  8. Hi all.

    I was not able to answer your comments. Sorry all..

    Ken - use indexOf() method.

    change this function..

    public void onTextChanged(CharSequence s, int start,
    int before, int count)
    {

    textlength = edittext.getText().length();
    text_sort.clear();
    image_sort.clear();

    for (int i = 0; i < text.length; i++)
    {
    if (textlength <= text[i].length())
    {
    if (text[i].indexOf(edittext.getText().toString()) != -1)
    {
    text_sort.add(text[i]);
    image_sort.add(image[i]);
    }
    }
    }

    1. How can I search a word without the case sensitive? I tried in this way but under .indexOf appears a red line.

      if (text[i].indexOf(edittext.getText().toString()equalsIgnoreCase((String) text[i].subSequence(0, textlength)) != -1)

  9. Carontes --

    if you have two string arrays and you need to search any one string array then

    use this code

    if (edittext.getText().toString().
    equalsIgnoreCase((String) text1[i].subSequence(0, textlength)) || edittext.getText().toString().
    equalsIgnoreCase((String) text2[i].subSequence(0, textlength)) )

    1. Thank you for your answer. When I try to type the first letter into the search box the app crash. The logcat gives me the NullPointerException at these lines:

      listview.setAdapter(new MyCustomAdapter(text_sort,image_sort));

      data_text[i] = text.get(i);


      All I did with your code was only to change int[] with String[] and EditText with AutoCompleteTextView. How can I solve this problem? Thank you.

      Delete
    2. Sorry, I resolved my problem. I made a mistake with my code. Thank you again for your advice.

      Delete
    3. Sorry to bother you again but the app crash when I delete the first letter from the search box. For example if I wrote "Man" when I try to delete "M" the app crash and the logcat gives me
      java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0

      at this line:
      image_sort.add(image[i]);

      I tried with your original code without add the advice you gave me.

    ReplyDelete
  12. Hi Carontes, to search within a String and without case sensitive..
    replace your:

    if (text[i].indexOf(edittext.getText().toString()equalsIgnoreCase((String) text[i].subSequence(0, textlength)) != -1)

    with:

    if(text[i].toLowerCase().indexOf(edittext.getText().toString().toLowerCase()) != -1)

  13. how to get the list is clicked and go to the next class?

    ReplyDelete
  14. Hi ownlatte,

    Use INTENT.

    Intent i = new Intent(YourCurrentClass.this, NextClass.class);
    startActivity(i);

    ReplyDelete
  15. and how about when using a condition such as if-else, I use this there is nothing wrong but I can't go to the next class.

    listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView arg0, View v, int arg2, long arg3) {

    String item = ((TextView)edittext).getText().toString();
    select(item);

    }

    private void select(String item) {

    try {
    Intent i = null;
    if (item.equals("sunday")) {
    startActivity(new Intent(ListviewActivity.this, sunday.class));
    }else if (item.equals("monday")) {
    startActivity(new Intent(ListviewActivity.this, monday.class));
    }
    startActivity(i);
    } catch (Exception e) {
    e.printStackTrace();
    }

  18. Hi,

    I have three columns viz company code,fname,lname...i want to search the list on all the three..like the user is free to enter anything in the search box and it will fetch all the particular records...

    Please tell me how to implement the same.

    I tried doing it using elseif loop but the application crashes as the company code has a fixed length of 4 but fname and lname varies..

    Please can anyone help me with this.
