java - Android:异常解码未知类型

我必须将ArrayList从一个活动传递到另一个活动。所以我用

intent.putParcelableArrayListExtra("Items",sendinglist);

我通过发送列表

ArrayList<GeoItem> revd = new ArrayList<GeoItem>();
        Bundle b = getIntent().getExtras();
        if (b != null)
            revd = b.getParcelableArrayList("Items");
Log.i("Element details",revd.get(0).getLatitude()+"");// Error

但是我无法访问该列表中的GeoItem对象。
根据答案更新课程...

我的GeoItem类是

公共类GeoItem实现了Parcelable，Serializable {

/** id of item. */
protected long id_;
/** item location in GeoPoint. */
// protected GeoPoint location_;
/** selection state flag. true if selected. */

请提供给我最好的方法...

最佳答案

GeoPoint不是Parceable，因此可以将其编组。您可能想以某种方式保存数据而不使用GeoPoint或扩展GeoPoint以便它实现Parceable
