Listview with checkbox bug android

I have custom list view with checkbox, when I executed in my small mobile phone, if list view already had 5 items, then when I checked item 1, then item 5 will be checked also, if I checked item 5 then item 1 will be checked also, it happened with item (2-6,3-7,4-8, etc).
But if I had 4 items in my listview, it wont be happened. Here my listview adapter :

Could you help me to solve my bug ? Thanks in advance

I suggest you to use Recyclerview
public class CardViewDataAdapter extends
RecyclerView.Adapter<CardViewDataAdapter.ViewHolder> {
private List<Student> stList;
public CardViewDataAdapter(List<Student> students) {
this.stList = students;
}
// Create new views
#Override
public CardViewDataAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
View itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(
R.layout.cardview_row, null);
// create ViewHolder
ViewHolder viewHolder = new ViewHolder(itemLayoutView);
return viewHolder;
}
#Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {
final int pos = position;
viewHolder.tvName.setText(stList.get(position).getName());
viewHolder.tvEmailId.setText(stList.get(position).getEmailId());
viewHolder.chkSelected.setChecked(stList.get(position).isSelected());
viewHolder.chkSelected.setTag(stList.get(position));
viewHolder.chkSelected.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v;
Student contact = (Student) cb.getTag();
contact.setSelected(cb.isChecked());
stList.get(pos).setSelected(cb.isChecked());
Toast.makeText(
v.getContext(),
"Clicked on Checkbox: " + cb.getText() + " is "
+ cb.isChecked(), Toast.LENGTH_LONG).show();
}
});
}
// Return the size arraylist
#Override
public int getItemCount() {
return stList.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView tvName;
public TextView tvEmailId;
public CheckBox chkSelected;
public Student singlestudent;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
tvName = (TextView) itemLayoutView.findViewById(R.id.tvName);
tvEmailId = (TextView) itemLayoutView.findViewById(R.id.tvEmailId);
chkSelected = (CheckBox) itemLayoutView
.findViewById(R.id.chkSelected);
}
}
// method to access in activity after updating selection
public List<Student> getStudentist() {
return stList;
}
}
OR
If you want to use listview,then better you maintain Boolean array for checkbox,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() {
#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;
}
}

Here is solution- You had added holder.chkbox.setOnClickListener at wrong place just put it at right place. Replace your code with this code
if(convertView == null) {
convertView = myInflater.inflate(R.layout.customviewitemcashier, null);
holder = new ViewHolder();
holder.tvitemcode = (TextView) convertView.findViewById(R.id.tvitemcode);
holder.tvitemname = (TextView) convertView.findViewById(R.id.tvitemname);
holder.tvprice = (TextView) convertView.findViewById(R.id.tvprice);
holder.tvsubtotal = (TextView) convertView.findViewById(R.id.tvsubtotal);
holder.edtqty = (EditText) convertView.findViewById(R.id.edtqty);
holder.imgincrease = (TextView) convertView.findViewById(R.id.imgincrease);
holder.imgdecrease = (TextView) convertView.findViewById(R.id.imgdecrease);
holder.imgitem= (ImageView) convertView.findViewById(R.id.imgitem);
holder.chkbox = (CheckBox) convertView.findViewById(R.id.checkbox);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.chkbox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (holder.chkbox.isChecked()) {
SQLiteDatabase dbinsert = dbHelper.getWritableDatabase();
String SQLinsert = "INSERT INTO itemcheckedcontainer (`item_code`) VALUES (" +
"'" + DataProcessorResult.get(position).getItemCode() + "')";
dbinsert.execSQL(SQLinsert);
} else {
SQLiteDatabase dbdelete = dbHelper.getWritableDatabase();
String SQLdelete = "DELETE FROM itemcheckedcontainer WHERE item_code=" +
"'" + DataProcessorResult.get(position).getItemCode() + "'";
dbdelete.execSQL(SQLdelete);
}
}
});
Your problem solved.

listView checkbox scrolling bug

I have a problem with a listView consisting of check-boxes. When I scroll some items get selected automatically.
This is my code for the getView method in my custom adapter:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
convertView = inflater.inflate(R.layout.prerequisite_course, parent, false);
holder = new ViewHolder();
holder.name = (CheckBox) convertView.findViewById(R.id.course_checkbox);
convertView.setTag(holder);
holder.name.setOnClickListener( new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v ;
Course course = (Course) cb.getTag();
if (cb.isChecked())
checkBoxChecked(cb, course);
else
checkBoxNotChecked(cb, course);
}
});
}
else {
holder = (ViewHolder) convertView.getTag();
}
Course course = coursesDataManager.getCourseInPosition(position);
String currentId = COURSES_SUBJECT + " " + course.getId();
holder.name.setText(currentId);
holder.name.setTag(course);
// for the clear button:
if (!holder.name.isChecked()) {
checkBoxNotChecked(holder.name, (Course) holder.name.getTag());
}
return convertView;
}
private void checkBoxChecked(CheckBox cb, Course add) {
cb.setBackgroundColor(Color.rgb(1, 67, 121));
cb.setTextColor(Color.WHITE);
myCoursesManager.addPrerequisite(add);
}
private void checkBoxNotChecked(CheckBox cb, Course remove) {
cb.setBackgroundColor(Color.WHITE);
cb.setTextColor(Color.BLACK);
myCoursesManager.removePrerequisite(remove);
}
Also, criticism of the code would be welcomed as I'm new to android development. Thank you.

You need to maintain boolean array for checkbox,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() {
#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;
}
}

Create a Model Class for saving the checkBox status for the list items.
public class ModelClass
{
int position=null;
String item=null;
boolean selected=false;
public ModelClass(int position,String item, boolean selected) {
super();
this.position=position;
this.item=item;
this.selected = selected;
}
}
Then in your Adapter Class
private ArrayList<ModelClass> arl;
Inside your getView()
holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
arl.get(position).selected=isChecked;
}
});
holder.checkBox.setChecked(arl.get(position).selected);
And now no matter how much you scroll your checkBoxes state will be consistent(Trust me, I have used this code in my Project).

Android : Check-box issue in Grid-View

I'm trying to delete multiple selected images from Grid View.Images are deleted proper way but check box was appear as it is grid-view on Button click event.Can someone help me for solve this issue.Thanks in advance.
Here is my Code deletion
class GridView_Adapter extends BaseAdapter {

}
});
}
}

When Checked one Checkbox , Multiple checkboxes get selected?

I have a Custom adapter class, as follows.When I select one checkbox,other checkboxes also gets selected after 7-8 rows. Even if setonclicklisterner is not implement, checkboxes behaves the same. I need a proper solution. I searched a lot but not getting the solution.
How can I stop avoiding the multiple selection of checkboxes?

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.

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.
