handle list view with check box and search implemention

handle list view with check box and search implemention - android

i have a list view which has check box on each row and i`ve implemented a serch view to search in the list view. the problem is that when i search the list view and select item at postion X from the modifided list, delete the text from the search view i see the original list with the item checked in position X.
Example - list of a,b,c....z .
i can see 5 items on the list:
A
B
C
D
E
then search for z so i see only Z and check it. then i delete Z and see A-E again and A is checked.
this is my main:
public class AddRoomatesScreen extends Activity implements AdapterView.OnItemClickListener,SearchView.OnQueryTextListener {
SharedPreferences preferences;
List<String> nameList = new ArrayList<String>();
List<String> phoneList = new ArrayList<String>();
MyAdapter adapter;
Button btnSelect;
String apartmentnumber;
SearchView searchView;
ArrayList<Contact> contactList = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.add_roomate);
preferences = getSharedPreferences("appData", 0);
int apartmentNumber = preferences.getInt("apartmentNumber", 0);
apartmentnumber = Integer.toString(apartmentNumber);
getAllContacts(this.getContentResolver());
ListView lv = (ListView) findViewById(R.id.lv);
adapter = new MyAdapter(nameList,contactList);
lv.setAdapter(adapter);
lv.setOnItemClickListener(this);
lv.setItemsCanFocus(false);
lv.setTextFilterEnabled(true);
searchView = (SearchView) findViewById(R.id.search_view);
searchView.setOnQueryTextListener(this);
// adding
btnSelect = (Button) findViewById(R.id.addSelectedContacts);
btnSelect.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for(int i = 0; i<adapter.mCheckStates.size(); i++){
Contact contact = (adapter.contactsListCopy.get(adapter.mCheckStates.keyAt(i)));
new addRoommate().execute(apartmentnumber, contact.getPhoneNumber());
}
preferences = getSharedPreferences("appData", 0);
SharedPreferences.Editor editor = preferences.edit();
editor.putBoolean("roomatesLoadedFromDB", false);
editor.apply();
}
});
}
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
adapter.getFilter().filter(newText);
return false;
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
adapter.toggle(arg2);
}
public void getAllContacts(ContentResolver cr) {
Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
while (phones.moveToNext()) {
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
nameList.add(name);
phoneList.add(phoneNumber);
contactList.add(new Contact(name,phoneNumber));
}
phones.close();
}
this is my adapter:
class MyAdapter extends BaseAdapter implements CompoundButton.OnCheckedChangeListener,Filterable {
private SparseBooleanArray mCheckStates;
LayoutInflater mInflater;
TextView tv;
CheckBox cb;
ValueFilter filter;
ArrayList<Contact> contactsList;
ArrayList<Contact> contactsListCopy;
MyAdapter(List<String> nameList , ArrayList<Contact> contactsList) {
mCheckStates = new SparseBooleanArray(contactsList.size());
mInflater = (LayoutInflater) AddRoomatesScreen.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.contactsList = contactsList;
this.contactsListCopy = this.contactsList;
getFilter();
}
#Override
public int getCount() {
return contactsListCopy.size();
}
#Override
public Object getItem(int position) {
return contactsListCopy.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View vi = convertView;
if (convertView == null)
vi = mInflater.inflate(R.layout.contact_list_item, null);
TextView tv = (TextView) vi.findViewById(R.id.textView3);
cb = (CheckBox) vi.findViewById(R.id.checkBox);
Contact contact = contactsListCopy.get(position);
tv.setText(contact.getName());
cb.setTag(position);
cb.setChecked(mCheckStates.get(position, false));
cb.setOnCheckedChangeListener(this);
return vi;
}
public boolean isChecked(int position) {
return mCheckStates.get(position, false);
}
public void setChecked(int position, boolean isChecked) {
mCheckStates.put(position, isChecked);
notifyDataSetChanged();
}
public void toggle(int position) {
setChecked(position, !isChecked(position));
}
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
mCheckStates.put((Integer) buttonView.getTag(), isChecked);
}
#Override
public Filter getFilter() {
if (filter == null){
filter = new ValueFilter();
}
return filter;
}
private class ValueFilter extends Filter {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
if (constraint != null && constraint.length() > 0) {
ArrayList<Contact> temp = new ArrayList<Contact>();
for (int i = 0; i < contactList.size(); i++) {
Contact c = contactList.get(i);
if ((c.getName().toString())
.contains(constraint.toString())) {
temp.add(c);
}
}
results.count = temp.size();
results.values = temp;
} else {
results.count = contactList.size();
results.values = contactList;
}
return results;
}
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
contactsListCopy = (ArrayList<Contact>) results.values;
notifyDataSetChanged();
}
}
}
this is my model:
public class Contact{
private String phoneNumber;
private String name;
public Contact(String name , String phoneNumber){
this.phoneNumber = phoneNumber;
this.name = name;
}
public String getName() {
return name;
}
public String getPhoneNumber() {
return phoneNumber;
}
}

