title: Show alertDialog with radiobuttons when click a listViewItem
body: <p>I have a listView with 2 items in it, the 2 items are "seconds" and "minutes"
  When I press "seconds" I'd like a alertDialogBox to open en show 5,10,15,... seconds. Same when I press minutes</p>
  
  <p>Something like this:</p>

  <p>But I'm having trouble implementing it, because I don't understand very well how it is working. Here is the code I have:</p>
  
  <pre><code>import android.app.Activity;
  import android.app.AlertDialog;
  import android.content.DialogInterface;
  import android.os.Bundle;
  import android.view.View;
  import android.widget.AdapterView;
  import android.widget.AdapterView.OnItemClickListener;
  import android.widget.ArrayAdapter;
  import android.widget.ListView;
  import android.widget.Toast;
  
  public class SettingsActivity extends Activity {
  
      ListView listView = (ListView) findViewById(R.id.settingsList);
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.settings);
  
          String[] values = new String[] { "Seconds", "Minutes" };
  
          // Define a new Adapter
          // First parameter - Context
          // Second parameter - Layout for the row
          // Third parameter - ID of the TextView to which the data is written
          // Forth - the Array of data
  
          ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this,
                  android.R.layout.simple_list_item_1, android.R.id.text1, values);
  
          // Assign adapter to ListView
          listView.setAdapter(adapter);
  
          listView.setOnItemClickListener(new OnItemClickListener() {
              public void onItemClick(AdapterView&lt;?&gt; arg0, View arg1,
                      int position, long arg3) {
                  AlertDialogView();
              }
          });
  
      }
  
      private void AlertDialogView() {
          final CharSequence[] items = { "15 secs", "30 secs", "1 min", "2 mins" };
  
          AlertDialog.Builder builder = new AlertDialog.Builder(ShowDialog.this);//ERROR ShowDialog cannot be resolved to a type
          builder.setTitle("Alert Dialog with ListView and Radio button");
          builder.setSingleChoiceItems(items, -1,
                  new DialogInterface.OnClickListener() {
                      public void onClick(DialogInterface dialog, int item) {
                          Toast.makeText(getApplicationContext(), items[item],
                                  Toast.LENGTH_SHORT).show();
                      }
                  });
  
          builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
              public void onClick(DialogInterface dialog, int id) {
                  Toast.makeText(ShowDialog.this, "Success", Toast.LENGTH_SHORT)
                          .show();
              }
          });
  
          builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
              public void onClick(DialogInterface dialog, int id) {
                  Toast.makeText(ShowDialog.this, "Fail", Toast.LENGTH_SHORT)
                          .show();
              }
          });
  
          AlertDialog alert = builder.create();
          alert.show();
      }
  }
