I am trying to implement a search option for listview which also has a checkbox in each row.
I am getting the friends list from Google plus account and showing them in the listview
using customAdapter.
The friend's name, image and id are stored in hashmap.
The problem for e.g.
I select first and second item and then type a text in the search box - the results are shown with the first item and second item being checked automatically.
Or another example:
When I select an item in search results and now clear the search text the checkbox gets cleared too.
How do I fix this issue?
Friends.java
ArrayList<HashMap<String, String>> friendList;
ArrayList<HashMap<String, String>> searchResults;
static boolean[] isChecked;
static boolean[] isSearchChecked;
private EditText searchText;
static int listPerson = 1;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
setContentView(R.layout.activityfriends);
res = this.getResources();
searchText = (EditText) findViewById(R.id.searchText);
searchText.setOnClickListener(this);
friendList = new ArrayList<HashMap<String, String>>();
searchResults = new ArrayList<HashMap<String, String>>();
list = (ListView)findViewById(R.id.friend_list);
searchText.addTextChangedListener(new TextWatcher()
{
public void afterTextChanged(Editable s)
{
}
public void beforeTextChanged(CharSequence s, int start, int count, int after)
{
}
public void onTextChanged(CharSequence s, int start, int before, int count)
{
listofperson = 2;
searchResults.clear();
if (friendList.size() > 0 )
{
for (HashMap<String, String> map : friendList)
{
if(map.get(KEY_DISPLAY_NAME).toLowerCase().contains(s.toString().toLowerCase()))
{
HashMap<String, String> hashMap = new HashMap<String, String>();
hashMap.put(KEY_ID, map.get(KEY_ID));
hashMap.put(KEY_DISPLAY_NAME, map.get(KEY_DISPLAY_NAME));
hashMap.put(KEY_IMAGEPROFILE_URL, map.get(KEY_IMAGEPROFILE_URL));
searchResults.add(hashMap);
isSearchChecked = new boolean[searchResults.size()];
for (int i = 0; i < isSearchChecked.length; i++)
{
isSearchChecked[i] = false;
}
}
}
adapter= new FriendsAdapter(Friends.this, searchResults);
list.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
});
// Click event for single list row
list.setOnItemClickListener(new OnItemClickListener()
{
private CheckBox cb;
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id)
{
if (listPerson == 1)
{
String person_ID = friendList.get(position).get(KEY_ID);
String person_DISPLAY_NAME = friendList.get(position).get(KEY_DISPLAY_NAME);
cb = (CheckBox) view.findViewById(R.id.checkBox);
//cb.setChecked(true);
cb.performClick();
if (cb.isChecked())
{
//add to be database
}
else if (!cb.isChecked())
{
//remove from database
}
}
else
{
String SearchResult_person_ID = searchResults.get(position).get(KEY_ID);
String SearchRResult_person_DISPLAY_NAME = searchResults.get(position).get(KEY_DISPLAY_NAME);
cb = (CheckBox) view.findViewById(R.id.checkBox);
//cb.setChecked(true);
cb.performClick();
if (cb.isChecked())
{
//add to database
}
else if (!cb.isChecked())
{
//remove from database
}
}
}
});
}
OnResult of Gplus client I have the following line of code:
PersonBuffer personBuffer = peopleData.getPersonBuffer();
try
{
friendsCount = personBuffer.getCount();
for (int i = 0; i < friendsCount; i++)
{
HashMap<String, String> map = new HashMap<String, String>();
map.put(KEY_ID, personBuffer.get(i).getId());
map.put(KEY_DISPLAY_NAME, personBuffer.get(i).getDisplayName());
map.put(KEY_IMAGEPROFILE_URL, personBuffer.get(i).getImage().getUrl());
friendList.add(map);
}
}
finally
{
personBuffer.close();
}
if (friendCount > 0)
{
isChecked = new boolean[peopleCount];
for (int i = 0; i < isChecked.length; i++)
{
isChecked[i] = false;
}
adapter = new FriendsAdapter(this, friendList);
list.setAdapter(adapter);
adapter.notifyDataSetChanged();
}

I'm in learning about add view programmatically. But, I'm in confusing now.
