I am trying to apply filter on my custom adapter which extends BaseAdapter, in which I am facing some problems, after I filter input based on the text in EditText and check the CheckBox to select one value and if I erase the text in the EditText to search for some other thing the position of the checked checkbox changes.

Change your Adapter like this..
public class SearchableAdapter extends BaseAdapter implements Filterable,
OnCheckedChangeListener {
public SparseBooleanArray mCheckStates;
private List<ProfileBean> originalData = null;
private List<ProfileBean> filteredData = null;
private LayoutInflater mInflater;
private ItemFilter mFilter = new ItemFilter();
public SearchableAdapter(Context context, List<ProfileBean> data) {
// mCheckStates = new SparseBooleanArray(filteredData.size());
mCheckStates = new SparseBooleanArray(data.size());
this.filteredData = data;
this.originalData = data;
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return filteredData.size();
}
public Object getItem(int position) {
return filteredData.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.row, null);
holder = new ViewHolder();
holder.name = (TextView) convertView.findViewById(R.id.textView1);
holder.number = (TextView) convertView.findViewById(R.id.textView2);
holder.chk = (CheckBox) convertView.findViewById(R.id.checkBox1);
holder.chk.setTag(position);
convertView.setTag(R.layout.row, holder);
} else {
holder = (ViewHolder) convertView.getTag(R.layout.row);
}
ProfileBean bean = filteredData.get(position);
holder.name.setText(bean.getName());
holder.number.setText(bean.getNumber());
holder.chk.setOnCheckedChangeListener(null);
holder.chk.setChecked(bean.isChecked);
holder.chk.setOnCheckedChangeListener(this);
convertView.setTag(bean);
return convertView;
}
static class ViewHolder {
TextView name;
TextView number;
CheckBox chk;
}
public void toggle(int position) {
ProfileBean bean = filteredData.get(position);
bean.isChecked = !bean.isChecked;
}
public android.widget.Filter getFilter() {
return mFilter;
}
private class ItemFilter extends android.widget.Filter {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
final List<ProfileBean> list = originalData;
int count = list.size();
final ArrayList<ProfileBean> nlist = new ArrayList<ProfileBean>(
count);
String filterableString;
for (int i = 0; i < count; i++) {
ProfileBean bean = list.get(i);
filterableString = bean.getName();
if (filterableString.toLowerCase().contains(
filterString.toString().toLowerCase())) {
nlist.add(bean);
}
}
results.values = nlist;
results.count = nlist.size();
return results;
}
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
filteredData = (ArrayList<ProfileBean>) results.values;
notifyDataSetChanged();
}
}
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
int position = (Integer) buttonView.getTag();
ProfileBean profileBean = filteredData.get(position);
profileBean.isChecked = isChecked;
// mCheckStates.put((Integer) buttonView.getTag(), isChecked);
}
}
and your bean class like..
public class ProfileBean {
private String name;
private String number;
public boolean isChecked;
// private boolean checked = false ;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public ProfileBean(String name, String number) {
super();
this.name = name;
this.number = number;
}
}
And keep remaining same..try like this and let know if any problem..
Change your onBkpress method like this..
#Override
public void onBackPressed() {
phno0.clear();
for (ProfileBean bean : list) {
if (bean.isChecked) {
phno0.add(bean.getNumber());
} else {
System.out.println("..Not Checked......"
+ list.get(i).getNumber().toString());
}
}
Intent returnIntent = new Intent();
returnIntent.putStringArrayListExtra("name", phno0);
setResult(RESULT_OK, returnIntent);
finish();
}

