您好我正在使用android。我试图在我的应用程序中实现列表视图搜索。我有一个编辑文本并从该编辑文本中获取值并更新我的列表视图使用基础适配器。现在的问题是，它可以完美地搜索4个字符。当我输入第5个字符时，强制关闭并显示索引超出限制的异常。我搜索了很多，然后回答“删除getcount”方法。但它仍然不能解决我的问题。我该如何解决这个问题？感谢提前:)Android的listview搜索原因索引出界异常在片段
search.addTextChangedListener(new TextWatcher()
{
public void afterTextChanged(Editable s)
{
}
public void beforeTextChanged(CharSequence s, int start,
int count, int after)
{
}
public void onTextChanged(CharSequence s, int start,
int before, int count)
{
textlength = search.getText().length();
date1.clear();
desc1.clear();
time1.clear();
place1.clear();
for (int i = 0; i < date.length; i++)
{
String a=search.getText().toString();
if (a.equalsIgnoreCase((String) date[i].subSequence(0, textlength)) ||
a.equalsIgnoreCase((String) descriptions[i].subSequence(0, textlength))||
a.equalsIgnoreCase((String) time[i].subSequence(0, textlength)) ||
a.equalsIgnoreCase((String) place[i].subSequence(0, textlength)))
{
date1.add(date[i]);
desc1.add(descriptions[i]);
time1.add(time[i]);
place1.add(place[i]);
}
}
listView.setAdapter(new dataListAdapter(date1,desc1,place1,time1));
}
});

这里是我的适配器类
class dataListAdapter extends BaseAdapter {
String[] Date, Desc,Loc, Time;
dataListAdapter() {
Date = null;
Desc = null;
Loc = null;
Time = null;
}
public dataListAdapter(String[] text, String[] text1,String[] text3,String[] text4) {
Date = text;
Desc = text1;
Loc = text3;
Time = text4;
}
public dataListAdapter(ArrayList<String> text, ArrayList<String> text1,ArrayList<String> text2, ArrayList<String> text3) {
Date = new String[text.size()];
Desc = new String[text1.size()];
Loc = new String[text2.size()];
Time = new String[text3.size()];
for(int i=0;i<text.size();i++)
{
Date[i] = text.get(i);
Desc[i] = text1.get(i);
Loc[i] = text2.get(i);
Time[i] = text3.get(i);
}
}
public int getCount() {
return Date.length;
}
public Object getItem(int arg0) {
return null;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = getActivity().getLayoutInflater();
View row;
row = inflater.inflate(R.layout.event_item, parent, false);
TextView date, desc,loc,time;
date = (TextView) row.findViewById(R.id.date);
desc = (TextView) row.findViewById(R.id.desc);
loc = (TextView) row.findViewById(R.id.place);
time = (TextView) row.findViewById(R.id.time);
Typeface font = Typeface.createFromAsset(
getActivity().getAssets(),
"Ace.ttf");
date .setTypeface(font);
date.setText(Date[position]);
desc.setText(Desc[position]);
loc.setText(Loc[position]);
time.setText(Time[position]);
return (row);
}
}
