推荐答案

使用

public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
        int imageId = (( ImageAdapter)parent.getAdapter()).mygetItemId(position);

        }
    }); 

在适配器类中添加此功能

in adapter class add this function

public long getItemId(int position) {
        return imagearray[position];
    }
