我有一個標籤片段中的列表視圖， 現在列表視圖中我有兩種觀點一種觀點認爲是已經在走了visibility.when我滾動列表視圖兩種視圖disappears.I正與持有人的處理，但我仍然面臨這個問題。爲什麼當我滾動時，列表視圖項目中的圖像視圖消失？
這裏是我的xml：

這裏是我的適配器：

}
if (yettop) {

} else {
Constants.arr_global.add(map);
}
}else {
Constants.arr_global.add(map);
}
}
}
}
});
return convertView;
}
的問題是：
if (model.getInStock().matches("In Stock")) {
holder.ll_unavail.setVisibility(View.GONE);
}else {
holder.ll_unavail.setVisibility(View.VISIBLE);
holder.ll_add.setVisibility(View.GONE);
}