EDIT:
You can use the ID from the cursor as your unique id.
This code would go with the code originally posted below.
Add id to your Contact class:
public class Contact{
private long id;
private String phoneNumber;
private String name;
public Contact(long id, String name , String phoneNumber) {
this.id = id;
this.phoneNumber = phoneNumber;
this.name = name;
}
public long getId() {
return id;
}
public String getName() {
return name;
}
public String getPhoneNumber() {
return phoneNumber;
}
}
This is how you get the ID from the cursor:
public void getAllContacts(ContentResolver cr) {
Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
while (phones.moveToNext()) {
long id = phones.getLong(phones.getColumnIndex(ContactsContract.Data._ID));
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
nameList.add(name);
phoneList.add(phoneNumber);
contactList.add(new Contact(id, name, phoneNumber));
}
phones.close();
}
Your mCheckStates in the adapter changes to:
private LongSparseArray<Boolean> mCheckStates;
Some of the original answer below has been changed to match the long type used for id.
The problem is that your mCheckStates boolean map isn't kept in sync with contactsListCopy as it is filtered.
You filtered on Z so Z is now item 0,
You checked Z which sets position 0 as checked,
You redisplay the whole list. Now A is position 0 so it shows as checked.
Instead of tracking checked positions, you need to track checked contacts. To do that, you need to use the unique ID from the contact record.
Here's the changes you need to make:
Make your adapter use the unique id:
#Override
public long getItemId(int position) {
return contactsListCopy.get(position).getId();
}
Now your activity has to use the unique id instead of position:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
adapter.toggle(arg3);
}
In your adapter getView(), you have to use the ID for the check box now
cb.setTag(contact.getId());
cb.setChecked(mCheckStates.get(contact.getId(), false));
I would change some other methods just to avoid confusion:
public boolean isChecked(long id) {
return mCheckStates.get(id, false);
}
public void setChecked(long id, boolean isChecked) {
mCheckStates.put(id, isChecked);
notifyDataSetChanged();
}
public void toggle(long id) {
setChecked(id, !isChecked(id));
}

Android listview with filter issue

I have a listview of items coming from a database. Now I have put an edit text at the top of my listview. What I want is that when a user start typing in the edit text, the listview should be filtered. For example, if the user enters a letter "A", only the names starting with an "A" should appear in the list. I have used a custom adapter in my code. I asked this question many times, but haven't found a solution yet.
This is my data list activity code:
public class DataListActivity extends Activity {
ListView listView;
SQLiteDatabase sqLiteDatabase;
FoodDbHelper foodDbHelper;
Cursor cursor;
ListDataAdapter listDataAdapter;
private Button button1;
ListDataAdapter dataAdapter = null;
Button button;
DataProvider dataProvider;
ArrayList<HashMap<String, String>> namessList;
EditText inputSearch;
String search_name;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.data_list_layout);
inputSearch = (EditText)findViewById(R.id.inputSearch);
inputSearch.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changes the Text
listDataAdapter.getFilter().filter(cs);
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});
listView = (ListView) findViewById(R.id.list_View);
listDataAdapter = new ListDataAdapter(getApplicationContext(),
R.layout.row_layout) {
#Override
protected void showCheckedButton(int position, boolean value) {
// TODO Auto-generated method stub
DataProvider item = (DataProvider) listDataAdapter
.getItem(position);
Log.i("", "");
item.setSelected(value);
Button myButton = (Button) findViewById(R.id.findSelected);
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
StringBuffer responseText = new StringBuffer();
responseText
.append("The following dishes were selected...\n");
ArrayList<DataProvider> list = listDataAdapter
.getSelectedIndexes();
int sum = 0;
for (int i = 0; i < list.size(); i++) {
DataProvider dataProvider = list.get(i);
sum = sum + dataProvider.getCalorie();
responseText.append("\n" + dataProvider.getName()
+ " : " + dataProvider.getCalorie()
+ " kcal"
);
}
Toast.makeText(getApplicationContext(), ""+responseText+"\n"+"................................."
+"\n"+"Total Calories In Your Menu Is : " +sum,
Toast.LENGTH_LONG).show();
}
});
}
};
listView.setAdapter(listDataAdapter);
foodDbHelper = new FoodDbHelper(getApplicationContext());
sqLiteDatabase = foodDbHelper.getReadableDatabase();
cursor = foodDbHelper.getInformations(sqLiteDatabase);
if (cursor.moveToFirst()) {
do {
String name, quantity, fat, protein, sugar, vitamins;
boolean selected = false;
String names = null;
Integer calorie;
name = cursor.getString(0);
quantity = cursor.getString(1);
calorie = Integer.valueOf(cursor.getString(2));
fat = cursor.getString(3);
protein = cursor.getString(4);
sugar = cursor.getString(5);
vitamins = cursor.getString(6);
DataProvider dataProvider = new DataProvider(name, quantity,
calorie, fat, protein, sugar, vitamins, names, selected);
listDataAdapter.add(dataProvider);
} while (cursor.moveToNext());
}
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String name = (String) ((TextView) view
.findViewById(R.id.text_dish_name)).getText();
String quantity = (String) ((TextView) view
.findViewById(R.id.text_dish_quantity)).getText();
String calorie = (String) ((TextView) view
.findViewById(R.id.text_dish_calorie)).getText();
String fat = (String) ((TextView) view

