Android Listview ViewHolder different items react together

I'm working on a ListView which use an Adapter and ViewHolder component in aim to ensure stability of items but I'm facing an unexpected behavior.
At first I need to explain that my items aren't static : each item is a row with a checkbox and when the box is checked a form appears below to ask user to give more informations.
But at the moment when user check the box and enter some text in the form, another item react the same way :
checkbox checked
the same text in the form
The unwanted reacting item is not drawn at the same time ( both items aren't visible together, a scroll is needed to see one or the other)
It's not accurate but my activity setting windowSoftInputMode is adjustNothing
Thanks for any answer!
Great day

the code is quite complex for the checkbox due to the show/hide form but does it may produce this unwanted listview items behavior?
Thanks

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 :
http://pastebin.com/mTEiXryf
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 Position on button click

I am android developer, I have a custom listview with a checkbox. This layput also contain a delete button. I want when I click on cheakbox all the item in a particular row is selected and on click of delete it is deleted.
The problem is when I click on delete button I get a list of +1 row value.
Initially I already define :
int position=0;
btmsgdelete.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("request send for message delete");
for(Message msg:almsg) {
if(msg.isSelected()) {
CheckBox chk = (CheckBox)findViewById(R.id.checkBox1);
System.out.println("msg is selected");
msgid=almsg.get(position).getEmpid();
System.out.println(msgid);
empname=almsg.get(position).getEmpname();
System.out.println(empname);
msgheader=almsg.get(position).getHeader();
System.out.println(msgheader);
}
}

Try this sample code
public class MainActivity extends Activity {

searchResults.remove(i);
}
}
lst.setAdapter(new Adapter(MainActivity.this, textViewResourceId,

});
System.out.println("size " + searchResults.size());

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?

listview with edittext ,checkbox and textView in android

i have created a listview with checkbox,edittext and textview.
data is populated in listview with sql server. but i am not being able to use onCheckedChangedListener on checkbox. so that on clicking the checkbox corresponding data of textview and edittext is not being saved..
i know i am doing mistake somewhere in my adapter class..
How to save data and what logic should i use in onCheckedChangedListener in my adapter class?

for saving data of textview and EditText what logic should i use and where in Adapter clss i should write it..

May not be a solution, but a suggestion.
Prefer not to declare your Listeners inside an 'if' condition. What I meant is,
IF convertview == null
find views
ELSE
getTag()
Rest of the codes

Is it that your checkbox event is not firing?
I use setOnClickListener for my Checkbox events:
CheckBox checkbox = (CheckBox)view.findViewById(R.id.item_checkbox);
checkbox.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Mark model as selected/not selected
if (model.isSelected())
model.markAsNotSelected();
else
model.markAsSelected();
}
});

I know it's an old question, but if anyone else is facing same problem, replace the Adapter class with the following code.
public class MyAdapter extends ArrayAdapter<Model> implements TextWatcher{
private final List<Model> list;
private final Context context;
public MyAdapter(Context context, List<Model> list)
{
super(context, R.layout.row, list);
this.context = context;
this.list = list;
}
static class ViewHolder
{
protected TextView text;
protected CheckBox checkbox;
protected EditText scores;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
ViewHolder viewHolder = null;
if (convertView == null){
LayoutInflater inflator = LayoutInflater.from(context);
convertView = inflator.inflate(R.layout.row, null);
viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.label);
viewHolder.scores=(EditText) view.findViewById(R.id.txtAddress);
viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
viewHolder.checkbox.setTag(list.get(position));
viewHolder.scores.setTag(list.get(position));
convertView.setTag(viewHolder);
}
else
{
convertView = (ViewHolder) convertView.getTag();
}
viewHolder.scores.addTextChangedListener(this)
viewHolder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
Model element = (Model) viewHolder.checkbox.getTag();
element.setSelected(buttonView.isChecked());
}
});
ViewHolder holder = (ViewHolder) view.getTag();
holder.text.setText(list.get(position).getName());
holder.scores.setText(list.get(position).getScore());
holder.checkbox.setChecked(list.get(position).isSelected());
return view;
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
Model element=(Model)viewHolder.scores.getTag();
element.setScore(s.toString());
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,int after)
{
}
#Override
public void afterTextChanged(Editable s)
{
}
});
}
