灌水 无聊的别来 别搞事情
我就想花C找人帮忙解决问题 丢一句话的你就别发了 没有代码 你也别发了
多看下我的问题描述 你有好的方法也可以贴代码给我看
我想说一下我写的东西的功能 就是在一个有很多imagebutton的页面 点击一个imagebtn 通过Switch 选择后 在新的页面输出对应的
图片 和 文字描述 。文字的描述是通过数据库查找出来的！
我现在已经实现了图片传递 ，但是文字查询传递我还没有实现
我的想法是 定义一个方法
public String query（int i）{
Cursor cursor = db.rawQuery("select content from car ");
然后定义一个数组 将cursor查询到的内容存入数组
再通过query（ int i ）给的i找到数组对应的内容
最后return
}
如果是我的想法 有问题 希望大佬能告诉下这个该用什么方法解决 顺便写一下方法代码
全部代码
