ListView中的项目不保留其值

Question

我有一个带有自定义适配器的ListView，每个项目都有一个标题和一个描述按钮，弹出一个Dialog，每个项目都有一个唯一的描述。一切似乎都在工作，除了滚动一点点后，描述按钮拉出了错误的描述。根据我的理解，ListView中的幕后必须发生一些事情，导致它在滚动后没有将正确的值绑定到项目。我怀疑问题可能是我在Activity类的ListView上设置OnItemClickListener，以及每个Button的行为。以下代码来自包含ListView的Activity。

lv.setAdapter(adapter);

    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, final int position, long id) {
            //CheckBox checkBox = (CheckBox) view.findViewById(R.id.checkbox);
            //checkBox.setChecked(!checkBox.isChecked());
            final View tempView = view;
            LinearLayout countLayout = (LinearLayout) view.findViewById(R.id.counter_layout);
            TextView count = (TextView) countLayout.findViewById(R.id.counter);
            ImageView add = (ImageView) countLayout.findViewById(R.id.add_sign);
            ImageView minus = (ImageView) countLayout.findViewById(R.id.minus_sign);
            ImageView description = (ImageView) view.findViewById(R.id.info_button);
            minus.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    list.get(position).setCount(list.get(position).getCount() - 1);
                    LinearLayout countLayout = (LinearLayout) tempView.findViewById(R.id.counter_layout);
                    TextView count = (TextView) countLayout.findViewById(R.id.counter);
                    count.setText("" + list.get(position).getCount());
                    try {

                        adapter.notifyDataSetChanged();
                        writeObject(getApplicationContext(), "checklist", new Lists(list, customList));
                    } catch (Exception e) {
                        e.printStackTrace();
                        Toast toast = Toast.makeText(getApplicationContext(), "Change not saved", Toast.LENGTH_SHORT);
                        toast.show();
                    }
                }
            });
            add.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    list.get(position).setCount(list.get(position).getCount() + 1);
                    LinearLayout countLayout = (LinearLayout) tempView.findViewById(R.id.counter_layout);
                    TextView count = (TextView) countLayout.findViewById(R.id.counter);
                    count.setText("" + list.get(position).getCount());
                    try {
                        adapter.notifyDataSetChanged();
                        writeObject(getApplicationContext(), "checklist", new Lists(list, customList));
                    } catch (Exception e) {
                        e.printStackTrace();
                        Toast toast = Toast.makeText(getApplicationContext(), "Change not saved", Toast.LENGTH_SHORT);
                        toast.show();
                    }
                }
            });
            description.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    AlertDialog alert = new AlertDialog.Builder(ChecklistActivity.this)
                            .setTitle("Description")
                            .setMessage(list.get(position).getDescription())
                            .setPositiveButton("Okay", new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog, int which) {
                                    //Do Nothing
                                }
                            })
                            .create();
                    alert.setCanceledOnTouchOutside(true);
                    alert.show();
                }
            });


        }

    });
