如何通过它的价值，而不是当前位置设置微调默认？ [英] How to set Spinner Default by its Value instead of Postion?

问题描述

我有1-50记录在数据库中。我使用的游标，并设置这些值使用简单的游标适配器微调获取这些数据。现在，我需要的是我想设置一个值，说39的值作为默认值。但不是由它的位置，我想用它的值来设置。

I have 1-50 records in the database. I am fetching those data using cursor and set those values to Spinner using Simple Cursor Adapter. Now what i need is i want to set one value say 39th value as default. But not by its position i want to set by its value.

我知道如何通过它的位置设置微调默认

I know how to set the spinner default by its position

   spinner.setSelection(39) 

将设置微调器的值。

will set the spinner to that value.

但我确实没有关于它的数据库中的值（文本）设置微调默认的任何想法。 我知道在数据库中的值。对于如书是在微调的一个值。我需要设置微调默认的书籍。

But i didn't have any idea about setting the spinner default by its value(text) in the database. I know the values in the database. For eg "books" is one of the value in the spinner. I need to set the spinner default as books.

是否有任何可能的方式来做到这一点？

Is there any possible way to do this?

感谢您的帮助家伙...

Thanks for you help guys...

推荐答案

最后，我用下面的方法，其中微调的位置可以通过它的字符串得到解决的问题

Finally, i solved the problem by using following way, in which the position of the spinner can be get by its string

private int getPostiton(String locationid,Cursor cursor)
{
    int i;
    cursor.moveToFirst(); 
    for(i=0;i< cursor.getCount()-1;i++)
    {  

        String locationVal = cursor.getString(cursor.getColumnIndex(RoadMoveDataBase.LT_LOCATION));  
        if(locationVal.equals(locationid))
        { 
            position = i+1;  
            break;
        }
        else
        {
            position = 0;
        }
        cursor.moveToNext();  
    } 

调用方法

    Spinner location2 = (Spinner)findViewById(R.id.spinner1);
    int location2id = getPostiton(cursor.getString(3),cursor);
    location2.setSelection(location2id);

我希望这将有助于为一些一..
