android – Best practice to asynchronously delete a ListView/RecyclerView item

Best option in your case will be using RecyclerView. Because when you clicked delete you can call adapter.notifyItemRemoved(itemPos). So the list item will be removed with animation from your RecyclerView and you will not worry about the delete operation result.

See the Android Developer tutorial on Creating Lists and Cards:

Use the RecyclerView widget when you have data collections whose
elements change at runtime based on user action or network events.

Here is an example:

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> implements View.OnClickListener, View.OnLongClickListener {

private ArrayList<String> mDataset;
private static Context sContext;

public MyAdapter(Context context, ArrayList<String> myDataset) {
    mDataset = myDataset;
    sContext = context;
}

@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.my_text_view, parent, false);

    ViewHolder holder = new ViewHolder(v);
    holder.mNameTextView.setOnClickListener(MyAdapter.this);

    holder.mNameTextView.setTag(holder);

    return holder;
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {

    holder.mNameTextView.setText(mDataset.get(position));

}

@Override
public int getItemCount() {
    return mDataset.size();
}


@Override
public void onClick(View view) {
    ViewHolder holder = (ViewHolder) view.getTag();
    if (view.getId() == holder.mNameTextView.getId()) {
        **//Important !!!**
        notifyItemRemoved(getPosition());
        // Make your database operation also here
    }
}



public static class ViewHolder extends RecyclerView.ViewHolder {
    public TextView mNumberRowTextView;
    public TextView mNameTextView;


    public ViewHolder(View v) {
        super(v);

        mNameTextView = (TextView) v.findViewById(R.id.nameTextView);
    }
}

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final View itemView = convertView != null ? convertView : /* inflate view */;
        itemView.findViewById(R.id.delete_button).setOnClickListener(
                new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        itemView.setEnabled(false);
                        // OR view.setClickable(false);
                    }
                });
        return itemView;
    }

Or use RecyclerView with removal animation.

if your database query is not returning lot of data then there is no issue to do database operations on UI thread.
