java.lang.IndexOutOfBoundsException while performing search functionality

[Nik2505]

Getting invalid section if I perform search on list. @Override public int getSectionItemCount(int section) { return size; } here section is getting more than sectioncount.

Please provide more info or example, how do you perform the search and who exactly throwing IndexOutOfBoundsException

I have performed search filtering as per list header text and list item text. using...

ArrayList<ArrayList> mDataset = new ArrayList<>();

@Override public void afterTextChanged(Editable s) { String text = search.getText().toString().toLowerCase(Locale.getDefault()); if (mDataset.size() > 0) adapter.filter(text); }

Filter method inside adapter class.

public void filter(String charText) {
    charText = charText.toLowerCase(Locale.getDefault());
    mDataset.clear();
    if (charText.length() == 0) {
        mDataset.addAll(mDataset_copy);
    } else {

        for (int i = 0; i < mDataset_copy.size(); i++) {
            ArrayList<CustomClass> categoriesList = new ArrayList<>();
            ArrayList<CustomClass> mList = mDataset_copy.get(i);
            for (CustomClass wp : mList) {
                if (wp.getHeaderDate().toLowerCase(Locale.getDefault()).contains(charText) || wp.getListTitle().toLowerCase(Locale.getDefault()).contains(charText)) {
                    categoriesList.add(wp);
                }
            }
            if (categoriesList.size() > 0) {
                mDataset.add(categoriesList);
            }
        }
    }
    notifyDataSetChanged();
}

@Override
public int getSectionCount() {
    return mDataset.size();
}

@Override
public int getSectionItemCount(int section) {
    return mDataset.get(section).size();
}

Getting wrong section count at getSectionItemCount. If my mDataset.size() is 1 and It have 3 items then section index becomes 0 and then 1.

You cannot use notifyDataSetChanged, use notifyAllSectionsDataSetChanged instead. Look at Usage list 5th line.
