對不起，因爲標題不好。列表視圖更新視圖哪些未觸及
我在運行時添加一個切換按鈕到列表視圖。 當我點擊按鈕時，它的狀態發生了變化。但問題是，當我向下滾動其他項目也得到選擇。
例如，如果點擊第一個切換按鈕，第六個切換按鈕也會被檢查。
這是一個非常奇怪的行爲。
下面是acitivty

這裏的XML代碼是因爲我在適配器

這裏充氣視圖中的XML代碼爲getView

params.setMargins(0, 0, getPx(35), 0);
selector.setLayoutParams(params);
selector.setTextOff("");
selector.setText("");
selector.setTextOn("");
selector.setOnCheckedChangeListener(this);
selector.setTag(String.valueOf(i));

RelativeLayout card = (RelativeLayout) convertView.findViewById(R.id.card_view);
