如何在“x”秒后显示数组值？

Question

我有一个sql查询，它检索两个数据行并将其设置为数组列表。另一方面，我获取该数据并显示在Toast.it上显示第一行数据，之后显示第二行数据。工作正常。但我想做的是当吐司显示第一行数据时，它应该暂停“x”秒并显示第二个数据。

这是我的SQL查询

public ArrayList<Content> getContent(String todayid){
        ArrayList<Content> dataArr=new ArrayList<Content>();

        SQLiteDatabase db = handler.getWritableDatabase();
        String query="select mname from content where schid='"+todayid+"'";
        Cursor c = db.rawQuery(query, null);

        try {

            while (c.moveToNext()) {
                String name = c.getString(c.getColumnIndex(DBHandler.MEDIA_NAME));          
                Content content=new Content();
                content.setmName(name);
                dataArr.add(content);
            }

        }catch (Exception e){

        }
        return dataArr;
    }

这是获得sql结果和显示

 public void getContent(String todayid){

 try {
     ScreenDetailsFunc db=new ScreenDetailsFunc(Screen.this);
     final ArrayList<Content> content=db.getContent(todayid);
     for (final Content data:content){
    Toast.makeText(getApplicationContext(),data.getmName()+"",Toast.LENGTH_LONG).show();
                }
}catch (Exception e){

                    }
    }

数据库值

我的“todayid”是16.i将“2.jpg，3.png”添加到数组