.findViewById(R.id.text_dish_vitamins)).getText();
String.valueOf(parent.getItemAtPosition(position));
Toast.makeText(getApplicationContext(),
"dish name is : " + name, Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getApplicationContext(),
Detail.class);
intent.putExtra("Dish name", name);
intent.putExtra("Dish quantity", quantity);
intent.putExtra("Dish calorie", calorie);
intent.putExtra("Dish fat", fat);
intent.putExtra("Dish protein", protein);
intent.putExtra("Dish sugar", sugar);
intent.putExtra("Dish vitamins", vitamins);
startActivity(intent);
}
});
}
public void gobackk(View view) {
Intent intent = new Intent(this, MainMenu.class);
startActivity(intent);
}

Use the addTextChangedListener() method of your EditText. It would look something like this
inputSearch = (EditText)findViewById(R.id.editText);
....
....
listView.setAdapter(listDataAdapter);
inputSearch.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changes the Text
listDataAdapter.getFilter().filter(cs);
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});

Instead of EditText can you use SearchView in your Xml?? If that's not problem then here you have complete working code with adapter and xml everything.!
XML
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MyActivity" >
<SearchView
android:id="#+id/searchPlayers"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:background="#color/Blue600"
android:layout_alignParentTop="true" />
<ListView
android:id="#+id/playersList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/searchPlayers"
android:divider="#color/Teal"
android:dividerHeight="1dp"
android:scrollingCache="false"
android:smoothScrollbar="true" />
Let your mainActivity extends Activity implements SearchView.OnQueryTextListener, Filterable,SearchView.OnCloseListener
Inside onCreate() of MainActivity:
searchView = (SearchView) findViewById(R.id.searchPlayers);
searchView.setOnQueryTextListener(this);
searchView.setOnCloseListener(this);
searchView.setQueryHint("Search by Player");
Override these in you MainActivity:
#Override
public boolean onQueryTextChange(String newText) {list will get filtered as per input.
if (TextUtils.isEmpty(newText)) {
listView.clearTextFilter();
customAdapter.getFilter().filter("");
} else {
if(customAdapter!=null){
PlayersCustomAdapter ca = (PlayersCustomAdapter) listView.getAdapter();
ca.getFilter().filter(newText);
}
}
return true;
}
#Override
public boolean onQueryTextSubmit(String abc) {
return false;
}
#Override
public android.widget.Filter getFilter() {
return null;
}
#Override
public boolean onClose() {//it will set the list to initial position when searchView is closed
customAdapter.getFilter().filter("");
return false;
}
Here is the Custom Adapter..!
public class PlayersCustomAdapter extends BaseAdapter implements Filterable {
Context context;
ArrayList<PlayersMapper> playersMapperList, filteredplayersMapperList;
public PlayersCustomAdapter(Context context, ArrayList<PlayersMapper> list) {
super();

position of checkbox get change

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,

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);

and your bean class like..
public class ProfileBean {

// private boolean checked = false ;
public String getName() {

}
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();
}

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.

how to get the checked contacts details in a string

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.

