首先，您必须使显示此类对话框的功能

WITH ORDERED AS (
 SELECT
  *,
  ROW_NUMBER() OVER(ORDER BY age ASC) AS ROWNUM
FROM
  `data`
)
SELECT
  age AS percentile50
FROM
  ORDERED
WHERE
  ROWNUM = (
    SELECT CEILING(50 / 100.00 * (COUNT(*) + 1)) FROM ORDERED
  )

然后在gridview项单击中调用此函数。

public void showDialog(){  

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    LayoutInflater inflater = getLayoutInflater();
    final View dialogView = inflater.inflate(R.layout.dialog_menu, null);
    final AlertDialog dialog = builder.create();
    dialog.setView(dialogView);
    dialog.show();
 }
