你好，我有一个问题是Listview。
我将列表视图用于列表中的显示项目。
创造活动就是一切都好。 ... 如果我在项目上显示长按对话框，我可以编辑名称项目，如果确认编辑我在listview中切换活动中的静态变量。 （true）这个布尔变量在Timer上加载。并且从巫婆设置变量将读取项目。
我用
阅读了这些项目 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);
一切都在运行。但如果编辑项目3-5次这个代码↑将所有行添加到thadapter并将其放在List（Listview）上但Listview不能重写listview显示。我有这个代码和程序读取良好的TOAST。 每个人都在这里坠毁
thadapter = new MyThumbnailAdapter(getApplication(), R.layout.list_row, ListAdapter);
List.setAdapter(thadapter);
但是我不知道为什么所有人都运行良好一段时间，接下来有一些错误，然后运行良好（有些时候） 并且如果第一行中的项目运行不正常，prgram也会对其他行运行一段时间。
它不是重复的随机......
请你有一些想法吗？
感谢。
此代码调用代码，用于在listview上读取和放置信息..
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);
____________________________________________对焦虑的反应
这里我设置静态变量Boolean是在timer和AddItemInPacage.prvy = prvy;是类我在哪里保存信息我尝试放在listview
Statis因为我是从弹出窗口（对话框）
设置的AddItemInPacage.obnovitem=true;
AddItemInPacage.prvy=prvy;
以下是我保存所有变量的类的一些方法（我需要解决这个问题）。
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;
}

屏幕 Wrong view
有时如果我编辑行Toas读取好的字符串，但Listview没有重写。
答案 0 :(得分：0)
每当您更改ListView使用的数据时，您必须在列表的适配器上调用Memory.h:
#include <pthread.h>
class Memory {
static pthread_mutex_t mutex_;
}
Memory.cpp:
#include <Memory.h>
#include <pthread.h>
Memory::Memory() :
#ifdef __APPLE__
pthread_mutex_init(&mutex_, NULL);
#endif
。也许这会解决问题。
答案 1 :(得分：0)
我需要在Dialog中使用重写Listview的方法进行同步确认编辑。
或从
切换序列
AddItemInPacage.obnovitem = true;
AddItemInPacage.prvy = prvy;
到
AddItemInPacage.prvy = prvy;
AddItemInPacage.obnovitem = true;
因为如果AddItemInPacage.obnovitem=true;第一个Activity使用变量prvy中的旧信息。当变量prvy从对话框中填满时。 Listview使用此变量中的旧信息完成工作。