Android custom search in sectioned listview/baseadapter

Hello guys I want to search my custom/sectioned listview. This is what I've tried so far:
MyAdapter.class:
public class MyAdapter extends BaseAdapter implements SectionIndexer, Filterable {
private ArrayList<String> filteredData = null;
private ItemFilter mFilter = new ItemFilter();
private ArrayList<String> stringArray;
private Context context;
public MyAdapter(Context _context, ArrayList<String> arr) {
stringArray = arr;
filteredData = arr;
context = _context;
}
public int getCount() {
return stringArray.size();
}
public Object getItem(int arg0) {
return stringArray.get(arg0);
}
public long getItemId(int arg0) {
return 0;
}
public View getView(int position, View v, ViewGroup parent) {
LayoutInflater inflate = (( Activity ) context).getLayoutInflater();
View view = (View) inflate.inflate(R.layout.listview_row, null);
LinearLayout header = (LinearLayout) view.findViewById(R.id.section);
String label = stringArray.get(position);
char firstChar = label.toUpperCase().charAt(0);
if (position == 0) {
setSection(header, label);
} else {
String preLabel = stringArray.get(position - 1);
char preFirstChar = preLabel.toUpperCase().charAt(0);
if (firstChar != preFirstChar) {
setSection(header, label);
} else {
header.setVisibility(View.GONE);
}
}
TextView textView = (TextView) view.findViewById(R.id.textView);
textView.setText(label);
return view;
}
private void setSection(LinearLayout header, String label) {
TextView text = new TextView(context);
//#33D633
header.setBackgroundColor(0xff33D633);
text.setTextColor(Color.BLACK);
text.setText(label.substring(0, 1).toUpperCase());
text.setTextSize(20);
text.setPadding(5, 0, 0, 0);
text.setGravity(Gravity.CENTER_VERTICAL);
header.addView(text);
}
public int getPositionForSection(int section) {
if (section == 35) {
return 0;
}
for (int i = 0; i < stringArray.size(); i++) {
String l = stringArray.get(i);
char firstChar = l.toUpperCase().charAt(0);
if (firstChar == section) {
return i;
}
}
return -1;
}
public int getSectionForPosition(int arg0) {
return 0;
}
public Object[] getSections() {
return null;
}
public Filter getFilter() {
return mFilter;
}
private class ItemFilter extends Filter {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
final List<String> list = stringArray;
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = list.get(i);
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
return results;
}
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredData = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}
MainActivity.class:
String searchString;
MyAdapter adapter;
ArrayList<String> stringList, searchResults;
etSearch.addTextChangedListener(new TextWatcher (){
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
public void onTextChanged(CharSequence cs, int arg1, int arg2,

// TODO Auto-generated method stub
Log.e("TAG", cs.toString());
adapter.getFilter().filter(cs.toString());
}
});
private ArrayList<String> InitListViewData() {
String[] allWords = dbHelper.getAllWords();
stringList = new ArrayList<String>(Arrays.asList(allWords));
return stringList;
}
private void initControls(View rootView) {
etSearch = (EditText) rootView.findViewById(R.id.etSearch);
listView1 = (ListView) rootView.findViewById(R.id.myListView);// list view finding
// Adding data to array lists
listView1.setTextFilterEnabled(true);
dbConnect();
stringList = InitListViewData();
adapter = new MyAdapter(getActivity(), stringList);
listView1.setAdapter(adapter);
SideBar indexBar = (SideBar) rootView.findViewById(R.id.sideBar);
indexBar.setListView(listView1);
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int pos,
long id) {
//TextView tvChild = (TextView) v.findViewById(R.id.tvChild);
String selected = parent.getItemAtPosition(pos).toString();
//tvChild.getText().toString().trim();
Toast.makeText(getActivity(), "" + selected, Toast.LENGTH_SHORT).show();
}
});
}
But it's not filtering at all :( I wonder why. I already attached addTextChangedListener to my editText and added getFilter method in my BasedAdapter to no avail. Any ideas? I would gladly appreciate your help. thanks!

you can do custom search like this, pass the string value from editext on text changed method to this method.
public ArrayList<String> matchedValue(String value)
{
ArrayList<String> local=new ArrayList<String>();
for(int i=0;i<Stringarray.size();i++)
{
if(Stringarray.contains(value))
{
local.add(Stringarray.get(i));
}
}
return local;
}
it will return the matched value then update the listview adapter using this returned arraylist.
