Android listview search index from linked exception in fragment

Hi i am working with android. I am trying to implement a list search in my application. I have an edit text and get a value from that edit text and update my list with the base adapter. Now the problem is that it works perfect for 4 character searches. When I enter the 5th character it closes and shows the index from the associated exception. I searched a lot and was guessing the answer "remove getcount". But still it doesn't solve my problem. How can I solve this problem? Thanks in advance:)

 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));

 }
 }); 

      

        
        
        
      

    

here is my cat log

here is my adapter class
