title: Custom ListView - cannot instantiate the type ListAdapter
body: <p>I have this code:</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.main);
     ListView lv = (ListView) findViewById(R.id.lvResult);
     ListAdapter listAdapter = new ListAdapter(Prueba.this, imageList, list1, list2);
     lv.setAdapter(listAdapter);
  }
  </code></pre>
  
  <p>And it gives an Error:<br>
  <code>Cannot instantiate the type ListAdapter</code></p>
  
  <p>In the same package, I have created a class called <code>ListAdapter.java</code> with its code.<br>
  I don't know what that error means.</p>
