我将创建一个动态视图。在这个视图中，我可以用5个CheckBox设计一个动态视图
我将尝试下面的动态视图代码：

private void chkdynamic() {
        final String name[] = {"Credit Card", "Debit Card","Bank Deposit","in-app Purchase", "PayPal"};
        /*int Array_Count=0;
        String[] Str_Array = new String[0];

        Array_Count = Str_Array.length;*/

        for (int i = 0; i < name.length; i++)
        {

            final View v = new View(this);
            v.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, 5));
            v.setBackgroundColor(getResources().getColor(R.color.border_gray));

            LinearLayout row = new LinearLayout(this);
            row.setOrientation(LinearLayout.VERTICAL);
            row.setId(i);
            row.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
            final CheckBox checkBox = new CheckBox(activity);
            checkBox.setId(i);
            checkBox.setText(name[i]);
            checkBox.setTextColor(getResources().getColor(R.color.gray_text));
            checkBox.setButtonDrawable(getResources().getDrawable(R.drawable.chk_btn));
            checkBox.setPadding(20,60,0,60);
            checkBox.setTextSize(20);
            LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                    LinearLayout.LayoutParams.WRAP_CONTENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT
            );
            params.setMargins(60, 0, 0, 0);
            checkBox.setLayoutParams(params);
            row.addView(checkBox);
            row.addView(v);
            ll_dynamic.addView(row);
        }
    }

按照上面的代码5复选框，根据名称长度创建。
我的问题是现在如何i setOnCheckedChangeListener为复选框
如果我选中CheckBox一个，然后其他CheckBox取消选中如何在动态视图中实现这一点。
请给我一个解决办法。

        row.addView(checkBox);

        row.addView(v);
        ll_dynamic.addView(row);
    }
}
