@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
View listItemView = convertView;
if(listItemView == null) {
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.main_listview, parent, false);

In MAIN ACTIVITY, the Action Bar SEARCH VIEW in the Main activity, what should do? here
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.list_menu, menu);
MenuItem menuItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) menuItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
return true;
}
});
return super.onCreateOptionsMenu(menu);
}
These are the Objects that i added to my array list, i want to search in some of them and if the string in the array is matching then the array list can be shown in the list. but if the Name doesnt have a matching string it should go!
private void smallaaray() {
array = new ArrayList<Name>();
array.add(new Name("1", "akhil","", "", R.drawable.0,
R.string.0, "",
"","","","","","","","","","","","","",R.drawable.0,R.drawable.0,R.drawable.0,R.drawable.0));
Please Help!
Found A Simple & Complex Solution.
SearchView searchView = (SearchView) menuItem.getActionView();
searchView.setQueryHint("Search All Data!");
searchView.setOnQueryTextListener (new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String q) {
return false;
}
@Override
public boolean onQueryTextChange(String s) {
if (BUYED_APP == false){
Toast.makeText(NonDetailDrugActivity.this, "Your are Searching on a Short list of 10 Drugs Only.\nPlease Subscribe to Gain Access to Full Data!", Toast.LENGTH_LONG).show();
}
filter = new ArrayList<>();
filter.clear();
if (s.length() == 0) {
filter.addAll(array);
} else {
for (Name post : array) {
String filterPattern = s.toLowerCase().trim();
if (post.getSanskritName().toLowerCase().contains(filterPattern)) {
filter.add(post);
} else {
filter.retainAll(array);
if (post.getScientificName().toLowerCase().contains(filterPattern)) {
filter.add(post);
} else {
filter.retainAll(array);
if (post.getFamilyName().toLowerCase().contains(filterPattern)) {
filter.add(post);
} else {
filter.retainAll(array);
if (post.getOtherName().toLowerCase().contains(filterPattern)) {
filter.add(post);
}else {
filter.retainAll(array);
if (post.getAmayikaPrayogam().toLowerCase().contains(filterPattern)) {
filter.add(post);
}else {
filter.retainAll(array);
if (post.getYogas().toLowerCase().contains(filterPattern)) {
filter.add(post);
}else {
filter.retainAll(array);
if (post.getKarma().toLowerCase().contains(filterPattern)) {
filter.add(post);
} else {
filter.retainAll(array);
if (post.getMalayalamNameId().toLowerCase().contains(filterPattern)) {
filter.add(post);
}
}
}
}
}
}
}
}
}
}
adap.clear();
adap.addAll(filter);
adap.notifyDataSetChanged();
return true;
}
});
searchView.setOnCloseListener(new SearchView.OnCloseListener() {
@Override
public boolean onClose() {
clearSearch();
searchView.onActionViewCollapsed();
return true;
}
});
&
private void clearSearch(){
adap.clear();
filter.clear();
smallaaray();
adap.addAll(array);
adap.notifyDataSetChanged(); }
That way! I made my Search possible.! Thank you SO much for the Help Everyone.
