In the following code
here is my main Activity Where i choose various product and proceed further
but when I checked multiple or one it pass 0 value;
that is in Toast I am not getting anything as below in image
public class MainActivity extends ListActivity {
ListView list;
Button btn1;
String url="";
private ArrayList <Product> allProducts = new ArrayList<Product>();
private ProductAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
btn1 = (Button) findViewById(R.id.btn);
list = getListView();
url="http://192.168.1.100/test/product.txt?id=";//+d.getInt("id");
try{
ConnectivityManager c =(ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo n =c.getActiveNetworkInfo();
if (n!= null && n.isConnected()){
Log.d("url*********",url);
new Background().execute(url);
}
}catch(Exception e){}
adapter = new ProductAdapter(this,allProducts);
setListAdapter(adapter);
getListView().setItemsCanFocus(false);
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
StringBuffer responseText = new StringBuffer();
responseText.append("The following were selected...\n");
for(int i=0;i<allProducts.size();i++){
Product product = allProducts.get(i);
if(product.isChecked()){
responseText.append("\n" + product.getProduct_name());
}
}
Toast.makeText(getApplicationContext(),
responseText, Toast.LENGTH_LONG).show();
}
});
}
Here is ProductAdapter
public class ProductAdapter extends ArrayAdapter<Product> {
ArrayList<Product> allProducts;
LayoutInflater vi;
int Resource;
Context context;
public ProductAdapter (Context context ,ArrayList<Product> objects)
{
super(context, R.layout.productrow, objects);
allProducts = objects;
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
convertView = inflater.inflate(R.layout.productrow, parent, false);
TextView name = (TextView) convertView.findViewById(R.id.price);
CheckBox cb = (CheckBox) convertView.findViewById(R.id.cb1);
int s = allProducts.get(position).getProduct_price();
name.setText(Integer.toString(s));
cb.setText(allProducts.get(position).getProduct_name());
if(allProducts.get(position).isChecked())
cb.setChecked(true);
else
cb.setChecked(false);
return convertView;
}
}
My Product.java file which is my model
public class Product {
int product_id;
private boolean checked = false ;
public boolean isChecked() {
return checked;
}
public void setChecked(boolean checked) {
this.checked = checked;
}
String product_name;
int product_price;
int product_qunatity;
int hotel_id;
public int getProduct_id() {
return product_id;
}
public void setProduct_id(int product_id) {
this.product_id = product_id;
}
public String getProduct_name() {
return product_name;
}
public void setProduct_name(String product_name) {
this.product_name = product_name;
}
public int getProduct_price() {
return product_price;
}
public void setProduct_price(int product_price) {

Ok, there is declaration of checkbox CheckBox cb = (CheckBox) convertView.findViewById(R.id.cb1); but where is the listener?
I assume you need to add listener:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
//your code goes here
cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
Log.i(TAG, "Entered onCheckedChanged()");
//other stuff for listener
}
});
}

When we check All then all checkboxes should be checked and when unchecked then all checkboxes should be unchecked, here is the ListView All is also part of the list view, its position is 0 in map list...

please help me I am new in android, I didn't work with CheckBox
[enter image description here][2]
add all selected item ids in your selectedList and then call adapter's notifyDataSetChanged() method
Add boolean value to your MultipleSelect model and change it when you checked or unchecked and for displaying in onBindViewHolder check this value and set checkbox state.
to select all change this value to true for each item in map and call:
yourMultiselectAdapter.notifyDataSetChanged();
same for deselect all - value to true and above call )
i did something like this.
this is y class side code
SelectAll =(Button)findViewById(R.id.footerapproveselectall);
SelectAll.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String btnlbl = SelectAll.getText().toString();
if(btnlbl.equalsIgnoreCase("SelectAll"))
{
// TODO Auto-generated method stub
CustomListAdapter adapter=new CustomListAdapter(Approver.this,AttendanceModelList,1);
lv1.setAdapter(adapter);
SelectAll.setText("Uncheck All");
}else
{
// TODO Auto-generated method stub
CustomListAdapter adapter=new CustomListAdapter(Approver.this, AttendanceModelList,2);
lv1.setAdapter(adapter);
SelectAll.setText("SelectAll");
}
}

