Question

我想从gridview中选择图像的属性。例如，如果我正在使用。

    GridView gridview = (GridView) findViewById(R.id.imageGallery);
    gridview.setAdapter(new ImageAdapter(this));

    gridview.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View v, int position,long id)
    {
         //need code in here that I can do something like this.
         //Get access to the integer value of the R.drawable.myimage
         //use that int too do a lookup in a dictionary to check for existance
         //can't see to find any code to get at the drawable associated with the image clicked in the grid, did intense debug

数据在运行时不易显示

    }
    );

@Reid我想你会想要根据列表中的位置创建一个自定义适配器（扩展BaseAdapter或其他），它包含一个包含你需要获取的元数据的视图类。可能是一种更简单的方法，但这就是我在ListView中所做的。几个链接：

需要访问android gridview中所选项目的图像
