我引用并使用Etsy StaggeredGridView将来自json的数据从AsyncTask加载到GridView中的路径:http://www.technotalkative.com/lazy-productive-android-developer-part-6-staggered-gridview/

1。在StaggeredGridActivity类中,我尝试更改数据类型:

从:

private ArrayList<String> mData;    

private ArrayList<HashMap<String, String>> mData;

2。在SampleAdapter类中,我尝试更改:

从:

    public class StaggeredAdapter extends ArrayAdapter<String> {
    ...
       public StaggeredAdapter(Context context, int textViewResourceId,
                     ArrayList<String> objects) {
       super(context, textViewResourceId, objects);
       ...
       }
    ...
    }

    public class StaggeredAdapter extends ArrayAdapter<HashMap<String,String>> {
    ...
       public StaggeredAdapter(Context context, int textViewResourceId,
                     ArrayList<HashMap<String,String>> objects) {
       super(context, textViewResourceId, objects);
       ...
       }
    ...
    }

然后,似乎StaggeredAdapter类中有一个例外:

ImageLoader.getInstance().displayImage(getItem(position), vh.imgView);
带警报的

Cannot resolve method 'displayImage(java.util.HashMap<java.lang.String,java.lang.String>,com.etsy.android.grid.util.DynamicHeightImageView)'

如何修复和更改ArrayList的数据类型为HashMap

谢谢!
