我想用select查询从表中检索数据。我已发现，SQLiteDatabase类rawQuery（查询，selectionArgs两个）方法检索数据。但我不知道如何查询和selectionArgs两个应该传递给rawQuery方法？任何人可以帮助我。

在此先感谢。

  rawQuery（SELECT ID，名称从不同人的名字=？和id =？，新的String [] { 大卫，2}）;
 

您传递一个字符串数组相同数量的元素，你有？

I want to use select query for retrieving data from table. I have found, rawQuery(query, selectionArgs) method of SQLiteDatabase class to retrieve data. But I don't know how the "query" and "selectionArgs" should be passed to rawQuery method? Can anybody help me.

Thanks in advance.

rawQuery("SELECT id, name FROM people WHERE name = ? AND id = ?", new String[] {"David", "2"});

You pass a string array with an equal number of elements as you have "?"