I have data, there are idpatient, idheader. Patient can have more than one ID header. When I input idpatient, it will add listview (with custom adapter) programmatically. The number of listview is same with the number of ID header.
I want to set in each listview with data patient group by ID header..
So far, I add search view when loop adding listview, but when I input one ID header to seacrh view, all of listview will view the same data according to ID header in search view..
I'm sorry for the long explanation. Can anybody help me to solve this problem?
Thanks in advance

I'm developing an android app which has a custom listview with a checkbox. I want to pass all the checked items from one activity to another. how should I pass them? and where should I manage the checkbox (to get all the checked items) in the custom adapter or the activity?
Note: I retrieve all the data from my server using json response.
Here's my Model :
public class Groups {
public String name;
public boolean selected= false;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean isSelected() {
return selected;
}
public void setSelected(boolean selected) {
this.selected = selected;
}
public Groups() {
}
}
My Adapter:
public class AdapterMainActivity extends BaseAdapter{
Activity activity;
private LayoutInflater inflater;
List<Groups> groupsList;
public AdapterMainActivity(Activity activity, List<Groups> groupses) {
this.activity = activity;
this.groupsList = groupses;
}
#Override
public int getCount() {
return groupsList.size();
}
#Override
public Object getItem(int position) {
return groupsList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final 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.custom_list, null);
TextView name = (TextView) convertView.findViewById(R.id.textViewName);
final CheckBox checkBox = (CheckBox) convertView.findViewById(R.id.checkBox);
final Groups groups = groupsList.get(position);
name.setText(groupsList.get(position).getName());
checkBox.setChecked(groups.selected);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
groups.selected = isChecked;
MainActivity.getInstance().updateArrayList(groupsList);
}
});
}
return convertView;
}
}
MainActivity:
public class MainActivity extends AppCompatActivity {
ListView listViewGroups;
Button buttonSentToActivity;
List<Groups> groupsList;
List<Groups> resultGroupList;
ArrayList<Boolean> areChecked;
List<String> finalArray;
private AdapterMainActivity adapterMainActivity;
static MainActivity yourActivity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
yourActivity = this;
groupsList= new ArrayList<Groups>();
resultGroupList= new ArrayList<Groups>();
ReadGroup(37);
adapterMainActivity = new AdapterMainActivity(this, groupsList);
listViewGroups = (ListView) findViewById(R.id.listViewGroups);
listViewGroups.setAdapter(adapterMainActivity);
buttonSentToActivity = (Button) findViewById(R.id.buttonSendTo2Activity);
buttonSentToActivity.setOnClickListener(buttonSentToActivityListener);
Log.e("Group list size ", String.valueOf(groupsList.size()));
finalArray = new ArrayList<>();
for (int i = 0; i < resultGroupList.size(); i++) {
if (resultGroupList.get(i).selected) {
finalArray.add(resultGroupList.get(i).getName());
Log.e("final array size", String.valueOf(finalArray.size()));
}
}
}
public void ReadGroup(long cid) {
Response.Listener<String> responseListener = new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response.toString());
JSONArray readArray = jsonObject.getJSONArray("groups");
for (int i = 0; i < readArray.length(); i++) {
Log.e("i is: ", String.valueOf(i));
JSONObject jssonRow = readArray.getJSONObject(i);
String groupName = jssonRow.getString("name");
Groups groups = new Groups();
groups.setName(groupName);
Log.e("NAME is: ", groupName);
groupsList.add(groups);
}
} catch (JSONException e) {
e.printStackTrace();
}
adapterMainActivity.notifyDataSetChanged();
}
};
Log.e("Client id is: ", String.valueOf(cid));
ReadGroupRequesr readGroupRequest = new ReadGroupRequesr(cid, responseListener);
