android中带有复选框错误的自定义列表视图

Question

嗨，我正在创建一个带有两个chekboxes的自定义listview，而problen是当我选中一个复选框并向下滚动到与选中的复选框相邻的另一个复选框时，我也想知道为什么会发生这种情况，我应该知道为什么会发生此错误，这是我的码

public class ListTestActivity extends ListActivity {
/** Called when the activity is first created. */

    presidents =getResources().getStringArray(R.array.pres_array);

                getModel());
        Log.d(tag," event");
        setListAdapter(adapter);
        Log.d(tag," 1");
    }

    private List<Model> getModel() {
        Log.d(tag,"bht");
        int index = presidents.length;

            list.add(get(Linux));
            Log.d(tag," 2");
                     //if(positio>=10){

mViewHolder.checkBox = (CheckBox)convertView.findViewById(R.id.checkBox1);
            mViewHolder.checkBox.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    CheckBox cb = (CheckBox) v.findViewById(R.id.checkBox1);
                    if (cb.isChecked()) {
                        checkBoxArrayList.set(position, true);
                    } else if (!cb.isChecked()) {
                        checkBoxArrayList.set(position, false);
                    }
                }
            });
