      // in your activity or fragment
      AlertDialog.Builder builder = new AlertDialog.Builder(this);
      
      builder.setTitle("Sample Alert");
      builder.setMessage("This is a simple alert box");
      
      // Add the buttons
      builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int id) {
      // User clicked OK button
      }
      });
      builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int id) {
      // User cancelled the dialog
      }
      });
      
      // Create the AlertDialog
      AlertDialog dialog = builder.create();
      
      // show the dialog
      dialog.show();
