自定义光标适配器错位置 [英] custom cursor adapter wrong position

问题描述

我已经从数据库获取日期自定义光标适配器和填充列表，它的 onlistItemClick 监听我显示连接至该行的观点，然后再次单击将隐藏视图，

一切工作正常，但我有两个问题，结果
1） - 我有10行，它表明10，但是当我登录的位置，它给我的只有那些位置，适合屏幕结果。
2） - 当我在一排点击，观点似乎是连接到该行，但是当我向下滚动，我发现另一种观点是可见按住屏幕，

i have a custom cursor adapter that fetches date from database and populate list , and its onlistItemClick listener i show a view attached to that row, and then hide that view by clicking it again,
everything is working fine, but i have two problems,
1)- i have 10 rows, it shows 10, but when i log positions, it gives me only those positions, that fits to screen.
2)- when i click on a row, view appears that is attached to that row, but when i scroll down, i found another view is visible down the screen,

这是我的适配器，

    public class CustomCursorAdapter extends CursorAdapter {
    private LayoutInflater mInflater; 

    public CustomCursorAdapter(Context context, Cursor cursor, int flags) {
        super(context, cursor, flags);
        mInflater = LayoutInflater.from(context);
    }

    @Override
    public void bindView(View view, final Context context, final Cursor cursor) {
        TextView textView = (TextView) view.findViewById(R.id.txtview);
        textView.setText(cursor.getString(cursor.getColumnIndex("text")));
    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        //in that "list_layout.xml" i made a view that has to show and hide on click listener
        View rowView = mInflater.inflate(R.layout.list_layout, parent, false);
        if(cursor.getPosition()%2 != 0)
        {
            rowView.setBackgroundResource(R.drawable.list_selector);
        }
        return rowView;
    }
}

我从小时的工作要弄清楚这个问题，但不成功..结果
请帮助任何照顾接受者。

I am working from hours to figure out the issue, but in vain..
Please help any care taker.

推荐答案

试着写getView方法来代替。

Try writing getView method instead.

例如：

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null)
            convertView = mInflater
                    .inflate(R.layout.list_layout, parent, false);
        if (getCursor().getPosition() % 2 != 0) {
            convertView.setBackgroundResource(R.drawable.list_selector);
        }else{

            convertView.setBackgroundResource(<-Something->);
        }
        return convertView;

    }

修改

 @Override
    public void bindView(View view, final Context context, final Cursor cursor) {
        TextView textView = (TextView) view.findViewById(R.id.txtview);
        textView.setText(cursor.getString(cursor.getColumnIndex("text")));
        if(cursor.getPosition()%2 != 0)
        {
            view.setBackgroundResource(R.drawable.list_selector);
        }
    }
