listview is not refreshing values after deleting row with checkbox value = true

Good day,
I'm doing a listview, baseadapter with checkbox that is able to delete multiple selected rows.
here is my onCreate :
ArrayList<Memos> list;
list = new ArrayList<Memos>();
list.add(new Memos(1, "s", "s"));
list.add(new Memos(2, "x", "aaa"));
list.add(new Memos(3, "v", "aesf"));
final ListView lv = (ListView) findViewById(R.id.myList);
lv.setAdapter(new MemoListAdapter(list, this));
deletebutton
#Override
public void onClick(View v) {
MemoListAdapter myAdapter = (MemoListAdapter)lv.getAdapter();
myAdapter.remove();
}
then here is my complete baseadapter :
public class MemoListAdapter extends BaseAdapter {
private List<Memos> listComment;
private Context context;
private LayoutInflater inflater = null;
private ArrayList<Memos> deleteMemos;
public MemoListAdapter(List<Memos> listComment, Context context) {
super();
this.listComment = listComment;
this.context = context;
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
deleteMemos = new ArrayList<Memos>();
}
#Override
public int getCount() {
return listComment.size();
}
#Override
public Memos getItem(int position) {
return listComment.get(position);
}
#Override
public long getItemId(int arg0) {
return 0;
}
#Override
public int getViewTypeCount() {
return getCount();
}
#Override
public int getItemViewType(int position) {
return position;
}
public class ViewHolder
{
TextView body;
TextView date;
CheckBox checkBox;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.list_view, null);
holder = new ViewHolder();
holder.body = (TextView) convertView.findViewById(R.id.big_text);
holder.date = (TextView) convertView.findViewById(R.id.small_text);
holder.checkBox = (CheckBox) convertView.findViewById(R.id.checkbox);
holder.body.setText(listComment.get(position).getMessageBody());
holder.date.setText(listComment.get(position).getMessageDate());
holder.checkBox.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//is chkIos checked?
if(listComment.get(position).isCheckbox()) {
holder.checkBox.setChecked(false);
deleteMemos.remove(listComment.get(position));
}
else {
// Do invisible or gone stuff here
holder.checkBox.setChecked(true);
deleteMemos.add(listComment.get(position));
}
}
});
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
return convertView;
}
public void remove() {
for(Memos memo : deleteMemos) {
listComment.remove(memo);
}
this.notifyDataSetChanged();
}
}
after selecting rows to delete (4 rows)
the list adjusted but the contents and the check value of the checkbox is still the same.
I am wondering what part of the notifyDataSetChanged is wrong.
Thanks in advance!

Your views are reused that's why it happen . Try adding below codes into your getView()
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.list_view, null);
holder = new ViewHolder();
holder.body = (TextView) convertView.findViewById(R.id.big_text);
holder.date = (TextView) convertView.findViewById(R.id.small_text);
holder.checkBox = (CheckBox) convertView.findViewById(R.id.checkbox);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
if(listComment.get(position).isCheckbox()) {
holder.checkBox.setChecked(true);
}else {
holder.checkBox.setChecked(false);
}
holder.body.setText(listComment.get(position).getMessageBody());
holder.date.setText(listComment.get(position).getMessageDate());
holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
listComment.get(position).setIsCheckbox(isChecked);
if (isChecked){
deleteMemos.add(listComment.get(position));
}else{
deleteMemos.remove(listComment.get(position));
}
}
});
return convertView;
}

Try this way. this worked for me
public class CustomAdapter extends BaseAdapter {
private final LayoutInflater inflater;
private final Context context;
private List<ModelPooja> listData;
public CustomAdapter(Context mainActivity, List<ModelPooja> listData) {
context = mainActivity;
this.listData = listData;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return listData.size();
}
#Override
public Object getItem(int position) {
return listData.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.list_item_poojaselection, null);
holder.tv = (TextView) convertView.findViewById(R.id.list_item_poojaname);
holder.checks = (CheckBox) convertView.findViewById(R.id.list_item_poojacheck);
convertView.setTag(holder);
}else {
holder = (ViewHolder) convertView.getTag();
}
holder.checks.setOnCheckedChangeListener(null);
holder.checks.setFocusable(false);
if (listData.get(position).isselected) {
holder.checks.setChecked(true);
} else {
holder.checks.setChecked(false);
}
holder.checks.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

} else {

Toast.makeText(context, "Max limit reached", Toast.LENGTH_SHORT).show();
}
} else {
if (b) {

} else {
listData.get(position).isselected = false;
}
}
}
});
holder.tv.setText(listData.get(position).getPOOJA_LISTING_NAME());
return convertView;
}
public boolean checkMaxLimit() {
int countermax = 0;
for(ModelPooja item : listData){
if(item.isselected){

}
}
return countermax >= 5;
}
public class ViewHolder {

}
}
For Recyclerview try this way
http://android-pratap.blogspot.in/2015/01/recyclerview-with-checkbox-example.html

#Override
public int getViewTypeCount() {
return getCount();
}
#Override
public int getItemViewType(int position) {
return position;
}
Add two functions into your "Adapter" class
Note: If you use RecycleView, just add getItemViewType(int position).

