How to access arraylist of arraylist in adapters

Hi i am making android application. I am using json parsing in my application. first of all this is my json response
{
"Data": {
"headerText": "Revolution",
"productStartingPrice": "$38.78",
"sizeList": [
{
"textUpper": "Revolution for (Pink)",
"textLower": "$38.78",
"packList": [
{
"textUpper": "3 DOSES",
"textLower": "$38.78",
}
{
"textUpper": "6 DOSES",
"textLower": "$71.60",
}
]
},
{
"textUpper": "Revolution for (Blue)",
"textLower": "$46.92",
"packList": [
{
"textUpper": "3 DOSES",
"textLower": "$46.92",
}
{
"textUpper": "6 DOSES",
"textLower": "$79.56",
}
{
"textUpper": "12 DOSES",
"textLower": "$137.27",
}
]
}
]
},
"Status": 1,
"Message": "",
"UserMessage": ""
}
Now I am using custom alert dialog to load sizelist array and another dailog for packlist array. Now what i want is when user select (Pink) from sizelist then in second dailog i want to display 3 doses and 6 doses from packlist and when user select (Blue) i want to display 3 doses, 6 doses ,12 doses. Right now i am getting only last two items of (Blue) 6 doses ,12 doses. can any one help me to solve this?

Change your showDialogpacks like this.On click of the first dialog pass the position that is been clicked and then inside that pass only the item
inside sizelists for particular position.
private void showDialogpacks(int position){
dialogfpacks = new Dialog(getActivity());
View view = getActivity().getLayoutInflater().inflate(R.layout.dialog_main_packs, null);
ListView lv = (ListView) view.findViewById(R.id.custom_list_packs);
Button close_btn = (Button) view.findViewById(R.id.close_btn_packlist);
adapterpacks = new CustomListAdaptertwo(getActivity(), sizelists.get(position).getPacklistmodel());
lv.setAdapter(adapterpacks);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
dialogfpacks.setContentView(view);
dialogfpacks.show();
}
Also change the second adapter list type to ProductLandingPackListModel.
public CustomListAdaptertwo(Context context,List<ProductLandingPackListModel> adaptersizelist) {
this.context = context;
this.adaptersizelist=adaptersizelist;
inflater = LayoutInflater.from(context);
}
And in the inside of the CustomAdapdtertwo getView method
final ProductLandingPackListModel model = adaptersizelist.get(position);
holder.txtproname.setText(model.getPackList_textUpper());
holder.txtproprice.setText(model.getPackList_textLower());

Hi Chris based upon size selection set packlist...update pack list of every size user selects

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;
}

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.

Multiple checkboxes get (de)selected when one is checked in Gridview - Android

So I have a Gridview where each grid item consists of an ImageView and a Checkbox. It calls Image Adapter to populate the grid dynamically. Now, when I select one checkbox, lets say number 5, another checkbox like number 12 gets selected automatically. Similar for deselection. I cannot figure out why this is happening. Any help will be appreciated. Thanks!

Explaination:
In checkboxListviewAdapter.java
1) Let's say you have 10 checkbox in your listview. So, create a boolean[] to hold your all checkbox's boolean value.
private boolean[] booleanList = new boolean[10];
2) In your constructor, use for loop to set booleanList's as false.
public checkboxListviewAdapter (Context context, String[] subjectList ) {
//this.context = context;
//this.subjectList = subjectList;
//selectedList = new Boolean[subjectList.length];
//inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i < selectedList.length; i++){
selectedList[i] = false;
}
}
3) Now, in your getView, add the below code to get the boolean value from the booleanList and set the boolean value each time we scroll the listview.
holder.cb.setChecked(selectedList[position]);
4) Finally, to add a listener to your checkbox, use OnClickListener.
holder.cb.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(selectedList[position] == false) {
selectedList[position] = true;
} else {
selectedList[position] = false;
}
}
});
5) run the code and check the result.

You are saving the state of the checkbox in thumbnailsselection when it's clicked, but you don't use that state in getView() to set up the initial appearance of the checkbox. So you are probably getting random checkbox states from recycled views.
Call holder.checkbox.setState() with the state from thumbnailsselection to create the GridView item with the correct checkbox appearance.

CheckedTextView ListView with Headers - sort

I know this is not the first question about this topic with CheckBoxes and ListViews, but I don't know what to do..
I have a ListView with CheckedTextView and TextView and if I scroll some other's will get checked...
The views get resorted too and the enable/disable part (with the SharedPref) also don't work...

Android ListView Headers
So there is my code:
ActivtyMain.java
public class ActivityMain extends NavigationDrawerActivity{
#Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
super.onCreate(savedInstanceState);
context=this;
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
character_header_id.add(0);
character_header_id.add(character_original.size()+1);
character_header_id.add(character_original.size()+character_extension1.size()+2);
character_header_id.add(character_original.size()+character_extension1.size()+character_extension2.size()+3);
items.add(new CharacterHeader(getString(R.string.character_original)));
for(character key:character_original) {
String value=character_translation.get(key);
//System.out.println(value);
items.add(new CharacterListItem(value));
}
items.add(new CharacterHeader(getString(R.string.character_extension1)));
for(character key:character_extension1) {
String value=character_translation.get(key);
items.add(new CharacterListItem(value));
}
items.add(new CharacterHeader(getString(R.string.character_extension2)));
for(character key:character_extension2) {
String value=character_translation.get(key);
items.add(new CharacterListItem(value));
}
items.add(new CharacterHeader(getString(R.string.character_extension3)));
for(character key:character_extension3) {
String value=character_translation.get(key);
items.add(new CharacterListItem(value));
}
lv_charactere=((ListView) findViewById(R.id.character_list));
lv_charactere.setAdapter(new CharacterArrayAdapter(this, items));
//TODO check/unceck scroll problem

I think I posted all important code parts, if something is missing, please let me know
I don't know what to do..

getView
ViewHolder viewHolder = new ViewHolder();
if (convertView == null) {
if(items.get(position).getClass().equals(CharacterListItem.class)) {
convertView = mInflater.inflate(R.layout.character_list_item, null);
viewHolder.checkedtextview = (CheckedTextView) convertView.findViewById(R.id.listitem_character);
viewHolder.checkedtextview.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
onClickListener(v);
}
});
convertView.setTag(viewHolder);
convertView.setTag(R.id.listitem_character, viewHolder.checkedtextview);
}else{
convertView = mInflater.inflate(R.layout.character_header, null);
viewHolder.textview=(TextView) convertView.findViewById(R.id.listheader_character);
convertView.setTag(viewHolder);
convertView.setTag(R.id.listheader_menu, viewHolder.textview);
}
}else{
viewHolder = (ViewHolder) convertView.getTag();
}
if(viewHolder.checkedtextview!=null) {
viewHolder.checkedtextview.setTag(position); // This line is important.
viewHolder.checkedtextview.setText(items.get(position).getText());;
loadSettings(viewHolder);
return convertView;
}else{
return getItem(position).getView(mInflater, convertView);
}
important change (I think so):
only on the second part to set the position