RequestQueue queue = Volley.newRequestQueue(MainActivity.this);
queue.add(readGroupRequest);
Log.e("out of the loop", "");
}
public static MainActivity getInstance() {
return yourActivity;
}
public void updateArrayList(List<Groups> arrayList) {
this.resultGroupList = arrayList;
}
View.OnClickListener buttonSentToActivityListener = new View.OnClickListener() {
#Override
public void onClick(View view) {
//Bundle b= new Bundle();
//b.putStringArrayList("arrayList", (ArrayList<String>) finalArray);
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
intent.putStringArrayListExtra("arrayList", (ArrayList<String>) finalArray);
//intent.putExtras(b);
Log.e("final array size", String.valueOf(finalArray.size()));
startActivity(intent);
}
};
}
At the very first, manage your checkboxes :
In your activity class add a boolean array or arraylist having size same as your list array size and initialize it with all value as false initially :
String[] titlesArray;
ArrayList<Boolean> arrChecked;
// initialize arrChecked boolean array and add checkbox value as false initially for each item of listview
arrChecked = new ArrayList<Boolean>();
for (int i = 0; i < titles.size(); i++) {
arrChecked.add(false);
}
Now replace your adapter class with this :
class VivzAdapter extends ArrayAdapter<String> implements OnCheckedChangeListener {
Context context;
int[] images;
String[] titlesArray, descrptionArray;
List<Integer> positions = new ArrayList<Integer>();
ArrayList<Boolean> arrChecked;
VivzAdapter(Context context, String[] titles, int[] images, String[] description, ArrayList<Boolean> arrChecked) {
super(context, R.layout.single_row, R.id.textView1, titles);
this.context = context;
this.images = images;
this.titlesArray = titles;
this.descrptionArray = description;
this.arrChecked = arrChecked;
}
class MyViewHolder {
ImageView myImage;
TextView myTitle;
TextView myDescription;
CheckBox box;
MyViewHolder(View v) {
myImage = (ImageView) v.findViewById(R.id.imageView1);
myTitle = (TextView) v.findViewById(R.id.textView1);
myDescription = (TextView) v.findViewById(R.id.textView2);
box = (CheckBox) v.findViewById(R.id.checkBox1);
}
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
MyViewHolder holder = null;
if (row == null) {
// 1.ºtime
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//row contem RelativeLayout(root) em single_row.xml
row = inflater.inflate(R.layout.single_row, parent, false);
holder = new MyViewHolder(row);
row.setTag(holder);
//Log.d("VIVZ", "Creating a new Row");
} else {
//reciclamos aqui, qeremos usar antigo objecto holder
holder = (MyViewHolder) row.getTag();
//Log.d("VIVZ", "Recycling stuff");
}
holder.myImage.setImageResource(images[position]);
holder.myTitle.setText(titlesArray[position]);
holder.myDescription.setText(descrptionArray[position]);
//set position as id
holder.box.setId(position);
//set onClickListener of checkbox rather than onCheckedChangeListener
holder.box.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
int id = v.getId();
if (arrChecked.get(id)) {
//if checked, make it unchecked
arrChecked.set(id, false);
} else {
//if unchecked, make it checked
arrChecked.set(id, true);
}
}
});
//set the value of each checkbox from arrChecked boolean array
holder.box.setChecked(arrChecked.get(position));
return row;
}
}
After that, implement click listener of send button say btnSend button (I am considering that you are sending your data from one activity to another activity on click of send button) :
btnSend.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<String> arrTempList = new ArrayList();
for(int i=0; i<titles.size(); i++){
if(arrChecked.get(i) == true){
arrTempList.add(titles[i]);
}
}
// here you can send your arrTempList which is having checked items only
}
});
Here's the solution for this Question:
My adapter:
public class ChooseContactsAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
public ArrayList<Contacts> contactsList;
public CheckBox checkBoxAdapter;
