I have the code for TextWatcher that changes 2 different listViews using 2 different ArrayAdapters.
private TextWatcher createAndReturnTextWatcher()
{
final List<String> list = dbExtractor.getDataForSearchAdapters();
adapterForSearch = new MyAdapter(this, R.layout.list_item2, R.id.product_name,
list);
adapter = new ArrayAdapter(this, R.layout.list_item2, R.id.product_name,
dbExtractor.getDataForSearchAdapters());
TextWatcher watcher1;
watcher1 = new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
if (cs.length() == 0) {
lv.setAdapter(null);
lv2.setAdapter(null);
dc.clickedOnce = true;
dc.decrement();
dc.checkDimCounter();
} else {
lv.setAdapter(adapterForSearch);
adapterForSearch.getFilter().filter(cs);
lv2.setAdapter(adapter);
adapter.getFilter().filter(cs);
if (dc.clickedOnce) {
dc.increment();
dc.checkDimCounter();
dc.clickedOnce = false;
}
}
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}
@Override
public void afterTextChanged(Editable arg0) {
}
};
return watcher1;
}
The question is:
Why this works properly when I use one standart ArrayAdapter class, and one custom ArrayAdapter class, but it doesn't work if I try to use both custom ArrayAdapters. This just changes both listViews like they both use one of custom adapters?
Thanks in advance!
MY CUSTOM ADAPTERS
1st
public class MyTurkishAdapter extends ArrayAdapter {
protected Filter myTurkFilter;
protected List<String> mObjects;
protected List<String> mOriginalValues;
public MyTurkishAdapter(Context context, int resource, int textViewResourceId, List objects) {
super(context, resource, textViewResourceId, objects);
myTurkFilter = new MyTurkFilter();
mObjects = objects;
}
@Override
public Filter getFilter() {
return myTurkFilter;
}
private class MyTurkFilter extends Filter
{
@Override
protected FilterResults performFiltering(CharSequence prefix) {
FilterResults results = new FilterResults();
if (mOriginalValues == null) {
{
mOriginalValues = new ArrayList<String>(mObjects);
}
}
if (prefix == null || prefix.length() == 0) {
ArrayList<String> list;
{
list = new ArrayList<>(mOriginalValues);
}
results.values = list;
results.count = list.size();
} else {
java.lang.String prefixString = prefix.toString().toLowerCase();
ArrayList<String> values;
{
values = new ArrayList<>(mOriginalValues);
}
final int count = values.size();
final ArrayList<String> newValues = new ArrayList<String>();
for (int i = 0; i < count; i++) {
final String value = values.get(i);
final java.lang.String valueText = value.toLowerCase();
if (valueText.startsWith(prefixString)) {
newValues.add(reverse(value));
}
}
results.values = newValues;
results.count = newValues.size();
}
return results;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
mObjects.clear();
mObjects.addAll((List<String>) results.values);
if (results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
}
private java.lang.String reverse(java.lang.String couples)
{
java.lang.String[] arr = couples.split(" — ");
return arr[1]+ " — " + arr[0];
}
}
2nd
public class MyAdapter extends ArrayAdapter {
protected Filter filter;
protected List<String> mObjects;
protected List<String> mOriginalValues;
public MyAdapter(Context context, int resource, int textViewResourceId, List<String> objects) {
super(context, resource, textViewResourceId, objects);
filter = new MyFilter();
mObjects = objects;
}
@Override
public Filter getFilter() {
return filter;
}
private class MyFilter extends Filter
{
@Override
protected FilterResults performFiltering(CharSequence prefix) {
FilterResults results = new FilterResults();
if (mOriginalValues == null) {
{
mOriginalValues = new ArrayList<String>(mObjects);
}
}
if (prefix == null || prefix.length() == 0) {
ArrayList<String> list;
{
list = new ArrayList<String>(mOriginalValues);
}
results.values = list;
results.count = list.size();
} else {
java.lang.String prefixString = prefix.toString().toLowerCase();
ArrayList<String> values;
{
values = new ArrayList<String>(mOriginalValues);
}
final int count = values.size();
final ArrayList<String> newValues = new ArrayList<String>();
//DictionaryActivity2.turkish.clear();
for (int i = 0; i < count; i++) {
final String value = values.get(i);
final java.lang.String valueText = value.toString().toLowerCase();
if (valueText.startsWith(prefixString)) {
newValues.add(value);
}
}
results.values = newValues;
results.count = newValues.size();
}
return results;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
mObjects.clear();
mObjects.addAll((List<String>) results.values);
if (results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
}
}
P.S. They have just one line difference. I know about Template Method pattern and will implement this right after I'll find the answer for this question :)
