我有一个ListView，我想用 SectionIndexer 实现 fastscroll，ImageView每行项目有 3 个项目，如下所示：

我想为每个图像视图 1、2、3 实现 onclicklistener 但是当我使用

imageview1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO here
            }
        });

它不起作用 -onClickListener没有被抓住，我不知道为什么。

这是我的适配器代码：

public class LazyImageLoadAdapter extends BaseAdapter implements SectionIndexer{

    private Context _context;
    private TopActivity _parentActivity;
    private static LayoutInflater inflater=null;
    public CoverBookLoader _coverBookLoader; 

    private ArrayList<RowBook> _arrListRowBooks;
    private int sizeView;

    public LazyImageLoadAdapter(Context context, ArrayList<RowBook> arrListRowBooks) {
        this._context = context;
        this._parentActivity = (TopActivity) context;
        this.sizeView = _parentActivity.getScreenWidth();
        this._arrListRowBooks = arrListRowBooks;
        inflater = (LayoutInflater) _context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        _coverBookLoader = new CoverBookLoader(_context);
    }

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

    public Object getItem(int position) {
        return position;
    }

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

    public static class ViewHolder{
        public LinearLayout llBook1;
        public ImageView ivBookCover1;
        public ProgressBar pbLoadingBookCover1;

        public LinearLayout llBook2;
        public ImageView ivBookCover2;
        public ProgressBar pbLoadingBookCover2;

        public LinearLayout llBook3;
        public ImageView ivBookCover3;
        public ProgressBar pbLoadingBookCover3;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {

        View vi=convertView;
        ViewHolder holderBook;

        LayoutParams lpSizeBook = new LayoutParams(sizeView / 3, sizeView * 3 / 5);

        if(convertView==null){
            vi = inflater.inflate(R.layout.listview_row, parent, false);

            holderBook = new ViewHolder();
            holderBook.llBook1 = (LinearLayout) vi.findViewById(R.id.llBook1);
            holderBook.llBook1.setLayoutParams(lpSizeBook);
            holderBook.ivBookCover1 = (ImageView) vi.findViewById(R.id.ivBookCover1);
            holderBook.pbLoadingBookCover1 = (ProgressBar) vi.findViewById(R.id.pbLoadingCoverImageBook1);

            holderBook.llBook2 = (LinearLayout) vi.findViewById(R.id.llBook2);
            holderBook.llBook2.setLayoutParams(lpSizeBook);
            holderBook.ivBookCover2 = (ImageView) vi.findViewById(R.id.ivBookCover2);
            holderBook.pbLoadingBookCover2 = (ProgressBar) vi.findViewById(R.id.pbLoadingCoverImageBook2);

            holderBook.llBook3 = (LinearLayout) vi.findViewById(R.id.llBook3);
            holderBook.llBook3.setLayoutParams(lpSizeBook);
            holderBook.ivBookCover3 = (ImageView) vi.findViewById(R.id.ivBookCover3);
            holderBook.pbLoadingBookCover3 = (ProgressBar) vi.findViewById(R.id.pbLoadingCoverImageBook3);

            vi.setTag( holderBook );
        } 
        else {
            holderBook=(ViewHolder)vi.getTag();
        }

        LinearLayout llBook1 = holderBook.llBook1;
        llBook1.setLayoutParams(lpSizeBook);
        ImageView ivBookCover1 = holderBook.ivBookCover1;
        ProgressBar pbLoadingBookCover1 = holderBook.pbLoadingBookCover1;

        LinearLayout llBook2 = holderBook.llBook2;
        llBook2.setLayoutParams(lpSizeBook);
        ImageView ivBookCover2 = holderBook.ivBookCover2;
        ProgressBar pbLoadingBookCover2 = holderBook.pbLoadingBookCover2;

        LinearLayout llBook3 = holderBook.llBook3;
        llBook3.setLayoutParams(lpSizeBook);
        ImageView ivBookCover3 = holderBook.ivBookCover3;
        ProgressBar pbLoadingBookCover3 = holderBook.pbLoadingBookCover3;

        RowBook rowBook = _arrListRowBooks.get(position);
        if (rowBook.getSize() < 3) {
            llBook3.setVisibility(View.VISIBLE);
        }
        if (rowBook.getSize() < 2) {
            llBook2.setVisibility(View.VISIBLE);
        }
        if (rowBook != null) {
            for (int i = 0; i < rowBook.getSize(); i++) {
                switch (i) {
                    case 0:
                        addBook(rowBook.getBookAt(i), ivBookCover1, pbLoadingBookCover1);                   
                        break;
                    case 1:

                        break;
                }
            }
        }
        return vi;
    }

    private void addBook(Books book , ImageView ivBookCover, ProgressBar pbLoadingCoverImageBook){

正如我上面的评论回复，我的适配器没有错，我的错在我的自定义列表视图中：

public class IndexableListView extends ListView {
// TODO
    @Override
    /**
     * intercept touch event - **WRONG HERE**
     */
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return true;
    }
// TODO
}

当我删除 onInterceptTouchEvent 时，我的问题就解决了
