你好，我有一个问题，巫婆Listview
我使用listview来显示列表中的项目。
On create activity is everything okay。…如果我长触摸项目显示的对话框，我可以编辑名称项目，如果确认编辑我切换静态变量与listview活动。(true)这个布尔变量是在计时器上加载的。并设置变量从女巫将读取项目。
我读取带有
的条目 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倍这些代码↑添加所有行到适配器，并把它放在列表(Listview)，但Listview不能重写Listview显示。我有TOAST在这些代码和程序阅读良好。每一个崩溃在这里
thadapter = new MyThumbnailAdapter(getApplication(), R.layout.list_row, ListAdapter);
List.setAdapter(thadapter);
但我不知道为什么所有运行良好的一些时间和下一个有一些错误和下一个运行良好的太(某些时候)如果对第一行的项目运行不正常，程序有时也会对其他行运行良好。
它不是重复的，它是随机的…
你有什么想法吗?谢谢。
这个代码调用的代码读取并把信息放在listview..
Timer timer = new Timer();
//TODO timer
timer.schedule(
new TimerTask() {
@Override
public void run() {
runOnUiThread(
new Runnable() {
@Override
public void run() {
if (obnovitem) {
ObnovItem();
obnovitem= false;
}
}
}
);
}
}, 0, 150);
sorry for English:/
____________________________________________ 反应的言论
这里我设置静态变量布尔是在定时器和additeminpackage .prvy=prvy;是保存信息的类，我试着放在listview
stats，因为我是从弹出(对话框)
设置的AddItemInPacage.obnovitem=true;
AddItemInPacage.prvy=prvy;
这里有一些方法从类，我保存了所有的变量(我需要在这个问题上)。
String[][][] packinglist = new String[6][100][2];
public String citajItem(int pacage, int item) {
return packinglist[pacage][item][0];
}
public void pridajItem(String nazovbalika,int pacagenum) {
pocItem++;
setPacageItem2(getPacageItem2(pacagenum)+1,pacagenum);
packinglist[pacagenum][packageitem++][0]= nazovbalika;
}

错误的观点
有时如果我编辑行Toas读好的字符串，但Listview没有重写。
当你改变ListView使用的数据时，你必须调用列表适配器上的notifyDataSetChanged()。
我需要一个同步的确认编辑对话框的方法重写Listview。
或从
切换顺序AddItemInPacage.obnovitem = true;
AddItemInPacage.prvy = prvy;
AddItemInPacage.prvy = prvy;
AddItemInPacage.obnovitem = true;
因为如果AddItemInPacage.obnovitem=true;优先活动在变量prvy中处理旧信息。当变量从对话框中被填满时。Listview在此变量中完成旧信息的处理。
