android - AdapterView 不支持 removeView(View)

Question

我想在单击 ImageView 时从 listView 中删除特定行。我的 ListView 如下所示:

我希望在单击最后一张图像时删除该行。这是我的适配器:

public class UserItemAdapter extends ArrayAdapter<Photos.Record> {
        private ArrayList<Photos.Record> photos;

        public UserItemAdapter(Context context, int textViewResourceId, ArrayList<Photos.Record> photos) {
            super(context, textViewResourceId, photos);
            this.photos = photos;
        }

        @Override
        public View getView(final int position, View convertView, ViewGroup parent) {
            View v = convertView;


            if (v == null) {
                LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                v = vi.inflate(R.layout.photorowlist, null);
                                v.setClickable(true);
                                v.setFocusable(true);
            }

            Photos.Record user = photos.get(position);
            if (user != null) {
                TextView photo_name = (TextView) v.findViewById(R.id.photoname);

                if (photo_name != null) {
                    photo_name.setText(user.photo_name);
                }

            }
                        v.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View view) {
                            //Toast.makeText(view.getContext(), "Clicked", Toast.LENGTH_SHORT).show();

                            ImageView delete_photo = (ImageView) view.findViewById(R.id.deletephoto);
                            delete_photo.setOnClickListener(new OnClickListener(){  
                            @Override  
                            public void onClick(View v) {  
                                Toast.makeText(Photos.this, "Delete Button Clicked", Toast.LENGTH_SHORT).show();  
                                listView.removeView(v);
                                myadapter.notifyDataSetChanged();


              }});
                         }

                        });


            return v;
        }
    }

    public class Record {
        public String photo_name;

        public Record(String photo_name) {
            this.photo_name = photo_name;
        }
    }

我试着用这个删除行:

listView.removeView(v);
myadapter.notifyDataSetChanged();

我收到错误:ERROR AndroidRuntime java.lang.UnsupportedOperationException: removeView(View) is not supported in AdapterView

我的赌注在哪里？有什么想法吗？

Answer 1

您不必删除 View ，而是删除照片列表中的项目。

photos.remove(yourPhoto);
notifyDataSetChanged();

此外，你应该使用ViewHolders，谷歌有很多tuts。希望这对您有所帮助。
