I have a custom ListView with a Custom Filter, but after entering data in the Edit_text field, I have the ListView changed and after clicking on the modified list, I get the wrong information. How do I solve this problem?
With the application launching myself, I have the correct information displayed when I click, but after I edit EditText and therefore List I have completely incorrect information when I click.
DictionaryFragment
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_dictionary, container, false);
listView = view.findViewById(R.id.dictionaryList);
editText = view.findViewById(R.id.edit_search_dict);
editText.addTextChangedListener(textWatcher);
mylist = new ArrayList<>();
SingleRow singleRow;
for (int i = 0;i<mTitle.length;i++){
singleRow = new SingleRow(mTitle[i],mDescriprion[i],images[i],mFind[i]);
mylist.add(singleRow);
}
myAdapter = new MyAdapter(getActivity(),mylist);
listView.setAdapter(myAdapter);
return view;
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
mCallback.setMyVariableX(getListOfWords()[position]);
FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
transaction.replace(R.id.fragment_container, new DetailFragment()).addToBackStack(null);
transaction.commit();
}
});

Please help me with this. I tried to solve it, but everything ended with a departure or an empty value. It is advisable to show what needs to be changed or specified in the code.
You need to get the filter data list and after that if you click on any item you get correct data.
Please try to use below code:
Create another global Array List :
ArrayList<SingleRow> finalfilters;
And initialise inside class CustomFilter extends Filter{
class CustomFilter extends Filter{
finalfilters = new ArrayList<>();
//After search set final search data into finalfilters list:
finalfilters=filters;
}
//Create one method who returns final search list:
public void getFilterList()
{
return finalfilter;
}
Call getFilterList() into your activity , set into another list in main activity class and manage click events of list item and get the filtered data through index.
