I have implemented a Names with a check box in a List, Here my aim is to check the check box and get the respective name. Here i have written code in adapter and in activity class but i am not getting any value and it is not showing any errors.
Here my adapter code..
public Add_member_adapter(Context a, ArrayList<ItemsModel> d) {
context = a;
data = d;
checkedHolder = new boolean[data.size()];
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
if (data.size() <= 0)
return 1;
return data.size();
}
public final Object getItem(int position) {
return data.get(position);
}
public final long getItemId(int position) {
return position;
}
public static class ViewHolder {
public TextView Name, UserId_Fk;
CheckBox chkbox;
}
public View getView(final int position, View convertView, ViewGroup parent) {
Log.d("getview:", "position=" + position);
vi = convertView;
final ViewHolder holder;
if (convertView == null) {
vi = inflater.inflate(R.layout.add_members_list_item, null);
holder = new ViewHolder();
holder.Name = (TextView) vi.findViewById(R.id.Name);
holder.UserId_Fk = (TextView) vi.findViewById(R.id.CusId_Fk);
holder.chkbox = (CheckBox) vi.findViewById(R.id.chkbox);
vi.setTag(holder);
} else {
holder = (ViewHolder) vi.getTag();
}
if (data.size() <= 0) {
vi.setVisibility(View.GONE);
} else {
tempValues = null;
tempValues = (ItemsModel) data.get(position);
holder.Name.setText(tempValues.getItemName().toString());
Log.i(TAG, "Name " + tempValues.getItemName().toString());
holder.UserId_Fk.setText(tempValues.getUserId_Fk().toString());
holder.chkbox.setChecked(false);
holder.chkbox.setChecked(checkedHolder[position]);
Log.i(TAG, "Position " + checkedHolder[position]);
holder.chkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
checkedHolder[position] = isChecked;
Log.i(TAG, "Position " + checkedHolder[position]);
}
});
}
return vi;
}
In Activity...
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// String Name = list.getItemAtPosition(position).toString();
// CheckBox cb = (CheckBox) view.findViewById(R.id.chkbox);
// TextView tv = (TextView) view.findViewById(R.id.Name);
for (int i = 0; i < adapter.getCount(); i++) {
if (adapter.checkedHolder[i]) {
// get all name values that checked by user
Name = ((TextView) findViewById(R.id.Name)).getText()
.toString();
Log.i(TAG, "Name " + Name);
}
}
}
});
change your setOnItemClikListener as below
for (int i = 0; i < adapter.getCount(); i++) {
if (adapter.checkedHolder[i]) {
// get all name values that checked by user
Name = data.get(i).getItemName().toString();
Log.i(TAG, "Name " + Name);
}
in getView relpace holder.chkbox.setChecked(false); with below line ;
holder.chkbox.setOnCheckedChangeListener(null);

listview row having multiple checkboxex, when i checked the checkboxex then if i scroll the listview, its automatically unchecked the checkboxes. how can fix this issue. here is my getView method
public View getView(final int position, View convertView, ViewGroup parent) {

questionRadioHolder = (QuestionRadioHolder) convertView.getTag();
}
List<String> arrayList = rowItem.getArrayList();

}
});
} else if (type == TYPE2) {
if (convertView == null) {

if (arraylist2 == null) {
arraylist2 = list;
}

}
System.out.println(aMap1.get(id));
}
});
questionCheckboxHolder.relativeLayout.addView(checkBox);
}
}
return convertView;
}
If i scroll the listview, its automatically unchecked the checkbox, how can checked the checkbox.
Try this way this worked for me
public class CustomAdapter extends BaseAdapter {

public CustomAdapter(Context mainActivity, List<ModelCls> listData) {

inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override

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);

}
}
}
});
holder.tv.setText(listData.get(position).getLISTING_NAME());
return convertView;

public boolean checkMaxLimit() {
int countermax = 0;
for(ModelCls item : listData){

and if you want to recyclerview try this
http://android-pratap.blogspot.in/2015/01/recyclerview-with-checkbox-example.html
Save your check list in ArrayList<Boolean>, and load it in getView():
ArrayList<Boolean> listCheck;
public YourAdapter(Context context, int resource, ArrayList<T> list) {
super(context, resource, list);
listCheck = new ArrayList<Boolean>;
for (int i = 0; i < list.size(); i++) {
listCheck.add(false); // init listCheck
}
}
public View getView(final int position, View convertView, ViewGroup parent) {
yourCheckBox.setChecked(listCheck.get(position)); // set checkbox
yourCheckBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
listCheck.set(position, isChecked); // update listChecked
}
}
}
If you checked on checkbox, you can save it into a HashMap(key:position, value:true/false), and in method getView() you can distinguish which is checked or unchecked, then make the checkbox show its state.
Try Using a model class or array to keep the values of checkbox and update it on onclick if that checkbox may solve your issue I think.
holder.checkBox.setChecked(mCheckList.get(position));
holder.checkBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mCheckList.set(position, !mCheckList.get(position));
notifyDataSetChanged();
}
});
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.
I'm trying to do a listview like some android explorer, which if you make a long click on an item a checkbox appear in all rows.
I have the next Adapter, and the next code in my fragment, it do it, but for some reason, one row is not changing.

I'm trying to make a listView that display a question witt a variable numbers of checkBoxs. I'm using a class that extends BaseAdapter. My problem come when the list need to scroll and then get rows repeated. I know where is my error but I cant get a solution. I need to extract part of the code out of the metod getView, like I did in title of the question but I cant make for the rest, Please help.