I have listview in fragment populated from Activity with bundle , i have custom baseadapter and custom object with image and text , listview work fine with image and text , but when i do search with searchview i can get text and it's position and onclicklistener is ok without any problem, the issue is that i can't have image(logos ) with the correcte item(texttitle) , images is ranged by it's own position and not item text position
First here is my Custom object
public class Channel {
public String name;
public String logoUrl;
public Channel(String name, String logoUrl) {
this.name = name;
this.logoUrl = logoUrl;
}
#Override
public String toString() {
return "Channel {" +
"name='" + name + '\'' +
", logoUrl='" + logoUrl + '\'' +
'}';
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getLogoUrl() {
return logoUrl;
}
public void setLogoUrl(String logoUrl) {
this.logoUrl = logoUrl;
}
}
and here is my custom Base Adapter
public class ChannelAdapter extends BaseAdapter implements Filterable{
private Activity context;
private ArrayList<Channel> channelNames = new ArrayList<>(); //mList
private ArrayList<Channel> channelLogos = new ArrayList<>();
private ArrayList<Channel> tmpNames= null;
private ArrayList<Channel> tmpLogos= null;
private CustomFilter myFilter = new CustomFilter();
ColorSpace.Model model;
public ChannelAdapter(Context context, ArrayList<Channel> channels, ArrayList<Channel> logos){
this.context = (Activity) context;
this.channelNames = channels;
this.channelLogos = logos;
this.tmpNames = channels;
this.tmpLogos = logos;
// Names.addAll(channelLogos);
}
#Override
public int getCount() {
// return Names.size();
return tmpNames.size();
}
#Override
public String getItem(int position) {
return String.valueOf(tmpNames.get(position));
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row =null;
if(convertView==null) {
LayoutInflater inflater=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row=inflater.inflate(R.layout.custom_row,parent, Boolean.parseBoolean(null));
}else{
row=convertView;
}
TextView textView= (TextView) row.findViewById(R.id.textv);
ImageView image=(ImageView) row.findViewById(R.id.imageView);
textView.setText((CharSequence) tmpNames.get(position));
Picasso.with(context)
.load(String.valueOf(tmpLogos.get(position)))
.into(image);
return row;
}
#Override
public Filter getFilter() {
if (myFilter == null) {
myFilter = new CustomFilter();
}
return myFilter;
}
public class CustomFilter extends Filter{
#Override
protected FilterResults performFiltering(CharSequence constraint) {
// TODO Auto-generated method stub
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
final ArrayList<Channel> list = channelNames; //remettre channelNames
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = String.valueOf(list.get(i));
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
return results;
}
#Override
protected void publishResults(CharSequence constraint,FilterResults results) {
// TODO Auto-generated method stub
// Names.clear();
// addAll((List<Channel>) results.values);
tmpNames = (ArrayList<Channel>) results.values;
notifyDataSetChanged();
}
}
}
and finaly my OnqueryTextChange
#Override
public boolean onQueryTextChange(String newText) {
((ChannelAdapter)listView.getAdapter()).getFilter().filter(newText.toString());
}
});

i am trying to filter or Search item from Listview i am able to filter data But Problem when i clear data i mean when we blank data after filtering from Edit text then my listview item becomes blank again we have launch app and then item listview item becomes visible please tell me where am doing wrong please suggest me .

I have implement search for my application. For that I have used an adapter as well. I have loaded 30 items to the search screen. When I pressed letter z to search, then letter z belongs to 4 items out of 30 items in the list.
According to the below shown code it identifies the number 4 and shows the first 4 items out of the 30 items. When I debug inside getFilter(), it shows the filtered items correctly(I have provided a screen shot).
My problem is how can I load the filtered items. Bit confused here.

There are a couple of minor mistakes in the code. First, you need to override the getItem() method in TweetListAdaptor:
#Override
public Contact getItem(int position)
{
return mDisplayedValues.get(position);
}
Then, in the Filter's performFiltering() method, the code and name parameters are switched for the Contact constructor in the following line:
FilteredArrList.add(new Contact(mOriginalValues.get(i)._code, mOriginalValues.get(i)._name, mOriginalValues.get(i)._address, mOriginalValues.get(i)._limit));
I ran a test with 20 names, and I believe that those corrections should fix the problem.
i want to get the contact numbers in a string when user checked the contact,after which onBackpress the selected values can be stored in database.user can select multiple contacts at a time and when user returns back on the activity,the check box remains checked, so that he can see his selected contacts.
