Add a search filter on RecyclerView with Cards?

Question

I found solutions for filters on ListView and SearchView on RecyclerView separately, but I wish to combine them. Is it even possible?<

Answer 1

Inside Fragment Class declare that:

protected List mDataset;
protected List mDataOrigin;

then inside onCreate add same source destination to both dataSet ant dataOrigin

mDataset = getObjectsFromDB();
mDataOrigin = getObjectsFromDB();

Finally use the magic function:

private void filterRecyclerView(String charText){
    charText = charText.toLowerCase();
    clearDataSet();
    if (charText.length() == 0) {
        mDataset.addAll(mDataOrigin);
    } else {
        for (User user : mDataOrigin) {
            if (user.getName().toLowerCase().contains(charText)) {
                mDataset.add(user);
            }
        }
    }
    mAdapter.notifyDataSetChanged();
}

Notice User is the list content you can replace with your Object have fun :)
