我有一個列表視圖，其中包含16個項目。當我點擊項目1時，我改變了項目1的圖像。但是當我點擊項目2時，項目1的圖像不會改變。當項目2被點擊時，我想讓項目1的圖像回到默認狀態。並休息same.I搜索了很多在這個網上，但我沒有找到解決辦法。任何人都幫助我？在列表視圖上單擊此項時更改圖片
這裏我的代碼：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
menuitemfix = getResources().getStringArray(R.array.ns_menu_items_fix);
viewslide = new View(getActivity());
textslide = new TextView(getActivity());
imageslide = new ImageView(getActivity());
items.add(new HeaderSection("ĐĂNG NHẬP"));
items.add(new EntryItem("Thông báo", R.drawable.ic_slidemenu_notice));
items.add(new EntryItem("Nhắc lịch", R.drawable.ic_slidemenu_prompted));
items.add(new SectionItem("TRUYỀN HÌNH"));
items.add(new EntryItem("Kênh ", R.drawable.ic_slidemenu_live));
items.add(new EntryItem("Lịch phát sóng", R.drawable.ic_slidemenu_epg));

items.add(new EntryItem("Đăng xuất", R.drawable.ic_slidemenu_logout));
adapter = new EntryAdapter(getActivity(), items);
setListAdapter(adapter);

{
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.content_frame, fragment, tag);
if(addToBackStack) ft.addToBackStack(null);

}
我switch語句之前編輯我在onlistitemclick代碼：
if(temp_position != 0){
// Get icon from array in array.xml which contains name of image in drawable
int id_icon = getResources().getIdentifier(menuItemsIcon[temp_position],
"drawable", getActivity().getPackageName());
iv.setImageResource(id_icon);
}
但它不工作
保持上次改變圖像和視圖（它們保存在一個臨時變量）的軌道，當你點擊其他下一個項目復位，第二項也是這樣做 – Pragnani
是的。我知道算法，但我無法準確編寫代碼。你可以編寫代碼來幫助我！ – Tungken