public ChooseContactsAdapter(Activity activity, ArrayList<Contacts> group) {
this.activity = activity;
this.contactsList = group;
}
#Override
public int getCount() {
return contactsList.size();
}
#Override
public Object getItem(int position) {
return contactsList.get(position);
}
#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.custom_choose_contacts_sms,
null);
final TextView fNAme = (TextView) convertView.findViewById(R.id.textViewCustomSMSSelectContactFName);
TextView LName = (TextView) convertView.findViewById(R.id.textViewCustomSMSSelectContactLName);
checkBoxAdapter = (CheckBox) convertView.findViewById(R.id.checkBoxSelectContact);
checkBoxAdapter.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
CheckBox cb = (CheckBox) view;
Contacts contacts = (Contacts) cb.getTag();
contacts.setSelected(cb.isChecked());
Toast.makeText(activity.getApplicationContext(),
"Clicked on Checkbox: " + cb.getText() +
" is " + cb.isChecked(),
Toast.LENGTH_LONG).show();
}
});
final Contacts contacts = contactsList.get(position);
fNAme.setText(contacts.getContactFName());
LName.setText(contacts.getContactLName());
checkBoxAdapter.setChecked(contacts.isSelected());
checkBoxAdapter.setTag(contacts);
}
return convertView;
}
}
In my activity I have button to go from 1 activity to the 2 activity:
private View.OnClickListener buttonSubmitGroupListener =new View.OnClickListener() {
#Override
public void onClick(View view) {
List <Integer> contactsIDArray= new ArrayList<Integer>();
List<Contacts> arrayOfContacts= chooseContactsAdapter.contactsList;
for(int i=0; i< arrayOfContacts.size(); i++){
Contacts contacts= arrayOfContacts.get(i);
if(contacts.isSelected()==true){
contactsIDArray.add(contacts.getContactID());
}
}
for (int i = 0; i < contactsIDArray.size(); i++) {
Log.e("Id Array size ", String.valueOf(contactsIDArray.size()));
Log.e("Selected id ", String.valueOf(contactsIDArray.get(i)));
}
intent = new Intent(getApplicationContext(), SendSMSActivity.class);
Bundle b = new Bundle();
b.putIntegerArrayList("checkedContacts", (ArrayList<Integer>) contactsIDArray);
intent.putExtras(b);
startActivity(intent);
}
};
Second Activity add this code:
Bundle b = getIntent().getExtras();
List<Integer> result = new ArrayList<Integer>();
result = b.getIntegerArrayList("checkedContacts");

Your problems come from the way you setup the getView() method and how you set the checked item in that SparseBooleanArray. I've edited your adapter's code and it should work now. The main changes are in the OnCheckedChangeListener field:
public class MyCustomAdapter extends BaseAdapter implements Filterable {
private Context mContext;
private LayoutInflater mInflater;
private SparseBooleanArray mSparseBooleanArray;
// from where do you get the data?
private ArrayList<Map<String, String>> mAdapData = new ArrayList<Map<String, String>>();
private ArrayList<Map<String, String>> mOriginalData = new ArrayList<Map<String, String>>();
public MyCustomAdapter(Context mContext) {
mInflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mSparseBooleanArray = new SparseBooleanArray();
}
public ArrayList<String> getCheckedItems() {
ArrayList<String> mTempArry = new ArrayList<String>();
for (int i = 0; i < mAdapData.size(); i++) {
if (mSparseBooleanArray.get(i)) {
Map<String, String> map = (Map<String, String>) mAdapData
.get(i);
final String numbr = map.get("Phone");
mTempArry.add(numbr);
}
}
return mTempArry;
}

I have also implemented filter List View in my application. For that, I just need a snippet of code. Check it, if it helps.
editText.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
}
public void afterTextChanged(Editable arg0) {
sendToList.this.adapter.getFilter().filter(arg0);
}
});
in the getView() method , you didn't update the UI to have the values of the filtered results .
so it returned views with old results .
just before return paramView , update the view's data to what you have in the filtered results , and remove it from the preparation of the viewHolder , since this is called only a few times .
