当单击
ImageView时,我想从listView中删除某行.我的清单看起来像这样:
我想要的是当最后一个图像被点击删除该行.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; } }
我试图用这个删除行:
listView.removeView(v); myadapter.notifyDataSetChanged();
我收到错误:ERROR AndroidRuntime java.lang.UnsupportedOperationException:AdapterView不支持removeView(View)
我的秘密在哪里?任何想法?
