Hello I have a problem witch Listview.
I use listview for show items in list.
On create activity is everything okay. ... If I longtouch on item showed dialog where I can edit name item, If confirm editing I switch static variable in activity with listview. (true)This Boolean variable is on Timer which load. And set variable from witch will read items.
I read items with
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);
Everything run. BUT if edit item for 3-5 times thise code ↑ add all rows to thadapter and put it on List (Listview) but Listview can't rewrite listview on display. I have TOAST in thise code and program read good. Every crashed here
thadapter = new MyThumbnailAdapter(getApplication(), R.layout.list_row, ListAdapter);
List.setAdapter(thadapter);
But I don't have idea why all run good for some times and next have some error and next run good too (for some times) And If isn't run good for item in first row, prgram run good for other rows for some times too.
It isn't repeatly its random...
Please Do you have some ideas?
Thanks.
This code call code which read and put info on 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 :/
____________________________________________reaction for coments
Here I set static variable Boolean is in timer and AddItemInPacage.prvy=prvy; is class wehere are saved info who I try put on listview
Statis because I set it from popup (dialog)
AddItemInPacage.obnovitem=true;
AddItemInPacage.prvy=prvy;
Here are some method from class where I saved all variables (which i need on thise problem).
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;
}

Screen Wrong view
Sometimes if I edit row Toas read good string, but Listview no rewrite.
I needed a synchronized confirm edit in Dialog with a method which rewrote Listview.
Or switch sequence from
AddItemInPacage.obnovitem = true;
AddItemInPacage.prvy = prvy;
to
AddItemInPacage.prvy = prvy;
AddItemInPacage.obnovitem = true;
Because If AddItemInPacage.obnovitem=true; first Activity works with old information in variable prvy. And when variable prvy is full from dialog. Listview finish work with old information in this variable.
