一次仅选择一个复选框的自定义列表视图

我有一个自定义列表视图，每一行都包含一个复选框和文本。现在我想要的是，如果列表视图行的任何一个复选框被选中，那么其他行中的其他复选框如果被选中。它将被自动删除。（即一次只能选择一个复选框）。我应该怎么做。

到目前为止我所做的如下：

public class CustomAdapter extends BaseAdapter{

    Context context;
    List<String> items;

     boolean array[];


    public CustomAdapter(Context context, List<String> items) {
    super();
    this.context = context;
    this.items = items;
    array =new boolean[items.size()];
}


    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return items.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return items.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        View v=convertView;
        final int pos=position;
        if(v==null)
        {
            v=LayoutInflater.from(context).inflate(R.layout.list,null);
        }

        TextView txt1=(TextView) v.findViewById(R.id.textView1);
        final CheckBox chkbox=(CheckBox) v.findViewById(R.id.checkBox1);

        txt1.setText(items.get(position));
        int selectedindexitem=0;
        chkbox.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                if(chkbox.isChecked())
                {
                    array[pos]=true;


                }else{
                    array[pos]=false;
                }
            }
        }); 
        chkbox.setChecked(array[pos]);





        return v; 
    }




}

In this code i can select multiple checkbox at a time but i need only one checkbox should be checked one at a time.

您需要相应地跟踪所选项目和代码。

public class CustomAdapter extends BaseAdapter{
    Integer selected_position = -1;

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
            // Your Code

            chkbox.setChecked(position==selected_position);

            chkbox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    if(isChecked)
                    {
                        selected_position =  position;
                    }
                    else{
                         selected_position = -1;
                    }
                    notifyDataSetChanged();
                }
            });
            return convertView;


        }
}