EDIT:
here's my correction of the code . i think it will fix it:
#Override
public View getView(final int paramInt, View paramView, ViewGroup paramViewGroup) {
ViewHolder viewHolder;
if (paramView == null) {
viewHolder = new ViewHolder();
paramView = mInflater.inflate(R.layout.multiplecontactview, null);
viewHolder.tvName = (TextView) paramView.findViewById(R.id.txtContactName);
viewHolder.tvNumber = (TextView) paramView.findViewById(R.id.txtContactNumber);
viewHolder.cb = (CheckBox) paramView.findViewById(R.id.checkBox1);
viewHolder.tvName.setTextColor(Color.BLACK);
viewHolder.tvNumber.setTextColor(Color.BLACK);
paramView.setTag(viewHolder);
viewHolder.cb.setOnCheckedChangeListener(mCheckedChangeListener);
} else {
viewHolder = (ViewHolder) paramView.getTag();
}
viewHolder.cb.setTag(paramInt);
viewHolder.cb.setChecked(mSparseBooleanArray.get(paramInt));
Map<String, String> map = (Map<String, String>) mAdapData.get(paramInt);
final String name = map.get("Name").toString();
Log.e("Name", name);
final String numbr = map.get("Phone").toString();
Log.e("Number", numbr);
viewHolder.tvName.setText(name);
viewHolder.tvNumber.setText(numbr);
return paramView;
}
EDIT:
here's a sample of how i handled the filtering :
#Override
public Filter getFilter()
{
final Filter filter=new Filter()
{
#Override
protected FilterResults performFiltering(final CharSequence constraint)
{
_lastFilterConstraint=constraint;
if(TextUtils.isEmpty(constraint))
return null;
final String constraintToCheck=constraint.toString().toLowerCase(Locale.getDefault());
final FilterResults results=new FilterResults();
// <- here i do the filtering itself and later put the results into "results"
results.values=values;
results.count=values.size();
return results;
}
#SuppressWarnings("unchecked")
#Override
protected void publishResults(final CharSequence constraint,final FilterResults results)
{
_filteredItems==null ? null : (ArrayList<Item>)results.values;
notifyDataSetChanged();
}
};
return filter;
}
#Override
public int getCount()
{
if(_filteredItems!=null)
return _filteredItems.size();
return _originalItems.size();
}
#Override
public Item getItem(final int position)
{
if(_filteredItems!=null)
{
if(position<_filteredItems.size())
return _filteredItems.get(position);
return null;
}
if(position<_originalItems.size())
return _originalItems.get(position);
return null;
}
#Override
public View getView(final int position,final View convertView,final ViewGroup parent)
{
final View inflatedView;
final ViewHolder viewHolder;
if(convertView==null)
{
//<- here i inflate the view into the inflatedView
}
else
{
inflaterView=convertView;
viewHolder=(ViewHolder)inflaterView.getTag();
}
// <- here i use getItem and update the view according to its data .
return inflaterView;
}
Hi i am new to android.
1) I have a listview with names and checkboxes. I want to have a search function on this list where the user can search for a specific name.
2) I want the user to be able to select all the names in the listview with one click. When the user press on the selectAll button all the checkboxes should be checked.
I am a total beginner and totally confused.
Thanks

I am trying to restore the previous state of my Checkboxes. I have nearly 20 checkbox in my Activity and what i want is when i restart my app, all the checkbox should be checked if it was checked before exiting the app. As i am using a custom adapter so i found it very difficult to achieve.
