How to search in Custom List View
Hi Im having a custom List View but i am unable to code the right way for only filter/search the particular Person Name in CustomListView(Basically i am getting this from JSON and stored in ArrayList)... Please anyone help me with this method filter in CustomListViewAdapter.java
Here is my Main_Activity.Java Code
array111.add(new AshTable(test1, test2, test3, test4, test5, test6, test7, test8, test9, test10, test11, test12, test13, test14, test15, test16, test17, test18, test19, test20, test21, test22, test23, test24, test25, test26, test27, test28, test29, test30, test31, test32, test33, test34, test35, test36, test37, test38, test39, test40, test41, test42));
}
} catch (JSONException e) {
e.printStackTrace();
}
final CustomListViewAdapter adapter = new CustomListViewAdapter(getActivity(), R.layout.home_list_view, array111);
lstv11.setAdapter(adapter);
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
String text = inputSearch.getText().toString().toLowerCase(Locale.getDefault());
adapter.filter(text);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
});
mSwipeRefreshLayout.setRefreshing(false);
}
}
Here is my CustomListViewAdapter.java code
public class CustomListViewAdapter extends ArrayAdapter implements Filterable {
ArrayList<AshTable> prod;
Context context;
int resource;
public CustomListViewAdapter(Context context, int resource, ArrayList<AshTable> prod) {

Basically what you have to do is to check each value in the list to see if it meets the filter requirements, and then add that to a temporary list. Once you have a complete list, you swap out the temp list into the array adapter list, in your case prod. You also have to account for no filter, or retrieving the complete list, so you will want to keep a reference to that list as well. All you have to do is create another array, and assign a copy of the original list to the reference list. All this might look something like this:
//Create reference list to keep track of complete list.
ArrayList<AshTable> refList = new ArrayList<AshTable>();
public CustomListViewAdapter(Context context, int resource, ArrayList<AshTable> prod) {
super(context, resource, prod);
this.context=context;
this.resource=resource;
this.prod=prod;
this.refList = prod;
}
//Filter method
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
if (charText.length() == 0) {
//if there is no data to filter, replace complete list
prod.clear();
prod.addAll(refList);
} else {
//Temp array to store values that meet filter requirements
ArrayList<AshTable> tempTable = new ArrayList<AshTable>();
for(AshTable pro : prod){
//here you can add any other filter requirements
//just iterate through each item and check it.
if(pro.getPersonname().contains(charText)){
tempTable.add(pro);
}
}
//put filtered data into arraylist
prod.clear();
prod.addAll(tempTable);
}
notifyDataSetChanged();
}

Please use this code :
array111.add(new AshTable(test1, test2, test3, test4, test5, test6, test7, test8, test9, test10, test11, test12, test13, test14, test15, test16, test17, test18, test19, test20, test21, test22, test23, test24, test25, test26, test27, test28, test29, test30, test31, test32, test33, test34, test35, test36, test37, test38, test39, test40, test41, test42));
}
} catch (JSONException e) {
e.printStackTrace();
}
final CustomListViewAdapter adapter = new CustomListViewAdapter(getActivity(), R.layout.home_list_view, array111);
lstv11.setAdapter(adapter);
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,

if (YourClassName.this.adapter != null)
((YourAdapterClassName) YourClassName.this.adapter).getFilter().filter(arg0);
}
});

Make change in your adapeter class according to this sample code and concentrate on getFilter method although I have pasted complete adapter class for your reference.
public class CustomListAdapter extends BaseAdapter
{
private Activity activity;
private LayoutInflater inflater;
private List<Movie> movieItems;
private List<Movie> movieItemSearched = null;
private List<Movie> originalMovieList;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
public CustomListAdapter(Activity activity, List<Movie> movieItems) {
this.activity = activity;
this.movieItems = movieItems;
this.originalMovieList = new ArrayList<Movie>(movieItems);
this.movieItemSearched = new ArrayList<Movie>();
this.movieItemSearched.addAll(movieItems);
}
//Add Below Method
public void reloadData(){
this.originalMovieList = new ArrayList<Movie>(movieItems);
notifyDataSetChanged();
}
@Override
public int getCount() {
return movieItems.size();
}
@Override
public Object getItem(int location) {
return movieItems.get(location);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_row, null);
if (imageLoader == null)
imageLoader = AppController.getInstance().getImageLoader();
NetworkImageView thumbNail = (NetworkImageView) convertView
.findViewById(R.id.thumbnail);
TextView title = (TextView) convertView.findViewById(R.id.title);
TextView rating = (TextView) convertView.findViewById(R.id.rating);
TextView genre = (TextView) convertView.findViewById(R.id.genre);
TextView year = (TextView) convertView.findViewById(R.id.releaseYear);
TextView appuser = (TextView) convertView.findViewById(R.id.appuser);
TextView reg = (TextView) convertView.findViewById(R.id.reg);
// LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(100, 100);
// iv.setLayoutParams(layoutParams);
// getting movie data for the row
Movie m = movieItems.get(position);
// thumbnail image
thumbNail.setImageUrl(m.getThumbnailUrl(), imageLoader);
// title
title.setText(m.getTitle());
// rating
rating.setText(m.getRating());
// genre
genre.setText(m.getGenre());
appuser.setText(m.getApp_user());
reg.setText(m.getReg());
year.setText(String.valueOf(m.getYear()));
return convertView;
}
public Filter getFilter(ComponentName cn) {
return new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
final List<Movie> list = originalMovieList;
int count = list.size();
final ArrayList<Movie> nlist = new ArrayList<Movie>(count);
String filterableString1,filterableString2;
/*
for (int i = 0; i < count; i++) {
filterableString = list.get(i).getTitle();
if (filterableString.toLowerCase().contains(filterString)) {
// nlist.add(filterableString);
nlist.add(list.get(i));
}
}
*/
for (Movie movie: originalMovieList) {
filterableString1 = movie.getTitle();
filterableString2 = movie.getRating();
if (filterableString1.toLowerCase().contains(filterString)||filterableString2.toLowerCase().contains(filterString)) {
// nlist.add(filterableString);
nlist.add(movie);
}
}
results.values = nlist;
results.count = nlist.size();
return results;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
movieItems.clear();
movieItems.addAll((ArrayList<Movie>) results.values);
notifyDataSetChanged();
}
};
}
}
And Use this Method like this in your search View:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
// Inflate menu to add items to action bar if it is present.
inflater.inflate(R.menu.main, menu);
SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView search = (SearchView) menu.findItem(R.id.action_search).getActionView();
search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));
search.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
adapter.getFilter(getComponentName()).filter(newText);
adapter.notifyDataSetChanged();
return false;
}
});
return true;
}
