现在修改代码以反映已接受的解决方案.

现在,这是一个如何将自定义ArrayList传递给DialogFragment的工作示例.

我正在使用newInstance上的Bundle将自定义对象的ArrayList传递给DialogFragment.在newInstance中正确接收了arraylist.对putParcelable的调用执行正常(无错误),但在ArrayList对象的parcelable代码中放置断点表明在设置或获取数据时未调用parcel方法.

我是否正确为ArrayList创建一个LocalityList类并使其成为parcelable,或者Locality类本身是否可以分类？

DialogFragment

/**
 * Create a new instance of ValidateUserEnteredLocationLocalitySelectorFragment, providing "localityList"
 * as an argument.
 */
public static ValidateUserEnteredLocationLocalitySelectorFragment newInstance(LocalityList localityList) {

    ValidateUserEnteredLocationLocalitySelectorFragment fragmentInstance = new ValidateUserEnteredLocationLocalitySelectorFragment();

    // Supply location input as an argument.
    Bundle bundle = new Bundle();
    bundle.putParcelable(KEY_LOCALITY_LIST, localityList);
    fragmentInstance.setArguments(bundle);

    return fragmentInstance;
}


/**
 * Retrieve the locality list from the bundle
 */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mLocalityList = getArguments().getParcelable(KEY_LOCALITY_LIST);
}


 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) { …

我试图将此主要活动的数据传递给另一个活动

我成功地在活动之间发送数据....就像从Edit-text到下一个活动的数据,putExtra以及GetExtra方法和传递作为意图

• 但是我在这个特殊任务中面临挑战,它涉及将数据从listview发送到普通活动
• 数据在JSON的列表视图中填充,因此在单击一行时如何将该行的数据发送到新活动

有任何想法吗,
