列表视图不总是刷新 + 屏幕错误
Listview not refresh always + screen errors
你好，我有一个问题 Listview。
我使用列表视图显示列表中的项目。
创建 activity 一切正常。
...
如果我在项目上长按显示对话框，我可以在其中编辑名称项目，如果确认编辑我在 activity 中使用 listview 的 s 静态变量。 (true) 这个布尔变量在加载的 Timer 上。从 设置变量将读取项目。
我用
阅读了项目
ListAdapter.clear();
thadapter.clear();
for (int i=1;i<prvy.getPacageItem2(indexpacage)+1;i++) {
ListAdapter.add(String.valueOf(prvy.citajItem(indexpacage,i)));
Toast.makeText(this, "obnovujem" + " "+ prvy.citajItem(indexpacage,i), Toast.LENGTH_SHORT).show();
}
thadapter = new MyThumbnailAdapter(getApplication(), R.layout.list_row, ListAdapter);
List.setAdapter(thadapter);
一切运行。但是，如果编辑项目 3-5 次此代码 ↑ 将所有行添加到 thadapter 并将其放在列表（列表视图）上，但列表视图无法在显示时重写列表视图。我在这个代码中有 TOAST，程序读起来很好。
每个都在这里坠毁
thadapter = new MyThumbnailAdapter(getApplication(), R.layout.list_row, ListAdapter);
List.setAdapter(thadapter);
但我不明白为什么所有 运行 有时都很好，然后下一个有一些错误，而下一个 运行 也很好（有时）
如果 运行 不适合第一行的项目，那么 prgram 运行 有时也适合其他行。
它不是重复的随机...
请问您有什么想法吗？
谢谢。
此代码调用读取信息并将信息放入列表视图的代码。

这里有一些来自 class 的方法，我在其中保存了所有变量（我在这个问题上需要这些变量）。

Wrong view
有时，如果我编辑行，Toas 会读取正确的字符串，但 Listview 不会重写。
无论何时更改 ListView 使用的数据，都必须在列表的适配器上调用 notifyDataSetChanged()。也许这会解决问题。
我需要在对话框中使用重写 Listview 的方法进行同步确认编辑。
或从
切换顺序
AddItemInPacage.obnovitem = true;
AddItemInPacage.prvy = prvy;
至
AddItemInPacage.prvy = prvy;
AddItemInPacage.obnovitem = true;
因为如果 AddItemInPacage.obnovitem=true; 首先 Activity 使用变量 prvy 中的旧信息。当对话中的变量 prvy 已满时。列表视图使用此变量中的旧信息完成工作。

屏幕 Wrong view
有时，如果我编辑行，Toas 会读取正确的字符串，但 Listview 不会重写。
无论何时更改 ListView 使用的数据，都必须在列表的适配器上调用 notifyDataSetChanged()。也许这会解决问题。
我需要在对话框中使用重写 Listview 的方法进行同步确认编辑。
或从
切换顺序AddItemInPacage.obnovitem = true;
AddItemInPacage.prvy = prvy;
至
AddItemInPacage.prvy = prvy;
AddItemInPacage.obnovitem = true;
因为如果 AddItemInPacage.obnovitem=true; 首先 Activity 使用变量 prvy 中的旧信息。当对话中的变量 prvy 已满时。列表视图使用此变量中的旧信息完成工作。
