ImageView在列表视图中单击

Question

我有一个类似的代码，它可以工作，但是没有响应，有时我们需要在imageview上单击两次或三下以显示对话框。请您帮我吗？

    Cursor cursor = dbHelper.fetchAllArticle();

    // The desired columns to be bound
    String[] columns = new String[] {
            DataBaseAdapter.KEY_CODE,
            DataBaseAdapter.KEY_DESIGANTION,
            DataBaseAdapter.KEY_UNITE,
            DataBaseAdapter.KEY_COLISAGE,
            DataBaseAdapter.KEY_APPLICATION
    };

    // the XML defined views which the data will be bound to
    int[] to = new int[] {
            R.id.xcode,
            R.id.xdesignation,
            R.id.xunite,
            R.id.xcolisage,
            R.id.xapplication,
    };

    // create the adapter using the cursor pointing to the desired data
    //as well as the layout information
    dataAdapter = new SimpleCursorAdapter(
            this, R.layout.articleinfo,
            cursor,
            columns,
            to,
            0);



    ListView listView = (ListView) findViewById(R.id.listView1);

    // Assign adapter to ListView
    listView.setAdapter(dataAdapter);   

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long viewId) {
                    ImageView ivm= (ImageView) view.findViewById(R.id.imga);
                    final Cursor cursorab = (Cursor) parent.getItemAtPosition(position);
                    ivm.setOnClickListener(new OnClickListener() {
                        @Override
                        public void onClick(View view) {
                           LayoutInflater li = LayoutInflater.from(MainActivity.this);
                           View dialogView = li.inflate(R.layout.ajoutpanier, null);
                            final AlertDialog.Builder alertDialog2 = new AlertDialog.Builder(
                                    MainActivity.this);
                            alertDialog2.setView(dialogView);
                            alertDialog2.setTitle("Information");
                            alertDialog2.setIcon(R.drawable.achat);
                            alertDialog2.setPositiveButton("ok",
                                    new DialogInterface.OnClickListener() {
                                        public void onClick(DialogInterface dialog, int which) {
                                        }
                                    });
                            alertDialog2.setNegativeButton("Annuler",
                                    new DialogInterface.OnClickListener() {
                                        public void onClick(DialogInterface dialog, int which) {
                                            dialog.cancel();
                                        }
                                    });
                            alertDialog2.show();
                        }
                    });
                }
            });
