Question

我有一个由我的MainActivity实现的ListFragmentA（它也覆盖onListItemClick并且是必需的）。 CustomArrayAdapter有两个图像和3个textViews。一切正常，除非我制作我的一个图像“Clickable = onEditDelete”。在ListFragmentA中找不到onEditDelete方法，但在将方法移动到MainActivity时找到了IS。

我想了解为什么会这样？一旦图像被点击，它是否不再属于ListFragment？
如果方法只能在MainActiviy中找到，那么获取单元格中单击图像索引的最佳方法是什么？

- 感谢你。

public class MainActivity extends BaseActivity  {

    public void goEditDelete(View ed) {

                Log.d("myLog", "edit ******************* Item prod clicked:  ");
    }

}




public class CustomListViewAdapter extends ArrayAdapter<RowItem> {

    Context context;

    public CustomListViewAdapter(Context context, int resourceId, List<RowItem> items) {
        super(context, resourceId, items);
        this.context = context;
    }

    /*private view holder class*/
    private class ViewHolder {
        ImageView imageView;
        TextView txtTitle;
        TextView txtSubTitle;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        RowItem rowItem = getItem(position);

        LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);

        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.row, null);
            holder = new ViewHolder();

            holder.txtTitle = (TextView) convertView.findViewById(R.id.row_title);
            holder.txtSubTitle = (TextView) convertView.findViewById(R.id.row_subTitle);
            holder.imageView = (ImageView) convertView.findViewById(R.id.row_icon);  // make clickable ****************
            convertView.setTag(holder);
        } else
            holder = (ViewHolder) convertView.getTag();

        holder.txtSubTitle.setText(rowItem.getsubTitle());
        holder.txtTitle.setText(rowItem.getTitle());
        holder.imageView.setImageResource(rowItem.getImageId());

        return convertView;
    }
}




public class MainView extends SherlockListFragment  {

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);


        // chekc data before hand
        Log.e("myLog", "SAVED Data1 ListSize = " + myProdArrayHash.size());


        for (int i = 0; i < myProdArrayHash.size(); i++) {

            Log.e("myLog", "SAVED DataLoooop = "+ myProdArrayHash.get(i).toString());
        }
        //
        // Keys used in Hashmap
        String[] from = {"editIcon", "prod", "dist", "repEmail","repPhone"};

        // Ids of views in listview_layout
        int[] to = {R.id.row_icon, R.id.row_title, R.id.row_subTitle, R.id.tvRepEmail, R.id.tvRepCell};

        // Instantiating an adapter to store each items

        adapter = new SimpleAdapter(getActivity(), myProdArrayHash, R.layout.row, from, to);

        // Getting a reference to listview of main.xml layout file

        setListAdapter(adapter);




        // double heck
         Log.d("myDataCheck_storedItems", " sizeOfCurrentData() MainViewFrag onStart() END= " + sizeOfCurrentData());

    }
}

在xml中声明的单击方法总是转到活动。从来没有碎片。多数民众赞成如何设计。

您必须手动将事件转发到您的片段。在onClick-method活动中（无论你在xml中声明了什么），都可以对你的片段进行反馈并在那里调用一个公共方法。
