复选框重复检查列表视图中 [英] Checkbox check repeats in listview

问题描述

我有以下实现自定义的ListView使用的CursorAdapter填充：

I have the following implementation of a custom ListView populated using a CursorAdapter:

private class CurAdapter extends CursorAdapter{

        public CurAdapter(Context context, Cursor c, int flags) {

            super(context, c, flags);

        }

        @Override
        public void bindView(View view, Context context, Cursor cursor) {

            final ViewHolder holder = (ViewHolder) view.getTag();

            String name = (cursor.getString(cursor.getColumnIndexOrThrow("NotificationDateFor")));
            String image = cursor.getString(cursor.getColumnIndexOrThrow("imageUri"));



            holder.nametext.setText(name);
            setImage(image, holder.iv); 
            holder.chk.setOnClickListener(onchk);


        } 
        @Override
        public View newView(Context context, Cursor cursor, ViewGroup parent) {

            View view = LayoutInflater.from(context).inflate(R.layout.group_list, null);

            ViewHolder holder = new ViewHolder(view);
            view.setTag(holder);
            return view;

        }

        private View.OnClickListener onchk = new View.OnClickListener() {

            @Override
            public void onClick(View v) {


            }
        };


        public class ViewHolder {
            TextView nametext;
            RoundedImageView iv; 
            CheckBox chk; 

            public ViewHolder(View view){

                iv = (RoundedImageView)view.findViewById(R.id.imageView2);
                nametext = (TextView) view.findViewById(R.id.textView1);
                chk = (CheckBox) view.findViewById(R.id.checkBox1);

            }



        }

    }

我使用的是持有人的模式，以避免重复，但我得到检查盒随机检查时滚动我的名单，我该怎么会错过吗？

I am using a Holder pattern to avoid repetition, but I get check-boxes checked at random while scrolling my list, what do I miss here?

另外我想知道如何点击复选框的值存储在我的复选框的onClick。

Also I want to know how to store the values of clicked checkboxes in my onClick of the checkbox.

推荐答案

您创建一个像

List<Integer> positionList

和适配器getviewMethod

and adapter getviewMethod

checbox.setCheckedChanged method in 
positionList.add(position);

和

for(Integer int:positionList){
if(int==position){
yourCheckBox.setChecked(true);

}
}

} }
