单击索引布局仅在列表滚动期间有效

Question

我创建了一个右侧有索引的列表，感谢IndexableListView个文件。这是我的活动：

public class FindByname extends Activity {
    private Database db = new Database(this);
    private IndexableListView mListView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.indexable);

        SQLiteDatabase dbR = db.getReadableDatabase();
        ArrayList<User> list = new ArrayList<User>();
        list = createFullList(dbR);

        ContentAdapter adapter = new ContentAdapter(this, R.layout.user_list_row, list);

        mListView = (IndexableListView) findViewById(R.id.listview);
        mListView.setAdapter(adapter);
        mListView.setFastScrollEnabled(true);
    }

    private ArrayList<User> createFullList(SQLiteDatabase rw) {
        ArrayList<User> list = new ArrayList<User>();

        Cursor result = rw.rawQuery("SELECT _id, title, phone, city, category FROM users ORDER BY title ASC", null);
        while (result.moveToNext()) {
            list.add(new User(result.getString(0), result.getString(1), result.getString(2), result.getString(3), result.getString(4)));
        }
        result.close();
        return list;
    }

    private class ContentAdapter extends MyAdapter implements SectionIndexer {

        private String mSections = "#ABCDEFGHIJKLMNOPQRSTUVWXYZ";

        public ContentAdapter(Context context, int textViewResourceId, List<User> objects) {
            super(context, textViewResourceId, objects);
        }

        @Override
        public int getPositionForSection(int section) {
            // If there is no item for current section, previous section will be selected
            for (int i = section; i >= 0; i--) {
                for (int j = 0; j < getCount(); j++) {
                    if (i == 0) {
                        // For numeric section
                        for (int k = 0; k <= 9; k++) {
                            if (StringMatcher.match(String.valueOf(getItem(j).getNome_user().charAt(0)), String.valueOf(k)))
                                return j;
                        }
                    } else {
                        if (StringMatcher.match(String.valueOf(getItem(j).getNome_user().charAt(0)), String.valueOf(mSections.charAt(i))))
                            return j;
                    }
                }
            }
            return 0;
        }

        @Override
        public int getSectionForPosition(int position) {
            return 0;
        }

        @Override
        public Object[] getSections() {
            String[] sections = new String[mSections.length()];
            for (int i = 0; i < mSections.length(); i++)
                sections[i] = String.valueOf(mSections.charAt(i));
            return sections;
        }
    }
}

我得到这样的东西：

问题是，由于我的项目是可点击的，因此点击索引不起作用。索引上的字母只能在列表滚动期间单击！如果我在单击字母时停止滚动（在索引消失之前），它会触发列表项的单击，而不是单击索引字母。

以下是处理列表项上的点击侦听器的MyAdapter类：

public class MyAdapter extends ArrayAdapter<User> {
    private Context context;
    private int layoutid;
    private List<User> data;

    public MyAdapter(Context context, int textViewResourceId, List<User> objects) {
        super(context, textViewResourceId, objects);
        this.context = context;
        this.layoutid = textViewResourceId;
        data = objects;
    }

    public int getCount() {
        return data.size();
    }

    @Override
    public User getItem(int position) {
        return data.get(position);
    }

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

    public View getView(final int position, View convertView, ViewGroup parent) {
        View row = convertView;
        UserHolder holder = null;
        if (row == null) {
            LayoutInflater inflater = ((Activity)context).getLayoutInflater();
            row = inflater.inflate(layoutid, parent, false);

            holder = new UserHolder();
            holder.name = (TextView) row.findViewById(R.id.nameUser);
            holder.city = (TextView) row.findViewById(R.id.cityUser);
            holder.rating = (RatingBar) row.findViewById(R.id.ratingUser);
            holder.distance = (TextView) row.findViewById(id.distanceKm);
            holder.category = (TextView) row.findViewById(R.id.catUser);
            row.setTag(holder);
        } else {
            holder = (UserHolder)row.getTag();
        }

        User user = data.get(position);
        holder.name.setText(user.getNome_user());
        holder.city.setText(user.getComune());
        holder.rating.setRating(user.getVoto());
        holder.distance.setText(user.getDistanza());
        holder.category.setText(user.getCategory());

        LayerDrawable stars = (LayerDrawable) holder.rating.getProgressDrawable();
        stars.getDrawable(2).setColorFilter(Color.rgb(255, 215, 0), android.graphics.PorterDuff.Mode.SRC_ATOP);

        row.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                User merc = getItem(position);
                Intent intent = new Intent(context, ViewUser.class);
                intent.putExtra("id", merc.getId());
                context.startActivity(intent);
            }
        });
        return row;
    }

    static class UserHolder {
        TextView name;
        TextView city;
        RatingBar rating;
        TextView distance;
        TextView category;
    }
}

可能是什么问题？

抱歉我的英文

这适用于github的IndexableListViewActivity。

  mListView.setOnItemClickListener(new OnItemClickListener(){
        public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3)
        {
            Toast.makeText(IndexableListViewActivity.this,
               "position: " + position + "\n\n" + mItems.get(position), Toast.LENGTH_SHORT).show();
        }});

对于您的FindByName活动，它更像是：

  mListView.setOnItemClickListener(new OnItemClickListener(){
        public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3)
        {
         User user = list.get(position);

         Toast.makeText(FindByName.this, 
             "position: " + position + "\n\n" + user.getNome_user(), Toast.LENGTH_SHORT).show();
        }});