Here is my adapter's code -
public class IconAdapter extends BaseAdapter
{
private Activity activity;
private Object[] data;
private ArrayList<HashMap<String,String>> listItems;
public static LayoutInflater inflater = null;
private PackageManager pm;
public ArrayList<Boolean> itemChecked = null;
public ArrayList<String> itemSelected = new ArrayList<String>();
public ArrayList<CheckBox> ctv = new ArrayList<CheckBox>();
//TextView textView;
CheckBox cb;
//ImageView imageView;
public CompleteTaskManager ctm = new CompleteTaskManager();
public IconAdapter(Activity a, ArrayList<HashMap<String,String>> items)
{
activity = a;
listItems = items;
data = items.toArray();
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
pm = a.getPackageManager();
if(itemChecked==null){
itemChecked = new ArrayList<Boolean>();
for(int i = 0; i < items.size(); i++)
{
itemChecked.add(i,false);
}}
for(int i = 0; i < items.size(); i++)
{
itemSelected.add(i," ");
}
for(int i = 0; i < items.size(); i++)
{
cb = new CheckBox(a);
ctv.add(i,cb);
}
}
public int getCount() {
return listItems.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public static class ViewHolder{
public TextView textView;
public ImageView imageView;
public CheckBox checkBox;
}
public View getView(final int position, View convertView, ViewGroup parent)
{
View row = convertView;
final ViewHolder holder;
if(convertView==null)
{
row = inflater.inflate(R.layout.item, parent, false);
holder = new ViewHolder();
holder.textView = (TextView)row.findViewById(R.id.text1);
holder.checkBox = (CheckBox)row.findViewById(R.id.check); holder.checkBox.setChecked(itemChecked.get(position));
holder.imageView = (ImageView)row.findViewById(R.id.image);
row.setTag(holder);
}
else
{
holder = (ViewHolder)row.getTag();
}
String s = data[position].toString();
String[] tokens = s.split(",");
String[] mToken = tokens[0].split("=");
String taskName = mToken[1];
holder.textView.setText(taskName);
String[] mTokens = tokens[1].split("=");
final String pkgName = mTokens[1].substring(0, (mTokens[1].length() - 1));
holder.checkBox.setTag(position);
//this is how i am trying to restore the checked checkboxes.
**for(int i = 0; i < itemSelected.size(); i++)
{
if(itemSelected.contains(pkgName))
{
holder.checkBox.setChecked(true);
}
}**
ctv.set(position,holder.checkBox);
holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
public void onCheckedChanged(CompoundButton button, boolean b) {
Integer posClicked = (Integer)button.getTag();
if(b)
{
itemChecked.set(posClicked, true);
itemSelected.set(posClicked, pkgName);
}
else
{
itemChecked.set(posClicked,false);
itemSelected.set(posClicked, " ");
}
}
});
holder.checkBox.setChecked(itemChecked.get(position));
try{
Drawable icon = pm.getApplicationIcon(pkgName);
holder.imageView.setImageDrawable(icon);
}
catch (PackageManager.NameNotFoundException ne)
{
}
row.setId(position);
return row;
}
public boolean isChecked(int position)
{
return itemChecked.get(position);
}
public String getPkgName(int position)
{
return itemSelected.get(position);
}
public void removeItem(int position)
{
listItems.remove(position);
}
}
and here is code in which i am trying to restore my pkgNames. I picked pkgName because i have noticed position could be shuffled as my list is dynamic but pkgName related to each item will stay same.
#Override
public void onPause()
{
super.onPause();
save(notes.itemSelected);
}
#Override
public void onResume()
{
super.onResume();
ArrayList<String> checkOld = load();
for (int i = 0 ; i < checkOld.size(); i++)
{
notes.itemSelected = checkOld;
}
}
#Override
public void onRestart()
{
super.onRestart();
ArrayList<String> checkOld = load();
for (int i = 0 ; i < checkOld.size(); i++)
{
notes.itemSelected = checkOld;
}
}
private void save(final ArrayList<String> isChecked) {
SharedPreferences sharedPreferences = getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
for(Integer i = 0; i < isChecked.size(); i++)
{
editor.putString(i.toString(), isChecked.get(i));
}
editor.commit();
}
private ArrayList<String> load() {
SharedPreferences sharedPreferences = getPreferences(Context.MODE_PRIVATE);
ArrayList<String> reChecked = new ArrayList<String>();
for(Integer i = 0; i < notes.getCount(); i++)
{
reChecked.add(i, sharedPreferences.getString(i.toString(), " "));
}
return reChecked;
}
}
Please Please HELP!!!!
