を使用し、これを試してみてください。

public class TestingActivity extends Activity { 

    AlertDialog alert; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     final CharSequence[] items = { "Red", "Green", "Blue" }; 

     final AlertDialog.Builder builder = new AlertDialog.Builder(this); 

     builder.setTitle("Pick a color"); 



     builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() { 

      public void onClick(DialogInterface dialog, int item) { 

       Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show(); 
         dismiss(); 
      } 

     }); 
     alert = builder.create(); 

     alert.show(); 
    } 

    private void dismiss() { 
     alert.dismiss(); 

    } 
    }
