java - ListView筛选器错误的结果

这是一个常见问题，但已解决的问题不适用于我的代码，因此我想粘贴自己的代码，因为我注意到Android开发有100万种方法来实现相同的结果，这有点困难，但无论如何...

每当我过滤列表视图时，过滤器之后都不会维护列表视图项的位置，过滤后的项将从0开始分配一个新位置，因此将位置0的原始列表视图项替换为该位置上的新归档项。

例如：listview = aONE [0], aTWO [1], aTHERE[2], bONE [3], b TWO[4], bTHREE [5].

如果输入“ b”，则新列表为

bONE [0], bTWO [1], bTHREE [2] and NOT bONE [3], bTWO [4], bTHREE [5],

下面是我的代码：

public class ListViewAdapterProduct extends BaseAdapter {

    // Declare Variables
    Context mContext;
    LayoutInflater inflater;
    private List<ClassProductList> classProductlist = null;
    private ArrayList<ClassProductList> arraylist;

    public ListViewAdapterProduct(Context context, List<ClassProductList> classProductlist) {
        mContext = context;
        this.classProductlist = classProductlist;
        inflater = LayoutInflater.from(mContext);
        this.arraylist = new ArrayList<ClassProductList>();
        this.arraylist.addAll(classProductlist);
    }

    public class ViewHolder {
        TextView title;
        TextView description;
        ImageView photo;
    }

    @Override
    public int getCount() {
        return classProductlist.size();
    }

    @Override
    public ClassProductList getItem(int position) {
        return classProductlist.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    public View getView(final int position, View view, ViewGroup parent) {
        final ViewHolder holder;
        if (view == null) {
            holder = new ViewHolder();
            view = inflater.inflate(R.layout.list_view_single_row, null);
            holder.title = (TextView) view.findViewById(R.id.textLarge);
            holder.description = (TextView) view.findViewById(R.id.textSmall);
            holder.photo= (ImageView) view.findViewById(R.id.imageThumb);
            view.setTag(holder);
        } else {
            holder = (ViewHolder) view.getTag();
        }
        holder.title.setText(classProductlist.get(position).getTitle());
        holder.description.setText(classProductlist.get(position).getDescription());
        holder.photo.setImageResource(classProductlist.get(position).getImage());

        view.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                if(position == 0) {
                    Intent intent0 = new Intent(mContext, ProductMyactivity1.class);
                    mContext.startActivity(intent0);
                }

                if(position == 1) {
                    Intent intent1 = new Intent(mContext, ProductMyactivity2.class);
                    mContext.startActivity(intent1);
                }
            }
        });

        return view;
    }

    // Filter Class
    public void filter(String charText) {
        charText = charText.toLowerCase(Locale.getDefault());
        classProductlist.clear();
        if (charText.length() == 0) {
            classProductlist.addAll(arraylist);
        }
        else
        {
            for (ClassProductList Product : arraylist)
            {
                if (Product.getTitle().toLowerCase(Locale.getDefault()).contains(charText))
                {
                    classProductlist.add(Product);
                }
            }
        }

        notifyDataSetChanged();
    }

}

谢谢

最佳答案

以下代码解决了我在ListViewAdapter中的问题

// Listen for ListView Item Click
        view.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            // Send single item click data to SingleItemView Class
            String mytitle=holder.listContent.getText().toString();

            if(mytitle.equals("murakoze")) {

                // Play song

                mp.reset();// stops any current playing song
                mp = MediaPlayer.create(mContext, R.raw.murakoze);// create's
// new
// mediaplayer

// with
   // song.
                mp.start(); // starting mediaplayer

            }
        }
    });
    return view;
   }