Problem is in your getView() method. You set OnCheckedChangeListener and after that you set checkbox to true or false which fires callback in that listener. You should set checkbox check state first and after that set OnCheckedChangeListener.
Also, that boolean checked[] field is useless, so I simplified your code a little:
public class CustomAdapter extends BaseAdapter {
private final LayoutInflater inflater;
private final Context context;
private List<ModelPooja> listData;
public CustomAdapter(Context mainActivity, List<ModelPooja> listData) {
context = mainActivity;
this.listData = listData;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return listData.size();
}
#Override
public Object getItem(int position) {
return listData.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.list_item_poojaselection, null);
holder.tv = (TextView) convertView.findViewById(R.id.list_item_poojaname);
holder.checks = (CheckBox) convertView.findViewById(R.id.list_item_poojacheck);
convertView.setTag(holder);
}else {
holder = (ViewHolder) convertView.getTag();
}
holder.checks.setOnCheckedChangeListener(null);
holder.checks.setFocusable(false);
if (listData.get(position).isselected) {
holder.checks.setChecked(true);
} else {
holder.checks.setChecked(false);
}
holder.checks.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton cb, boolean b) {
if (checkMaxLimit()) {
if (listData.get(position).isselected && b) {
holder.checks.setChecked(false);
listData.get(position).isselected = false;
} else {
holder.checks.setChecked(false);
listData.get(position).isselected = false;
Toast.makeText(context, "Max limit reached", Toast.LENGTH_SHORT).show();
}
} else {
if (b) {
listData.get(position).isselected = true;
} else {
listData.get(position).isselected = false;
}
}
}
});
holder.tv.setText(listData.get(position).getPOOJA_LISTING_NAME());
return convertView;
}
public boolean checkMaxLimit() {
int countermax = 0;
for(ModelPooja item : listData){
if(item.isselected){
countermax++;
}
}
return countermax >= 5;
}
public class ViewHolder {
TextView tv;
public CheckBox checks;
}
}

Make a Boolean array initially with false value in adapter.If user checks the array make array's position true. On uncheck make it false. Always set the checkbox value from that boolean array.

This is because when you scroll your listview from upper or lower side of phone, all items of listview are regenerated and they are set to default value.
To avoid this make a model class which holds the current value of checkbox(true or false) and set the value of checkbox in adapter by calling getter method from that model instance.
For example:
model.java
public class AddressModel {
private boolean isChecked;
private String address;
private int alAddressDelete;
public AddressModel(){
}
public AddressModel(boolean isChecked, String address, int alAddressDelete) {
this.isChecked = isChecked;
this.address = address;
this.alAddressDelete = alAddressDelete;
}
public boolean getIsChecked() {
return isChecked;
}
public void setIsChecked(boolean isChecked) {
this.isChecked = isChecked;
}
}
In your Adapter class set the value of checkbox by calling setIsChecked(boolean isChecked) in the setOnCheckedChangeListener().
call getIsChecked() where you are setting value of your checkboxes.

Call setOnCheckedChangeListener() first, then call setChecked(), otherwise the setChecked() will trigger the previous ViewHolder object's setOnCheckedChangeListener().

Android : ImageView with checkbox in grid-view

I am trying to delete images with Checkbook.
I have done to delete the selected multiple images which is checked from grid-view on button click event. But the check-boxes are appearing as they are in the grid-view .
How can I remove the check-boxes also with images?
Thanks in advanced.
Here is my check-box code in getView() method in Android
class GridView_Adapter extends BaseAdapter {
private LayoutInflater mInflater;
SparseBooleanArray mSparseBooleanArray;
public GridView_Adapter() {

mSparseBooleanArray = new SparseBooleanArray();
}
public ArrayList<String> getCheckedItems() {
ArrayList<String> mTempArry = new ArrayList<String>();
for(int i=0;i<fileName.size();i++) {
if(mSparseBooleanArray.get(i)) {
mTempArry.add(fileName.get(i));
}}
return mTempArry;
}
public int getCount() {
return fileName.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {

how to limit checkbox selection in listview?