I am facing problem in ListView with selecting and then deselecting Checkbox. I have a button in which i am bypassing all the selected items of a list. But i check and then uncheck, it returned as checked.I am using sparse boolean array.
Here is my code-

if(addProductAdapter.mCheckedState.size()==0){
Toast toast = Toast.makeText(this,SELECT_PRODUCTS, Toast.LENGTH_LONG);
toast.show();

else{

for (int i = 0; i < addProductAdapter.getCount(); i++) {
if (addProductAdapter.mCheckedState.get(i) == true) {
//ArrayList<Object> list = new ArrayList<Object>();
// for(int j = 0;j<=productObject.size();j++){
ProductEntity productEntity = (ProductEntity) productObject
.get(i);
ProductsEntity pe = new ProductsEntity();
pe.setProcdut_name(productEntity.getName());
pe.setUnit_price(productEntity.getUnitPrice());
pe.setTotal_price(productEntity.getUnitPrice());
pe.setQuantity("1");
list.add(pe);
// arrayList.add(list);

I am creating a custom listview item with a textview and a check box. Whenever the checkbox of corresponding to a user is selected, I would like to see his name in a toast. I have used the following code :
mUserList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Toast.makeText(ManualInviteActivity.this, position, Toast.LENGTH_SHORT).show();
Users1 user = (Users1) parent.getItemAtPosition(position);
if(user.isSelected()==true)
{
Toast.makeText(getBaseContext(), user.getName(), Toast.LENGTH_SHORT).show();
}
}
});
I don't see anything however, when I toggle the check box. What is the mistake here ?
Thanks
(isSelected and getName are my own functions in the user class)
Adapter Code :
public class UserListAdapter extends ArrayAdapter<Users1> {
static Context context;

public UserListAdapter(Context context, int layoutResourceId, Users1[] data) {
super(context, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
}
public long getItemId(int position) {
return position;
}
static class UserHolder {
TextView txtTitle;
CheckBox cbxUser;
}
public View getView(int position, View convertView, ViewGroup parent) {

// holder.txtTitle2.setText(weather.title2);
// holder.txtTitle2.setText(weather.title2);
// holder.txtTitle3.setText(weather.title3);
return row;
}
}

public class Users1 {
public String title;
boolean selected = true;
public Users1()
{
super();
}

this.selected = selected;

You need to use onCheckedStateChange for Check box.
You need to set a listener to your RadioGroup (not to your list).
Something like this:
RadioGroup radioGroup = (RadioGroup) findViewById(R.id.radioGroup1);
OnCheckedChangeListener OCCL = new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (checkedId) {
case R.id.radio1:
//...
break;
case R.id.radio2:
//...
break;
case R.id.radio3:
//...
break;
default:
break;
}
}
};
radioGroup.setOnCheckedChangeListener(OCCL);
holder.checkbox
.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
Toast.makeText(getBaseContext(), user.getName(), Toast.LENGTH_SHORT).show();
}
});
try this code
public class Customadapter extends BaseAdapter {
Context context;
ArrayList<String> names;
LayoutInflater inflater;
public Customadapter(Context context, ArrayList<String> names) {
this.names = names;
this.context = context;

{

holder.name=(TextView) convertView.findViewById(R.id.textView1);
holder.check=(CheckBox) convertView.findViewById(R.id.checkBox1);
convertView.setTag(holder);
holder.check.setId(position);
}
else
{
holder=(Holder) convertView.getTag();
}
holder.name.setText(names.get(position));
holder.check.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context,""+names.get(holder.check.getId()),Toast.LENGTH_SHORT).show();
}

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);
}
}

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?
code for pojo class
public class Model {
public String name="";
public boolean selected=false;
public String score="";
public Model(String name) {
this.name = name;
selected = false;
score="";
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean isSelected() {
return selected;
}
public void setSelected(boolean selected) {
this.selected = selected;
}
public String getScore() {
return score;
}
public void setScore(String score) {
this.score = score;
}
}
code for Adapter class
public class MyAdapter extends ArrayAdapter<Model> {
private final List<Model> list;
private final Activity context;
public MyAdapter(Activity 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)
{
View view = null;
if (convertView == null)
{
LayoutInflater inflator = context.getLayoutInflater();
view = inflator.inflate(R.layout.row, null);
final ViewHolder viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.label);
viewHolder.scores=(EditText) view.findViewById(R.id.txtAddress);
viewHolder.scores.addTextChangedListener(new TextWatcher()
{
public void onTextChanged(CharSequence s, int start, int before, int count) {
Model element=(Model)viewHolder.scores.getTag();
element.setScore(s.toString());
}
public void beforeTextChanged(CharSequence s, int start, int count,int after)
{
}
public void afterTextChanged(Editable s)
{
}
});
viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
viewHolder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
Model element = (Model) viewHolder.checkbox.getTag();
element.setSelected(buttonView.isChecked());
}
});
viewHolder.checkbox.setTag(list.get(position));
viewHolder.scores.setTag(list.get(position));
view.setTag(viewHolder);
}
else
{

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)
{
}
});
}
