title: Fatal error Spinner and ArrayAdapter
body: <p>I have this part of code for spinner. But  I get fatal error. What is wrong in here? Thanks! My Activity extends FragmentActivity.</p>
  
  <pre><code>                Spinner spinner;
                  String[] layers = {getString(R.string.a), getString(R.string.b), getString(R.string.c)};
  
                  LayoutInflater li = LayoutInflater.from(this);
                  View v;
                  v  = li.inflate(R.layout.nearest, null);
  
                  ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(MyActivity.this, android.R.layout.simple_spinner_item, layers);
                  spinner = (Spinner) findViewById(R.id.spinner_nearest);
                  spinner.setAdapter(adapter);
  
  
                  AlertDialog.Builder builder = new AlertDialog.Builder(this);
                  builder.setView(v);
  
                  builder.setCancelable(true);
                  AlertDialog alert = builder.create();
                  alert.show();}