friends,
i want to limit checkbox selection in android listivew to for example only 3 checkboxes should be selected otherwise it should give error message.
user can select any three checkboxes from the list
any one guide me how to achieve this? here is my adapter
public class AdapterContacts extends BaseAdapter {
private LayoutInflater mInflater;
public Context context;
public static List<myContacts> contacts;
public AdapterContacts(Context context,List<myContacts> list) {
mInflater = LayoutInflater.from(context);
this.context = context;
contacts= list;
}
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_contacts, null);
holder = new ViewHolder();
holder.contactName = (TextView) convertView.findViewById(R.id.contactName);
holder.contactNumber = (TextView) convertView.findViewById(R.id.contactNumber);
holder.checkBox = (CheckBox) convertView.findViewById(R.id.checkBox);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
myContacts contact = getItem(position);
holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton checkboxView, boolean isChecked) {
myContacts c = (myContacts) checkboxView.getTag();
c.setSelected(isChecked);
// to put that check of selection limit with error
}
});
holder.checkBox.setTag(contact);
holder.checkBox.setChecked(contact.isSelected());
holder.contactName.setText(contact.getContactName());
holder.contactNumber.setText(contact.getPhoneNumber());
return convertView;
}
#Override
public int getCount() {
return contacts.size();
}
#Override
public myContacts getItem(int position) {
return contacts.get(position);
}
#Override
public long getItemId(int arg0) {
return 0;
}
class ViewHolder {
TextView contactName;
TextView contactNumber;
CheckBox checkBox;
}
}
any help would be appreciated.

finally i solved this issue :) where as globalInc is global variable with default value 0
holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
#Override
public void onCheckedChanged(CompoundButton checkboxView, boolean isChecked)
{
myContacts c = (myContacts) checkboxView.getTag();
if(isChecked)
{
globalInc++;
}
else if(!isChecked)
{
globalInc--;
}
if(globalInc >= 4)// it will allow 3 checkboxes only
{
Toast.makeText(context, "Error = " + globalInc, Toast.LENGTH_LONG).show();
checkboxView.setChecked(false);
globalInc--;
}
else
{
c.setSelected(isChecked);
}
System.out.println(" --------------- "+globalInc);
}
});

i solved the issue "after scroll listview user can also again select more than 3 check boxex" Thanks for you patience
set static int count = 0;
if (isChecked) {
count++;
} else if (!isChecked) {
count--;
}
if (count >= 4) {
buttonView.setChecked(false);
count--;
} else {
int getPosition = (Integer) buttonView.getTag();
contact.get(getPosition).setSelected(buttonView.isChecked());
}
And Most imprtant is that add count=0 in else and viewHolder.chkContact.setTag(position) after else;
if(convertView == null){
}else
{
viewHolder = (ViewHolder) convertView.getTag();
count=0;
}
viewHolder.chkContact.setTag(position);
`

Take a static int count variable and increment it using these condition
holder.checkBox.isChecked() if it is true then increment in the count
then check count>3 then show popup to user
I hope this is Help.

viewHolder.checkbox.setTag(position); // This line is important.
viewHolder.friendName.setText(list.get(position).getname());

Try this:
public class AccountListAdapter extends BaseAdapter {
#SuppressWarnings("unused")
private final static String TAG = AccountListAdapter.class.getSimpleName();
private Context context;
private List<Account> rowItems;
private int selectedItemCounter = 0;
private final int limit;
public AccountListAdapter(Context context, List<Account> items, int limit) {
this.context = context;
this.rowItems = items;
this.limit = limit;
}
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
final Account rowItem = (Account) getItem(position);
convertView = mInflater.inflate(R.layout.account_selection_item, null);
TextView tv = (TextView) convertView.findViewById(R.id.textView);
ToggleButton tb = (ToggleButton) convertView
.findViewById(R.id.toggleButton);
tb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if (isChecked && !rowItem.isSelected()) {
if (selectedItemCounter >= limit) {
Toast.makeText(context,
"can't be more" + selectedItemCounter,
Toast.LENGTH_SHORT).show();
buttonView.setChecked(false);
return;
}
rowItem.setSelected(true);
selectedItemCounter++;
} else if (!isChecked && rowItem.isSelected()) {
rowItem.setSelected(false);
selectedItemCounter--;
}
}
});
tv.setText(rowItem.getDevId());
tb.setChecked(rowItem.isSelected());
return convertView;
}
#Override
public int getCount() {
return rowItems.size();
}
#Override
public Object getItem(int position) {
return rowItems.get(position);
}
#Override
public long getItemId(int position) {
return rowItems.indexOf(getItem(position));
}
}
tried to improve my code with ViewHolder pattern but failed.
if anyone have better idea, please let me know.
