  
  
  public ListViewAdapter(Context context, ArrayList&lt;HashMap&lt;String,String&gt;&gt; items) {
       mContext = context;
       this.list = items;
  }
  
  public int getCount() {
