Without seeing your activity code, I would suggest you try this approach - also assuming you have all the files created as stated above;

In your results activity,

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.core_actions, menu);

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

    searchView.setIconifiedByDefault(false);
    searchView.setQueryHint(getString(R.string.search_hint));

    searchView.setOnQueryTextListener(this);

    return true;
}

Remember that this is the activity that has your data that you want to make searchable:

You must implement the SearchView.OnQueryTextListener interface in the same activity:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_search:
            ProductsResulstActivity.this.finish();

            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

@Override
public boolean onQueryTextSubmit(String query) {
    return false;
}

@Override
public boolean onQueryTextChange(String newText) {

    productFilterAdapter.getFilter().filter(newText);

    if (TextUtils.isEmpty(newText)) {
         listView.clearTextFilter();
     }
    else {
       listView.setFilterText(newText);
    }

    return true;
}

productFilterAdapter is the adapter that you must create beforehand.

It should implement Filterable interface. I hope this helps.

If you need further assistance, please let me know. Good luck
